           Summary: Can't set lower resolution for LVDS panel
        QA Contact: intel-gfx-bugs at lists.freedesktop.org
          Severity: blocker
    Classification: Unclassified
                OS: Linux (All)
          Reporter: long.bu at intel.com
          Hardware: x86-64 (AMD64)
            Status: NEW
           Version: git
         Component: Driver/intel
           Product: xorg

Hardware Platform: Intel H61

There is a LVDS panel attached to DP port through a DP2LVDS converter.

The native resolution of the LVDS panel is 1024x768.

We can see the supported resolution is 1024x768 and 848x480.

However, we want to set the resolution to 800x600, which will fail.

And we can set to 800x600 on Windows with the same hardware.
