I already deleted my PAE kernel, therefore I reinstalled the removed packages: apt-get install linux-generic-pae linux-image-2.6.38-8-generic-pae linux-image-generic-pae
These are the interesting lines: run-parts: executing /etc/kernel/postinst.d/dkms 2.6.38-8-generic-pae /boot/vmlinuz-2.6.38-8-generic-pae * dkms: running auto installation service for kernel 2.6.38-8-generic-pae * fglrx (8.840)... [fail] dkms: WARNING: linux headers are missing, which may explain the above failures. please install the linux-headers-2.6.38-8-generic-pae package to fix this. The dkms build failed, too: dkms build -m fglrx -v 8.840 -k 2.6.38-8-generic-pae Error! Your kernel headers for kernel 2.6.38-8-generic-pae cannot be found at /lib/modules/2.6.38-8-generic-pae/build or /lib/modules/2.6.38-8-generic-pae/source. You can use the --kernelsourcedir option to tell DKMS where it's located, or you could install the linux-headers-2.6.38-8-generic-pae package. Then I added the PAE headers...: apt-get install linux-headers-2.6.38-8-generic-pae ... which built and installed the missing driver automatically: ... run-parts: executing /etc/kernel/header_postinst.d/dkms 2.6.38-8-generic-pae /boot/vmlinuz-2.6.38-8-generic-pae * dkms: running auto installation service for kernel 2.6.38-8-generic-pae * fglrx (8.840)... [ OK ] run-parts: executing /etc/kernel/header_postinst.d/nvidia-common 2.6.38-8-generic-pae /boot/vmlinuz-2.6.38-8-generic-pae Booting into the new PAE was flawless. The missing package (linux-headers-2.6.38-8-generic-pae) was not present when I updated to 11.04. Therefore I suggest that this package is added when a PAE kernel is set to be installed with drivers like fglrx. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to fglrx-installer in Ubuntu. https://bugs.launchpad.net/bugs/747729 Title: fglrx crashes X server on startup _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
