Description Mitch Fisher 2001-02-19 16:24:40 UTC
When running XFree86 on the Trident Cyber9397, only the 800x600 mode works
correctly.  WHen running 1024x768 only about 1" of the righmost part of the
screen is displayed - the remainder is completely black.

This has been run from a Gateway Solo 9100 (Laptop) with a 4mg Trident PCI
adapter.  Video worked correctly with RedHat 6.2.

We (Red Hat) should really try to resolve this before next release.

Comment 2 Mike A. Harris 2001-02-25 14:20:32 UTC
Attach your X server logs, and you XF86config files please.

Comment 3 Mike A. Harris 2001-03-19 04:23:17 UTC
I am still awaiting your information.  You can attach the server log and
XF86Config-4 files using the link below.  Without these files and without the
hardware to test on it will be impossible to look into this any further.

Comment 4 Mitch Fisher 2001-03-22 05:53:44 UTC
I no longer have the RedHat XF86Config file.  However, this problem is identical
on other distrobutions as well.  This is not a RedHat problem but an XFree86 4.x

Comment 5 Shane Dunlea 2001-05-06 16:43:03 UTC
I had the same problem with an NEC Ready 440T Laptop (with the same video 
card). The problem was overcome by forcing X to use the XF86_SVGA server by 
creating the script /etc/X11/xinit/xserverrc:

  exec XF86_SVGA

which is read by default when starting X. I had to setuid root on XF86_SVGA. 
The xinit man page advised against this for security reasons and said that 
Xwrapper should be used instead to avoid this. Running Xwrapper caused the same 
problem (X is a symlink to xwrapper) and I couldn't find any config files for 
Xwrapper, so this was the best solution I could find. I don't understand why 
this works: I'm pretty sure my previous setup used XF86_SVGA anyway (but 
perhaps indirectly?)

Comment 6 Mike A. Harris 2001-05-07 10:22:45 UTC
The proper way to use XFree86 3.3.6 is not to edit any scripts but
to use "Xconfigurator --preferxf3".  I would strongly recommend reinstalling
all XFree86 packages prior to doing this however if you've edited the
files.  Others have commented that 3.3.6 works for them so I am closing
this bug.  Realistically we can't fix the bug in 4.x until XFree86 fixes
it in the base release.
