Note: This issue is now resolved with the release of VIPM 2014 for Linux. Download here.
If you are experiencing problem with logging on to your Linux machine after installing VIPM, it is possibly due to the permissions to some files not set correctly.
There is a known bug where any VIPM operation will change the permissions on tmp folder which will prevent subsequent launch of LabVIEW or even possibly logging on to the machine.
Here is a workaround to take care of this problem manually.
Anytime after exiting VIPM,
1. Open shell window
2. Change tmp folder permission to 777 (you may have to do that as a root user)
If you are having trouble logging in the machine,
1. Log in as root
2. Set the permissions of tmp folder to 777
3. Log out and login as a regular user and you are all set.
You can even create a bash file that will reset the permissions to tmp folder to 777 after VIPM exits.
