Y non-visible but allocated VRam gets invalidated by the driver too early and upon reactivation of the VRam by some application, the application get's the notification that the Vram is not available and it has to reallocate and render again. I found at least one other guy with a different chipset (Intel GMA945) who suffers from the same problem with that driver:There are other applications as well that seriously suffer like TexnicCenter, Opera. That's simply not acceptable. Switching tabs in Firefox 2.0.0.7 may last once in a while for 1 - 15 seconds. Performance in 2D: This driver sometimes sucks 100% of CPU time and slows down screen updates dramatically. This problem seems to be recognized already:2.

(I stop here, because I get OffTopic).Okay, both problems really, really prevent serious usage! If there is no magic registry key that I'm missing here, then intel really has to do something, since this chipset is not at the end of it's lifecycle!These are the solutions I can think of beginning with the one with the smallest implementation effort:Get you EDID reading correct in the Windows GMA driver (not the IEGD)! Both of my monitors supply correct EDID information, which I can read by means of MonInfoTiming recommendation #1. Java2D library have specific strategies two walk round that problem by caching.
No requirement for CRT/LVDS/CLONE keyboard switch).My 82855 using laptop has drivers that don't allow widescreen resolutions.The IEGD ones do, but there are more problems with them.

I also can't use the FN key to switch between laptop screen and externalLCD.Is there no way to add the working widescreen resolutions to the normal non IEGD driver?At that time I also tried IEGD v8 and had similar issues.
If you're geek you might play with reduced blanking / GTF blanking in Linux modelines. If're stuck with analog VGA on your laptop, I suggest buying a new laptop for this external display. Since analog VGA 1920 x 1200 is just blurry and causes eye cancer due to the analog cable not being able to transmit ~150 MHz appropriately. However I suggest digital DVI or HDMI output. If you reduce the colors depth to 16bit even fancy Compiz Fusion 3D desktop effects are possible with this old chipset.
