I am trying to dual boot Ubuntu 20.04 with Windows 11. Ubuntu is booting fine after installation but as soon as I install the driver nvidia:535 it stops booting and only a blank screen is visible.
The nvidia driver is working fine but the kernel is too old to drive your 13th gen intel igpu, at least kernel 6.1 needed for that. When no driver is installed, FBDEV is used as a fallback. When the nvidia driver is installed, it’s the only one functional, the internal display getting black because the nvidia gpu is not driving it but the intel gpu.
In general, Ubuntu 22.04 should be used for that device, if you can’t go without 20.04, you’ll have to add the liquorix ppa to install the latest kernel and download and install the needed firmware package manually. http://mirrors.kernel.org/ubuntu/pool/main/l/linux-firmware/linux-firmware_20230919.git3672ccab-0ubuntu2.1_amd64.deb
I have installed liquorix but Ubuntu does not boot after that and freezes. I booted by changing ‘quiet splash’ to ‘nomodeset’.
Now I am trying to install the firmware package you provided as the root user by the dpkg -i *.deb but it gives the following error:
dpkg: regarding linux-firmware_20230919.git3672ccab-0ubuntu2.1_amd64.deb containing linux-firmware:
