Comment 13 for bug 451305

I am using Kubuntu 9.10, and just applied the most recent updates suggested by KPackageKit.

It installed "linux-headers-2.6.31-15" among other packages.

When rebooting, the beautiful login screen did not appear. Instead, an error message regarding the screen dimensions appeared, and I could only access the system in the command-line interface.

Then, I ran "sudo shutdown -r now"...

In the GRUB menu, there are new options for the "2.6.31-15" kernel (including the new default). I had to manually select "2.6.31-14", and fortunately the "beautiful login screen" appeared, and here I am, using the KDE interface.

I am an intermediate user - not an absolute newbie, but also not an experiencied user. Anyway, this situation is not "comfortable": I simply accepted the updates suggested by KPackageKit, and the result is that my system does not boot nicely as before...

As I have nVidia drivers installed, and the error message mentions screen size, and I found this bug in Launchpad, I am reporting this here - I hope I am in the right place...

Please, if possible, help me by telling me what should I type in the command-line to "fix" the "2.6.31-15" boot, to make it start X-server + KDE normally. Also, help me to provide more information - I don't know what other information should I be including here, so you can have more resources to help me.

Thanks!
