Description cubexco 1998-12-14 05:59:42 UTC
The Xconfigurator as well as xf86config identify the video
chip as cirrus logic 542X. They show the different modes
available (8bpp, 16bpp & 24bpp) however when i try to run
startx in 16bpp, 640x480 mode, the server crashes, saying
this mode is not available. I have 1Mb video ram.

Comment 1 David Lawrence 1998-12-14 17:10:59 UTC
The Cirrus Logic driver requires additional options to be added the
the /etc/X11/XF86Config file to allow for 16bpp color and above. For
directions on how to do this please refer to
