12.04.4 Breaks Things/Video Left and Right
I recently updated my LTS Ubuntu automatically, to 12.04.4 I believe. This broke things.
After the update:
-Shutdown is much slower
-Shutdown sometimes fails
-The app launcher (or whatever that top left thing is called) crashes from time to time, leaving the system useless. When this happens, the system often gets confused about restart and reboot buttons, and switches their functions (if they work at all)
-Stellarium stopped working completely (installed from repo)
-MPlayer fullscreen stopped working (also repo)
My motherboard/graphics is ASUS M4A88TD-V EVO/USB3, with integrated ATI Radeon HD 4250 GPU.
If someone can tell me how to start sorting this out I'll be very grateful. Thank you in advance!
