GLib-GObject-CRITICAL after driver update (Geforce MX250)

[kcn1.71]

Hello, after updating the drivers for the video card on my ThinkPad T490, ubuntu does not see it in the settings.

The driver is installed and loading fine.
You are in on-demand Prime profile. Your X screen is driven by the intel iGPU.
https://download.nvidia.com/XFree86/Linux-x86_64/470.74/README/primerenderoffload.html

Switch to “Performance Mode” for your nvidia GPU to render the graphics and pass it to the iGPU for display.

[kcn1.71]

Before the update, I saw both video cards in the settings, and now the Intel video card is listed there twice (even in Performance Mode), and before the update, I saw information in PRIME, but now it is empty

You’re not in offload mode but Xorg is crashing and the DE is falling back to Wayland

There’s also a log from an ealier, working boot captured and neither
kernel
nvidia driver
Xorg
have been updated. What exactly has been installed on update?
Overall, the issue seems to be with the intel igpu, it also takes ages to initialize after firmware load so it’s not even available sometimes.

[kcn1.71]

After installing ubuntu, I had open source drivers installed (bottom in the picture), I installed proprietary 470 (because they are signed tested)

After that, ubuntu started up as it should and displayed both video cards in the settings and all parameters were displayed in nvidia-settings. In nvidia-settings, I enabled perfomance-mode and rebooted, after that the video card disappeared from the settings and nvidia-settings is now empty. Tried reinstalling the opensource/proprietary drivers several times - didn’t help

[generix]

It’s some bug with the Xserver/modesetting driver.
Please check if adding the drivers to the initrd helps, add the lines
i915
nvidia
nvidia-modeset
nvidia-drm
to
/etc/initramfs-tools/modules
and run
sudo update-initramfs -u

You can switch back to offload mode using
sudo prime-select on-demand

[kcn1.71]

Added. After reboot, there are NVIDIA Corporation GP108M [GeForce MX250] / NVIDIA GeForce MX250/PCIe/SSE2 in Ubuntu Settings and a lot of information in nvidia-settings

[generix]

You also switched back to offload mode. Does performance mode also work?

[kcn1.71]

Performance mode remained selected in the nvidia-settings after the reboot. How can I check this for sure?

[generix]

The terminal window is blocking the view on the interesting info.
To check for the nvidia gpu to be primary, run
glxinfo |grep vendor
should output “Nvidia” for performance mode, “Intel” for offload mode.

[kcn1.71]

piletskiy@piletskiyPC:~$ glxinfo |grep vendor
server glx vendor string: NVIDIA Corporation
client glx vendor string: NVIDIA Corporation
OpenGL vendor string: NVIDIA Corporation

[generix]

Seems fine.

[kcn1.71]

Perfect :) And now I see GPU Utilization > 0, was zero before…
Now I have to do the same for windows 10…

Thank you very much for your help!

which post should i mark as solution?
