I have two SSDs. 22.04, 23.10 & Windows are installed on one and I just installed 24.04 on the other. I first created a new partition by shrinking the /home partition and creating the new partition in the now unused space.
I downloaded Gnome-Tweaks to 24.04 and when I changed the pointer, the graphics display blew up and was replaced with a white screen with a picture of a sad face on a computer and:
"Oh no! Something has gone wrong.A problem has occurred and the system can't recover.Please log out and try again."
No mouse pointer is present, only a button that says Log Out, which when pressed takes me back to the login screen.
I reinstalled 24.04 from a Live USB as before. The grub menu is the same as it was, but nothing changed when I logged into 24.04, same white screen. Then I rebooted and selected 22.04, but this now never even gets to the login screen. Instead I get five lines of error text followed by: "You are in emergency mode." I can do nothing from this point.
I can boot fine to Windows and also 23.10, which I'm using to write this. My files are in another partition and seem fine.
Help! Is there a way I can recover my system? Thanks.
