Re: [K12OSN] blue screen on Logoff



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 testserver i386]# tail -f /var/log/Xorg.0.log
[    40.549] AUDIT: Tue Jan  8 13:11:53 2013: 2422: client 23 disconnected
[    40.900] AUDIT: Tue Jan  8 13:11:53 2013: 2422: client 16 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.

It sounds like the TC is where the problem is. X session ends on server and local dm is not running as a service.

Hello Jim,


thanks for the reply. I will check this when getting back to work.

I assumed that log would just show output for the graphics card of the server and not of the thin client.

Greetings J.
