No GUI after installing Debian 8.2 with KDE on XENServer VM

    Hi there,

    I'm attempting to setup Debian 8.2 on a XENServer VM 6.5 SP1. I'm a newbie to Linux and have encountered a problem. The install completed but upon reboot it doesn't boot to KDE which I specified on the install as the default interface, it boots to the cmd prompt. The said machine is on my home LAN and I can connect the XS console fine.

    Post install, I've tried to reinstall KDE but it says its already installed. When I try to start x server i get the error message below...To confirm I've reinstalled the VM from scratch only to end at the same point.

    From googling I think I need to manually edit the xorg conf file. But to be honest I'm not really sure what I need to do to get Debian to boot to KDE.

    Any suggestions appreciated.

    I'm not sure if this will help much, but it appears something is wrong with the graphics driver (or lack of one). Try running
    apt-get install xorg
    then try starting the x server again.

    Hi jerz4lunch.

    I tried as suggested and found XORG is already installed.

    I played around with a few things and I think what's happening is that the VM cannot see my GPU under XENSEVER, hence the error, no screen found.
    - I've previously installed Debian 8.2 with this hardware as a stand alone OS successfully.
    - I've installed Debian 8.2 on Xenserver with my Radeon HD6450 which ended up with this issue (no screen error)
    - I disabled my Radeon HD6450, enabled my i5-3470s onboard graphics and installed Deb 8.2 with this issue (no screen error).

    This is why I think the might be an issue with the VM accessing the GPU under XENSERVER host.

    Has anyone else come across an issue like this?

    Unfortunately, I've never used XenServer, so I won't be able to help you any further. Hopefully someone else who's more knowledgeable with XenServer will find this article and help you.
