Update for https://www.reddit.com/r/linux_gaming/comments/1ni062k/flickering_black_bars_when_streaming_on_discord

Just a disclaimer: while I have done some testing, I haven't been able to do full-blown practical testing with a friend (since its hard to watch my own stream while gaming lol). If other people can try the following and confirm my findings, I'd greatly appreciate it!

Short answer: most people identified GNOME's window manager, Mutter, as the primary cause of the issue. I don't think that's wrong, but there's something else at play that is making the issue significantly worse than it should be. I'm not yet sure what the offender is, but you can avoid installing it by installing just the `gnome-session` and whatever applications you use instead of the entire `gnome` package.

Long answer: So because everyone was saying Mutter is the issue, I sought replacing it with KWin, since through prior testing I know KWin with KDE doesn't have this issue. However, while you could have probably replaced Mutter with KWin on Gnome 10-15 years ago, it seems impossible now (at least not without excessive tinkering I don't have the energy for lol). During this, I ended up uninstalling all of gnome, installing KWin, then installing just the gnome-session and tried to start it with KWin. It would kinda start, but it'd just give me a black screen with a cursor lol.

In defeat, I decided to kinda just keep working with what I had. Remove any extra bloat the default gnome package may have. So I uninstalled KWin, and only reinstalled and enabled GDM before rebooting. This installed Mutter, but very little else.

But, when I went to test the flickering issue, it was gone. Not entirely gone, but it only flickers if you have two windows open and rapidly move your cursor between the windows. (Note: I was only streaming one of the windows, not the whole screen). This effectively eliminates the issue, as I won't be constantly changing windows when streaming games lol, and even if I do the flickering is much more manageable, whereas before it basically would make my stream unwatchable.

I can't guarantee this will be the same for all distros since I'm on Arch, but I'm sure it'll be the same for any Arch-based distros). From here, I plan on passively working to figure out what the offending default package is, just if I end up installing it later.

Just to itemize the effective steps I took, in case other people want to try it:
1. Uninstall everything gnome, reboot.
2. In the TTY, install gnome-session and gdm. run `systemctl enable gdm`. reboot.
3. Login like normal, install anything extra you need like gnome-backgrounds and gnome-control-center. You may have to use the TTY if you were previously using the default gnome terminal emulator.
4. And that is all I did :)

I don't fully recommend doing this for everyone unless you're ok with any potential breakage just cause there may be issues that arise due to the lack of all the default gnome suite, but for now this has been working fine for me. Also not going to mark this as "answered!" since the exact cause is still unknown, and this is a less-than-ideal solution for now. Plus I havent done extensive testing to 100% confirm it even fixes the issue lol.

I installed a few games and extracted the files no problem however when I then try and run it on wine, bottles, steam or even lutris it will not work. It seems like it runs but then nothing happens and it says I can run it again. This doesn’t happen witht the other games I’ve ran on these apps and used so why wont it with this one?

Hello guys. I am using Ubuntu 25.04. I use Heroic Games Launcher for GOG games and Steam for Steam games. This post is for Steam specifically.

I had GTA IV (not V, not VI) installed on my external HDD. Right now, the game does not show up to me. It has been this way for some time.

Honestly, I genuinely don't remember deleting this game? It's also not very large, less than 30 gb, so I don't see a reason to have deleted it.

Any way to check whether the files are still there but not being detected, other than browsing ten thousand proton prefixes?

so im running plasma 6.4.5 with kubuntu 25.04, using steam and proton 9.04 the game worked fine the last time i played it a couple weeks ago abd actualy worked great my first run last night but frame rated suddenly dropped and im not sure whats going on, ive ran all my updates, verified the install, reinstalled the game, double checked my nvidia drivers. im running it in windowed mode on a tv(i use a large tv instead of multiple monitors i just corner snap my windows, resource usage never goes above 30% and temps look good, sometimes the game launches and it wont go above 40fps and other times it launches and wont go above 20fps, ive been trying to figure it out all night.

So I just bought a new gaming mouse that is capable of going up to 8000hz for polling rate, but even with limited FPS, I just get a lot of micro stutters while playing Overwatch even on 2000hz polling rate (basically anything greater than 1000). I set my FPS to unlimited and sure enough, I drop from ~550fps straight down to 400fps when I start moving my mouse on 2000hz polling rate. On Windows, I do not drop even a single frame on 8000hz polling rate, so it is neither my CPU and Overwatch itself. I did notice that using X11 does lead to less frame drops, but I rather get this running under Wayland if possible.

