X :1 -query s390vm.example.com
The command connects to the remote X server via XDMCP (replace
s390vm.example.com
with
the hostname of the remote X server) and displays the remote graphical login screen on display
:1
of the client system (usually accessible by using the Ctrl-Alt-F8 key combination).
You may also access remote desktop sessions using a nested X server, which opens the
remote desktop as a window in your current X session.
Xnest
allows users to open a remote
desktop nested within their local X session. For example, run
Xnest
using the following
command, replacing
s390vm.example.com
with the hostname of the remote X server:
Xnest :1 -query s390vm.example.com
3.2. Problems When You Try to Log In
If you did not create a user account in the Setup Agent, log in as root and use the password
you assigned to root.
If you cannot remember your root password, boot your system as
linux single
.
Once you have booted into single user mode and have access to the
#
prompt, you must type
passwd root
, which allows you to enter a new password for root. At this point you can type
shutdown -r now
to reboot the system with the new root password.
If you cannot remember your user account password, you must become root. To become root,
type
su -
and enter your root password when prompted. Then, type
passwd <username>
. This
allows you to enter a new password for the specified user account.
If the graphical login screen does not appear, check your hardware for compatibility issues. The
Hardware Compatibility List can be found at:

3.3. Your Printer Does Not Work
If you are not sure how to set up your printer or are having trouble getting it to work properly, try
using the Printer Configuration Tool.
Type the
system-config-printer
command at a shell prompt to launch the Printer
Configuration Tool. If you are not root, it prompts you for the root password to continue.
