Re: Laptop Monitors

Try specifying chipset clgd5436 in place of 754x.  It worked
for me on a Gateway Solo2100 laptop with a 7548.  Here's my
XF86Config:

# This file is derived from Gordon Chaffe's

#
# This works for me with a Cirrus Logic 7548 on a Gateway
Solo 2100 Laptop
# with the XFree86 3.2 release running Debian/GNU Linux.  It
also works OK
# with XFree86 3.2A.  It only works with a setting of 1MB of
video memory.
# The 2MB setting is close, but not quite right.  Specifying
either of
# clgd5428 or clgd5436 seems to be alright.
