Comment 32 for bug 133192

My symptoms: on my notebook (Dell Inspiron 8600 w/ ATI Mobile Radeon RV350 (M10)), the new driver causes the LCD to be blank, with odd-colored vertical lines appearing somewhat randomly, and the entire screen fading very slowly to white).

Reverting back to xserver-xorg-video-ati_6.6.3-2ubuntu6_i386.deb works 100%.

Disabling ColorTiling, GLX, and DRI did not help anything.
