I’m running a Lenovo ideapad laptop with AMD Ryzen 5 4600H processor + Nvidia GTX 1650Ti. I dual booted the system with Ubuntu 21.10 which uses the linux kernel
5.8.0-40-generic. I installed
nvidia-drivers-460 from the additional drivers settings in Ubuntu. I also have a secondary monitor connected to the HDMI port.
My laptop works fine when set in
prime-select nvidia, The monitor displays the screen, I am able to open
nvidia-settings and modify the settings and also see
nvidia-smi . But it consumes too much power. Therefore, I tried to switch to the integrated AMD renoir graphics card .
Once I run
prime-select intel and restart the system, the second monitor is not being detected. I tried deleting
/etc/X11/xorg.conf but it didn’t help. I also tried switching from gdm3 to lightdm but that also didn’t work.
Any way I could get he monitor working?
My xrandr output:
