X200 (X30x?) screen garbage - SOLVED
Posted: Tue Dec 29, 2009 3:09 am
As I suffered from the known X200 (X30x?) screen garbage problem in Win 7, and was pulling my hair out.
The problem every time after re-docking and waking up from sleep or hibernate, sometimes also even just when waking up outside dock.
Here I am posting the solution once for all:
As of today, the problem is with the newest Intel drivers (I think they are also available via Windows Update); I mean driver version 8.15.10.1968.
The solution is to remove this driver completely and force reinstall of older drivers (version 8.15.10.1855) from Lenovo site. After install, your monitor will be washed out - default gamma setting is messed. Open the Intel Graphics Accelerator Driver for Mobile Tray Program and reset the gamma setting to default (I think 2.0).
Since then, the garbage never appears again, and also problems with Win 7 BSOD after the screen being switched off in power-saving modes.
Hope this helps. X200 (particularly my X200t) are such nice machines and shouldn't be plagues with such stupid problems.
