Hi Alkis, sorry for delay.

I followed your instructions after having installed a fresh Ubuntu 
14.04.3 desktop image on the server.

Connection from client finishes with the same error, but now from 
x-session-manager:

Oct  8 19:11:25 TOO-LTSP x-session-manager[2980]: WARNING: software 
acceleration check failed: Child process exited with code 1
Oct  8 19:11:25 TOO-LTSP x-session-manager[2980]: CRITICAL: We failed, 
but the fail whale is dead. Sorry....

Did'nt you face this error?

My server is an HP  Compaq dc5850 Small Form Factor (AJ459AV) with AMD 
Athlon(tm) Dual Core Processor 5000B

If someone had an idea on how to solve this issue, would be great :-)

Daniel
