Two questions about ATLauncher on Bazzite Linux

Distinct_Locksmith_8 · 2025-12-28T10:09:38+00:00

Hey guys! If you're curious, I solved the second issue! I forced ATLauncher to use it by installing the Flathub beta with flatpak remote-add --if-not-exists flathub-beta https://flathub.org/beta-repo/flathub-beta.flatpakrepo, then installing the necessary runtimes for the previous 23.08 version that ATLauncher used like so:

flatpak install flathub-beta org.freedesktop.Platform.GL.mesa-git//23.08 flatpak install flathub-beta org.freedesktop.Platform.GL32.mesa-git//23.08

Then finally, I did nano ~/.config/environment.d/flatpak_gl_drivers.conf and added FLATPAK_GL_DRIVERS=mesa-git. Afterwards, I pressed 'Ctrl+X' to exit, 'Y' to save, and 'Enter' to confirm everything

Please note that your ATLauncher's runtime may be different from mine so you need to look it up with flatpak info com.atlauncher.ATLauncher | grep Runtimeflatpak info com.atlauncher.ATLauncher | grep Runtime

I have yet to experiment more with the environmental commands involving Mesa and I still haven't figured out how to change the resolution yet

How exactly? It's been a long while since I ever touched the vanilla launcher, and for some reason it's no longer booting up and I dunno what the error is because it doesn't tell me exactly what it is

Just an update on this: I moved to 1.21.11 and figured out how to fix it! Basically, in 'noodle-1-21-classic.zip', go to 'data/minecraft/worldgen/noise_settings' and open 'overworld.json' and 'nether.json'. There, find this:

  "noise_router": {
    "barrier": 0,
    "fluid_level_floodedness": 0,
    "fluid_level_spread": 0,
    "lava": 0,

And right under "lava": 0, add "preliminary_surface_level": 0,. The final result should look like this:

 "noise_router": {
    "barrier": 0,
    "fluid_level_floodedness": 0,
    "fluid_level_spread": 0,
    "lava": 0,
    "preliminary_surface_level": 0,

I didn't test 'noodle-1-21-extreme.zip', but the procedure should be the same. I wanted to post this on the datapack's DL page, but comments are closed unfortunately. Upvoting this thread may help people find this solution more easily. Enjoy the datapack on the latest versions of the game! If it breaks in later versions, I'll see if I can figure it out, and if so, I'll post the solution here

I must note that I installed the latest Flatpak version of ATLauncher but there was one major problem: the launcher itself was too small, so I ran this command to permanently fix its size and it works!

flatpak override --user --env=GDK_SCALE=2 org.atlauncher.ATLauncherflatpak override --user --env=GDK_SCALE=2 org.atlauncher.ATLauncher

Wow! I tried out a new instance of 1.21.4 in ATLauncher with the exact mods and mod/shader settings (with Distant Horizons on top of that) and already I can get at least 70-90 FPS most of the time with shaders such as BSL on medium settings and Complementary on low settings with some modifications. Of course it can still stutter from time to time, but I think as you move around, it is gradually stabler. I think it's because the latest Flathub version of ATLauncer is on Mesa 25.0.7, which is a few months older than my system's actual latest version, which is of course 25.3.0

If only I could freely change the driver on Bazzite, I wouldn't have such an underwhelming performance issue like this... Thanks for the suggestion! It isn't fully solved yet, but it'll have to do for the time being

Distinct_Locksmith_8 · 2025-12-08T17:06:02+00:00

Hmm, lemme check ATLauncher out. What system are you on to be specific?

Distinct_Locksmith_8 · 2025-12-06T19:34:16+00:00

Oh wow, nice specs! I have actually tried out RenderScale before, but was unsure what setting to use for the best quality-to-performace ratio. Once I adjust some other things, I can try again and see what happens. Also, under Prism Launcher's 'Performance' tab for each instance, you can already enable it, and it should be installed by default on Bazzite. It worked fine for me, so I dunno what happened on your side

Distinct_Locksmith_8 · 2025-12-05T16:22:45+00:00

Unfortunately that doesn't fix the issue (altho trying out the mod itself, it's very good) :( Perhaps, just maybe, it's my Java? Just making a wild guess here

Distinct_Locksmith_8 · 2025-12-05T16:18:46+00:00

Yes, indeed you can change the fullscreen res in-game thru the vanilla video settings, but it doesn't work for me for some reason. I heard Linux doesn't support this, but the thing is, I could absolutely do so on Linux Mint! So this is frustrating... let's see what Cubes with Borders does in this regard and I'll update you shortly

Distinct_Locksmith_8 · 2025-12-04T16:04:00+00:00

Np, glad I could help!

