x11vnc – a real X11 display.

Sometimes one wants to connect to a real X11 display (i.e. one attached to a physical monitor, keyboard, and mouse: a Workstation or a SunRay session) from far away. Maybe you want to close down an application cleanly rather than using kill, or want to work a bit in an already running application, or would like to help a distant colleague solve a problem with their desktop, or would just like to work out on the deck for a while. This is where x11vnc is useful.
and here you can find a lot more information: http://www.karlrunge.com/x11vnc/

install x11vnc and then on remote machine as user type:

x11vnc -display :0

and then on your local machine type:

vncviewer IP

XFCE and ecryptfs-utils issue.

I use eCryptfs to encrypting a home directory. After upgrade the ecryptfs-utils package to 103 version. I’m not able to log into XFC using a LightDM, the unlock doesn’t work. The LightDM runs in the loop and displays a login screen
again and again. So, the solution is add the following:

auth optional pam_ecryptfs.so unwrap
password optional pam_ecryptfs.so
session optional pam_ecryptfs.so unwrap

to the /etc/pam.d/lightdm file, or:

common-auth-pc, common-session-pc and common-password-pc files into the /etc/pam.d directory

or using:

pam-config -a --ecryptfs should add it automatically to the proper common-* files.

By the way, the bug was fixed after a few hours by openSUSE maintainer 🙂
