Synaptic tool is not starting on my Ubuntu 17.10, the window does not appear. It seems that root-user lacks privileges to access the window manager.
The following command will grant access to root to open an X-window on Ubuntu 17.10 for this session only.
Afterwards execute synaptic as super-user (root)
Die Lösung lautet 13, berechnet mit folgendem Python Programm:
for A in range(16):
for B in range(16):
C = 7;
D = 3;
for E in range(16):
F = 1;
for G in range(16):
H = 6
for I in range(16):
J = 2
if A+B+C == C+D+E and C+D+E == E+F+G and E+F+G== G+H+I and G+H+I == I+J+A:
The official Samsung driver (universal linux driver ULD) does not support access to the printer/scanner functionality via LAN. Seems, this driver supporting devices attached via USB.
For LAN access, just the Open Source Samsung Universal Linux Driver (SULD) is working for me (project page at http://www.bchemnet.com/suldr/index.html).
If you intend to install the SULD, you will need to perform the following steps (sudo-permissions are required on your host):
Install the packages libsane-extras, and xsane
sudo apt-get intall libsane-extras
sudo apt-get intall xsane
Install the SULD driver following the instructions from project http://www.bchemnet.com/suldr/index.html
The following steps must be performed, namely adding the SULD repository to your resource list, add the signature-key to your truststore, update the local database, and finally the installation of the suld-driver.
sudo bash -c 'echo "deb http://www.bchemnet.com/suldr/ debian extra" >> /etc/apt/sources.list'
sudo dpkg -i suldr-keyring_2_all.deb
rm -f suldr-keyring_2_all.deb
sudo apt-get update
sudo apt-get install suld-driver-4.01.17
Now add your user $USER to both groups “scanner” and “lp” (will require logout or reboot)
sudo usermod -a -G scanner $USER
sudo usermod -a -G lp $USER
After reboot and login, the tool “xsane” should discover the scanner, and you should be able to choose the printer in setup-tool.
