           Summary: [ILK] Corrupted screen rotation using xrandr with
                    PageFlip enabled.

          Severity: normal
    Classification: Unclassified
                OS: Linux (All)
          Reporter: hamer.mk at gmail.com
          Hardware: x86-64 (AMD64)
            Status: NEW

         Component: Driver/intel
           Product: xorg

I have Lenovo ThinkPad X201 tablet with Intel Core i7 L-620 (Intel HD Graphics
gen 5).

I use «xrandr --output LVDS --rotate inverted» to rotate screen 180° for tablet
mode. But somewhere around version 2.99.912 of xf86-video-intel this feature
was broken.
Please see video here: http://youtu.be/JjAScg4MZNk
On «test 1» and «test 3» the «PageFlip» option uses default value (enabled) and
screen redrawing is corrupted.
On «test 2» and «test 4» the «PageFlip» option is disabled in «xorg.conf» and
screen redrawing is good.

I use:
Debian testing
kernel 3.15.10
xf86-video-intel 2.99.916 from git
KDE 4.14
