Getting graphics to work on my Xen-project DomU PV [solved]

folatt · 2016-02-07 09:30:14

- To clear things up a bit -

What I want:

A development environment where I can safely develop plugins for ArkOS, fix bugs in ArkOS and if necessary even develop new features on ArkOS.
ArkOS is a derivative OS of Arch Linux.

Why I want it:

I've achieved this via Virtualbox before, but running two graphical OSes, made my computer slow. It's especially annoying to see Eclipse slow down to a crisp whenever
I would scroll around. Sometimes the whole thing even crashed my computer.

So I thought, why not use two computers instead?
Keep leisure and hobby project separated and dividing the CPU/RAM workload across two computers.

How I want to achieve this:

Install Eclipse on my DomU and be able to use my home computer to somehow remotely login to my DomU and use Eclipse there.

My setup:

Computer #1 - leisure computer
OS: Ubuntu

Computer #2 - hobby project computer
Dom0 - OS: Arch Linux
L DomU - OS: Arch Linux/ArkOS

What I have achieved so far:

I have set up a Dom0.
I have set up a DomU.
I can open a console to my DomU.

My problem:

- No working connection from my leisure computer to my hobby project, or at least, not one that shows a desktop environment.
L In fact, I can't even start the desktop environment on my DomU itself, though I don't know if that's a necessity.

I now have a new computer because I thought perhaps it's AMD with it's odd drivers fault.

Because Xorg :0 -configure results in video card not found as I'm in a DomU, I created a xorg config file.

Both Dom0 and DomU are Arch linux.

Because `Xorg :0 -configure` results in video card not found
as I'm in a DomU, I created a xorg config file.

I have managed to get vncserver running on my DomU and was able to connect to it via tightvnc, but got a black screen.
One of my questions is, what does the line "vfb = ['vnc=1,vnclisten=0.0.0.0']" exactly do?

Is that supposed to enable me access to my DomU GUI via my Dom0? Can I use it access my DomU
via a remote vnc viewer?

/etc/X11/xorg.conf.d/10-monitor.conf

    Section "Monitor"
        Identifier             "Monitor0"
    EndSection

    Section "Device"
        Identifier             "Device0"
        Driver                 "vesa" 
    EndSection

    Section "Screen"
        Identifier             "Screen0"  
        Device                 "Device0"
        Monitor                "Monitor0"
        DefaultDepth           16 
        SubSection             "Display"
            Depth              16
            Modes              "1024x768_75.00" 
        EndSubSection
    EndSection

My `startx` output:

The whole problem seems to be my network bridge configuration, so all the info dump is irrelevant.

Thread needs to close and I will ask a new question.
