I'm trying to find out why Lyx (version 2.1.1) closes down as soon as I choose shut down in the gnome menu. This does not seem to be a bug in Lyx, as running Lyx with gdb tells me that it has exited normally when I click shut down.I don't think it's related to any of the gnome shell extensions I've installed, as disabling all of them (and finding back gnome's power off button) doesn't change this weird behaviour.What happens always when choosing shut down, is that Lyx closes down. Sometimes, when I exit from the shut down dialog by cancel, the next time I click on shut down, nothing happens. So gnome seems affected by this strange behaviour as well, and I have to restart the computer from the terminal.FYI, the shut down dialog allows to suspend the computer; if it allowed only to power off or restart the machine, this would not have been an issue.Lyx is based on Qt, so the problem might be there as well.I'm running CentOS 7 with Gnome version 3.8.4.What is going on?
Choosing shut down or power off causes some programs to close
