Thanks.

Weird. Just to check: is the kernel from sid or 2.6.37 affected?
(The only packages from outside squeeze you should need in order to
test other than the kernel image are linux-base and initramfs-tools.
Historic kernels can be found at <http://snapshot.debian.org/>.)

I've re-installed the machine using one lenny instalation (not sure which
version) and there was no flickering. I've then upgraded to squeeze - not sure
which version - using another instalation CD) and the flickering was there.
I've then dist-upgraded and the flickering was still present. So I've done
what you asked in the previous e-mail: picked up the sources from squeeze,
applied twose two patches (but not the third), installed the resulting
linux-image and booted it: the flicker was still present.

I'll try to get some time tomorrow for testing 2.6.37+30 and up from
http://snapshot.debian.org/binary/linux-image-2.6-686/ until I find one that
doesn't flicker, and I'll let you know the results.

Best regards,

Thanks. To save time, it would help to check 3.2.6 first, and then
run a bisection search (i.e., cut the range to search for the fix in
half with each step by judicious choices of kernel to test) if the bug
is fixed there. A nice list of packages is at

http://snapshot.debian.org/package/linux-2.6/

Regards,
Jonathan

Default Bug#607227: screen flickers

Hi there,

I'm very very sorry, I've been wasting your time.
I finally got some time to test this, so I fired up the machine and...
the problem was gone. The silly thing that happened was that when
trying the new-compiled kernel, I chose the wrong one at boot time, so
I was sure I was testing the new kernel but I wasn't at all... Seems
that, after all, using patch 1 and 2 but not 3 was a solution after
all.

Sorry once again for the mistake, and if you want me to test anything
else just ask...

Best regards,
--

Oh, excellent! Thanks, Marcos. That's a comfort.
