[Bug 530976] [NEW] garbled graphics with 2.6.32-15 kernel

[Andreas Schildbach]

Public bug reported:

On an Geforce 8800GTS system connected to a Dell 2405FPW:

2.6.32-14 detected my monitor reasonably well and had no trouble displaying GDM and the desktop.
2.6.32-15 does not even get the resolutions right and displays only garbage instead of the desktop.
