[ubuntu] Toshiba Laptop glitches

view story

http://ubuntuforums.org – So here's the deal: I've been playing with my Toshiba L775D-S7107 (Satellite L775) and I'm able to boot the Live system from a USB flash drive fine and dandy. Everything works. I just installed it to the hard drive and now there are problems. The boot screen doesn't show up, no biggie. Sometimes the login window shows up but the built-in keyboard & trackpad lock up. Some times the login screen won't show up but the keyboard seems to still work, seeing as I can login (type password, press enter, login sound plays.) I can't seem to use Alt+F3 to switch to a text screen. Any suggestio (Hardware)
