[ubuntu] Text on black background and transparency issues after updates installed

view story

http://ubuntuforums.org – Hello. Yesterday before leaving work I did some updates on my ubuntu (the update manager popped out, I clicked Install and off it went). After it finished the system asked for a reboot, but I just turned it off, since I was leaving the office. When I came back today all hell broke loose. 1) Most text displayed anywhere has a black background (most of it was gray or black, so now it's unreadable). 2) Some letters are missing in popups. 3) Transparency effects are going wild. 4) ALL text in Firefox (on websites) is black (if it's not on a black background), totally ignoring all CSS and lo (Hardware)
