Corrupted screen and degraded performance on Savage/IX-MV

[Luca Aluffi]

Binary package hint: xserver-xorg-video-savage

Hi!
Just decided to give a try to Ubuntu 10.04 on this Omnibook X3 laptop, and following is what happens.

The login screen is corrupted, but if I enter the password it resets to something tartan-like look. After a little while the magic happens and the desktop appears. This after the last update of lucid lynx; until last week everything was a burden, and I was used to switch to console mode with network in order to gain new updates.

If I try with GLXINFO or GLXGEARS I get an error and, generally speaking, screen is a little slow.

Just to say, everything is fine with ubuntu 9.04 and, if I run "dhry2" benchmark, results between 9.04 and 10.04 kernel are almost identical.

I'll attach logs. The error given by glxinfo is

luca@ubuntu:~$ glxinfo > glxinfo.txt
glxinfo: ../common/drirenderbuffer.c:69: driNewRenderbuffer: Assertion `format == 0x1908 || format == 0x8050 || format == 0x8058 || format == 0x81A5 || format == 0x81A6 || format == 0x81A7 || format == 0x8D48' failed.
Aborted (core dump creato)

Let me know how I can help. If needed I can also take some shots of the login screen with my camera.

Ciao
Luca

I can confirm the these issues on a Savage Twister card, trying out a fresh installation of the Lucid alpha-3 candidate. First login screen was a small box in the middle which did not show the whole "screen", after logging in I was thrown back to login screen which now was fine. I also got the same assertion dump in the log. Only after making an xorg.conf with NoDRI I was able to login successfully.

The assertion was reported in bug 515846 so I will mark this as a duplicate for now. If there are additional issues on savage, we can reopen this report once that is cleared out.

Hi!

While the problem with mesa-utils has been succesfully fixed, this one is still going on.
How can I help?

After last updates gdm the situation is going fairly better: gdm looks good and user interface is behaving well.
It remains just the splash, which is in text-only mode, but it's the least important thing.

Have a nice weekend

Just an update: video playback performance with totem is risible now. Everything goes smooth with vlc.
