Title:
Duplicated panels using separate x screens
Status in Desktop panel for GNOME:
Unknown
Status in “gnome-panel” package in Ubuntu:
Fix Released
Bug description:
I'm trying to use separate x screens on nvidia card with 3 monitors.
I'm expecting one top panel + one bottom panel on each screen, but
instead i have got all panels on one screen.
Restarting gnome panel (gnome-panel --replace) it will create two
extra (blank) panel pairs on same screen, but new applets will be
added on first panel pair. Screenshot ilustrating problem can be found
here - http://askubuntu.com/questions/177226/duplicated-menu-panel-
indicators-and-taskbar
I tried to manualy set screen key (org->gnome->gnome-
panel->layout->toplevels->top-panel->screen) on wich screen panel
should appear with dconf Editor. But restarting gnome-panel that key
will be reseted.
Downloaded gnome-panel source code (apt-get source gnome-panel), spend
some time trying to find problem, and probably i found it in file
panel-toplevel.c.
Line 4458: if (!screen || GDK_IS_SCREEN (screen))
Line 4459: screen = gdk_screen_get_default ();
These lines are responsible for resetting screen key. It will reset
screen to default if currenct screen exist, but its not what we want.
We want reset screen to default if screen dosnt exist, so line 4458
should be - if (!screen || !GDK_IS_SCREEN (screen))
After compiling and installing new package, gnome panel works as
expected.
