Description Michael LeMay 2008-01-24 17:59:24 EST
Description of problem:
When using the sis x.org driver with a SiS 662 integrated graphics card on an
Intel D201GLY2 motherboard, vertical lines with quickly varying horizontal lines
extending out from them appear on the screen at all times.  By using a custom
"premium" driver, as described in the last post on the following page, the issue
is resolved: http://ubuntuforums.org/showthread.php?t=463077&page=8  The lines
also disappear when the VESA driver is used, but that is far too slow.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Install and use xorg-x11-drv-sis
Actual results:
Vertical lines through screen

Expected results:
No vertical lines through screen

Reporter, I am sorry but I have a bad news for you. According to
http://www.winischhofer.eu/linuxsispart4.shtml#download, Thomas Winischhofer
"[t]he premium version. This version is only available in binary form and for a
fee. It has advanced features not available in the Free Version.", so I don't
think we can carry it. Do I understand correctly that somebody ripped out a
binary driver out of the Thomas' distribution for-fee tarball?

Reporter, could you please reply to the previous question? If you won't reply in
one month, I will have to close this bug as INSUFFICIENT_DATA. Thank you.
Comment 3 Michael LeMay 2008-02-25 18:26:17 EST
I apologize, I missed the notification of the previous comment.  Yes, the driver
I was using was taken from a for-fee tarball.  I was hoping that the redhat team
could port whatever techniques he's using in that distribution to the free,
default driver, since the non-free driver I'm using hasn't been supported in
quite awhile and is quite flaky (segfaults with certain xorg.conf
configurations, etc.).  Perhaps that violates RedHat's philosophy, however.  Thanks!

It’s not the question of philosophy, we just cannot read binary any better than
you can :-).

Closing as CANTFIX

The source is available for download here:

source driver, but it comes from the same author and I have no experience with
