I confirm anonym's problems. I have an Acer aspire 1692WLmi, Pentium M740 with ATI X700 graphics. With the proprietary fglrx driver (version 8.25.18), hardware 3D is unavailable with -686 kernel (version 2.6.15-26.46) but works with -386 kernel. This can be verified by running glxinfo and checking the "direct rendering:" line.
However, I suspect this may be a different bug, and possibly not with the kernel but with the fglrx driver or the restricted kernel module it needs. -- cpu idle time in /proc/stat wrong https://launchpad.net/bugs/30557 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
