After installing http://www.morokeni.ch/edubuntu/gnome-watchdog_0.9.2_i386.deb
User's processes are now purged after they log out. If they do not log out, however, and just reboot the terminal, their processes continue to run until they log in again. At this point watchdog notes that they already have running pid's and resets the user. This works, and the teacher observes that something similar was in place with the K12LTSP. This is a pretty substantial bug, I believe. The average user integrating Edubuntu into a thin-client lab and expecting it to perform reliably may not track down this fix. Without gnome-watchdog, users who log out have processes that continue to run throughout the day. On days when the teacher has 5 classes of 30 different students, the runaway processes get out of control. I installed prelink yesterday, after classes, and I am hoping that this will improve performance. I seem to recall Eric integrating this into the K12LTSP. The few test clients I tried loaded it much faster. Last, I have followed these suggestions http://www.zolved.com/synapse/view_content/28209/How_to_make_OpenOffice_run_faster_in_Ubuntu and they made a monumental difference on my home machines. I'll test this in the lab next week. Switching to a different window manager is not an option. This teacher has been running the K12LTSP since before Fedora was created. I am perpetually reminded that "it wasn't this way with the K12LTSP" when things are not quite the same. I am doing my best to figure out all the tweaks Eric H. and other integrated to make it great. --scott Fredrik Jansson wrote: > Hi, > > We've run edubuntu 7.10 about a week and we don't have any problems caused by > OpenOffice.
