XFCE 4.10 panel auto hide feature stops working on occasions
I realize that this won't give you a permanent fix for your issue. But, this is a workaround that I have found useful and will keep you from having to reboot constantly.
Since upgrading to Xfce 4.10, I have had an issue with window decorations not always being visible upon log in. I have used the following command to fix it:
You can reset your Xfce desktop, without restarting, using the command xfwm4 --replace
.
Or, you can try this to just reset the panels:
Resetting the panels can be done with xfce4-panel -r
.
Finally, there is an open bug with the auto-hide feature in Xfce 4.10, although it has only been confirmed in Ubuntu 12.10.
Update 2017-02-07: This appears to have been fixed in Ubuntu 15.10.
