XFree86 on Laptop Question

XFree86 on Laptop Question

Post by Zane A » Thu, 01 Oct 1998 04:00:00



        Hi, I'm running RH 5.1 on my Toshiba Protoge650CT, and (not
suprisingly it seems) am having some trouble getting XFree86 to work...
The video chipset is C&T 65550 (don't even know if this really matters),
resolution 800x600, active matrix screen.  I have the resolution and the
mouse working fine, but I think there is something horribly wrong with my
synch rates.  When I start up X, I get all these flashing horizontal black
lines, and the screen kind of flickers.  It's usable, but just barely.
Does anyone have any info on setting the synch rates for an LCD monitor?
I'm running the XF86_SVGA server, and have the hsynch set to 31.5-35.1kHz

in the menus in xf86config).  I don't really know which parts of the
XF86Config file to edit to change the synch rates... and don't want to
damage the display (of course) any help would be greatly appriciated.
Thanks!  Zane AE

You need to run xf86config, there is an option for custom
rates.  Get some documentation, on the supported sync
rates, for your system.

Please note that Xconfigurator, does not seem to support
custom modes always.  To start xf86config, simply type
xf86config.
