Hi, are you using Edubuntu 7.04 ? If so I have noticed that a lot of people are having a lot of problems with it. I was having problems where the terminals and even the server would just freeze sometimes while the kids were doing their thing, mainly TuxPaint and Gcompris as the kids are all in grade 1 and 2. After seeing how many problems other people were having with 7.04, I went back to Edubuntu 6.06. Problems solved :) I may be wrong, I'm no linux guru, but is just seems to me that Edubuntu 7.04 is unstable...

The best I can do to repeat the problem for troubleshooting is to create a new Writer document, insert a few graphics from openclipart (5 seems to be plenty), then try printing to one of our HP LaserJet 4000 printers, mouse gets a little jerky, sometimes graphics pop up all over the top of the screen, then before anything prints the client locks up. I have monitored CPU/Memory usage with htop on the server, with htop in screen 1 on the client, with xrestop on the client from screen 7, memory usage with free on screen 1, and can not find a single spike in anything that seems to lead up to the freeze. However if I look at /home/username/.xsession-errors I do see some funky stuff that might start to tell a story. See below, I added some comments to help see a timeline: First cleared all stale processes for the user then boot client -- Log in as user, results below Xsession: X session started for jim at Thu Sep 13 14:58:58 CDT 2007 Setting IM through im-switch for locale=en_US.

Sometimes the client freezes sooner than others. I can also reproduce some errors on saving a file or while simply making changes to a document with the graphics already inserted. But printing seems to be a sure fire way to freeze every time. I have un-installed xterminator, scim, and DIRECTX support thinking they may be a problem. No effect. I remember a couple of weeks ago David Trask reported similar problems when working in Writer and Impress. Below are some more errors I have seen, maybe some extra errors will give more clues: Window manager warning: Buggy client sent a _NET_ACTIVE_WINDOW message with a timestamp of 0 for 0x260005d (OpenOffice) Window manager warning: meta_window_activate called by a pager with a 0 timestamp; the pager needs to be fixed.
