Is it on a virtual machine? (KVM? ) Looks like there is no screen specified.

It's not KVM, it's a VPS but I'm not sure what virtualisation type is...
Hi,
It is clear that your VPS solution does not allow you to have a video buffer. You can either install an X manager (such as Xming an Open/Source project) on your workstation and run X through LAN if you have a fast connection or you can install/activate VNC service and connect to your server over it.
Cheers,
K.

Hi KeremE,
But should X be started before using Xming or VNC?
Thanks!
But should X be started before using Xming or VNC?
Thanks!
goall:
- Start Xming before you start any x11 application
- With VNC you don't need to start the xserver as vnc brings its own.

XMing is an X server and it will run over your remote workstation and yes it should be started and your display must be set.
- Start XMing over your Personal Workstation
- Allow connection from your CentOS server through XMing Setup.
- SSH to your CentOS BOX.
- Set Display environment variable with these commands:
VNC must be started earlier in your CentOS 6.2 in fact if you enable it will start automatically during startup or you can use service command to start it.

BTW if you have never started VNC bebore I suggest you to configure it:
- Edit your /etc/sysconfig/vncservers and uncomment last 2 lines
- replace myusername with your username who will connect to your system.
- If you're using the default display allow TCP port 5902 through your firewall
- start vncserver from the command line so that it ill create ~/.vnc directory structure
- enter a password to use in vnc connection
- use killall vncserver and remove /tmp/.X11-unix/X0
- edit ~/.vnc/xstartup. uncomment "exec /etc/X11/xinit/xinitrc" save and exit
- start vncserver service

Hi,
Managed to login and see the display. But the problem is I see a black display (with that blue CentOS wallpaper) but no buttons no desktop no nothing.
When I try to start the gnome-session, I receive a error:
Warning: Cannot open display

Also make sure that /etc/sysconfig/xservers line has aline like that:
Don't forget to replace myusername with the username you want to logon to X.
VNCSERVERS="2:myusername"Don't forget to replace myusername with the username you want to logon to X.

/etc/sysconfig/vncservers
Firewall is down (flushed)

Unfortunately I see only the wallpaper...
/etc/sysconfig/vncservers
VNCSERVERS="1:pwg3n2"
VNCSERVERARGS[2]="-geometry 800x600"Firewall is down (flushed)
