I am mounting a NFS-folder from a server to my laptop.
Unfortunately, the server goes off sometimes... The problem is, that I cannot unmount the "dead" NFS-folder. On the command-line, I get "device is busy", and via nautilus it crashes my current session.
Is there any way to unmount a NFS-folder when the server is off?
I have two folders (ORIGINAL A and ORIGINAL B), and both do have subfolders.
How do I merge these two folders (and subfolders) to DESTINATION C?
a) ORIGINAL A and ORIGINAL B do have the same subfolders. I want to copy every unique file of any subfolder into the "correct" subfolder of DESTINATION C
b) some subfolders are only in ORIGINAL A, but not in ORIGINAL B. I want any folder in DESTINATION C
Does anyone know a terminal command?
i am running Kubuntu 10.10 on my WeTab Tablet PC. As this Tablet has no mouse (but a touchscreen), I would like to configure Kubuntu in a way that allows to perform a right-click.
In Ubuntu (not Kubuntu), there is an option to just hold the left-click for about 3 seconds in order to perform a right-click (Mouse => Accessibility => "Trigger secondary click by holding down the primary button").
I can't find something similar in Kubuntu...
Is there a terminal-command that backups thunderbird's addressbook?
I would like to set up a cron-entry for that. Note that I only want to back up the address book, not my entire profile.
I am using GNU R to calculate a huge dataset. My PC has 4 CPU-cores, and I can see, that R is using only 1 CPU.
Is there a way to tell R to use all 4 CPUs in order to make the calculation complete faster?
I try to suspend my server using dbus and UPower. The server runs Ubuntu LucidLynx 64bit.
While everything works fine if I am sitting directly at the machine, it won't work via ssh. If I connect to the server via ssh and try to suspend the machine using dbus and upower, it gives back
dbus.exceptions.DBusException: org.freedesktop.UPower.GeneralError: not authorized
Could anyone please tell me how to configure dbus in order to allow ssh-users to suspend the machine?
