Start Debian without Monitor??

(1/12) > >>

Hello,

Recently I assembled a mini itx computer with Debian amd64.
I liked very much the performance of Debian/jriver 21 combo.
1. How to start debian without a monitor? It does not boot!!!
2. How to set up a vnc server??

I followed the Raspberry tutorial, but don't think it aplied to debian os.

Thanks

Antonio

The raspbian tutorial (the relevant part) should work on regular Debian.  Have you tried hooking up a monitor to it while it boots to see what's happening at boot?

Hi,

When I connect a Monitor, it does boot.

Also, I used the x11vnc (instead of tightvncserver), because tight gave me a Grey screen.
I have just replaced the tightvncserver name to x11vnc in the nano ~/headless (sorry , I am a Linux newbie)
I cant do vnc and alson I cant boot headless

Thanks

Hi,

Again!

I returned to tightvncserver to give a better explanation of the problem.
I did the same as you did in the raspberry tutorial , but with few doubts.
1. I replaced the name Pi to Debian (how to see my system`s name???)
2. I noticed that tightserver is not loading with the boot. When I start it at console, I can vnc it, but with Grey screen (The gui did not appear)

You can't use x11vnc that way because it relies on mirroring the physical display.  When there's no monitor connected, Debian doesn't initialize the physical display, so x11vnc has nothing to mirror.  So you either need to use tightvnc (which creates a virtual desktop), or you need to modify your X configuration to force it to initialize the physical display even when no monitor is present.  Your system is almost certainly booting correctly, it's just not loading the GUI (i.e. you could probably ssh in to try and fiddle with it).

1. You should replace pi with your user's login name not your system name, as noted on the pi tutorial
--- Quote --- NOTE: If you're using a different username than "pi", you should replace all instances of "pi" in the code below with your username.
--- End quote ---

2. It's probably not loading at boot because you didn't give it the correct user name to run as, and it's trying to run as a non-existent user.

The reason you're seeing the grey screen is that that's the default configuration of debian and VNC (it loads a very minimal xserver, and that's the main way that it's different from the pi); if you run mediacenter after that, it should appear on the gray screen.  If you want a full desktop experience, you'll need to tell VNC to load your desktop environment or window manager by editing the file at ~/.vnc/xstartup

If you can tell me what desktop environment or window manager you're using, I can offer some advice about how to edit your VNC configuration.  It may be easy (anything but Gnome) or not so easy (with Gnome).
