Been playing with Ubuntu Netbook Remix on my Acer Aspire One 110. Before I wiped the SSD and sent the netbook to repairs I had this same problem the panels on gnome window manager disappear, in both classic desktop and the Ubuntu Netbook Desktop. Searching the forums I found the solution :
This a bug in the desktop-switcher package (https://bugs.edge.launchpad.net/desk…er/+bug/349519), which I’m trying to fix and get uploaded to Jaunty before release.
To fix the issue you have currently (gnome-panel and/or windowmanager not starting), please run the following command depending on which mode your currently running in:
If in Netbook-mode, should execute:
gconftool-2 –set /desktop/gnome/session/required_components_list –type list –list-type=string ["windowmanager","panel"]
If in Classic mode:
gconftool-2 –set /desktop/gnome/session/required_components_list –type list –list-type=string ["windowmanager","panel","filemanager"]
