Thanks for your comments Mark. I worked with Scott Balnaeves in #ltsp and he ported the old X_RAMPERC from LTSP4 to LTSP5 for me. I did post the instructions for implementing X_RAMPERC to the edubuntu-users list (didn't think of posting here) https://lists.ubuntu.com/archives/edubuntu-users/2007-September/thread.html#1850 (There needs to be some changes to lts.conf as well, In playing I found that setting X_RAMPERC=80 to be about the best) . Firefox is also doing a ton of work on this some of which can be referenced in these two bug posts:
Good news is that it looks like Firefox 3 will have a bunch more features to work with pixmap cache and be very easy to tailor to thin clients, but that is out a few months yet.
I also brought this up on the xorg mailing list in this thread:
This is also a problem with xorg in the fact that it should not let any client consume it's resources and crash. The thread has a bunch of good thoughts on future improvements, though I don't think they have decided to make any permanent changes (Other apps can crash Xorg as well such as OpenOffice, so more than just FF needs a fix).
Also here is the thread that started things on edubuntu-users:
Sorry I forgot about this bug report and did not post back any of the progress. Also it should be noted that this is not a problem specific to Ubuntu, but all Linux distributions running Firefox, and also to a handful of other apps when running under xorg.
