           Summary: Merged Xinerama not restoring sizes from fullscreen
           Product: xorg
           Version: 7.1
          Platform: x86 (IA32)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/Radeon
        AssignedTo: xorg-driver-ati at lists.x.org
        ReportedBy: michael at frog.wheelycreek.net


I have an ATI (native Xorg) driver on a Radeon 9200 card set up with 2 screens
as non-rectangular, merged xinerama, with an offset specified.

When an application goes into fullscreen (which is usually undesirable since
very few applications bother to correctly identify the xinerama screen and so
place themselves over the centre of the 2 screens somewhere), and then switches
back out of fullscreen, it leaves various things in very weird states (I'll get
to describing them).

Relevant xorg.conf settings:
MergedFB true
MergedXinerama true
MergedNonRectangular true
CRT2Position "Rightof 150"
MetaModes "1280x1024-1024x768   ...."

Screen 0 is LCD - 1 is CRT.

Definition of weird:
Screen 0 is left with some 'no-go' zones for the mouse, but looks ok - size has
been restored correctly.  The bottom 1/4 of the screen is no-go, and a small
square in the top-right of the screen is also no-go.

Screen 1 is in the correct resloution, but is suddenly got a larger virtual
vertical resolution - and so scrolls.  However apps like the 'kicker' which hug
the bottom of the screen, are still left where the screen should be finishing -
and not at the new 'virtual' bottom of the screen.

I've also noticed (possibly unrelated, but happened about the same time - don't
ask me what version - 7.1, but other than that *shrug*) that when the rhs
kicker pannel is on the top of the screen and is scrolled away, then I can't
drag apps in the LHS screen applications past the top of the RHS screen - even
though maximising them works ok. Yakuake also drops down from the wrong spot in
the lhs screen.  This could be a kde problem - but I'm including it here for
completeness.

Other than that - my Xorg 7.1 is debian package 7.1.0-11
Kernel is 2.6.17 Beyond-4.
