Hardware: RTX3060ti, Ryzen 5 2600 on fresh install. Working monitor is connected via DisplayPort, non-working one is connected via HDMI.
I have nvidia-driver-455, 460 and 465 installed.
prime-select query shows
nvidia but nvidia-settings displays a blank box with the text:
ERROR: Unable to load info from any available system (nvidia-settings:6906): GLib-GObject-CRITICAL **: 11:18:55.620: g_object_unref: assertion 'G_IS_OBJECT (object)' failed ** Message: 11:18:55.623: PRIME: No offloading required. Abort ** Message: 11:18:55.623: PRIME: is it supported? no
lshw gives me:
configuration: driver=nvidia latency=0
So I have the newest drivers, they are being used and I've had this hardware configuration working correctly on an older install.
What else can I try?
