Formatting a SD Card For Steam Deck

MicroSD Card

It appears that there is a prevalent issue with the Steam Deck corrupting SD cards that can leave them in a unrecoverable condition, this seems to occur mainly on a second formatting rather than the first, so far we’ve not heard anything from Valve about this, but I suspect it’s more likely to be down to the hardware interface rather than a software bug.

Fortunately until we know more you can format your SD card outside of the Deck easily, to do this you will need a Linux live system, assuming you’re not already using Linux, Ubuntu is a good simple choice for this.

Once you have the system running you need to insert your SD card, to identify which device it is use the following command in the terminal:

sudo lsblk

This will show a list of connected storage devices, you can identify the SD card by the size and normally it will be last in the list, in my case /dev/sdg, partitions if there are any will show as /dev/sdg1, /dev/sdg2 and so on.

Once you are sure you have identified the SD card correctly, run the following two commands:

sudo parted --script <device> mklabel gpt mkpart primary 0% 100%
sudo mkfs.ext4 -m 0 -O casefold -F <partition>

The first command creates a new blank GPT partition table, and then a new partition using all the space on the device, <device> should be replaces with your device path, I.E /dev/sdg.

The second command formats the new partition as an EXT4 file system which is what the Deck recommends, <partition> should be replaced with the first partition on your SD card, I.E /dev/sdg1

You can now remove it a insert it into your Steam Deck.

Hot Swapping

Even though Valve have said you can hot-swap SD cards I don’t recommend it, there is no protection against write corruption so you should only remove it when there is no activity or better unmount it in Dolphin first.

Should you get it to the point where you have problems, run sudo e2fsck -pf <partition> to repair it.

Update 30 May

The formatting command used by Valve has changed slightly adding -E nodiscard to mkfs.ext4, this stops it running discard / trim on the SD card, this should speed up formatting, it is still mounted with discard so I don’t think this would effect performance, it may also reduce incidence of bricking.

Installing Emulators on Steam Deck

The Steam Deck is a great device for playing emulated games on, there are a number of options for settings up emulators but I find the easiest to use is EmuDeck.

Installing EmuDeck

Once you’ve download EmuDeck click on the ‘EmuDeck.desktop’ file and it should ask you if you want to open or execute, if it does not right click on it and select Properties > Permissions and check ‘Is executable’ and press OK.

Once run Konsole will appear and begin installing, it will ask you if you want to install in easy or expert mode, I suggest choosing easy, it will then ask you if you want to install your game roms on internal storage or a SD card, I recommend the latter if you have a SD card.

It will then ask if you want to open the ROM manager, a shortcut will be placed on your desktop as well.

To add games go to /home/deck/Emulation/roms/ or for SD card /run/media/mmcblk0p1/Emulation/roms/, there is a directory for each system, place your ROMs in each one.

Once you are done run the ROM manager, open the preview tab and click ‘Generate app list’, wait until it’s finished then if you’re happy click ‘Save app list’, if you return to Steam game mode you should find your ROMs in the non-steam list ready to play.

If it has incorrectly detected a game wrong you may need to rename the ROM and repeat the process, this should not cause any problems with the game itself.

MS-DOS Games

The ROM manager doesn’t work for MS-DOS games, to deal with these run EmulationStation, shown as Emu Deck in non-steam games, if you placed your games under dos they should already be detected.

Keyboard Shortcuts

The shortcuts depend upon what emulator is being used, for a full list look here.


While technically not an emulator sometimes you will want to play Windows games outside of Steam, adding a non-steam game doesn’t always work, to do this the easiest tool to use is Lutris which can also install games for you.

Lutris beta flatpak is now available, to install it do the following in konsole.

flatpak update --appstream
flatpak install --user flathub-beta net.lutris.Lutris//beta

flatpak install --user flathub org.gnome.Platform.Compat.i386 org.freedesktop.Platform.GL32.default org.freedesktop.Platform.GL.default

You can then run Lutris from the KDE Games menu, or add it to Steam, you will need to add a runner first to Lutris, do this in Preferences > Runners > Wine, at this time I’m using lutris-fshack-7.2, once a runner is installed to manually add a game click the add button at the top left, select ‘Add locally installed game’, enter a name and select the Wine runner, under game options set the executable and Wine prefix to a empty directory, the prefix is where the game configuration and virtual filesystem is stored.

You can now right click a game and select ‘Create steam shortcut’ to add it to Steam, all being well it should just work, however this is not always the case, you may need to use Winetricks to install additional components, the Wine Application Database is a good place to start.

