Gerhard Burger, thank you for reporting this and helping make Ubuntu better. Could you please provide the information following https://wiki.ubuntu.com/DebuggingKernelBoot ?
As well, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the kernel in the mainline kernels archive directory daily folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags: kernel-fixed-upstream kernel-fixed-upstream-VERSION-NUMBER where VERSION-NUMBER is the version number of the kernel you tested. For example: kernel-fixed-upstream-v3.7-rc1-quantal This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag: needs-upstream-testing If the mainline kernel does not fix this bug, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-VERSION-NUMBER As well, please remove the tag: needs-upstream-testing If you are unable to test the mainline kernel, please comment as to why specifically you were unable to test it and add the following tags: kernel-unable-to-test-upstream kernel-unable-to-test-upstream-VERSION-NUMBER Please let us know your results. Thank you for your understanding.

Quite regularly the graphics driver does not load on boot and I am stuck with a purple screen. Grub shows fine but when I select Ubuntu I get the purple screen. On a successful boot the purple screen disappears and I see the runscripts (I removed 'quiet splash' from the boot options'), but sometimes the screen merely flickers and stays purple.
