If I was you I would remove the references for your 640x480 screen mode
for X as it's pointless so that X automatically defaults to 800x600.  If
you still need 640x480 make it the second mode definition so that X
default to 800x600.  Then re-enable your screen expansion and reboot.  See
what that does.  With screen expansion I hope you have found a nice text
console screen size to use so that when the text is expanded it looks
okay.  This involves a kernel recompile and various things.  If you need
to know how to do this just ask and I will guide you through this.

This is probably do to some of the X server acceleration functions being
activated that then play havac with your machine due to X not knowing
about suspend and hibernate.

Add to you XF86Config file under the graphics card section

Option "noaccel"

and see what that does.  There are quite a few acceleration options
avaliable for the trident cards (see trident.txt or something
similar) that you can play with to try and get more speed or
compatibility from X.  However usually these can be direct trade-offs and
only a trial and error approach method can find whats good and whats not.

I was only able to get sometihng like this on a desktop machine by
plugging the floppy drive in the wrong way round ;)

When I upgraded to X 4.0.0 some time ago I did a straight binary write
over.  This caused me no problems.  However instead of xdm I use Login.app
as it provides a much nicer login screen :)

Just type

apt-get install Login.app

and see if that helps if you have apt-get setup.  If you don't just find
the relevent Login.app deb packages and manually install them.

If this doesn't work a possibility is that xdm (or Login.app) is not being
run as root and so you may be able to change this by editing
/etc/inittab.  However I'm not sure.

these if I remember can be found in some other tarball from
www.xfree86.org or its relevent mirror sites.

???  The only useful configuration files for X windows for me has been
XF86Config and .xsession.  I never actually was able to get xserverrc to
do anything constructive, however this could just be me :)

try Login.app much nicer ;)

good luck
