Comment 0 for bug 631880

I have a TouchSmart tm2 2000el with an i3 and a HD5450. I had to install Ubuntu on a USB pen drive (16GB). I chose the 64 bit version. I installed the proprietary driver of the ATI HD5450 and it said me to restart the system. After the restart, even when I try the rescue mode I cannot load properly Ubuntu because the screen is black, not even illuminated, totally powered off. When I press ctrl+alt+del I see the normal Ubuntu loading splash screen and then the system restart.

The Ubuntu version is the 10.04 x86_64 without any update done.
