Ok, here is my dmesg. In fact, I think I have the same problem as here : #57716
I'll try to add the following to my xorg.conf as advised and see if it works: Section "ServerFlags" Option "AIGLX" "off" EndSection Section "Extensions" Option "Composite" "0" EndSection ** Attachment added: "dmesg" http://librarian.launchpad.net/4701483/dmesg -- no dri cannot init AGP in 2.6.17-10 AMD64 https://launchpad.net/bugs/62547 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
