Hello,
I recently installed the freenx package of my distribution Arch Linux on
my desktop and the nxclient package on my laptop.
After following the HowTo to configure it, I tried to access the server
from my laptop with nxclient.
This worked up to the point where it said
Session Startup Failed
I tried playing with the init commands, as in, I tried: xterm, ion3,
default and so on.
After that i turned on debugging.. well I just show you the logs:
Oh yes: the client is 32Bit, the server 64Bit...
File session:
xrdb: No such file or directory
xrdb: Can't open display ':1000'
xterm Xt error: Can't open display: :1000

I noted the segfault of common comands like mv, rm, mkdir in the log, so i
tried to put own commands in the nxnode scriipt to get more information.
But no matter which command i put in (whoami, pwd, ls,touch) they all
segfaulted. However, doing the same in nxserver did work.
I appretiate any help :)
