Hi. I also see this problem frequently--probably every time that updates are available. I'm here because I saw it again this morning.
I leave the computer on overnight (since suspend doesn't work for me in 14.04) and when I arrive at work in the morning, System Update is often running but won't appear. This morning when I clicked it, it switched to another workspace, but no window. Clicked it again, and it switched back to the first workspace, but still no window. Since 14.04 decided to do away with the "Updates available" in the "gear" menu, I don't even know how to launch system updates. There was a context-menu option on the launcher icon for the updater, which offered to install all available updates. I don't know if that would have worked, because I always review the updates before installing. I also have two monitors. Both are plugged in and turned on when I see the problem. Of course, at night the monitors are turned off, and that is when the updater usually gets launched. So perhaps it does have something to do with a cable plugged in (one is HDMI, one is DVI) with no attached monitor that is turned on. What's worse is I that when I hit Win-R to launch the "run" menu and type "software updater", it happily lists it as an option (but only with the "gears" icon) and when I click it nothing happens. How is it that it's not accessible via the "run" menu? I actually came across this bug today because I couldn't figure out how to run the thing manually. I can do "apt-get upgrade" from the command line and have some idea of what's being installed, but not with the detail that the software updater provides. 14.04 has some nice touches, but I sure miss how solid 12.04 was... -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1003950 Title: launcher does not show minimized update manager while clicked To manage notifications about this bug go to: https://bugs.launchpad.net/unity/+bug/1003950/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
