No additional output in xsession-errors. Reproducible: Always Steps to Reproduce: 1. 2 monitor system (gentoo), 2 or more pinned apps running on screen 2 2. Add pager Plugin to panel 3. Switch pinned applications by context menu or icon-box plugin Actual Results: Desktop disappears without any output in .xsession-errors Expected Results: Switch between running applications
Hmm, if the desktop disappears, there is at least also a problem in the xfdesktop code. Does the pager itself show up properly? Also, does it only occur with pinned applications? Hmm, I just tested a pinned application. Changing to it from the xfdesktop menulist gives me: (xfdesktop:5907): libxfcegui4-CRITICAL **: netk_workspace_activate: assertion `NETK_IS_WORKSPACE (space)' failed And clicking on the icon in the iconbox gives: (xfce4-panel:5931): libxfcegui4-CRITICAL **: netk_workspace_activate: assertion `NETK_IS_WORKSPACE (space)' failed So, I think I have an idea about where to look. I don't think it has anything to do with the pager, though, so there might also be another problem. Thanks for the report.
Yes, the pager itself shows up properly and it seems to be fully functional. As soon as I add the pager, the following output starts running: (xfce4-panel:4372): Gtk-WARNING **: gtk_widget_size_allocate(): attempt to allocate widget with width -3 and height 1 I have only been able to reproduce the error when the pager is part of the panel and I switched between 2 pinned applications.Then the desktop and the context menu (right click) disappear. The panel is still there and functional. No output in .xsession-errors (apart of the output mentioned above).
Closing this bug since we switched to wnck. Please reopen if you still have this problem with the Xfce 4.6 panel.
In xfce4-panel 4.6.1 on Ubuntu 9.10, my .xsession-errors file has hundreds of lines that look like: (xfce4-panel:1787): Gtk-WARNING **: gtk_widget_size_allocate(): attempt to allocate widget with width -11 and height 1 Is there a way to tell what's causing this?
