Bug Description

When I log in to a guest account, or any other account other than the main, graphics is really slow and choppy. Works as it should on the main account.

Hi martin-wetterstedt,

Please attach the output of `lspci -vvnn`, and attach your /var/log/Xorg.0.log (and maybe Xorg.0.log.old) file from after reproducing this issue. If you've made any customizations to your /etc/X11/xorg.conf please attach that as well.

Only the first (out of several simultanous) X sessions get DRI (and hardware 3D acceleration). This is a limitation on the current X stack. Wait for kernel mode-setting for radeon cards.

KMS is now enabled by default in lucid, so presumably this issue is solved now.

Note that there are some general performance regressions with kms but that's covered under other bug reports.
