Works too on my old Dell C400 with a

VGA compatible controller: Intel Corporation 82830M/MG Integrated
Graphics Controller (rev 04)

Good thing is I have no issues on login screen but I'm using
/etc/X11/xorg.conf.d/20-intel.conf not /etc/X11/xorg.conf to store my
settings.
This configuration resolved (at least for me) a bug with
xserver-xorg-video-intel package too:
