            Bug ID: 58867
          Assignee: intel-gfx-bugs at lists.freedesktop.org
           Summary: [GM45 regression] blurred graphics in 3.8_rc1 at
                    native display resolution (commit identified)
        QA Contact: intel-gfx-bugs at lists.freedesktop.org
          Severity: normal
    Classification: Unclassified
                OS: Linux (All)
          Reporter: andreas.sturmlechner at gmail.com
          Hardware: x86-64 (AMD64)
            Status: NEW
           Version: XOrg CVS
         Component: DRM/Intel
           Product: DRI

commit a726915cef1daab57aad4c5b5e4773822f0a4bf8 (drm/i915: resurrect panel lid
handling) which is otherwise a relief (it finally makes my X200s detect native
external display resolution correctly), seems to conflict with another change
in drm code. 1920x1200 is still chosen as it should be, but looks in fact as if
it were some badly scaled up non-native resolution, in terminal as well as X.

Test results so far:
3.6.11 +patch: all fine
3.7.1 vanilla: wrong std resolution, but sharp graphics once it is set up
3.7.1 +patch: correct std resolution, horrible looks
3.8_rc1-current git (contains the commit): same as above