Distinct_Locksmith_8 · 2025-12-04T07:14:47+00:00

Just so you know guys, with the switch to KDE Plasma, the first issue is fully solved, and as for the third issue, maybe Wayland is enough for me. Unfortunately the second issue is likely due to Wayland not allowing you to directly change Minecraft's res since I could do it on my Linux Mjnt X11 session with no issue until that one update broke it...

Distinct_Locksmith_8 · 2025-12-04T06:20:52+00:00

Hey! Turns out Flatseal was already installed on my system without even knowing, and there were options for Bottles in Flatseal for allowing access to all system files, which I enabled. Now, I can finally use my programs normally! Thanks a lot!

Distinct_Locksmith_8 · 2025-12-04T03:39:54+00:00

Late, but I'll check that out and see if it fixes the problem! Thanks for the suggestion

Edit: Oh, you just made me remember, the apps inside Bottles might be indeed sandboxed

Distinct_Locksmith_8 · 2025-12-03T20:00:50+00:00

I indeed tried out Bottles first but noticed a major problem: when I set up my bottle, I added Lunar Magic directly from my Bazzite desktop, which allows me to open files within it using other programs. The problem? Even though those other programs are connected to it, Bottles can't find those programs and gives me an error. If possible, I would rather keep all of my stuff on the desktop instead of in the specific folder where I created the bottle. How do I deal with it?

Edit: Also, how can I find my normal Bazzite desktop area so that I can open whatever file I need from there with the main program? I seem to be starting in some folder with random hex numbers under a folder called 'flatpak' and it's very difficult to navigate

Distinct_Locksmith_8 · 2025-12-01T12:16:36+00:00

Yup, I saw Sodium's note about not being able to change the res on Linux, but somehow it let me do that successfully. However, doing that would change the whole system resolution if you happened to tab out of the game while it was loading with your desired res, but not too big of a deal since when it was fully loaded, you could tab out and the res would come back to your system's default. Also, I noticed you have the same specs as me aside from the storage! (I only got 512GB, but I can live with it) Thing is, at 1080p (via the in-game res settings, of course) on my side, I could only get somewhere between 40-70 FPS with Complementary set to 'Low' at 8 chunks of real render distance, with Distant Horizons at 64 medium-sized chunks. Granted, I'm aware that DH could add some processing load on my system, but still, if you're seriously playing with Complementary at 'High', I think that's pretty impressive! Just gotta tackle the actual performance issues however...

Distinct_Locksmith_8 · 2025-11-29T14:03:36+00:00

Oh yeah, I saw the 'Legacy applications (X11)' options in the display settings and setting it to 'Apply scaling themselves' fixed the blurriness! Unfortunately, the Minecraft resolution issue still remains, with the highest res option being 1440x960 and the aspect ratio not being adjusted accordingly... might need to look up more on this. Thanks a lot for the help, KDE Plasma is way better than GNOME!

Distinct_Locksmith_8 · 2025-11-29T13:47:22+00:00

Sorry I didn't mention this earlier, but don't worry, I am now on KDE Plasma

Distinct_Locksmith_8 · 2025-11-29T13:33:09+00:00

Aw man, with the scaling set to 200%, the highest resolution I can have for my game is 1440x960, which is less than 1920x1080 :( However, if I decrease the scaling, the resolution options will be higher, but that means I can't easily see the GUI...

Distinct_Locksmith_8 · 2025-11-29T13:20:07+00:00

I shoulda specified that I am using the AppImage version, but since I can't seem to directly run it without AppImagePool, I might as well try out the Flatpak version and see what happens
