Comment 45 for bug 274290

When I tried to update the original 8.04.2 to 8.10 I still experienced a problem with X -
the resolution is detected fine, but the screen goes blank if you move the mouse or hit a button.
If I changed console to F1....F6 and returned to X after that I was able to see the screen for the instant of a second.
After that it goes blank again.
In contrast to the behaviour before the tft-display doesn't go into energy saving mode but stays blank.

Since I continued updating to 9.04 I'm up'n'running right now, but the proposed solution seems to only partly solve the problem.
