[PD] [Gem]: "Failed to map depth buffer"

[Roman Haefeli]

it would already be helpful to know, if someone on ubuntu dapper with
fglrx-driver is able to use gem and which version of gem. if yes, could
this someone post me his/her xorg.conf-file? (just in case it is a
matter of wrong settings)

thanks in advance
roman
