[gentoo-user] 2.6.23-gentoo-r7 causes blinking X display

[gentoo-user] 2.6.23-gentoo-r7 causes blinking X display

[Grant Edwards]

I recently tried switching from linux-2.6.23-gentoo-r9 to
linux-2.6.24-gentoo-r7.  The latter is configured as
indentically as possible to the former, but when I run X under
the 2.6.24 kernel, one of my two displays blinks off every
10-20 seconds (it's off for about 1 second, then comes back
on).

The blinking doesn't happen with the 2.6.23 kernel.

The blinking doesn't happen in console mode.

I'm running nvidia-drivers 169.09-r1 with a NVIDIA GPU Quadro
NVS 290 (G86GL), connected via DVI to dual Samsung 204B
displays running at 1600x1200.

There's nothing in the system or X logs that conicides with the
blinking.

I'm a bit baffled as to how to troubleshoot the problem other
than stick with 2.6.23 and hope that a newer kernel rev fixes
things...

Did you rebuild the nvidia-drivers module?

Yes.  The exact same version of nvidia-drivers was being used
for both kernels.

Any other changes with things that could possibly influence the building 
of the drivers, like X libraries and such?

I'd save the current module (/lib/modues/2.6.23-gentoo-r9/somewehere 
there/nvidia.ko, maybe quickpkg will also work), re-build the drivers for 
that kernel and check if it still unaffected. If so, you could try the 
other kernels between those revisions, or vanilla-sources, and narrow 
down the cause.

Good luck, that's a nasty problem you have.

I don't think so.  I rebuilt the nvidia-drivers for both
kernels within minutes of each other without changing anything
else.  At least that's what I thought I did.  I'll rebuild them
again to make sure.

Um ... just to be clear, that means you did something like 
"emerge nvidia-drivers" *after* you built the kernel, right?

Right.  And after I changed /usr/src/linux to point to the new
kernel source tree.  Otherwise I'd get no X at all because
there's no nvidia kernel module.

I also did another emerge nvidia-drivers again with
/usr/src/linux pointed to the "old" kernel to make sure that
the kernel was the only difference.

What's the output of dmesg while this is happening?

Good question.  I looked in /var/log/messages and
/var/log/X<whatever>.  I don't think I looked at the output of
dmesg.  I'll give that a try tomorrow.
