[SOLVED] Disable NVIDIA Optimus

Hello everybody,

I setup NVIDIA Optimus on my laptop using NVIDIA Optimus (xorg.conf and SDDM). It works but because of this bug every time I copy something or any other "spinning animation" is shown the system is basically unusable because of 100% CPU. Yes the link states that this is fixed in xorg-server 1.19 but it still occurs for me on xorg-server 1.20 (or it is something else).

Anyhow I want to disable NVIDIA and go back to Intel but I don't manage to do that. I tried removing xorg.conf and reverting changes to Xsetup but this doesn't work (after reboot NVIDIA is still active). Then I tried to remove all nvidia packages but this causes the system not to boot anymore (waits a bit at starting graphical user interface and then reboots... reboot loop). So what to do?

Thanks a lot.

Best Regards
Thomas

Install bumblebee and bbswitch so that the nvidia card is disabled and configured to not be enabled, or set up a manual xorg.conf that only explicitly loads the intel driver.

Thanks for your reply but could you maybe give me a hint on how to create the intel only xorg.conf? Thanks a lot.

Re: [SOLVED] Disable NVIDIA Optimus

Something like

Section "Device"
       Identifier "intel"
       Driver "modesetting"
       BusID "PCI:0:2:0"
EndSection 

adjust the busid accordingly, FWIW you might want to post the files you've created that are currently still present on the system and a xorg log/journal should the issue persist.
