Hello all.
I'm new one of this forum.

I need your help.

I need to access RHEL 6.6 with Xlaunch / Xming ( Putty).
But from my PC, if accessing with Xlaunch,
it shows APPCRASH of Xming after put the login-passwords.

From this system , I can access other RHEL7 and it works.

I did,
- check /var/log/Xorg.0.log
and found following error :
(WW) warning, (EE) error, (NI) not implemented, (??) unknown.
[ 23.161] Initializing built-in extension MIT-SCREEN-SAVER
[ 23.446] (EE) open /dev/dri/card0: No such file or directory
[ 23.521] (EE) open /dev/fb0: No such device
[ 24.095] (EE) AIGLX: reverting to software rendering
[604815.545] (EE) Server terminated successfully (0). Closing log file.

- export DISPLAY='PChost':0.0
xhost + shows "Unable to connect PChost:0.0".

-I also disable SELinux and reboot, and getenforce shows "Disabled",
but still Xlaunch is showing APPCRASH.

- service iptables STOP , but still see the same error.


I think that this Xorg is not working normally.
Xorg.log is ended following lines :

What should I check the configuration of this REHEL at next step?

Could you please give me an advice ?

Did you check the ssh config file on the server to be sure it permits remote x sessions? You might want to compare the configs on the server that works and the one that doesn't. The snippet of Xorg.0.log looks normal for an x session that ended correctly.

Finally, I cannot find out why Xming is down.
( there are no difference config about X ).

So, my friend help me to install VNC server,
and I could access from My PC with VNC viewer.

Anyway, thank you for all you he help!

Thanks.
