I'm running Slackware 96 (kernel 2.0.0) and have recently upgraded by XFREE86 system from 3.1.2 (supplied) to 3.2, largely to improve my X Windows capability. My system has 32MB RAM and a 120MHZ Cirrus 6x86 chip, with a 1MB Cirrus Logic GD5434, and a standardish 14 SVGA monitor.
By running XF86Setup, I've been able to improve my situation from 640x480 (256 colours) to 800x600 (256 colours), but I can't get 64k colours, which I believe is possible (when I try my monitor seems to go bananas. Can send more details if required.
Help very gratefully received.

Have you been using the config tool that comes with SW96 to help setup your X?  I'm not sure what they call the latest version, but it may help to setup the 64K modes.  Failing that, you would need to send along some details about your monitor capabilities such as horiz and vertical frequency limitations so that an xconfig file could be knocked up.  The easiest way (usually) to get X working is to use someone's config utility - e.g. RedHat/Slackware/whoever - but failing that you can usually tweak the config file settings and get it to work - it just takes longer; and requires more coffee :-) Let me know what sort of monitor you have and I could knock up a config file for you.

If your monitor `goes bananas', it means you have set the scanrate too high.
Check that the HorizSync and VertRefresh lines in your /etc/XF86Config are correct (see monitor documentation). Try lowering the maximum value.
Also, changing to a lower resolution might help.
