Public bug reported:
I have a couple of NFS directories mounted on /share/XXXX via a wireless
connection. If I log out of GNOME and log back into GNOME, it works
fine. However, if I log out of GNOME and the wireless connection in KDE
is not set to "Connect Automatically" or if it has the incorrect key,
then when I log into KDE, the desktop hangs, presumably because it is
trying to access the NFS mounted directories without a working wireless
connection.
NOTE: These directories are mounted on /share (the /home directory is
local), so I don't know why KDE would access these directories anyway.
I found two workarounds:
(1) Unmount the directories in GNOME before logging into KDE. (NOTE: You
have to do this _before_ logging out. If you wait until KDE hangs and
then try to type Ctrl-Alt-F1 to unmount the directories, it won't work,
since the wireless network connection isn't there.
(2) Set the wireless connection to "Connect Automatically."
This can be confusing, because if, for example, the WPA key changes, it
suddenly becomes impossible to log in to KDE. You have to unmount the
NFS directories first, then log into KDE, then select the wireless
connection and click "Connect Automatically". Then you can mount the NFS
directories again.
In my case, I had reinstalled wireless drivers, which required me to re-
enter the WPA key, but I couldn't get a working plasma-desktop running
in order to set everything up.
I'm running Ubuntu 9.10
KDE 4.3
I believe the correct behaviour should be either to run whatever process
is accessing the NFS mounted directories in parallel with the other
desktop processes, so it doesn't hang the desktop and prevent things
like the menu from working, or at least to display a message "waiting
for network", so it's clear to the user why the system is hung.
