This is what's happening (which is quoted below, too)

The Compaq iPaq workstations are using Intel 82815 graphics controllers.
>From Win2k, here are some specifics (which may or may not aid in
troubleshooting):

BUS:            0,2,0
MemRange:       44000000-47FFFFFF
MemRange:       40300000-4037FFFF
I/O Range:      03B0-03BB
I/O Range:      03B0-03BB
MemRange:       000A0000-000BFFFF


The Win2k driver specifics are as follows (for reference):
Driver Provider: Intel Corp.
Driver Date:     7/14/2000
Driver Version:  5.12.1.2636

(note that the Win2k info is for hardware reference, as the chipset
works fine in Win2k).

Monitors are all HP L1506 LCDs.


My lts.conf has the following options:

X_COLOR_DEPTH = 24

and I've tried the following (without any luck):

X_RAMPERC = 99
X_RAMPERC = 01
X_RAMPERC = 80


Any ideas, insight or help would be greatly appreciated. The labs can
function without X_RAMPERC in place, but the students use OpenOffice and
other apps (which apparently have this pixmap bug) and it's quite
frustrating for them and the teachers.

Thanks all!
