Dear All,

I've setup a server from scratch to be able to test this further.

In /var/log/Xorg_0_log I see no EM:

[root at testserver i386]# tail -f /var/log/Xorg.0.log
[    40.549] AUDIT: Tue Jan  8 13:11:53 2013: 2422: client 23 disconnected

This is my /var/lib/tftpboot/ltsp/i386/lts.conf:

[default]
     # X_COLOR_DEPTH=16
     LDM_LANGUAGE=nl_BE.UTF_8
     LOCALDEV=True
     SOUND=True
     X_NUMLOCK=True
     NBD_SWAP=True
     SYSLOG_HOST=server
     LDM_GLOBAL_DMRC=/etc/ltsp/ldm-global-dmrc
     XKBLAYOUT=be
     #LDM_NUMLOCK=true
     SCREEN_01=ldm
     # LDM_DIRECTX=yes is very insecure, but it is faster and more scalable
     LDM_DIRECTX=yes
     # LDM_DEBUG=yes writes to /var/log/ldm.log during client runtime
     LDM_DEBUG=yes

The thinclient has an AMD Radeon HD 6290 graphical card, I think that is 
the problem.

But I don't know where to make adjustments .

Can anyone help?

Thanks for any reply.

Greetings, J.
