Hi Jonas

With the sources you used the failure is as described below:

source for the second one is here:

ajoliveira.com/ajoliveira/gen/bin/xorg-driver-sis671_0.9.tar.gz

I have all the dev modules you have yourself installed.

Thanks for helping, this is weird, 2 lucid systems should behave the same way, if properly loaded. Not that my system is fully upgraded. I didn't compile on a 32-bit machine cause my other laptop has undergo through a similar regression process, no display using an intel 852/855 chipset with lucid, no wireless, total collapse, will see if I catchup later on.

Cheers