I am running Proton GE 10.15 , I tried running the game through Proton Experimental and Hotfix, but I still get frame drops.
KDE Neon 24.04 on Wayland
Ryzen 7 5700X3D on a Radeon RX 6700
CPU and GPU governor are set to their max
kernel: 6.14.0-33-generic
I did try running the game through bottles (used to do it through lutris once upon a time ago), but the battle(dot)net launcher kept crashing on startup, so I will tackle this later.

I haven't asked linux related questions in a good while, so if I have missed out on information about my system, let me know and I will provide it! I would also like to get 8000hz polling rate running without a hitch, purely out of interest though, I know it's overkill lol.

Is there a way to configure MangoHud to output to a VR headset? By default, MangoHud outputs the data on my (flat) PC screen. Or is there another performance monitor tool for Linux Mint + Steam + ALVR + Meta Quest 3?

So for context, I have a Ryzen 5 5600x, 16Gb RAM, and an RX 7800 xt with 16Gb VRAM. At 1440p I'm getting 40fps, so I want to run the game at 1080p (since benchmarks I've seen show 60+ fps for similarish systems to mine at that resolution) and upscale. My main issue is that this game just won't allow it - I have a 3440x1440 monitor and the options just don't appear in the drop down menu.

I attempted to work around this by using gamescope, however despite rendering at a lower resolution the performance seems to be slightly worse (struggling to hit 40). The launch commands I used were:

gamescope -w 1920 -h 1080 -W 3440 -H 1440 -b -F fsr --force-grab-cursor -f --%command% -nostartupmovies -nosplash

I have fiddled with settings for a couple hours however I can't seem to find a solution - I would appreciate any advice or being pointed in the right direction. Thanks!

Edit: another piece of information that might be useful - frame generation feels significantly better in gamescope compared to running the game normally. I find myself almost completely unable to aim by default with frame gen enabled.

Hello again Linux_Gaming!

A couple of years ago I asked for some Linux testers for my first game, World Turtles, which was eventually released (including native Linux) in May 2023 (into EA, April 2024 into 1.0). The response to my request was extremely positive, and I am very grateful to the knowledgable Linux gamers that took time to help out a solo developer!

I've since been working on my second game, Minor Deity, for about 17 months. On a technical level it is much more complex than World Turtles, making excessive use of bursted jobs on threads to allow me to handle 13 million underlying micro-square-grid point and 160 thousands underlying macro-hex-grid points, up to 10 million objects spread out on a huge map, including 50 thousand animated units. I actually started the game because I made an in-depth study of threaded jobs due to issues World Turtles was having on some PCs, leading to negative reviews. In Minor Deity, all of the terrain itself is editable (stamp islands / land masses, detailed adjustments of elevation, trees, smaller vegatation, animals, buildings, people, crops, roads, fences, walls and towers, localised dynamic weather, etc.), so it's basically a gridless, interactive, world-building sandbox with large maps - not that it's *as* impressive, but think "Tiny Glade on a macro level".

I would love to eventually also release it for native Linux, but would need testers to help me figure out whether that's even viable given the "underlying architecture" is so much different from what I've had before. I will be using my Discord server to run a Linux (and later general) Playtests, so if you are willing to assist in determining how viable this game is for Linux, I would appreaciate it if you could join the Discord server and pick the "Linux Tester" role under "Onboarding & Roles".

If you would just like to follow the game and see whether we're able to make it to native Linux, you're also more than welcome - every bit of support helps!

As always, thanks for your time.

PS. I am sorry if this violates any rules - no hard feelings if this post is deemed spam and removed. However, having already released a game with native Linux after assistance from this subreddit, I would love to try and include native Linux again.

Hi,

I'm finally done with windows for obvious reasons. My main thing that prevented me to switch earlier is wanting to be able to game.

I've been trying some games but no luck yet. The games simply wont launch in steam at all.

I installed linux mint, nvidia drivers and Proton GE (selected it in the compatibility settings)

Still no luck whatsoever.

Im trying to run https://www.protondb.com/app/973760?device=pc as an example.
I have a 970 GTX.

What am I missing?

Should I just install a different distro? Or Steam OS?

Edit: I am on driver 580 now (was on 550 previous) still not working.

Stellaris does work.

Am I correct in assuming this game should be able to work ion linux mint f it has steam deck compatibility?

Relatively new to PC gaming. I have a desktop (windows) and hand held (Legion Go S Steam edition).

How is it that I can(and have) play Halo Infinite that uses Kernel Level Anti-Cheat and it's compatible (per Steam description), but I can't play Battlefield or Call of Duty that's also uses Kernel Level Anti-Cheat?
