lubuntu 12.04 slow glxgears

Asked by Russell D Mileham

Running lubuntu 12.04 on an old AMD Athlon XP Machine, and glxgears reports 15 frames per second. Hrdinfo gives this report for Display:

-Display-
Resolution : 1280x1024 pixels

-OpenGL-
Vendor : VMware, Inc.
Renderer : Gallium 0.4 on softpipe
Version : 3.0 Mesa 8.0.2
Direct Rendering : Yes

I think this indicates the software rendering is being used.

Using Lucid Puppy on the same machine, I noticed that the OpenGL section listed the following:

Vendor S3 Graphics Inc
Renderer Mesa DRI ProSavageDDR 20061110
Version 1.2 Mesa 7.7.1
Direct Rendering Yes

With this configuration, glxgears reports 350 frames per second.

Can I change the OpenGL Renderer in Lubuntu, and if so how?

Thanks

I'd say that's worth a bug report and perhaps interesting for developers.
Not sure if it's a good idea to downgrade mesa, Unity is a pretty different DE.

Sorry, Lubuntu doesn't have Unity as standard of course. Anyway, downgrading mesa may still conflict with dependencies.

Sam, thanks for the reply. I've not submitted a bug report before, but I am assuming there are instructions on the Ubuntu site. I will give it a try.

Say I decided to take a chance and downgrade mesa, I would I do it?

Thanks again,

Russ

If you upgraded, make sure you are running the build 2 release of the correct driver.

https://launchpad.net/ubuntu/precise/i386/xserver-xorg-video-s3

I've been seeing a few problems (not S3) where if the old driver is no longer in the repositories a release upgrade may not pick up the new driver and update it. Since the build 2 release of the S3 driver came out after 11.10 but before 12.04 you might want to check it before reporting the bug.

Thanks Chris,

I checked the package manager and build 2 is listed and installed. However, my video adapter uses xserver-xorg-video-savage.

By the time I got your reply I had already submitted the bug report. I just hope I did it correctly!

Thanks again,
Russ

Yeah it looks OK, I think. You might want to add that the driver in use is xserver-xorg-video-savage. It might not matter, but you never know...
