I'm working on Toshiba Satellite L20-183 laptop with Ati Xpress 200M. I'm also using logitech optical wired mouse. I've installed Ubuntu. And everything was ok. Then I've installed fglrx drivers in that way:
sudo apt-get install xorg-driver-fglrx fglrx-control
and just changed vesa to fglrx
After that i have big problem with my mouse. After login to ubuntu its working fine, but after some time mouse died. But not only mouse. I think that all usb is dead. Also I can't switch between terminals by pressing [alt]+[ctrl]+[Fx]. I can't restart x server ([ctrl]+[alt]+[<-]) and i cant turn my computer off normally. I must turn the power off. I can use my touchpad to move cursor.
I was trying to unplug it and plug it again. Nothing happened.
I wad trying other mouse. The same effect.
Whats more this problem was when I was using 5.10 and other released of 6.06 and when i was using other methods of installing fglrx.
I hope that you will look at this problem because it last at least for month and I can't use my ubuntu :(
