Description David Kovalsky 2012-02-22 00:29:44 UTC
When I connect an external display to my notebook and start the dual head, the desktop background changes back to the default. 

Once I switch back to single display (notebook only or external display only), my chosen background (image) is correctly set as the background. 

100% reproducible.

Comment 1 Kevin Fenzi 2012-02-24 16:14:08 UTC
Do you see the default on _both_ displays? Or just the new one?

I'll see if I can track this down some.

Comment 2 David Kovalsky 2012-02-24 16:48:57 UTC
Oh, now I realize I wasn't totally clear. Sorry about that. 

This happens when I'm in CLONE mode, both displays show the same. Thus the default is on both :) 

I've tested this in setup where I have the same resolution on both displays. And another time in setup where internal display resolution > external display resolution. No change. Clone always shows the default background. 


It doesn't happen in Cinerama setup, when the desktops are side-by-side (3840x1080) or under each other (1920x2160). One desktop shows my selected background and the other one the default. It's not perfect though - depending on in what order I enable/disable the displays my selected background is displayed either on the primary display or the secondary.

Comment 3 Christoph Wickert 2012-02-24 17:05:02 UTC
Did you already set a background for the second display in xfdesktop-settings? Once you attach a second display, the tab "Background" has sub-tabs, one tab for each display and you can (or better should be able to) set the wallpapers individually. I guess what happens is that the second display is configured to use the system default wallpaper, which then gets mirrored.

Comment 4 David Kovalsky 2012-02-24 17:24:33 UTC
Could be. 

Indeed if I set the desired background for the second display, then it gets me where I want to be. See my little son chasing a rabbit while I work :)

On the other hand, I'm unable to set a background for individual desktops. Even though I see 2 tabs (for 2 desktops/displays), changing any one of those changes BOTH background at the same time.

Comment 5 Kevin Fenzi 2012-03-26 00:55:32 UTC
So, then the bug here is that you can't set background for each desktop? 
Or?

Comment 6 David Kovalsky 2012-04-04 14:59:06 UTC
So the bug is actually a few issues: 

 * having a default background, it's changed to something else if I connect another display (until I set the background for the second display to show the same)

 * I can't have a different background for each desktop, even though the dialog suggests I can. I don't mind if the limitation is one background for all desktops and only the dialog gets modified. 

 * if only 1 background is set, it depends on how the external displays are organized and it's a bit random what's shown on the main

Comment 7 Fedora End Of Life 2013-01-17 00:58:25 UTC
This message is a reminder that Fedora 16 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 16. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora 
'version' of '16'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version prior to Fedora 16's end of life.

Bug Reporter: Thank you for reporting this issue and we are sorry that 
we may not be able to fix it before Fedora 16 is end of life. If you 
would still like to see this bug fixed and are able to reproduce it 
against a later version of Fedora, you are encouraged to click on 
"Clone This Bug" and open it against that version of Fedora.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

The process we are following is described here:

Comment 8 Fedora End Of Life 2013-02-14 02:33:33 UTC
Fedora 16 changed to end-of-life (EOL) status on 2013-02-12. Fedora 16 is 
no longer maintained, which means that it will not receive any further 
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of 
Fedora please feel free to reopen this bug against that version.

Thank you for reporting this bug and we are sorry it could not be fixed.
