Steps to reproduce: 1) Start with a single-monitor configuration. For this example, I use the external screen VGA-0 attached to the laptop, while the laptop's LVDS is turned off. 2) `xrandr --output LVDS --auto --below VGA-0' makes the desktop extend to the laptop's LVDS, putting it below the external screen while the panels stay where they are. Expected results: Workspace switcher resembles the new screen size in its miniature view. Actual results: Workspace switcher still resembles the old screen size in its miniature view and seems not to know about the new screen configuration. Workaround: `xfce4-panel -r' Reply at: https://bugs.launchpad.net/ubuntu/+source/xfwm4/+bug/1241895/comments/0 ------------------------------------------------------------------------ On 2011-04-18T11:02:17+00:00 Yves-Alexis Perez wrote: Note that adding or removing a workspace seems to make the pager notice the layout change.

I started using XFCE a few weeks ago and initially I had a single-monitor setup and everything was fine. Then, through xrandr (using the arandr GUI tool), I expanded my desktop to cover the second monitor that I have hooked up, everything was still fine and the workspace switcher reflected that change. However when I now run an xrandr command to switch back to single- monitor, the workspace switcher doesn't update and keeps taking up space as though I have a dual-monitor setup. Running 'xfce4-panel -r', removing and re-adding the workspace switcher applet, restarting my XFCE session, or using the display settings application to fiddle with things (toggling my 2nd monitor to see if it would case everything to go back to normal) doesn't seem to help either. I've gone over all the settings under the settings editor to see if anything was left behind there but couldn't find anything wrong there either. So now I'm wondering; is what I'm having the same as this bug, but manifesting in a different way, or should I file a separate bug report for this?

Xfwm needs to be fixed to update the _NET_DESKTOP_GEOMETRY property. Long story: I have the same problem as Hans Nieser. I might have located the source of this bug. The Xfce pager uses libwnck, which uses the _NET_DESKTOP_GEOMETRY property to determine the full desktop size. However, it seems that Xfwm does not update the _NET_DESKTOP_GEOMETRY property http://standards.freedesktop.org/wm-spec/1.5/ar01s03.html According to the page above, this property should be set by the window manager. I verified that Xfwm indeed does not modify this property using the attached C file, which can be compiled via gcc test.c -lX11 -o test Steps: 1. Log in and enter xfce desktop. 2. Compile test.c and run ./test to verify that the desktop geometry is correct. 3. Change the screen configuration via xrandr by adding/removing a monitor, or change the virtual desktop size via "xrandr --fb widthxheight" (as along as the new size is big enough to hold the existing screen configuration). 4. Run ./test again and observe that the desktop geometry stays unchanged.

This fixes the issue that _NET_DESKTOP_GEOMETRY doesn't update, and makes the pager widget relayout correctly. One minor remaining issue (that I assume has nothing to do with xfwm4) is that I do need to click the pager widget once, or change workspace (or anything that forces it to update itself) to make it relayout correctly immediately after login, but that beats having to restart xfwm4 every time (`xfce-panel -r` never worked for me, btw, not sure why that worked for OP) Reply at: https://bugs.launchpad.net/ubuntu/+source/xfwm4/+bug/1241895/comments/6 ------------------------------------------------------------------------ On 2013-03-16T14:12:09+00:00 Yves-Alexis Perez wrote: (In reply to comment #6) > One minor remaining issue (that I assume has nothing to do with xfwm4) is > that I do need to click the pager widget once, or change workspace (or > anything that forces it to update itself) to make it relayout correctly > immediately after login, but that beats having to restart xfwm4 every time > (`xfce-panel -r` never worked for me, btw, not sure why that worked for OP) It was always the case, see comment #1.
