Hello!

     I am experiencing a strange lockup about once or twice a day while running
X-windows (I am running the tvtwm window manager).  What happens is that 
intermittantly my screen will just *poof* and appear that it lost all
horizontal hold.  It doesn't flicker or anything but rather just freezes.
The screen has slanted stripes, which are rather wide, running down it.
Sometimes, more often than not, I can still telnet into my system so it's 
not dead (sometimes it is dead though).  I've tried killing the X-server
and miscellaneous other stuff, but only a reboot truely fixes the problem.
I'm running on a DEC 466D2LP (a 486/66) and have the S3 chip and a local bus.
I also have 24 megs ram and a 11meg swap partition on a 245 meg HD.  I'm
running the XS3-0.4.4 server.  I am very impressed with linux and will quite
willing live with this minor inconvenience but am hoping some of the gurus
out there will be able to help or point me in the right direction.  Please
assume I'm an idiot ;-)  and if the answer is in the FAQ somewhere then I
just proved it to you.  Any further information needed will be gladly provided.
