            Bug ID: 88965
           Summary: screen is not centered when activating second display
           Product: DRI
           Version: unspecified
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/Intel
          Assignee: intel-gfx-bugs at lists.freedesktop.org
          Reporter: lists.jjorge at free.fr

x11-driver-video-intel-2.99.917 (Mageia 4 Revision: 811713)

I use this two commands to switch from mono display to dual desktops:

SINGLE
xrandr --output VGA1 --off

DUAL
xrandr --output VGA1 --auto;sleep 1;xrandr --output VGA1 --pos 1790x0

Very often, when switching back to SINGLE, the image is only half visible, the
rest of the screen is black. BUT THE MOUSE CURSOR CAN GO OVER ALL THE SCREEN.
The clicks of mouse are at the good place, so all is like framebuffer comes
back in the bad place.

I can workaround this switching back to DUAL and the front SINGLE again several
times, till all is good.

This is a regression that does not happen with x11-driver-video-intel-2.21.15.
