Hello,
I am facing a problem with startX and GTX 1650 driver on my laptop since updating many packages a few weeks back.
My card is detected by the nvidia driver, and CUDA is working.
But if I do startx, X will segfault, abort or hang depending on the version of the driver ( I have tried the distro, 3rd party and nVidia drivers).
If I remove the nvidia-drm module
sudo rmmod nvidia-drm, then startx will work.
However, nvidia-settings shows a blank.
ERROR: Unable to load info from any available system
(nvidia-settings:3121): GLib-GObject-CRITICAL **: 18:21:13.466: g_object_unref: assertion ‘G_IS_OBJECT (object)’ failed
