http://askubuntu.com – So I updated my computer a while ago... bad choice. Now my desktop is all screwed up. Without unity running it runs just fine... but unity controls everything so its hard to do anything without it. What it is doing is stretching the windows and for that matter anything other than the side bar and top bar. Its so stretched you really cant do anything. I do not know how to pull any information about this to provide to the community so if you show me the command ill do it. :) my computer is custom built. It has a amd 64 proccessor and a radeon 4650. I am on 12.05. Dont upgrade to 12.10 because it (HowTos)
