Description Jason Costomiris 1999-10-10 04:14:35 UTC
The Tecra 730CDT uses the C&T 65550 chipset for the
display.  Under Windoze, this display does 1024x768x16bpp,
however, under RH6.1, using Xconfigurator, I was only able
to get 1024x768x8bpp, most hideous, IMHO.

I went into the XF86Config, dumped all of the extraneous
Modelines, changed the Screen sections to use the proper
color depth, and put in a single Modeline that works great:

ModeLine "1024x768" 46.0 1024 1032 1176 1344 768 771 777 806

I also reset the HorizSync to 25-64 and the VertRefresh to
40-70.  It's working great now!

Cartman looks great so far.  You guys might want to include
this fix in the next update of Xconfigurator...

I think the problem is that if you specify 16 bpp and 8 bpp, the 8 bpp is
default. Fix is to add DefaultColorDepth 16 to this section in XF86Config or
start with --bpp 16.