Common Problems

Some of the most common problems are:

Game not detectedMost ROMS cannot be placed in sub-directories.
Wrong game detectedRename ROM or directory.
Choppy performance / audioSet the FPS limit to 60.
No game audio (MS-DOS)Run the game installer and set the audio to soundblaster
Game runs too fast / slow (MS-DOS)Press CTRL+F11 / CTRL+F12 to adjust speed.
Yuzu keys not loadingTry place in /home/deck/.var/app/org.yuzu_emu.yuzu/data/yuzu/keys/

Steam Deck Review

I have finally received my Steam Deck, I was fortunate enough to get an early Q2 slot, shipping took about 3 days from the Netherlands, delayed somewhat by the Easter weekend, but eventually it turned up.

It was shipped in a brown cardboard box by GLS and Parcel Force, the box is marked with the companion cube and deck logo, among other identifying info (perfect for thieves), inside is the deck in the case as well as the charger and USB cable, setting it up was quick and easy, although I had to change my password to something shorter since I usually use a password manager with a very long password.

The deck interface is easy to use and largely self explanatory, there is a short usage tutorial and the Aperture Desk Job game designed for the deck provides some additional info so I recommend playing it, it can be finished in 45 minutes or so.

Design and Build Quality

The deck as you would expect of a company like Valve is of a high build quality, the plastic case feels solid and strong, there is a good weight to it but it’s not excessive and should be comfortable for most people, the location of the controls for me is quite comfortable although as a PC gamer it’s taking time for me to get used to them, the bottom buttons are a tad tricky to use so I mainly use them for controls that are not often required, the touchscreen works fine although I largely don’t use it.

The sound quality is very good for such small speakers and there is a good range of volume from very quiet to acceptably loud, although in a very quiet environment you may want to use headphones, the fan noise is moderately loud but not offensive, there have been a lot of complaints which may indicate some bad fans or just variation in tolerance for the relatively high pitch noise it produces.

Thermals are quite good, it gets a little warm around the vents, particularly the top exhaust vent but nothing serious, during heavy usage CPU and GPU temperature is in the 72-75c region with peaks into the 80’s, perfectly acceptable.

Haptic feedback is somewhat of a gimmick in my opinion, it works but it isn’t amazing by any means, fortunately it’s not really required for use, you can turn it off if desired.

The trackpads are quite accurate and usable, I never got to experience the steam controllers but these seem to do a good job in most situations.


Rather than go in to a full list of specifications, which you can look up for yourself, I will just say that for a portable PC gaming device, the Steam deck is the best on the market at the moment, at least in terms of value for money, numerous benchmarks have shown that it can obtain a locked 60 FPS in a wide variety of modern games thanks to the AMD RDNA 2 APU, and is even capable of respectable ray tracing performance in some games, granted this is at the native 800p and with upscaling if you want ray tracing, nevertheless it is exceptionally good for the power it consumes.

The biggest advantage of the deck is it does not limit what you can do with it, it has a regular x86_64 CPU so it’s not limited in software like ARM processors are, in many ways you can consider this to be a highly efficient and portable laptop which gives it great flexibility.

Some people have criticized the display quality saying it should be an OLED panel like the latest version of the Nintendo Switch, I firmly disagree with this, the screen quality and resolution is more than adequate for portable gaming, would I like better, sure!, but not at the added expense and performance penalty for higher resolutions.

Steam will be providing replacement parts at some point through iFixit which will be a nice addition in an age where most products are essentially disposable, hopefully reasonably priced, I also have no doubt that there will be third party hardware as well, clamshell cases, docks, screen protectors and more stuff has already started to appear.

Steam have also been doing an decent job when it comes to RMA for various problems, as typical with Valve however you can expect a general lack of communication and significant delays at the moment, not terribly surprising as there have been numerous launch problems.

Deck Versions

One big choice when ordering the deck is what version to buy, for most of us it’s too late to change that decision, but for those who have not yet reserved this is for you.

It has already been shown that the storage can easily be upgraded, certainly if you’ve ever added parts to a PC you should have no trouble doing so with the deck, which makes the added storage options much less attractive, you can save a very significant amount of money by doing it yourself.

There has been debate over the value of the etched anti-reflection coating available on the top tier version, the general consensus seems to be that it’s only of particular use if you game in brightly lit environments on a regular basis, even then many darker games are still unplayable, one very big negative is you should not use screen protectors with the etched glass as it may damage it and negates the effect, for me this is a complete deal breaker as I want the extra protection of a screen protector, although so far no one has complained of scratches.

The rest of the steam bonuses are certainly not worth the money and the high tier case is near enough identical, in fact I prefer having the black interior, so unless you lack the skill or desire to open your deck, I can only really recommend the 64GB version.


