First, make sure xserver-xorg-video-savage package is installed. If it already is, please run this command to gather xorg info:
apport-collect 994878

You can try to force use of the savage driver by creating an /etc/X11/xorg.conf file with the following contents:

Section "Device"
        Identifier "Configured Video Device"
 Driver "savage"
EndSection

Section "Monitor"
        Identifier "Configured Monitor"
EndSection

Section "Screen"
        Identifier "Default Screen"
        Monitor "Configured Monitor"
        Device "Configured Video Device"
EndSection

Thanks for the reply Dave,

I ran apport-collect as you requested, I have also attached my config file (/usr/share/X11/xorg.conf.d/10-monitor.conf) and my latest xorg.log file. Let me know if I can do anything else.

Best Regards,
Russ Mileham

There is no more DRI1 support in mesa (from version 8.x which is in Ubuntu 12.04). That means these old cards for which there are no DRI2 drivers will not have hardware accelerated OpenGL. Unless you install DRI1 drivers yourself... See http://phoronix.com/forums/showthread.php?70813-DRI1-drivers-for-Ubuntu-12-04-(savage-mga-r128-tdfx-sis-unichrome)

Tormod,

Thank you so much. Your solution is exactly what I needed. Glxgears now reports 380 fps. Certainly not a speed demon, but sufficient for what I am doing.

Is there something I need to do to close this bug, or mark it as solved?

Best Regards,
Russ Mileham

It is an upstream regression, although a calculated one. A fix for Ubuntu would be to have these DRI1 drivers available in the standard repos (universe if that still exists?).

Changed in mesa (Ubuntu):
status: New → Confirmed
summary: - glxgears very slow
+ glxgears very slow (no DRI1 drivers anymore)

@Tormod, thanks for doing the packaging work on this.

Yes, I think it'd be fine for you to post your package to universe. I believe new packages need to go through a review process, but as this is split off from mesa itself I think the review should be straightforward. Go ahead and upload to universe and let me know if you need any help.

As we aren't officially supporting savage in ubuntu's mesa now, I'll close out the task as wontfix and leave community support to the mesa-legacy package.
