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.
