I'm trying to get working the Poulbo driver under Ubuntu 9.10. I've installed poulsbo-driver-2d poulsbo-driver-3d poulsbo-config packages from sudo add-apt-repository ppa:gma500/ppa. The packages installation is working. After I have to put in xorg.conf driver "psb". Then I reboot and I have no more display. I have to switch back to vesa in order to display back. Can someone give me some kind of solution?
