dpkg-reconfigure xserver-xorg
Tell it to use i810, and play with Bit Per Pixel depths. This old
Compaq of mine freaks out if I use greater than 16 bpp. At 16, it's
perfectly stable.
0000:00:00.0 Host bridge: Intel Corp. 82810E DC-133 GMCH \
[Graphics Memory Controller Hub] (rev 03)
0000:00:01.0 VGA compatible controller: Intel Corp. 82810E \
DC-133 CGC [Chipset Graphics Controller] (rev 03)
Only four Mb video RAM, but it works.
Section "Device"
Identifier "i810"
Driver "i810"
BusID "PCI:00:01:0"
VideoRam 4096
EndSection
Section "Monitor"
Identifier "CPQ:2e00"
HorizSync 30-57
VertRefresh 43-72
Option "DPMS"
EndSection
That's a Compaq 171FS 15" monitor.
