The Nymfe* stations are student stations in the PC hall and Linux classrooms (B130, A219). During the semester, the stations run from 7 a.m. to 8 p.m. on weekdays. If someone is logged in at 8 p.m., the machine will shut down at 10 p.m. Nymfe01 and Nymfe02 are the exception and run nonstop (except for the 5 p.m. reboot). Due to limited access to the FI network, the Nymfe* machines can only be remotely connected to the MU network (e.g. via the Aisa machine).
In addition to the usual remote access via SSH, you can also use remote access via VNC if needed.
You can also access the Windows home directory from Nymfe*.
The current station occupancy is shown on the room maps in the Faculty Administration.
You can also read about an earlier uncharacteristic problem we had with Nymphs.
Changing the language does not work in GNOME's graphical settings, but you need to change the environment variable
LANG, which is set in the
.bashrc file when you create an account.
So if we want to change the language to English, we change the line:
To apply the changes, we need to log out and log in from the graphical session.
If you are missing support for a language, let us know at
Warning. This method only works on sessions that use
xorg, and thus do not work in the new default session
Ubuntu, which uses
wayland. To use
x2x, you must use an appropriate session such as
Ubuntu on xorg or
With the help of
x2x you can control another Nymph machine (or a Nymph machine) from your laptop (this can be a useful alternative to free-standing monitors):
- Log in to the Nymph graphical session, which will serve as a "secondary display"
- find out the name of the display via
echo $DISPLAY- most often it is
:0, which we will assume below
from the other machine that will serve as the primary one, and whose keyboard and mouse you will use to control the other machine, log on to Nymfe:
notebook$ ssh -Y xlogin@nymfeNN xlogin@nymfeNN$ x2x -to :0 -east
if all goes well, the command will sort of get stuck; if you then hover your mouse over the "eastern" edge of the laptop screen, the cursor should go to the secondary screen and you should be able to control the windows with both the mouse and the laptop keyboard
You can choose other locations based on cardinal directions, but this may not always work. In particular, if you have the Unity interface on your laptop (the default for Ubuntu),
-west and the most natural
-north cannot be used due to the presence of Gnome Shell's bars. For XMonad or if you have problems with maximized windows, you may still need to use
-struts. Copying may also be a problem - try using the middle mouse button then. (No, transitively chaining several Nymphs in a row is probably not possible.)

Origin of the name
The name Nymphe comes from Greek mythology: the water, forest and mountain goddess of the Greeks and Romans, similar to our fairies and rusalkas.
