[Bug 477134] Re: X server hard crash when kubuntu System Settings Display app is started

 

Following Martin's suggestion from Bug #490274 I added nomodeset to the
kernel command line and all was well with kernels 2.6.31-14 and
2.6.31-15. When I picked up the update to 2.6.31-16 today things broke
*worse*. It is still the case that booting without nomodeset and
invoking the KDE display setting app causes the same X crash and a
completely unusable machine.

However, with the 2.6.31-16 kernel *and* nomodeset, the display settings
app now (usually but not always) produces a corrupt screen that is black
for the top 1/3 and mouse clicks either are not reported as occurring in
the correct location or are completely ignored -- I can't tell which.

So this new kernel is represents regression rather than progress for
i965gm users. I'm tempted to open a new bug -- this one (4771334) is
really about behavior when KMS is active. With the -16 kernel there
seems to be a problem even when KMS is not being used. Thoughts?
