I’m seeing an annoying error on my Portege M400 running Vista. The thing is almost clear of beta drivers now, after numerous downloads from Toshiba, including the display driver. The graphics chipset is a Mobile Intel 945GM, and I have a production release driver dated 13th December 2006, version 126.96.36.1991, though I saw the same problem with earlier releases.
Specifically, from time to time the display blanks out and an error 4101 is logged. Sometimes I get this supposedly reassuring toast pop-up:
The warning message is:
Display driver igfx stopped responding and has successfully recovered
The error is worse than it sounds. The screen blanking is irritating, and sometimes causes the current application to crash (I’ve seen this with games). I’ve also seen it when working with multiple displays. Fortunately it only seems to occur with the display is being stressed in some way – I can work all day in Word and Excel, and not see the problem.
I’ve tried turning off Aero and it makes no difference.
A bug in Intel’s driver I suppose (I never get this on my Vista desktop), though it is not exclusive to Intel; this user reports the same problem with a GeForce 7900.
This is the kind of thing that spoils Vista right now. I think this OS will work much better six months from now.
