    Default how to setup "nohup" for remote X-session: i.e., it can temporally disconnected and later resumed in GUI mode?

    Dear all,

    I need your help.

    I am a student who do research using Exceed to access Sun workstation in our
    school to use Cadence EDA software. Due to Microsoft's security hole, they
    frequently roll-out new security updates.

    The system manager at our school has a software to automatically download
    and push those new updates to our computer. The problem is: it auto-restarts
    my PC... while I am running Cadence software remotely using Exceed...

    This month I have a bunch jobs killed in this way by the new security
    updates automatical restart! One of them I had runned for 6 days and it was
    killed. I am very angry about this!

    I know "nohup" can make sure that the process is running even if logout. But
    how about Cadence software which has graphical output.

    Imagine I use "nohup icfb", where "icfb" is the Cadence EDA software that I
    am using, it has a graphical output. Then my computer was restarted, and
    then I relogin, restart my Exceed, the "icfb" process is still there, but
    its graphical interface is gone...

    By the way, "icfb" is strange that it cannot be used "nohup icfb &"...

    What can I do now? Please help me!

    You can talk to your systems adminstrator.

    You can also run the software on a vnc server and use the vnc viewer
    to connect to it.

    Or, you can try and install a not-so bug ridden and reboot requiring
    operating system and work from that.

    How to tell if there is VNC server installed on the remote Unix machine?

    Do you need to actually _do_ anything with the Cadence software when you first
    start it up? If it just produces output and doesn't need any input...then
    you can use Xvfb, which is a "fake" X display.

    VNC, as others have mentioned, is a good idea as well.

    Another possibility, of course, is to get a Linux box and not do the whole
    Microsoft update thing. :)
