When trying to boot normally from grub I get a black screen when it should be showing me the password field for my boot partition. Entering the password anyway does not boot Ubuntu.
When I delete
quiet splash from the boot options then the last line I can see is about EHCI, but no errors are visible. At that point the boot process hangs and the only thing that I can do is reboot with CTRL+ALT+DEL.
Booting with the recovery mode works as expected. The dialog asking for the root partition password appears and everything works as expected after I select the resume option twice.
I tried running boot repair and get this paste from it: http://paste2.org/CVcxaMpp
The BIOS is set to boot from the correct disk /dev/sda
I have recently upgraded my graphic card from an old nvidia to a newer nvidia card, but I am not sure that the problems started at that point.
I have tried to swap my keyboard and mouse before booting to rule out that they are the problem. This didn't change anything.
I have tried to disconnect all disks besides the main ubuntu disk, but that didn't help either.
Changing the boot options from
quiet splash to
nomodeset and adding a delay to /etc/init.d/sddm
# Wait for plymouth if running [ -x /bin/plymouth ] && /bin/plymouth quit sleep 2 call do_start_cmd
just let me boot almost normal. Doing only one of these does not work. Unfortunately I don't get a nice looking boot process when I remove
