OK, I start xterm in localapps.
$ glxinfo
bash: glxinfo: command not found

Now I don't know what to do.

Make sure it's installed _in the client chroot_ and that the client  
image is updated.

Re: Graphics acceleration

Now I'm sure the graphics card is properly configured. But I have big 
problems with kwin performance. The programs work well and quickly (eg 
Firefox), the window manager is a disastrously. Very slow and several 
artifacts. The server is a HP585 + 4X2800 + 8GB RAM, clients are celeron 
700 with 512 MB RAM and Radeon 9000. What can I do to understand where 
is the problem?

nbd-update-config issues on Ubuntu 11.10 upgrade

Here is an account of a learning/troubleshooting experience that
Google may some day find for the help of others.

Today I upgraded my home LTSP server to Ubuntu 11.10 using Ubuntu's 
built-in command-line distribution upgrade tool, then worked through the 
suggestions on the web page at
   https://help.ubuntu.com/community/UbuntuLTSP/UpdatingChroot

A problem occurred, which I could reproduce by running the script
   sudo ltsp-update-image --arch i386
In detail, the diagnostic message follows:
======================================================
Traceback (most recent call last):
   File "/usr/share/ltsp/scripts/nbd-update-config", line 17, in <module>
     if "/etc/nbd-server/config" not in

   File "/usr/lib/python2.7/ConfigParser.py", line 297, in read
     self._read(fp, filename)
   File "/usr/lib/python2.7/ConfigParser.py", line 538, in _read

Does sabayon Gnome profile editor work for you?

Dear readers,

When I click Edit in sabayon on Ubuntu 11.04 it crashes. I have tried
it on Fedora 14 and Fedora 15 as well, where it also crashes.

Have anyone been able to use it to edit Gnome profiles with?

If not, how do you customize the menu and menu bar so all users get this?

Lots of love,
Louise

The problem comes from KDE's Oxygen theme which use a lot of network bandwith. 
Here after changing style, windows decoration and desktop theme, every 
artifacts dispeared.
I've also changed several other things to use KDE 4 with my LTSP network at a 
reasonable speed. Below is my memo list and some of my config files (can't 
access everything at the moment).

Hope this help
xavier

Remove graphics artifacts
1. Change desktop theme to "opaquity" desktop (no transparency)
install theme in /usr/local/share/kde4/apps/desktoptheme/opaquity
and symlink /usr/share/kde4/apps/desktoptheme/opaquity
2. Use Tabstrip kwin style
3. Use Kde legacy cursorTheme
4. Use Phase style (without gradients)

Prevent fat xsession-errors 
run kdebugdialog -> deselect all -> apply
this should stop errors being saved in .xsession-errors
