I can confirm this bug is still open and is a major issue. Dapper 686 smp, with all latest updates, freezes a few seconds after logon when using a Radeon 7000.
My spec: 2 * PIII 733 mhz processors (Coppermine) Intel OR840 Workstation m/b 768 ram Asus ATI Radeon 7000 Ubuntu: Dapper 6.06 01 686 smp kernel (fully updated) - The 386 kernel works. With the 686 smp kernel: - Disabling FB, AGPFastwrites and DRI does not work - The VESA driver works -- system freeze when using ati radeon 7000 with xorg "ati" driver https://launchpad.net/bugs/16873 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
