Gdm fails to start
On Ubuntu 18.04 I managed to end up in a situation where gdm won't be able to start.
Syslog has this trace :
Jan 11 14:12:59 llandwerlin-hsw-laptop gdm3: Child process -1909 was already dead. Jan 11 14:12:59 llandwerlin-hsw-laptop gdm3: GLib: g_hash_table_find: assertion 'version == hash_table->version' failed
Last time I dig into this, removing some .desktop file made it work. Could gdm/glib be fixed not to prevent startup when a desktop file isn't parsable?
