This seems to be a "missunderstanding" between the driver and the graphic
chip.

Sometimes when my TP 765L wakes up from hibernation/suspend I also have a
display that looks like the LCD can't sync in X as well as in the text
console. To get back the display I have to do the following steps:

1. Switch to a text console
2. Press Fn+F3 (Screen goes blank, backlight is now off)
3. Press any key to resume

Now I have a restored text console. I can switch to the X display and
continue to work.

Btw., my TP 765L uses a Trident cyber9385. I didn't had this problem with
XFree86 3.3.x.
