Hey guys, I think I found a small bug. I am running xfce4 from the current Ubuntu 12.04 version (xfwm4 4.8.3-1ubuntu1, xfce4-panel 4.8.6-2ubuntu2, xfce4-session 4.8.3-0ubuntu2). I use NVidia TwinView for dual screens and I place one panel on each monitor, each having the window buttons within. Furthermore, I unchecked the "Show windows from all monitors" option, so that I see the windows of each monitor only on it's on panel. So far so good. However, if I restart xfce, both panels show no windows at all. If I now go to the window buttons options (of one of the panels, doesn't matter which) and I check and immediately uncheck "Show windows from all monitors", it works again as expected and the windows appear in the panel. Thank you Flo By the way: I already noticed this bug in Ubuntu 11.10, so I guess it has been around for a while.
I also get this, doesn't happen every startup mind. uname -a: Linux 3.10-3-amd64 #1 SMP Debian 3.10.11-1 (2013-09-10) x86_64 GNU/Linux aptitude show xfce4: 4.10.1
Right, I have done some work on this, but am giving up. This is not just a twinview problem - this trivially happens when you add a second monitor - started happening immediately in a Debian VM when I did that. However, while the problem recurred a few times, I later relogged in >10 times and didn't see the issue - this prevents me from getting an understanding of how the code works and putting proper debug code in. I repeated the same test on my real workstation and again I could relogin 10 times without issue. Since I don't normally logout, and its such a trivial workaround, I can't really spend more time on this unless it happens much more. When it did occur, it went away on a panel restart, so I have added the following to run on startup: =============================================== bash -c 'killall xfce4-panel && xfce4-panel &' =============================================== I hopefully will never see it again ;)
I would mark this as a dupe of #10725
