Re: envyng messed up my karmic
Didn't see what ATI card you have, but unless it's one of the newer HD 3x/4x/5x cards, it is no longer supported with Linux drivers by ATI. Trying to force such a driver install will only corrupt your display -- as you have found out.
The link below has some instructions on removing the ATI drivers and replacing them with the open source drivers:

Ubuntu 20.04, Mint 19.10; MS Win10 Pro.
Will not respond to PM requests for support -- use the forums.
