Re: debian-6.0.7-amd64 how to set resolution and refresh for free NVIDIA X drivers?
Since you are willing and able to reinstall from scratch, it may be worth
trying the next release of Debian, currently considered 'testing', known
as 'wheezy'. You can get wheezy Release Candidate 1 release installation
media from here:
Wheezy is to be released imminently, so it should not be significantly more
unstable to use than you would expect from a stable release. However it is
much newer than squeeze, and the open source nouveau driver has been under
rapid development, so the version in wheezy is likely to have a much larger
set of supported cards, and many bugs squashed compared to squeeze.
Once you've done that, if you could try attaching a Xorg.0.log that results
in running X *without an xorg.conf*, that may be useful too.
