One day my touchpad stopped taking input so I rebooted my laptop & haven't since been able to return to Kubuntu. When choosing it in GRUB I see (1) the OEM logo for ~1 sec, (2) the Kubuntu splash screen for ~1 sec, (3) the OEM logo forever. I can enter recovery & boot from a live USB. Things I have tried:
- enable & disable secure boot (shouldn't matter w/ EFI)
- disable hibernate & fast boot in Windows 10; performed a cold shut down
- my Ubuntu partition
/dev/nvme01p7has the boot flag per GParted. sudo ubuntu-drivers autoinstall(Nvidia drivers I already had from the working installation)- ran
dpkg&fsckin recovery (Ubuntu partition is mounted, also noted an error I'm ignoring) - ran recommended
boot-repair: see the logs for the diagnostic & repair sudo nano /etc/default/gruboutput
