Comment 17 for bug 185440

I fell into this problem when upgrading from 6.06 to 8.04 on my Toshiba Satellite A25-S207 that has this Trident CyberBlade XPAi1 graphics chip.

It is always a great inconvenient when something stops working as it should in a upgrade. Found some forum posts describing the bug before 8.04 release.
