I can confirm this on my system, using an S3 Inc. 86C380 [ProSavageDDR K4M266] (rev 02), which according to Xorg.0.log is a "Twister PN133", Chip: id 8d01.
After asking at the xorg mailing list, they directed me to the bug Marcelo Shima was pointing out on his last comment. I can also run glxinfo, but executing glxgears results in a black window and 100% CPU usage. So basically, it seems that the DRI locking was broken in the driver, and that that has now been fixed upstream using the following patch: https://bugs.freedesktop.org/attachment.cgi?id=7041 (see the bug report for more information) ** Also affects: linux-source-2.6.17 (Ubuntu) Importance: Untriaged Status: Unconfirmed -- after recent update 3d acceleration with savage does not work https://launchpad.net/bugs/46314 -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
