Edubuntu Setup Tips and Tricks

Update: We new have a separate LTSP related blog for Nepali Deployments, check it out here

A)
The usplash was giving resolution problem.
It was fixed by changing the /etc/usplash.conf file and setting
cat /etc/usplash.conf
xres=640
yres=480

Nice!!

B)
Now originally the client were successfully logging in, but after sometime they stopped working, it was strange but after debugging and following links below, i found that edubuntu and sabayon (gnomes configuration editor, or sth...)

The discussion links have been posted here
exactly my problem
https://lists.ubuntu.com/archives/edubuntu-users/2007-June/001199.html

then it forwarded to sth ssh related, update ltsp ssh keys
https://lists.ubuntu.com/archives/edubuntu-users/2007-June/001202.html

in the last link, there was option to simply remove sabayon and well guess what? it worked perfectly!!!
sudo aptitude remove sabayon

I was glad that there wasn't much dependencies related with sabayon.

B.1)HowEVER!!
I reinstalled sabayon watching so many cool stuffs about it on the net. All i needed to do was to add the users/client to the profile and done!!

C)
The server was giving problems with bad gdm login screen, was fixed easily by reconfiguring the x-server
sudo dpkg-reconfigure -phigh xserver-xorg

D) Local USB Mount missing!!
Asked about it in #edubuntu in freenode.net and got this link
https://bugs.launchpad.net/ubuntu/+source/ltsp/+bug/160420
and scanning for the fix, got to this place,
http://article.gmane.org/gmane.linux.terminal-server.general/22270

The modifications i made as mentioned in the mailing list above are
a) comment out
env['DISPLAY'] = 'localhost:10.0' to # env['DISPLAY'] = 'localhost:10.0' in
/usr/sbin/ltspfsmounter

b) in file /opt/ltsp/i386/usr/share/ldm/rc.d/S10-delayed-mounter,
add a -X line to ssh connection string like this
ssh -X -S ${LDM_SOCKET} ${LDM_SERVER} "/usr/sbin/ltspfsmounter ${DIR} add"

c) finally update the ltsp image by executing
sudo ltsp-update-image
