[Bug]: Missing DRI3 Support #168

Open flo-sem opened 2 weeks ago

flo-sem commented 2 weeks ago

Describe the Bug

Certain games on steam ('Cult of the Lamb' for me) start and crash immediately. After tinkering around with the launch options, my best guess for this is an issue with Vulkan. (As PROTON_USE_WINED3D=1 %command% resolves this). After installing lutris for testing, i encountered this Note in the terminal: vulkan: No DRI3 support detected - required for presentation

After looking at Issue 52 , i tried setting the proton version to v7... This resulted in the game opening in a black screen, with a popup showing:

Switching to resolution 1920x1080 failed
Screen: DX11 could not switch resolution (1920x1080 fs=0 hz=0)

Steps to Reproduce

  1. Enable Steam Play support for all games in the steam settings.
  2. Download Cult of the Lamb
  3. Start the Game

The Lutris message is reproduced by

  1. Installing lutris
  2. running lutris from the terminal

Expected Behavior

The game should launch as expected. Maybe consider enabling DRI3 as shown here.

Could you try creating a file in your init.d directory with these contents:

sudo sed -i '/^Section "Device"/a \
    Identifier "Intel Graphics"\
    Driver "intel"\
    Option "DRI" "3"' /etc/X11/xorg.conf

If this fixes it for you i'll see if i can patch it in. You can also just edit the /etc/X11/xorg.conf if thats easier and restart the container, just be sure not to recreate the container as changes will be lost

flo-sem commented 2 weeks ago

Gave it a shot, however then the vnc website can't connect to the server anymore, logs below.

If I edit the xorg.conf file itself, it resets itself after the container reboot.

I also tried creating a new config files in /etc/X11/xorg.conf.d/ , that however didn't seem to have any effect, as running vkcube still results in:

Selected GPU 0: Intel(R) UHD Graphics (CML GT2), type: IntegratedGpu
vulkan: No DRI3 support detected - required for presentation
Note: you can probably enable DRI3 in your Xorg config
Could not find both graphics and present queues

Are you able to check if it's even running off the igpu? I have the same issue, included --device=/dev/dri in extra parameters with intel pentium 8505 (intel_gpu_top installed on unraid).

When running any game that requires proton, they instantly crash and go back to the green play button. When including the Wine parameter you mentioned in launch options, the games launch but run extremely poorly. In the unraid homepage menu the iGPU also shows no activity (also have --device=/dev/dri in plex extra parameters and when transcoding gpu shows activity) suggesting the game running off purely the CPU.

vkcube shows: [default@SteamHeadless ~]$ vkcube Graphics Selected GPU 0: Intel(R) Graphics (ADL GT2), type: IntegratedGpu vulkan: No DRI3 support detected - required for presentation Note: you can probably enable DRI3 in your Xorg config Could not find both graphics and present queues

But steam system information shows: Video Card: Driver: Mesa/X.org lImpipe (LLVM 15.0.6, 256 bits) Driver Version: 4.5 (Compatibility Profile) Mesa 22.3.6 OpenGL Version: 4.5 Desktop Color Depth: 24 bits per pixel Monitor Refresh Rate: 50 Hz VendorID: 0x8086 DevicelD: 0x46b3 Revision Not Detected Number of Monitors: 1 Number of Logical Video Cards: 2 Primary Display Resolution: 1920 × 1080 Desktop Resolution: 1920 × 1080 Primary Display Size: 20.00" x 11.22" (22.91" diag), 50.8cm x 28.5cm (58.2cm diag) Primary VRAM Not Detected

I feel like there may be a config issue somewhere, but not sure how to fix this

flo-sem commented 2 weeks ago

I looked into @1mthesun 's comment, running "Cult of the Lamb" (Proton) and "Enter the Gungeon" (Native), i found that while the 4 bar graphs in intel_gpu_top (Render/3D, Blitter, Video, Video Enhance) did in fact not show any utilisation, The above "IMC reads/writes" section showed a drastic increase after launching a game, as well as the amount of Watts used by the CPU (for both games).

I dont think a lack of iGPU utilisation is causing this issue...

(Sorry for closing and reopening, must have pressed the button on accident)

Any activity on this issue?

Hi, I'm facing the same issue with Marvel's SNAP game, I can run it (with proton 7.0-6 and "PROTON_USE_WINED3D=1 %command%" launch option) but it's reaaaally slow. vkcube command gives:

I tried playing with xorg.conf (get reseted on container restart) and xorg.conf.d/20-intel.conf that stick after restart but does nothing. Steam information shows:

If I run without "PROTON_USE_WINE3D" it gives:

Switching to resolution 1680x1050 failed

I'm not sure of how to get Proton logs or where ot find them, if you can help me I'll provide them !

Did you made any progress on your side ?

I followed @alansari s comment trying to modify the Xorg config, but it had no effect just as you are describing

niawag commented 4 hours ago

I tried to mount the xorg.conf file directly (to force it's content) but the container won't start because of "70-configure_xorg.sh" that try to edit the file and fail. So I edited "70-configure_xorg.sh" from inside the container by forcing it to copy my xorg.conf file: 

    if ([ "X${monitor_connected}" = "X" ] || [ "${FORCE_X11_DUMMY_CONFIG}" = "true" ]); then 
        print_step_header "No monitors connected. Installing dummy xorg.conf"
        # Use a dummy display input
        # cp -f /templates/xorg/xorg.dummy.conf /etc/X11/xorg.conf --> original line replaced by mine hereafter
        cp -f /home/default/xorg.conf /etc/X11/xorg.conf
    fi

It's running as before with the same exact problem so enabling DRI 3 in xorg.conf does not seem to solve our problem. Here is my xorg.conf file for reference: 

Section "Device"

    EndSubSection
EndSection

Section "Device"
    Identifier "Intel Graphics"
    Driver "intel"
    Option "DRI" "3"
EndSection

Is there something I should change in it ? Are the two Device sections ok ? (I tried to remove the first Device section, xorg process is not starting) I also tried with this xorg.conf with the same result (working but no DRI3 support):

Section "Device"
    Identifier      "Configured Video Device"
