Hi,

Thank you for your response. Below are the messages:

1) First, I already installed "Desktop environment"

2) When I execute "startx" command, it is giving the below messages:

(EE) NV(0): No display devices found
(EE) Screen(S) found, but none have a usuable configuration.
Fatal server error:
No screens found
XIO: fatal IO error 104 (connection reset by peer) on X server ":0.0"
after 0 requests (0 known processed) with 0 events remaining.

Log File Contents: (/var/log/Xorg.0.log)

using config file "/etc/X11/xorg.conf"
ServerLayOut "Default Layout"
Screen "Default screen" (0)
Monitor "Generic monitor"
Device "nVidia Corporation NVIDIA default card"
------------
------------
The directory "/usr/X11R6/lib/X11/fonts/misc" does not exist
Entry deleted from font path

I hope that this information is sufficient to analyze the problem to get the graphical desktop.

Thank you.
