Failed to initialize output

[rafalz1978]

I cant figure out how to fix the error, Im on Arch linux, KDE Wayland, nvidia. Thank you

Louvre error: [LCompositor::addOutput] Failed to initialize output DisplayPort-2.

[ehopperdietzel]

Hi, are you launching it from a free tty?

[ehopperdietzel]

From the Examples section:

To run any example, switch to a free TTY session using the CTRL + ALT + [F1,...,F10]key combination or execute the $ sudo chvt N command, where N represents the desired TTY number. Then, proceed to execute the compositor command.

[rafalz1978]

so when executing it, my computer is going to sleep, same with examples.

[ehopperdietzel]

Hmm, could you please send me the output of this SRM_DEBUG=4 LOUVRE_DEBUG=4 louvre-views > ~/louvre.log 2>&1 ? It should create a louvre.log file in your home directory.

[rafalz1978]

Louvre error: [LCompositor::addOutput] Failed to initialize output DisplayPort-2.

[rafalz1978]

and the log in KDE from console Louvre debug: [LLauncher::startDaemon] LLauncher daemon started successfully with PID: 2206. unable to lock lockfile /run/user/1000/wayland-0.lock, maybe another compositor is running Louvre error: [LCompositorPrivate::initWayland] Failed to add custom socket wayland-0.

[ehopperdietzel]

1. Ensure you are running it from a free TTY.

   For example, you could switch to TTY 3 with:

   sudo chvt 3

   A black terminal should appear, if not, try another number. Then login to your user account.

2. Finally, execute one of the examples:

   LOUVRE_WAYLAND_DISPLAY=wayland-3 WAYLAND_DISPLAY=wayland-3 louvre-views

   The LOUVRE_WAYLAND_DISPLAY and WAYLAND_DISPLAY environment variables are required because it seems you have another Wayland compositor running (using the wayland-0 socket).

[rafalz1978]

still not working, I disabled my display manager too, same thing.

[ehopperdietzel]

Not sure what could be happening, could you run this again and send me the output?

SRM_DEBUG=4 LOUVRE_DEBUG=4 louvre-views > ~/louvre.log 2>&1

Please this time don't forget to add SRM_DEBUG=4

[ehopperdietzel]

You can press Ctrl + Shift + Esc to exit the examples btw.

I have to reboot computer everytime, because there is no output to monitor, and monitor goes to sleep, but pc is running.

[ehopperdietzel]

Thank you, but you still haven't sent me the complete log, so I can't fully understand what's happening. It seems you're using proprietary Nvidia drivers and it's possible that there's no backend for creating textures with GBM (the log should contain a list of supported formats, but what you've sent seems incomplete).

This means that SRM (Louvre's graphic backend) is failing to create buffers, thus failing to initialize the displays. That's why your window appears black. You can press Left Ctrl + Left Shift + Esc to exit the compositor in such cases, your screen may remain black afterward, but switching tty should fix it.

I think I can fix it by forcing buffer allocation with OpenGL instead of GBM, I'll let you know. For now, I'd appreciate it if you could attach the complete louvre.log file with SRM_DEBUG=4 and LOUVRE_DEBUG=4.

P.S. Nvidia proprietary drivers always seem to have issues, you might consider using Nouveau instead.

[ehopperdietzel]

Hi again, I've made some changes to SRM which I believe will address your issue. Could you please try using the devel branch?

[rafalz1978]

it does not fix the issue

[ehopperdietzel]

Hmm, I'm not sure what the issue might be. If I had access to the complete log, I could provide more assistance.

[ehopperdietzel]

Thank you! It appears that DMA buffers imported from EGL can only be utilized as GL_TEXTURE_EXTERNAL_OES. I've made some modifications to the SRM devel branch to attempt buffer allocation with OpenGL instead of GBM in such scenarios. Please inform me if this resolves the issue. If not, there's one more approach I can explore.

[ehopperdietzel]

Well at least buffer allocation is working now, but I'm not sure why the display isn't initializing. I've added more error messages to help find the problem. Could you try again? Also, you could try running it with SRM_FORCE_LEGACY_API=0, maybe your driver only supports the atomic DRM API.

Okay, thank you. You sent me all the logs except the part where it fails, haha. But no worries, I see you have two GPUs, which I didn't know.

Currently, your Nvidia GPU is creating the buffers and it seems to be failing. I've changed the configuration in the devel branch to use the Intel GPU instead. If there are still issues, I'll force it to use only the Intel GPU for rendering.

When you try it, if it still doesn't work, could you send me the output of running srm-display-info? You can run this program from your desktop environment without any issues.

the log stops on the line below, and monitor go to sleep

�[32mSRM debug:�[0m [/dev/dri/card0] CPU buffer created using glTexImage2D. �[32mLouvre debug:�[0m Font Inter or similar found: /usr/shar

[ehopperdietzel]

Ok, and now?

[ehopperdietzel]

I also have a PC with both Intel and Nvidia GPUs, and it's running smoothly with the nvidia_drm driver. However, I've noticed that I need to use SRM_FORCE_LEGACY_API=0, otherwise, the display connected to the Nvidia GPU becomes very laggy.

[rafalz1978]

its working now, the last patches fixed it

[ehopperdietzel]

Geat! And thank you for your time! Does it work well then? Or is it laggy?
