It is not the kernel. Before doing the upgrade, I tested 20.10 (and its kernel) using the live image as I usually do and everything went fine, while now I have a system that does not work right regardless of the kernel. Hence, my hypothesis is that something went wrong with the upgrade either wrt the initial initrd or with the grub kernel parameters, or with some configuration file.
The problem is that I am finding trouble in trying to identify what is wrong in my system right now. I have tried a few things like re-installing the kernel, but with no result. I am not even 100% sure that the hang that I see when attempting a regular boot, the lack of the splash screen and the lack of /dev/dri both originate from the same issue. Before I try reinstalling the system from scratch with 20.10, I'd like to spend some more time in attempting a rescue, but I do not have many ideas about where to look. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1901505 Title: upgrade to 20.10 broke haswell laptop (no regular boot, no /dev/dri/card0) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1901505/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