For those worried about storage the MicroSD card interface is sufficiently fast enough for near enough all games, it can operate up to UHS-I speed which is roughly 100MB\s, cards do vary a lot in performance though so you’ll want to look for a card with a V30 or higher marking on it, A2 is also preferable over A1, very fast cards are generally not available in large capacity so don’t bother looking for them.

The Samsung EVO Select 512GB MicroSDXC for example I would consider a good choice and is available for around £60, 1TB cards have a very substantial markup so I would avoid them.

Although Valve say you can hot-swap cards my experience has shown that this is not the case, a card should always be unmounted before being removed to avoid potential corruption, a lot of people have also reported their card being permanently bricked if they format twice in the deck, as such I recommend formatting be done outside the deck.

Steam OS 3.0

Steam OS 3.0 is the latest iteration, unlike the previous versions which were based on the Debian Linux distribution, the new one is based on Arch Linux, practically this means packages are more up to date, although it should be emphasized this is not a rolling release, updates are released by Valve on a fairly regular basis at the moment but in future I hope for better support for using any Linux distribution.

The system is by default read only, which means you can’t install your own packages via the pacman package manager, you can disable this easily but there is a risk any changes would be removed or broken when you update the system, instead flatpack packages are used for installing third party software which works well enough.

Most people are going to spend the majority of their time in the new Steam interface which is essentially a replacement for the big picture mode, this is fairly well designed although is lacking some things such as a well integrated web browser, I have no doubt that this will continue to see improvement over time.

A desktop mode is also provided which gives you a KDE Plasma desktop, I’ve had mixed results with this, with occasional bugs particularly when running a desktop application in steam, the choice of default applications is also a bit weird, most people don’t want to use vim as their main text editor.

The quick access menu allows you to easily access notifications, chat, settings, performance and help, the performance settings are particularly good with an adjustable MangoHud overlay to see what you’re currently getting, control of TDP limit, GPU clock, scaling including AMD FSR, FPS limit and information on the battery.

Battery Life

How long the battery lasts very much depends on what kind of game you are playing, naturally the more intensive the game is the less life you will get, the deck provides a great deal of tuning options so you can optimize for battery life, or performance as you desire, unfortunately there is no way to create per game profiles at the moment, but this should come in future.

Most people can expect 2-4 hours of higher end gaming, with up to 8 hours for lighter games, in many ways that’s better than your average laptop.

There has been some question over battery longevity, lithium-ion batteries do degrade over time and with each charge cycle, however I do not expect this to require replacement for at least two to five years depending on how heavily you use it, it remains to be seen how Valve will address battery replacement.

Game Compatibility

The game compatibility of the deck as it stands with Steam OS is somewhat mixed, most games will at least run, however a number will not, particularly if they implement anti-cheat technology, work is being done to improve compatibility with anti-cheat but this often requires the developer to enable support, some developers have shown a complete disregard for deck and Linux users so 100% compatibility is likely never going to happen.

Windows drivers are not quite complete yet but in future it will be a viable option, although you do lose certain functionality such as the quick suspend / resume and the interface, although I suspect the interface will be available in Windows at some point.

For me personally though I have zero interest in Windows, Linux game compatibility is continuously improving and native Linux support is slowly growing as well, plus you have access to a large variety of emulators so you will always be able to find something to play.

Input Mapping

Most of the more popular games already have input profiles setup, or someone else has already made one for you, however if not or you want to customize you’ll need to make your own profile.

This is fortunately quite easy with a number of templates available for you to look at, I’ve not gone in to great depth with this but looking at what some people have made it’s very impressive.


Somewhat unexpectedly the deck has no security options, so if someone uses it they have full access to your steam account, and any desktop stuff you’ve added, this is a huge oversight by Valve but I suspect it’s simply due to them wanting to quickly get it out to gamers, although considering they also advertise it as a Linux desktop this is not very good.

I certainly would not be comfortable taking it out in a public space, these are asking to be stolen with the huge demand currently, there is also no place for a security lock to be added on the deck.

Usage as a full desktop

The desktop mode is very versatile so with suitable peripherals you can essentially turn it into a full desktop, there are however some caveats to this currently, there is no official dock yet with it slated for being released some time this summer, some people have also experience serious problems with charging when using a USB hub.

The monitor you use also has a big impact on performance, a 1080p monitor will work very well for gaming, anything higher and you are going to get degraded performance, although you can still manage lighter games and video even at 4k.

It’s also perfectly viable to use for work as well, writing, image editing, browsing, light video editing, streaming and more is just fine on the deck, although you do then have to ask yourself, why not use a PC instead?, it could however be useful for those with a weak PC given the current GPU shortage which shows no signs of resolving until next year at least.

