parisc-linux@lists.parisc-linux.org is normally a good starting point.
I've cc'd the list in case someone else has better ideas.

The 712's have been working quite awhile and it's just further
back in the mail archives! ;^)

You might also look at ftp://ftp.parisc-linux.org/kernels/712/
and try out the XF86Config files there.

Basically, you need a kernel with STI framebuffer support and configure
XFree to use the fremebuffer driver. Mouse and keyboard are standard
PS/2 components so there's no problem, too. If your colors are totally
wrong, place 'Visual "TrueColor"' into the "Display" subsection of your
"Screen" section. Pay attention to your screen resolution and color
depth - they have to exactly match to what you get on boot-up since
there's no support to switch to another resolution/depth right now IIRC.

Does this mean that's there is no way to run with a 24 bit depth
on a Vis-EG?  I have been playing with this but I haven't had any luck.
There doesn't seem to be any way to change the depth from 8 bpp on a
c3k using the PDC (there is user defined parameter set but it's not
clear how it can be set other than possibly with sam under hpux).  I
tried "stifb=bpp32:" but this didn't have any effect on the reported
1280x1024-8 config in dmesg:

STI GSC/PCI graphics driver version 0.9

The linux config has

CONFIG_FBCON_CFB8=y
CONFIG_FBCON_CFB32=y
CONFIG_FBCON_STI=y

Oh, I've one other X config problem.  The usb mouse stops responding
at logout from kde.  If I restart the X server with <alt>E, functionality
is restored.  I don't believe that this is a kde problem.  Anybody have
a solution?

that's correct. Vis-EG only supports 8-bit color.
We could get 24-bit color if we could get FX-E cards working but
they suffer the same lack of support as FX-[246] cards.

I've switched to using "TrueColor" until Xf86 "render" module
stops hogging most of the colormap. Regular text modes are fine.
Image quality does suffer though.

BTW, Vis-EG on C3k does support 1600x1200 if you multi-sync monitor
can handle it. Most LCD displays can not.

This is an old problem. First mention of it was several years ago.
More recently (Sept 2002) there's a whole thread on it starting with:
    http://lists.parisc-linux.org/pipermail/parisc-linux/2002-September/017724.html

Work around is to switch to VT1 (ctl-alt-F1) and then back to the
FB VT (ctl-alt-F2 in my case).
