I install F32 KDE and my original plan was use the internal video for the desktop GUI, and only use the nvidia card for CUDA… (now, I’m willing to compromise). I follow the fusion guide for drivers install and as far as I can see, the driver and CUDA is working… Next, I plug a external monitor and, to get video on it I added the Option “PrimaryGPU” “yes” to the X11 nvidia.conf file (Can someone clarify me if the optimus things apply to me having an AMD not Intel chip?)
But, in this config, I get frequently freezes an crashes, like this one:
Can you go into bios and disable the amd GPU? This is the first I have seen a machine with both AMD and Nvidia GPUs. You do not have the common intel/nvidia pairing and those work well together but no one has ever needed AFAIK to prevent loading the intel i915 driver. What I suspect is that you will have to allow the amd driver to load then specify the nvidia as primary GPU as you already did. It should just work that way, using nvidia for both screens.
No, the optimus does not apply to your machine, in fact it only applied to machines during a certain time period with specified hardware config.
I cannot see the external monitor. This is the xrandr output
Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 16384 x 16384
eDP connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 344mm x 194mm
1920x1080 144.00*+ 60.00
I’m going to install nvidia drivers and see if something is different.
In here set the monitor and mark it as Enabled and Primary (if you want to see the main desktop on the external monitor), or leave Primary unselected to use the laptop display as primary and the external monitor as secondary and see if you have any issues.
