Red Hat Bugzilla – Bug 374371
Maximizing Window while Compiz Enabled in Dock Doesn't Size Correctly
Last modified: 2008-08-02 19:40:36 EDT
Description of problem:
If "desktop effects" are enabled while laptop is in docking station and using
external screen, maximizing any window does not fill desktop. Instead, window's
size matches laptop screen size, not external monitor size.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Dock laptop with external 19" monitor (Dell 1900FP).
2. Enable Desktop Effects
3. Maximize any window.
Maximized windows are sized as if screen is 15.1 laptop screen.
Maximized windows would be sized to fit external 19" LCD screen (Dell 1900FP)
When laptop is not docked and desktop effects are enabled, the windows maximize
as expected. This is only a problem when the laptop is docked. This is a Dell
Latitude D610 with onboard Intel 915MP video in a D/Port Advanced Port Replicator.
same problem here, seems related to the RandR extension.
If I display the status using the xrandr utility, I get this listing:

Just one monitor here, using the VGA-0 output at 1280x1024. When using compiz,
windows are maximized at the 1152x864 resolution, and also mplayer in full
screen mode plays videos using this resolution. mplayer does the same also when
I'm not using compiz, so I think that this bug should be filed to something
related to RandR.
If I disable the DVI-O output (xrandr --output DVI-0 --off) all works perfectly
(compiz AND mplayer).
I also have the same problem with only one monitor. I have a normal resolution
of 1280x1024 through VGA, but when I enable desktop effects, windows are
maximized to 1152x864.
I found a workaround that is to reduce the resolution to 1024x768 and then
restore it to the original 1280x1024. This is effective while in the same
session (in other words, if I logout and then login again, the effect of the
workaround is lost and I have to do it again), but I can enable and disable
compiz as much as I want while in the same session without losing the effect.
Same problem with one 19 inch monitor at 1440x900. Windows are scaled to about
