I put a .profile in /home/housad  with the 'xhost +192.168.0.254'
chown housad:housad .profile

then did the following...and then got these Xlib errors...so wondering?? 
how can we solve this? =)

[root at ltsp root]# who
housad   ws248.ltsp:0 Nov  1 15:55 (ws248.ltsp)
root     pts/1        Nov  1 15:57 (10.1.3.128)
root     :0           Oct 15 15:58
[root at ltsp root]# xmessage -center -timeout 30 -display ws248.ltsp:0.0
