latest update created a real mess 20.04 only first 4 letters shown, windows are unreadable

Question

One of the most recent software updates rendered my desktop nearly useless. I can't even get into and work with the terminal since it became virtually unreadable.

I've searched thoroughly for suggestions. I thought I found it with some tweak packages and turning off font antialiasing, but no luck there. Another reply here suggested X11 issues. But I can't really perform any of those because of the terminal issue.

Please help!! what a horrible situation this is.

Does this answer your question? After software update text display only 4 letters or https://askubuntu.com/questions/1328152/ubuntu-20-04-text-splitting-and-screen-flickering/1328913#1328913 — Terrance, Apr 22 '21 at 13:42
thanks for redirecting me. Same problem indeed, somehow my search didn't find that one. Sadly it didn't work for me, but i'm going to take the discussion over there — 100LL, Apr 22 '21 at 14:00
Add information about your graphics card to your question - use "edit". You can copy/paste the output of sudo lshw -class display in your post, formatted as code. — vanadium, Apr 22 '21 at 16:55
While I don't know the issue, you can access a virtual terminal by pressing ctrl+shift+F1 through F7. Log in by typing your username and password. You will be given a shell to run your terminal commands in. — Minecraftchest1, Apr 22 '21 at 14:31
I would love to, but my terminal is now unreadable. I can't recall the graphics card. I think it's an AMD. oh, unless you mean copy the unreadable text from the terminal and paste it...that's clever. let me try — 100LL, Apr 22 '21 at 18:26
Does this answer your question? PC started having screen glitches after update — BeastOfCaerbannog, Apr 22 '21 at 20:09
no, no luck. none of the links shared have done the trick to solve my problem unfortunately. — 100LL, May 03 '21 at 16:24
