Description Sean Quinlan 2008-06-23 21:16:00 UTC
Version:            (using KDE 4.0.4)
Installed from:    SuSE RPMs
OS:                Linux

Desktop configuration for KDE 4 does not yet seem to support dual monitors when setting wallpapers. You can launch the desktop configuration tool from either desktop and set the wallpaper for only the monitor on which the application was launched. The configuration tool should be aware of both monitors and be able to set the wallpaper for both together (Xinerama mode) as well. Support for this was present in KDE 3.

Thank you

I have just tested KDE 4.1 from the open suse factory repository and this bug still exists

Why is this marked as a duplicate of bz 155150?  This seems like it is the exact opposite of that bug.   

This bug appears to be wanting to be able to use 1 wallpaper with 2 monitors (spanning both).  155150 appears to be wanting to be able to use a different wallpaper on each monitor (which appears to be the way it behaves now).

Unless I'm missing something (which is a real possibility), this bug should not be a duplicate of 155150, and 155150 seems to be the current behavior (4.1.3).

I'm sorry I missed this. Justin is correct, this is _NOT_ a duplicate of 155150.

Hello, long-time user of KDE returning to it after a hiatus of about 14 months. KDE 4.2.1 is gorgeous and stable to boot, congratulations to everyone who has been working for years on this. I had been using a dual-monitor setup on KDE 3 and have collected several wallpapers specifically for dual-monitor setups such as mine. 

Since I can set the wallpapers for each screen individually, I realised that I could just vertically split the 2560x1024 wallpapers using Imagemagick. To save others the pure frustration I went through of trying to parse the incredibly well-meaning but incredibly opaque imagemagick website, here are the steps to split an image very very simply. 

we're assuming that the image is called x.jpg and that it is 2560x1024 in size (2560=1280*2). We're going to create 2 1280x1024 images, xL.jpg for the left and xR.jpg for the right.

1. Step 1
~$ convert x.jpg -crop 1280x1024+0+0 xL.jpg
2. Step 2
~$ convert x.jpg -crop 1280x1024+1280+0 xR.jpg

Set the wallpaper for the left screen to xL.jpg and the wallpaper of the right screen to xR.jpg by right clicking on each screen and selecting Appearance Settings > Wallpaper 

It's simple now that I've figured it out but people shouldn't have to do this. Just a comment, totally not a flame, much love and kisses for all the work on KDE 4. You guys rock.

Thanks a million for this tip. Your awesome! and I hope this will get sorted out in the long run.

The downside to Daniel's solution, which I use myself, is that it precludes using the Slideshow feature because the left and right image sides will get shuffled randomly.

Obviously this is not a show-stopper, but I did kinda like having multiple desktops with different dual-screen backgrounds on each that cycled every hour.  So I'm adding votes to this and to 155150.

Confirming this issue. It still persists in KDE 4.9.x.
Is there any suggested implementation idea to get this bug fixed?
Comment 10 Aniruddha Shankar 2012-11-03 20:59:57 UTC
To be fair, dual monitors are pretty recent technology; perhaps there's not that much demand for something so cutting-edge.

Then we should consider KDE3 (namely kdesktop) more recent technology than KDE4 plasma, because kdesktop supported this just fine.

I'm just assuming your being "sarcastic" or somewhere in the "funny" area now. KDE 3 handled this just fine.

Hello!

This feature request was filed for KDE Plasma 4, which reached end-of-support status in August 2015. KDE Plasma 5's desktop shell has been almost completely rewritten for better performance and usability, so it is likely that this feature request is already implemented in Plasma 5, or is no longer applicable.

Accordingly, we hope you understand why we must close this feature request. If the requested feature is still desired but not implemented in KDE Plasma 5.12 or later, please feel free to open a new ticket in the "plasmashell" product after reading https://community.kde.org/Get_Involved/Bug_Reporting

If you would like to get involved in KDE's bug triaging effort so that future mass bug closes like this are less likely, please read https://community.kde.org/Get_Involved#Bug_Triaging

Thanks for your understanding!

Nate Graham
