Question from our Linux Support Person
We are new to this environment. We have Red Hap Release 5.0 running on our z10 under z/VM. It is booted and things appeared to be going well until I was asked this question by our Linux Team Member: "How do I start a graphical interface from mainframe linux install on X windows?". He is in the installation process and this process wants to use a graphical interface. Thanks in advance.

Re: Question from our Linux Support Person
When you install RedHat -- you can specify a 'vnc' install -- they should use that.Then they can connect with either a vnc client or web browser to do the installation. They specify this either in the 'parm' file used at install time (just the word 'vnc' will do) -- or select it it when asked by the installation dialog.

The same way you do on Intel Linux: set DISPLAY=xdisplayhost:0.0; export DISPLAY And run his application. He will need to authorize the X client to his X server as normally done when you run a X client on a remote host. -- For LINUX-390 subscribe / signoff / archive access instructions, send email to lists...@vm.marist.edu with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390 -- For more information on Linux on System z, visit http://wiki.linuxvm.org/
Re: Question from our Linux Support Person
Jim -- What I think I hear is that he wants to install an additional software package to the already installed and running Linux system, yes? (As opposed to performing an installation of Linux itself.) So ... he probably has a Linux desktop. If so, then he should ssh -X linuxonz and run the installation command(s) from that remote shell. The "-X" flag on the SSH command explicitly enables "X forwarding" so that the remote shell has access to his desktop screen and keyboard. (The default is frequently to leave "X forwarding" disabled, but sometimes it is enabled by default.) One step at a time. See if that works. But ... good hygiene is to #1 require root privs for product installation and #2 to not let people sign on as root directly. If these are both true for you, then passing X access from his desktop to the privileged shell gets a little trickier. We'll cross that bridge when/if we get to it. Scott and Pat mentioned VNC. VNC is good (and Scott was I believe specifically talking about for Linux system installation). Your guy *can* use VNC to get a virtual X "desktop" on the mainframe Linux system, but the window manager will probably be TWM (unless he knows VNC well enough to change it), which he will probably not like. I am okay with TWM in small doses. What Dave Boyes suggested should happen automagically if you 'ssh -X remotehost'. Try it. -- R; <>< Rick Troth Velocity Software http://www.velocitysoftware.com/ On Mon, Apr 11, 2011 at 11:39, Hughes, Jim wrote: > We are new to this environment.

Re: Question from our Linux Support Person
And if he doesn't know enough of VNC to change from twm to something else, you can install mwm, or the heavy gnome-desktop, and just edit ~/.vnc/xstartup and change from twm to mwm or gnome-desktop.
