Bug Description
When an X session is started for a second user, hardware OpenGL graphics acceleration is disabled for that user. The difference in performance is very obvious when using e.g. glxgears of planet penguin racer. This problem has occurred using both gdm and kdm. I can't swear that it happens every time, but I can't remember it not happening.
Perhaps a configuration file only allows acceleration on display 0 but not on display 1?
I'm using feisty.

Thank you for reporting. Please post the output of the command 'glxinfo' run in X-terminals in both X sessions [ separately as two files ].
