I am in charge of the computer systems in our school and have set up a number of Ubuntu 11.10 machines in the classrooms and have a working Ubuntu Live-USB system in place for the students (Students have 16 GB sticks, with a full install of 11.10).

Over the last months, I got the machines to work quite well, especially the Live-USB works like a charm, however we have interactive SMART whiteboards in our classrooms and I downloaded and installed the SMART software to the computers which are used in the classrooms.

The problem is that Ubuntu randomly crahses when using (i.e. touching) the Smartboard. It happens almost only while writing or clicking on the board, but sometimes (much rarer) also in pauses between writing. When using other input methods (typing, mouse) there are alomst no problems (sometimes, when you really push the system, you might just manage to crash it). Also, the live USB, which is running on machines with the exact same setup save the harddisk and the CD drive (same mainboard, CPU, RAM, Peripherals etc.) works really well, there are, however, also isolated, but much rarer, crashes (1 random logoff per week or so).

By "crash" I mean either X crahses, logging you off and returning you to the login screen, Kernel panics which produce some output on the screen, or the system just going blank. Which one, seems to depend on the GDM and the Interface (gnome, unity, xfce…) which is used, with Unity just logging off, the others panicking. I've done a lot of googling, experimenting, installing and uninstalling stuff, and I'm afraid I'm out of ideas and suggestions. Could it also be a hardware issue? I'm using a Gigabyte GA-H61M-USB3-B3, H61 Mainboard, but couldn't find any know issues with it. I would be very grateful for any suggestions.

Thanks, Markus

PS: Today I also tried a fresh install of 10.04 LTS, as Smart explicitely states this version as "compatible" on their website, it actually only made matters worse (much more frequent crashes)
