I’m working on setting up Ubuntu 12.04.5 in a classroom environment here in San Antonio, Texas. We hope to replace several labs currently running Windows XP that connect to a Citrix farm. This version of Ubuntu was selected to be compatible with NetSupport software that teachers use to monitor a classroom.
The OS is installed on HP dc7700u and dc7600u computers. I followed online directions for creating a Windows 7-style Ubuntu desktop (looks and works very nice too). There are two user accounts on this system, one for Students without the rights to install applications (all games removed) and the other for Administrators with full access. On boot up, the Student ID is logged in with the option to not require a password (as seen below).
After having everything almost at the testing stage I came across a problem. I get a graphics error when I log off the student user to try to use the Administrator account. Up until this point, everything has been running great. As soon as I log off, the system locks up with “The system is running in low-graphics mode”, input device settings could not be detected correctly. The next option is “What would you like to do?”
In most cases the mouse and keyboard do not work. A couple of times when I could make a selection I have tried all options but nothing happened. I can power down the system and it boots into Student user without any problems.

- Run in low-graphics mode for just one session
- Reconfigure graphics
- Troubleshoot the error
- Exit to console login
