| − | You can run full graphical remote desktop inside container using [http://en.wikipedia.org/wiki/NX_technology NX technology]. This is handy for when you work from home and you wish to run a web browser on your work's internal network to access local resources. You can use NX client to connect to remote NX server.
| + | My goals were simply to be able to connect to a VE using an NX client. This is handy for when I work from home and wish to run a web browser on my work's internal network to access local resources. I connect using a gutsy desktop and using nxclient. |

| − | [http://www.x2go.org/ x2go] is a related project that uses a fork of the NX3 GPL'ed libraries and works fairly well and doesn't have the limitations that the free (gratis) version of NX from NoMachine has. x2goserver and x2goclient packages are available as stock packages in several distros including Fedora 19 and 20, as well as being available for RHEL6/clones via the EPEL repository. If you can't find x2go packages in your distro's stock repository, check the x2go website for packages. x2go is actually easier to setup. Just install the desired GUI desktop inside of your container, install x2goserver, enable the x2gocleansessions service, make sure sshd is enabled... and connect as a user account over ssh via the x2goclient from the desired remote machine making sure to select the appropriate settings in the client.

| |
| − | </pre>
| |
| − | while installing the libxcomp package, just force-install the libxcomp package:
| |
| − | <pre>
| |
| − | # cd /var/cache/apt/archives
| |
| − | # dpkg --force-all -i libxcomp3_3.1.0-6-2_i386.deb
| |
| − | # apt-get -f install
| |
| − | </pre>
| |

| |
| − | You '''can't print from VE''' to client PC easily because printing in NX is realized via samba-mount of shared client's printer and CIFS isn't virtualized yet.
