Desktop background not drawn correctly in xrandr dual screen mode
Last modified: 2011-04-04 03:23:39 UTC
If I connect an external screen to my notebook and use xrandr to use it as a second display (instead of clone mode) the wallpaper on my notebook gets cut off and parts of the screen are left without a background. Moving windows etc in this area leaves behind garbage. My setup: - notebook with 1280x800 screen (intel i965 graphics) - external screen set to 1024x768 and places on the left - "Virtual" screen size is set to (1280+1024=) 2304 800 What actually happens is that nautilus the wallpaper using the same screen width, e.g. even on the 1280 screen the wallpaper ends after 1024 pixels, like on the other screen where this is correct. I will attach a screenshot. To the left you see the external screen, to the right the internel one. Xterms have been placed to show where each screen ends. Note the stripe on the far right, which is the area without a background.

Weird, didn't happen back in the days where I played with this.
For the problem about the mouse moving into the "outside-the-monitors" area, see bug #394805. I'll investigate about the background stopping where it shouldn't.
And for the bug about the panel being in the external display instead of the internal one, see bug #433804.
Same issue here with KDE4 on SLED11 running on a Lenovo X60s. My setup was created with xrandr --output VGA --above LVDS I have loaded different wallpapers for both outputs LVDS a green one, VGA one with snow. In the larger VGA, it appears that the wallpapers are placed as if LVDS and VGA were side by side. the actual LVDS below the VGA and remains without wallpaper. The right-click-desktop menu is only available where wallpapers are. Nothing happens, when I try right click in the checkerboard area or in the black area.

The version with which you had the bug is now obsolete. I'll close this as NORESPONSE. If you can still reproduce it in current 11.4, please reopen the bug and move it to the appropriate version. Thanks!
