[vsync_opengl_swc_init ERROR] Failed to load a swap control extension #566

Open geekofChangPing opened 4 years ago

Platform:raspberry pi 4b + archlinuxarm

GPU, drivers, and screen setup: GPU：broadcom VideoCore VI Drivers：xf86-video-fbdev

When I try to start compton I get :

[vsync_opengl_swc_init ERROR] Failed to load a swap control extension
[session_init FATAL ERROR] Failed to initialize the backend

I just wonder if compton support this kind of drivers now.

I just got the same error in VirtualBox running ArcoLinux i3. My login screen is black with high contrast, yet my Bspwm installation in the same vm works like a charm. Running VBoxSVGA no 3D to get correct resolution. Just starting my search, and I'm a noob roughly.

Same error here, started some days ago. I already updated it and it still persists...

Loen10 commented 4 years ago

Same, using VirtualBox Artix Linux bspwm. I guess it just can't utilize the drivers on our systems?

ecesar88 commented 4 years ago

My problem is that i was using nvidia-dkms to run the linux-zen kernel. Switching back to normal nvidia drivers did the trick. But it'll not work with nvidia-dkms...

For those who might stumble here,

My case was solved by loading nvidia kernel modules at boot: https://wiki.archlinux.org/index.php/NVIDIA#DRM_kernel_mode_setting

Might be worth to look at: https://bbs.archlinux.org/viewtopic.php?id=257769

This is arch documentation, but more often than not it is useful for other distros.

Hi 4s3ti, can you post what you added to your grub parameters (if you used grub)? I added nvidia-drm.modeset=1 to /etc/default/grub so it looks like this: GRUB_CMDLINE_LINUX_DEFAULT="loglevel=3 quiet splash nvidia-drm.modeset=1"

I have also tried adding that parameter to the grub menu at boot but that also doesn't seem to work, I still get the exact same error with picom.

coolapso commented 3 years ago

As per the documentation above, there are 2 options, the easiest one which is to add the parameter on grub, and for that make sure you follow all the steps at: https://wiki.archlinux.org/index.php/Kernel_parameters#GRUB

The second option which is a bit more complex, but loads the modules earlier, is to add MODULES=(nvidia nvidia_modeset nvidia_uvm nvidia_drm) to /etc/mkinitcpio.conf following the procedures at: https://wiki.archlinux.org/index.php/Mkinitcpio#Manual_generation

either way any of the options worked well for me ... and i am currently loading it with grub to avoid having the pacman hook on arch linux:

GRUB_CMDLINE_LINUX_DEFAULT="loglevel=3 quiet nvidia-drm.modeset=1"

Please read carefully all the documentation, i take no responsibility for any wrong-doing or any issues that may happen
