Bug#650002: network-manager-gnome: connection to WiFi leads to 'Gtk-WARNING **: cannot open display: :0.0'
Package: network-manager-gnome Version: 0.9.2.0-1 Severity: normal Dear Maintainer, connecting to wireless LAN leads to the fact that it is impossible to open any new window (since a dist-upgrade yesterday). Typing a command in a previously opened terminal that normally opens a new window (e.g. `mousepad') leads to the following message: 'No protocol specified (mousepad:3883): Gtk-WARNING **: cannot open display: :0.0' If any further info is needed I will try to provide it.

Did the DHCP server send a hostname? how can I check that? You can run NetworkManager in debug mode [1]. But given it is set to dhcppc0, that's most likely what happened. Do you have the ifupdown plugin enabled in /etc/NetworkManager/NetworkManager.conf? [ifupdown] managed=false setting it to true and restarting makes no difference.

I meant: [main] plugins=ifupdown It was [main] plugins=keyfile I set it to [main] plugins=ifupdown,keyfile This solved the problem of changing hostnames after restart. But with the nice side effect that all windows were missing titles and buttons to control them (the cross ... usually in the upper right corner). Deleting ~/.cache, ~/.dconf and ~/.gconf/system solved that (I deleted all at a time, thus I don't know which one really did it). regards, Tom [1] https://live.gnome.org/NetworkManager/Debugging -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of unsubscribe.
