No 3d Acceleration for VIA VN896 Chrome9 IGP Graphic Card

[Simon]

Apologies if this is not the correct place to report this.

I am running a Laptop (Intel Core 2 Duo T2050 1.6GHZ, 1024MB RAM) with a VIA VN896 Chrome9 IGP Graphic Card and Ubuntu 7.04.

I have problems relating to graphics:

Firstly, I am unable to select 1280x800 screen resolution, so everything looks stretched.

Secondly, any games with more than just very basic graphics e.g. Assault Cube, Tremulous crashes the laptop (from a screen perspective).

Thank you for taking the time to report this bug and helping to make Ubuntu better. Unfortunately we can't fix it, because your description didn't include enough information.

Please include the information requested from [WWW] https://help.ubuntu.com/community/DebuggingXAutoconfiguration as separate attachments.

Here is the openchrome repo for vn896. It only supports 2D graphics so far. Will this driver be included in 7.10?

[Adam Niedling (krychek)]

And here is source of the official driver: http://www.viaarena.com/Driver/vt3336-3364xorg40079-kernel-src_20070611.tgz

Someone should be able to compile it..

Tell me if there's anything else you'll need. Se also related bug #133560 and bug #137474.

dpkg reconfigure-xorg wont detect these chipsets and uses the Vesa driver instead of a VIA one. Manually switching to the VIA driver doesn't seem to work either. The xorg configuration utitlity is also unable to detect the resolution for the screen. Desktop Effects in Gnome dont seem to work with this chipset either. This issue especially effects Fujitsu Notebooks, many or which have chrome9 graphics chips.

[Martin Doucha (next-ghost)]

You can set any resolution you like by opening ~/.tremulous/base/autogen.cfg in your favourite text editor and changing 3 lines (example for 1280x800):

seta r_customwidth "1280"
seta r_customheight "800"
seta r_mode "-1"

These lines are already present in your autogen.cfg but with different values in quotation marks.

Please test 7.10 or Hardy using xserver-xorg-video-openchrome package. You need to change the driver to "openchrome" on Hardy.

[Adam Niedling (krychek)]

7.10 live cd doesn't even start on my laptop, cuz x server can't start: https://bugs.launchpad.net/ubuntu/+bug/153944

However, the xserver-xorg-video-openchrome package is revision 357, even thou #491 is the latest one.
I won't use the openchrome driver until it supports 3D too, because the vesa driver is working fine now.

[Alexander Sutyrin (a-sutyrin-gmail)]

I've got a laptop with the same VIA VN896 video and Hardy installed.

me@rover:~$ sudo apt-get install xserver-xorg-video-openchrome
...
The following packages have unmet dependencies:
  xserver-xorg-video-openchrome: Depends: xserver-xorg-core (>= 1:1.1.1) but it is not going to be installed
E: Broken packages

Is this a reason to make another bugreport?

[Timo Aaltonen (tjaalton)]

That was due to a change that got dropped from that upload. There is a new one available that was just released to the archive.

Hi headflux,

Thank you for taking the time to report this bug and helping to make Ubuntu better. You reported this bug a while ago and there hasn't been any activity in it recently. We were wondering is this still an issue for you? Can you try with the latest development release of Ubuntu? (ISOs are available from cdimage.ubuntu.com)

If it remains an issue, could you also attach a new /var/log/Xorg.0.log?
Thanks in advance.

[Bryce Harrington (bryce)]

We're closing this bug since it is has been some time with no response from the original reporter. However, if the issue still exists please feel free to reopen with the requested information. Also, if you could, please test against the latest development version of Ubuntu, since this confirms the bug is one we may be able to pass upstream for help.

[Adam Niedling (krychek)]

You can check at linux.via.com.tw if there is a linux driver for this chipset. There is none. I don't see much reason for keeping this bug open anyway.

[Flávio Etrusco (etrusco)]

Adam, this bug is about the openchrome bug, not about the via one.
Bryce, as a matter of fact, in both Intrepid and Jaunty this chipset doesn't even work (it freezes) on the default installation; it's necessary to disable some acceleration options in xorg.conf. Other than that the 3D "acceleration" seems to work (although 120fps in glxgears isn't exactly fast ;-).

[Adam Niedling (krychek)]

According to the openchrome wiki page, 3D is not implemented yet for this chipset.
