No (visible) 3D rendering with sis_dri.so on SiS630

[Torsten Rausche]

If xlibmesa-dri package is installed I don't get 3D graphics output in
applications using Mesa (e.g. glxgears) on my laptop system with SiS630 chipset.
There are no error messages on stdout, stderr, syslog or Xorg.0.log. The output
of "glxgears -info" shows that hardware rendering is used and that frames are
being rendered but the output window remains black.
I forced software rendering by renaming sis_dri.so and restarting X. After that
"glxgears -info" tells that software rendering is used and the output window
shows the expected rotating gears albeit with some graphical glitches.
I am using a daily updated Hoary installation with xserver-xorg. The xorg.conf
is setup according to http://www.winischhofer.at/linuxsisvga.shtml and
Xorg.0.log tells that SiS driver, DRM, DRI etc. were initiallized successfully
shows no errors.

Occurs always.

Steps to reproduce:
1) Use system with SiS630 internal graphics engine.
2) Install Ubuntu Hoary with x-window-system-core (includes xserver-xorg,
xlibmesa-dri etc.) and kernel 2.6
3) Use x-server with "sis" driver
3) Start x-server and start "glxgears -info"

Actual results:
Window remains black, no 3D objects are being rendered

Expected results:
Window should show 3D rotating gears

linux-image-2.6.10-2-686 2.6.10-14
xserver-xorg 6.8.1-1ubuntu15

I've taken this up with Dave Airlie upstream, thanks.

I have the same problem with hoary 5.04 stable

[Mgarridoe-phreaker (mgarridoe-phreaker)]

I've installed an own-compiled kernel from debian 2.6.8 sources with sis_agp
included (not as module) and without the problematic -
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=%23268169 - vesafb module (in
kubuntu loads as module from initrd and there is not an easy way to get ride of
it) and rendering works.

I'm going to compile one with the same .config with sources from ubuntu.

[Mgarridoe-phreaker (mgarridoe-phreaker)]

Finished compiling kernel-image-2.6.10 with ubuntu linux-source-2.6.10 and the
rendering did not work.

Switching back to own-compiled kernel-image-2.6.8 with debian sources.

It's not as good as I was thinking, tuxracer, gl-117 (at least) shows no
textures, other games work

Hello,

I have the same problem with a SiS630 card on breezy. Refering to
http://www.winischhofer.at/linuxsisvga.shtml all binary and module are shiped
with ubuntu. The first problem is that the fb is not set to 1024x768x16 as i
wrote on the menu.lst : # nonaltoptions=quiet splash
video=sisfb:versa:792,mem:12288 . I don't know why. If i load sisfb from
/etc/modules, i got the correct screen resolution and /dev/fb0 correctly created.

I read /var/log/dmesg and all seems to be fine. The /dev/fb0 device is not
created. I read the Xorg.0.log and i see this interressant lines :

(EE) SIS(0): [dri]SISDRIScreenIni failed because of a version mismatch.
        [dri] libdri version is 4.1.0 but version 4.4.x is needed.
        [dri] Disabling DRI.

dpkg -S /usr/X11R6/lib/modules/extensions/libdri.a give xorg.org which is at
version 6.8.2-23 (breezy).

I don't know how to have the correct version of libdri (is this a problem of
Xorg, Xfree86 backport on Xorg, ???)

Thanks.

Apparently Thomas Winischhofer, maintainer of the SiS X driver, has fixed this
by adding one line of code to the SiS DRI sources.

http://www.winischhofer.at/linuxsispart3.shtml#chglog
<cite>
UPDATE (05/06/26) For once, DRI-related: Found the problem with DRI and linux >=
2.6.9. Patch submitted to the MESA people. A patched SiS DRI driver is in the
download secion (see section 8).

<cite>
8. DRI driver for X.org 6.8.2

Beginning from Linux kernel 2.6.9, DRI stopped working. Usually, folks only got
a black screen. The binary below fixes this problem. The corresponding patch is
already checked into the MESA CVS (see here [1])

    * sis_dri.so [2] for X.org 6.8.2 (x86; compiled with gcc 3.3.6)

[1]
http://cvs.freedesktop.org/mesa/Mesa/src/mesa/drivers/dri/sis/sis_screen.c?r1=1.11.2.1&r2=1.11.2.2
[2] http://www.winischhofer.net/sis/sis_dri.so_6.8.2.tar.gz
</cite>

I simply replaced my /usr/X11R6/lib/modules/dri/sis_dri.so with the one from
above URL and it works!

we have this fix in mesa now