Overall Verdict

The Steam deck is a fantastic device if you’re already a PC gamer, if however you’re more of a console gamer or just a casual gamer who wants a very simple experience with no risk of issues, the deck is probably not for you, for those of us who like to tinker with our software and hardware the deck is indisputably the best device currently available.

It will certainly be interesting to see where Valve and other companies go in future as this is a major leap forward in the realm of affordable portable gaming, and Linux gaming.

Overall I’m very happy with the Steam Deck, it’s a perfect device for me when it comes to gaming away from the PC, while it’s far from perfect I’m confident that with Valve and the rapidly growing community the deck will improve greatly with time.

Review Update

Within a week of publishing this review Valve have already released two excellent updates that have addressed some of my main issues, it now has a proper lock screen to provide some security, keyboard localisation (unfortunately missing the UK still) and on the beta branch adjustable screen refresh rate, it’s pretty clear that Valve are working hard to make the Steam Deck the best portable gaming platform ever.

Setting up SSH / SFTP on Steam Deck

Having SSH and SFTP access to your steam deck is very convenient for file transfers and remote administration, setting it up is fairly straightforward.

First you need to have set your password to be able to use sudo, to do this open konsole in desktop mode and type passwd, enter your desired password twice to confirm.

Once that is done you can turn on the SSH server with sudo systemctl start sshd, to login from another system on your network use ssh deck@192.168.x.x, replace with the LAN address of your deck.


To prevent anyone else logging in, edit /etc/ssh/sshd_config, add the following two lines:

AllowUsers deck@
PermitRootLogin no

Restart the server with sudo systemctl restart sshd, this will only allow a login from your local network, if you want to login from the internet then more stringent security is required which is covered in an article here.

To permanently enable the server use sudo systemctl enable sshd.

Useful Linux Utilities 2020

There are a number of very useful tools that people may not be aware of that can be a significant boost to productivity in your day to day usage of Linux, or just plain cool, this article will cover some of the more interesting ones I have come across, all of these are completely free.

If you find any of these useful to you or want to suggest something for a future article please leave a comment.


While regular users of the Linux terminal are probably already aware of this tool it’s hard to understate how helpful it can be at times, the file command simply looks at a file and tries to determine what it actually is, this can be very useful if there is no file extension or you suspect a corrupted file, this should be built into your shell so no need to install it.

Using it is very easy, just type file followed by the name of the file you wish to check, it will then display the detected file type.



One of my favorite torrent clients, provides all the required features without any additional rubbish, it’s designed similar to uTorrent which was a once very popular torrent client, which is now essentially spyware, qBittorrent is completely open source with active development, it’s also available for multiple operating systems.

One handy feature is an included torrent search engine, however it does tend to produce fake results so I’d still advise manually checking them on a trusted website.


Flameshot is a very useful tool for taking screenshots, it provides features such as area selection, annotation and image upload (currently imgur only), all the screenshots in this article and probably most on this website are taken with it.

It still has some way to go though before it can match the best Windows tool for screenshots ShareX, still with it being under very active development I’m looking forward to seeing where it goes.


It continues to surprises me that there are many people out there still failing to make use of password managers, they’re such a massive boost to security and convenience that I consider them to be essential software.

KeePassXC is a modern fork of KeePass, it’s completely open source and has been trusted by many, including myself for a long time, unlike some password managers it stores your encrypted passwords completely offline, as such it provides a high degree of privacy and security.

OBS Studio

Open Broadcast Software Studio is a very versatile tool for recording and streaming video, it’s capable of accepting numerous inputs such as your desktop, games, capture cards, webcams and so on and includes a complete audio mixer, even though it’s free and open source this is easily professional level software with extensive capabilities.

OBS is capable of streaming to most (all?) major platforms including YouTube, Twitch and Facebook, it’s very easy to setup and use making it both suitable for beginners and professionals alike, if you need this kind of software I can’t recommend it enough.


Gufw is a graphical front end to the ufw firewall, which itself is a front end to iptables the Linux firewall, setting up a firewall can be a time consuming process if you’re not experienced in doing so, Gufw provides a nice user friendly way to setup and configure a Linux firewall which will help enhance your security with very little effort, it may not be exactly feature packed but it certainly does the job.

If you don’t already have a firewall setup I would strongly recommend trying this.

Raw Therapee

Raw Therapee is a powerful raw photo processor that is of great value to both professional and amateur photographers, it provides a huge selection of tools for getting the highest quality photos possible from your camera.

It has a very well designed and easy to use interface that puts many commercial tools to shame, combined with being open source and actively developed this is a must have tool for any photographer.
