[ubuntu] Text/fonts display garbled after hibernation resume

view story

http://ubuntuforums.org – I have just installed ubuntu 12.04 LTS as a primary ex4 partition (as a sole OS) and set the swap partition over double my RAM which was 3 GB (Swap partition is currently 10 GB). The thing that I just experienced is having the fonts and texts just garbled after resuming hibernation, I was wondering if there is an incompatibility with my graphic card driver or something else ? ---> This is the Snapshot of the current OS view Thanks for your time, Amir (Hardware)
