My laptop running Groovy (20.10) is affected by this bug as well, but I also can't figure or at least isolate where the problem could be. The hardware is similar to what other people have reported (it's a ASUS K501UQ, with a Core i7-6500U, Nvidia 940MX and Intel HD 520).
It seemed to have started after I installed linux-modules- nvidia-460-generic but even after uninstalling the nvidia drivers it still hangs once in a while. I also tried blackisting nouveau but without success. So I'm not sure this is directly related to any nvidia modules as it was happening even without loading them. I couldn't reliably reproduce the issue with any of combinations between 3 versions of 5.8 kernels installed and nvidia/nouveau. In my case it seems to hand right after loading the kernel and initrd, but I don't get any message on the screen or on the logs and the keyboard is totally unresponsive (I can't switch between tty's). The only data point that seems to be consistent so far is that I wasn't able to reproduce it when booting the kernel on recovery mode. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1911352 Title: Black screen on boot after 20.04 upgraded to kernel 5.8 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1911352/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
