Description Cédric Bellegarde 2009-07-03 15:46:04 UTC

Version:            (using Devel)
OS:                Linux
Installed from:    Compiled sources

On my dualscreen, i have a directory with some kdewallpapers (from official packages).

I set slideshow for screen1 with this dir.
Idem for screen2.

At login, slideshow start on screen 2 but i have default wallpaper color on screen 1 :/

Is this a dualhead (two x servers) or a dualscreen (2 screen, same xserver, like nvidia twinview) bug?

Comment 2 Jacob Welsh 2009-07-17 00:03:41 UTC

I also have this issue. It is a single X screen (can drag windows across monitors), with monitor boundaries reported through the Xinerama extension (nvidia twinview in my case).

In video card lingo, this is multihead (two card outputs). In X.org lingo, it's single-screen, multi-monitor (Xinerama, TwinView, XRandR 1.2 etc). In KDE lingo (and other desktops too) it's simply multi-screen. Confusing eh.

The (less common) alternative is a separate X screen (:0.0, :0.1) on each output. Windows cannot be moved between screens. Still a single X server though. Also known as "Zaphod mode multihead".

Back to the bug in question... if I right click the faulty desktop -> Desktop Settings -> OK, it will then initialize the slideshow.

I have this problem as well.  I'm using nvidia twinview to create a single desktop across two monitors.  As the other reporter's described, I can set a wallpaper slideshow just fine on both desktops, but next time I login the wallpaper is only active on the "first" monitor recognized by X (CRT-0) which is, incidentally, my secondary monitor.  My primary monitor (CRT-1) simply shows a blue background.

Are there any available workarounds for this until a proper fix is applied?  Eg., can I perhaps tell KDE to treat my desktop as a single desktop for the purposes of wallpaper, so that the wallpaper setting applies across both?

Thanks.

Confirmed here, too. Going to the Desktop Settings, it's enough to press the "Ok" button once, and the wallpaper slideshow will resume on both monitors.
