-Some applications are clearly designed for use by a single user on a single system, and some of this doesn't scale well to n users on m systems (something like n*m comes to mind). In other words, things come to a grinding halt, complicated even more by the lack of disk quota on the home disk, whereas $HOME is one of the few locations an application can count on to exist on any system. Here are some tips to get around that kind of problem.+Some applications are clearly designed for use by a single user on a single system, and some of this doesn't scale well to n users on m systems (something like n*m comes to mind).

-However, the data and cache parts can become quite big, causing two problems: quota usage on the home disk, and performance loss (since the home disk is remote, and this can cause lots of read and write access). +However, the data and cache parts can become quite big, causing two problems: [[disk quota]] usage on the home disk, and performance loss (since the home disk is remote, and this can cause lots of read and write access). 
 Now the XDG standard provides a mechanism to move those files to another location, and we suggest users move them to one of their local data disks. We also provide a script [[sfinx-xdg]] that takes care of the environment setup, but selecting a location and moving the files is something you can do yourself. By default (2019-03-20) the cache is moved for all users to the local /data1, unless they set another location. Now the XDG standard provides a mechanism to move those files to another location, and we suggest users move them to one of their local data disks.

 +===== ClipIt clipboard manager =====
 +The ClipIt tool provides a history of cut and paste actions. Very useful... If it works. And unfortunately, it often doesn't work (mostly related to damaged history files, or insufficient disk quota at some point).
 +So, it you don't require the feature, or if it simply blocks any cut & paste action in your session, just exit the program or remove it from your session startup applications.
 +  - Exit the program: find the ClipIt icon in the system tray. It looks like a clipboard with a document next to it. \n Right-click on the icon and choose "quit"
 +  - If the icon is not there, try the command: 'pkill clipit'
 +  - To permanently remove it from your session, go to the system settings in the main desktop menu, choose "startup application" and move the clider next to "ClipIt"
