Description mjrauhal 2005-02-13 10:44:16 UTC 
Please describe the problem:
On Xinerama with displays on non-uniform height, trying to maximize windows
vertically on the smaller display works fine, but on the larger one windows are
completely maximized when using it. After unmaximizing, the windows remain
properly vertically maximized.

Steps to reproduce:
1. Configure Xinerama so that displays are of non-uniform height
2. Try to vertically maximize a window on the larger display
3. Unmaximize the window to actually get the desired effect


Actual results:
Window is first maximized completely.

Expected results:
Only vertical maximization.

Does this happen every time?
Yes.

Ok, on Gnome 2.10 (metacity 2.10) on Ubuntu Hoary preview with a 2x1600x1200
MergedFB desktop this same bug still occurs but in a weirder fashion: Any window
whose right edge is within perhaps 5-10 pixels of the right edge of either of
the screens is first completely maximized when trying to vertically maximize,
and reverts to only vertical maximization once unmaximized. Windows not
bordering on the right edge of either screen seem to vertically maximize fine.
Comment 2 Rob Adams 2005-03-16 00:58:54 UTC 
the problem is that onscreen contraints aren't xinerama-aware; they're based on
the root window width and height.  With non-uniform xinerama heights its also
possible to drag the window completely off the screen into the void region.
Comment 3 mjrauhal 2005-03-16 01:01:17 UTC 
I'll just clarify that the new triggers of the bug I noted in comment #1 occur
with 2 same-sized screens  (both 1600x1200).
Comment 4 Jean-Yves Lefort 2005-04-11 12:42:27 UTC 
I can confirm the behaviour described in comment #1. Here's a snippet from my
Device section in xorg.conf:

Driver "nvidia"
Option "ConnectedMonitor" "CRT, TV"
Option "TwinView"
Option "TwinViewOrientation" "Clone"
Option "MetaModes" "1280x960,NULL; 640x480,640x480; 800x600,800x600;
1024x768,1024x768"

I can reproduce the bug in all modes, even 1280x960 (which is not cloned).
Comment 5 Elijah Newren 2005-04-27 20:05:11 UTC 
I suspect this may be a duplicate of bug 302204.  Could someone with Xinerama
try the patch in that bug and report whether that fixes the issue?
Comment 6 Ignacy Gawedzki 2005-05-26 08:57:20 UTC 
This fixes it for me (2 x 2048x1536).  Thanks
Comment 7 Elijah Newren 2005-05-26 17:08:02 UTC 
Cool, I'll mark as a duplicate then, thanks Ignacy.
