Description Dylan Griffiths 2006-06-27 04:31:42 UTC

Version:            (using KDE KDE 3.5.3)
Installed from:    Ubuntu Packages
OS:                Linux

Well, whoevere fixed bug 42778 did it wrong.  I had 2 monitors setup; then I said, "hey, I'll set a different background for each of my two monitors."  After a few days, though, I decided that the second head wasn't worth having around.

I edited my Xorg config, disconnected the monitor, and logged out/reset X.  Naturally, as the head removed was Xinerama 1, I got Xinerama 1's background on my main monitor (Xinerama 2) when KDE came up.  "No problem, I'll simply reset the background image."

Well, it turns out it is a problem.  The "fix" for bug 42778 is such that if you have some Xinerama overrides in your KDE config, but you don't have Xinerama, you're stuck with those choices -- the code will not check to see that Xinerama is disabled and revert, nor does it present you with the Xinerama-specific config dialog that can change the settings.

To put it another way, I can select, "Use no background picture" and apply it, and still have the same Xinerama-1 background picture staring me in the face on my desktop.

 -- seems like a simple fix; no Xinerama?  Ignore screen specific settings.

The DrawBackgroundPerScreen_* settings should be ignored if there is only one screen. Or, alternatively, these settings should be available in the configuration dialog even if one screen is present, which would be somewhat confusing. Right now, the setting being true inhibits any configuration through the "Configure Desktop" window.

i second on this,
i will regularly alternate between dualscreen, or just the laptop screen. 
and if i 'want' to change my background, i have to manually clean ~/.kde/share/config/kdesktoprc -> end session -> sign in -> reset my preferences

Kdesktop is no more mantained. Fortunatly this bug seems not to be valid for
KDE 4. Please reopen if this bug is not a kdesktop one (and it is not solved)
or it can be reproduced on KDE 4.

Bug closed. Kdesktop is no more mantained.
