Default 200 lines and fat client

Well, fat client does not seem so easy to setup than server/thin client.

All the files are same as in server side and I made a new image.

When I open gnome-terminal I got this.

bash: /dev/cgroup/cpu/user/2098/tasks: Does not exist
bash: /dev/cgroup/cpu/user/2098/notify_on_release: Does not exist

ltsp000@ltsp200:~$ mount

ltsp000@ltsp200:~$

ltsp000@ltsp200:~$ cat /etc/rc.local
#!/bin/sh -e

mkdir -p /dev/cgroup/cpu
mount -t cgroup cgroup /dev/cgroup/cpu -o cpu
mkdir -m 0777 /dev/cgroup/cpu/user
echo "/usr/local/sbin/cgroup_clean" > /dev/cgroup/cpu/release_agent

exit 0
ltsp000@ltsp200:~$

-----

Where that 'cgroup' mount goes in fat clients? I installed that mount
after boot by hand in fat client.

ltsp000@ltsp200:~$ ssh root@ltsp200

There is lot's of file systems indeed ;-)

Just wondering.

I logged out and in and opened four 3D games in fat client (Atom/ION). No
problem. Very responsive desktop.

I hope we got this one to the next Ubuntu 10.04 update, 10.04.2 January 27th.
