Description Henry McBride 2001-03-07 13:49:45 EST
From Bugzilla Helper:
User-Agent: Mozilla/4.0 (compatible; MSIE 5.5; Windows NT 5.0)

The display appears grey and you can see a grey box for the cursor and no 
text at all. This is unlike Redhat 7 which this same setup works fine.

Reproducible: Always
Steps to Reproduce:
1.select the SIS 6326 video card
2.Select Impression 7 monitor
3.run test xconfig

Actual Results:  The test screen had a background but the cursor was a 
grey box and so was the message screen. No text was visible

Expected Results:  you should have seen the actual screen and a message 
asking you if you like the screen settings

Tested using the latest internel tree, using a GUI installation.

The card appeared to work well by default in that case,  X and gdm started in
runlevel 5 post-installation, without any video corruption.  No video corruption
while running X for 5-10 minutes and running arbitrary GUI applications in X.

changed to runlevel 3 after that test, and encountered problems running
Xconfigurator... All resolutions at 24bpp would either not start (with text
complaint that there is a problem with the X configuration, and back / quit
buttons), or X would start with the video corruption mentioned above.

Will give specific details after more testing, please let me know if there is
specific data needed.

Xconfigurator (with no options) result in good configurations at the following
resolutions and color depths:

8bpp: 1024x768, 800x600
16bpp: 1024x768, 800x600

some resolutions appear without substantial corruption, but clip the edge of the
screen (as if the virtual resolution doesn't match the display).  These are
basically useable, maybe xvidtune can get them better.  Could that be blamed
easily on the monitor?:
8bpp: 1280x1024, 1152x864, 1400x1050
16bpp: 1280x1024, 1152x864, 640x480

the following can't be tested (Xconfigurator gives up, telling the user that
there is a problem with the X configuration, and prompting with back / quit
8bpp: 1600x1200, 640x480
16bpp: 1600x1200, 1400x1050
24bpp: 1024x768

In 24bpp, 800x600 and 640x480 display, with severe video corruption (display
completely unusable).  testing 1152x864 at 24bpp results in a display of 640x480
at 16bpp.

I don't see any failures in your server log.  Can you reproduce the problem and
send me the log from that, and also your XF86Config-4 file, both as attachments.

Defered waiting for more detailed information.

Comment 10 Jerry Rabe 2001-05-18 15:23:25 EDT
I also have problems with my 8 MByte SIS 6326 card.  The RedHat installer
finds the card OK, but thinks it only has 4 MBytes of memory.  I have tried
every combination of 4MByte, 8MByte, 8/16/24 bit color, and every resolution
from 1024x768 on up.  The only combinations that displays properly is 1024x768
at 8/16 bits (either 4MByte or 8MByte).  Higher resolutions produce artifacts
and/or a wrapped screen image where you see the desktop icons on the right
side of the screen as well as the left side.  Testing 24 bit color does not
even display these artifacts, only a black screen until the timeout.

Windows has no problem with this card even up to 1600x1200 resolution.
Comment 11 Mike A. Harris 2001-06-01 18:45:26 EDT
Original bug reporter has indicated via email that enabling the "noaccel" option
in the config file has solved this problem for him.
