I tried to install FGLRX drivers on Ubuntu 13.04, but that didn't work out.
I then went back to the open source drivers (via
update-manager) but I couldn't boot into a graphical OS.
I got a black screen with a prompt to log in.
I got in, launched
lightdm manually, and reinstalled the OSS drivers… and now I have them installed, and I even seem to be using them (
chrome://gpu reports that I am, and I can move things around the screen).
But everything is screwed up – I can't get Unity to launch, I'm still booting into the black screen, and I can't seem to fix this.
edit: I removed
fglrx completely, and I now boot into a UI, but it's just a desktop background. No Unity.
edit2: I can now launch Unity manually… but it doesn't have any of my old settings, and doesn't have any plugins etc. So that's still not working great.
edit3: I went into CCSM and reenabled all of the plugins like Unity and gave default settings. IDK what else but something broke Unity, I can no longer launch it.
