Firefox 3 + (Ubuntu) LTSP bug
 
Hey All,

(This is in reference to
https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/269188 )

I talked with fta this morning and he has a PPA with updated nspr
packages, which supposedly fix the FF3 slowness/entropy issue that has
been discussed in LTSP lists before, which also affects Edubuntu LTSP users.

I haven't tested this exact procedure yet but this could be *the* fix
for Firefox 3 in (Ubuntu) LTSP - anyone care to comment? I'll be testing
it out at one school today hopefully.

Please keep in mind that when performing this, you need to launch AS
MANY INSTANCES AS POSSIBLE SIMULTANEOUSLY. It's easy for me to do, as I
run mostly LTSP lab environments with many machines in the same area. So
I just go down the line, after users are logged in, and clickity-click.

My request is for people that are affected by this bug to test and
report at the bug report listed at the bottom of the wiki page, so we
can get an SRU for Hardy, so FF3 is more usable in LTSP environments.
Thanks all!


- Jordan/Lns

Jordan, I have a setup for two servers (dhcp failover) and about 100
thin clients (HP t5125/5135).

This is what I did today with one classroom, about 10 thin clients. I
started FF and opened my Blip.TV page (asmokoskinen.blip.tv) one by one.
Then I took these screenshots.

To me there was no very long delays between thin clients/FFs.

Here are facts about servers:

Tell me - how I can help/test more and what I should looking for?

Best Regards Asmo Koskinen.

Asmo,

Well you just helped ME by introducing me to htop - very cool util,
never heard of it!

If you were having issues with launching multiple Firefox instances on
different TCs and them hanging and/or complaining "Firefox is already
running" when it wasn't, and now you're not (after installing nspr
package from PPA) then we're doing good. Please report on the bug I
listed in the previous e-mail so we can continue to push for an SRU.

Thanks for the testing,
Jordan
