Короче, я решил проблему: просто отключил встроенную видеокарту.
Нужно снести xorg.conf, а потом создать файл/etc/X11/xorg.conf.d/nvidia.conf с таким содержимым:
Section "OutputClass"
Identifier "nvidia"
MatchDriver "nvidia-drm"
Driver "nvidia"
Option "AllowEmptyInitialConfiguration"
Option "PrimaryGPU" "yes"
EndSection
Section "ServerLayout"
Identifier "layout"
Option "AllowNVIDIAGPUScreens"
EndSection
И после перезагрузки настройки начнут работать (если не робит, то нужно выдернуть кабель и вставить снова).
