A common issue after updates is a mismatch between the kernel and the NVIDIA driver, which often causes a black screen.
Try:
Boot with the previous kernel.
Remove the NVIDIA driver (check eopkg li nvidia):
sudo eopkg remove nvidia-glx-driver-current
(if you use another version, e.g. nvidia-beta-glx-driver-current, adjust the command accordingly)
Reboot – the system will fall back to nouveau.
Update the system:
sudo eopkg up
Reinstall the NVIDIA driver:
sudo eopkg it nvidia-glx-driver-current
(or nvidia-beta-glx-driver-current if that’s your version)
Reboot again.
Should I understand that 920 refers to eopkg hs -t 920? The error occurs because the package name changed to gstreamer-1.0-plugin-libav.
If needed, install it with:
sudo eopkg it gstreamer-1.0-plugin-libav
