What do you mean by "ulgy lines" when running in native resolution ? can
you be more explicit ? Is this related to overlay or happens in
general ? Have you tried option "LVDSProbePLL" "true" in your Device
section ? (My patch adds this option to help with the panels who need a
specific timing, though I may decide to make it default to true on LVDS
flat panels when there is no BIOS infos ...)
