= Trouble Shooting - Software

== Stopping Programs

- **never** stop a not hanging program with ctrl+c
 - when a restart of the program is really necessary use .q instead
 - restarting a program is in most cases not a solution and only increase the risk to trigger more problems. So avoid restarting programs as long as possible 

== Starting Programs

Do not forget **start.sh** before all programs! It makes sure that the programs are automatically restarted.[[BR]]
When you start a program from /home/fact/operation, this is taken care of automatically by links. 

== vnc and screen == 

All programs are running all the time and run either in a screen or in a vnc session.

For the screen sessions, there are configuration files which contain the setup such that all programs are started automatically.[[BR]]
0. check if a screen session is running (to a running session you connect with ''screen -x'')
0. if none is running start one with ''screen -c .screenrc_configfile'' (where the names and paths of these config files can be found below)
More useful screen commands: [wiki:ScreenSessionHelpfulCommands]

For the vnc-session: 

0. check if a screen session is running, e.g. ''ps aux | grep vnc''
0. if none is running, start one: ''vncserver :1'' where :1 stands for desktop 1. You can also give the size with e.g. ''--geometry '1600x1050' ''

=== vnc-session on AUX ===

tpoint (displays tpoint camera image) is running on aux

to restart it: [[BR]]
''cd /home/fact/Drive.new/FACT++''[[BR]]
''./tpoint''[[BR]]

=== vnc-session on GUI ===

on gui you can start the old gui (not needed as you have smartfact)

in case you need the old gui, go to the screen on gui and do[[BR]]
cd operation[[BR]]
''fact''[[BR]]

be aware that this is as defined in .bashrc
