quoth Shawn Tayler:

| but if I set for DefaultDepth of 16 I get 640x480 res.  Is there a
| way to force 1024x768 with the 16bit depth?

that depends on just how willing you are to break things and your 
familiarity with tools for unbreaking them. first thing, back up 
your /etc/X11/XF86Config; if you have a distribution that puts it 
someplace else, replace your distribution. i'd recommend copying it 
to /etc/X11/XF86Config.works for ease in copying it back if you break 
the one you're working on.

i presume that you have and are familiar with a proper console text 
editor. the one that comes up under f4 in mc is perfectly adequate.

now. in XF86Config set the default depth to 16:

  DefaultDepth 16

and remove all resolutions except 1024x768 from the resolutions line for 
that depth:

 SubSection "Display"
    Depth      16
    Modes      "1024x768" 
  EndSubSection

again, have you set the memory in XF86Config? also, the memory issue is 
of interest, of course. from the link i sent you a little while ago:

"By default 8 Megabytes of system memory are used for graphics. For the 
830M and later, the default is 8 Megabytes when DRI is not enabled and 
32 Megabytes with DRI is enabled. This amount may be changed with the 
VideoRam entry in the config file Device section. It may be set to any 
reasonable value up to 64MB for older chipsets or 128MB for newer 
chipets. It is advisable to check the XFree86 log file to check if any 
features have been disabled because of insufficient video memory. In 
particular, DRI support or tiling mode may be disabled with 
insufficient video memory. Either of these being disabled will reduce 
performance for 3D applications. Note however, that increasing this 
value too much will reduce the amount of system memory available for 
other applications."
