I am experiencing trouble with a mixture of AMD CPU (and its integrated Graphics) and NVIDIA discrete graphic cards. Since this combo is new on mobile PCs, I could not find enough resources to solve it.
In the post-installation first-time boot, after selecting boot into ubuntu, I stuck with the Lenovo Xiaoxin logo
At this point, sticking in a USB gives a beep unique to the Ubuntu system. But I cannot access any tty.
Boot again with advanced options for ubuntu, still with kernel 5.8.0, I could access the shell. Here, I ran ubuntu-drivers autoinstall, which installed nvidia-driver-460-server. The installation succeeded with nvidia-smi correctly displaying my graphic card info. Reboot, stuck at Lenovo Xiaoxin logo again.
With more digging, I followed amd ryzen 5 mobile nvidia gtx 1050 login loop ubuntu 18.04, still to no avail.
P.S. The Ubuntu20.04 installation runs like butter, the only tiny suspicious logs are included in the photos below.
I apologize for not including a system-generated report, I will try it when I have time. For the time being, I would really appreciate any suggestion on commands/tweaks I could try to make it work.
Thank you! And looking forward to your reply.
