I have latest ubuntu release (20.04) with gnome fallback session. After reboot I got all letters scrambled. On desktop, in terminal, in explorer all files have only first four letters. I don't know how to describe it better. In firefox it's alright, menus have all letters.

It's like that: enter image description here

Update: I tried solution from that page: https://forums.linuxmint.com/viewtopic.php?p=1996836

I did: sudo ppa-purge -d focal ppa:oibaf/graphics-drivers

Result: I can not get to Ubuntu any more...it's stuck on boot, just like in my previous thread: Ubuntu 20.04 stuck on boot

  • What version of Ubuntu? Both 20.04 and 20/10 can be called the latest. – David Apr 03 '21 at 10:50

    I can not check in my system settings, because words have only 4 letters... – Mersault Apr 03 '21 at 15:40
  • Well you can once this is fixed. Just keep that in mind for any future questions. – David Apr 03 '21 at 15:47

  • You can have an entirely functional command line to work on by using a virtual console. If you have GDM3 then the virtual console is Ctrl+Alt+F3, and can return back to the graphical session with Ctrl+Alt+F2. If you have lightdm, subtract 1 from the F keys, correspondingly. – Levente Apr 04 '21 at 13:35
  • I tried commands from the above link, but did not help. I also have Radeon graphic card...the link in french I can not understand – Mersault Apr 04 '21 at 17:04
  • Now, to continue with repair attempts, you will need to use either a "safe graphics mode" (by editing the boot entry in the Grub menu (press e while it's highlighted) before pressing Enter on it (and adding the nomodeset param (before the part that says "quiet splash"))). All the while you are doing this, keep an eye at the text at the bottom of the Grub screen: it contains instructions. Or, alternatively, one could also use the "recovery mode", and its "drop to root shell" feature: https://wiki.ubuntu.com/RecoveryMode – Levente Apr 04 '21 at 18:13
  • Adding nomodeset doesn't help...I'm still stuck at boot...I can get terminal with CTRL-ALT-F3...problem is I can't install xserver-xorg-video-nouveau because of unmet dependencies (broken packages) xorg-video-abi-24 and xserver-xorg-core. I tried to install dependencies, but could not... – Mersault Apr 04 '21 at 19:10

I solved problem just like I did in the "stuck on boot" thread...I removed packages that were dependencies for xserver-xorg-video-nouveau, installed them, installed xserver-xorg-video-nouveau and instaled gdm3.
