Kernel 2.6.31-1 arrives; breaks X
The kernel 2.6.31-1 was on the list of upgrades in Ubuntu’s upcoming Karmic Koala release. The Koala is still in its Alpha 2 stage and almost all the other things usually go pretty well. However a kernel upgrade is always brings with it some uncertainty, some unexpected behaviour.
While 2.6.31-1 marks a bigger shift in kernel structure from 2.6.30-10, the older one seemed to have started working correctly after having brought about the first Green Screen of Death while booting with Ubuntu Linux. There were a few kernel upgrades to the older one which overcame the issues, I guess in grub.

Today’s upgrade to 2.6.31-1 was able to go past the grub stage and when the loading was complete, the display failed to load X. There was also some nvidia drivier update which might have destabilized the X, but apparently the X seems to be working correctly when I choose the older kernel at grub. So there must be some sort of a compatibility issue with the new nvidia update and the latest kernel.
This being the Alpha release, many packages are updated daily. It’s quite likely that a kernel patch would soon be out to make it play well with the nvidia driver. But so far, the easiest way to get X loaded is to boot using the older kernel, 2.6.30-10.
