VNC only works with monitor connected
Last modified: 2008-08-20 11:20:46 UTC
I'm setting up a NFS server and want it to run without monitor, keyboard, mouse attached. Administration shall take place via VNC, This works just fine.... as long as I have a monitor attached. As soon as I start up the machine without a monitor on it the XServer fails (giving nasty error messages when I attach a monitor again) and VNC will only give me a grey checkered background. Video chip is Intel 945G. I've tried switching off monitor detection via Sax2 and in the xorg.conf ("NoDDC" and the like) but with no luck. I think it should work out of the box, otherwise it doesn't make much sense to have a VNC-switch in Yast. And it's probably not uncommon to run a machine with a cheap onboard graphic that's supposed to run without a monitor anyway.... - Martin Hildebrandt
You don't need any hardware - neither a graphics card nor a monitor - to run Xvnc. This report is INVALID. Looks like you're trying to use the VNC Xserver module together with a regular Xserver hardware configuration. This is not recommended (unsecure!) and not a supported scenario. Since openSUSE 11.0 SaX2 no longer creates a configuration for it. Maybe I finally need to remove the VNC module from the openSUSE distribution. :-(

It´s the scenario that the installation produces automatically when I switch on "remote administration" while installing. It´s been working this way for a lot of years and it would be a real disadvantage if it wouldn´t work anymore.... - MHi

You are wrong. YaST enables the start of Xvnc, when connecting the machine with a VNC client. This is completely unrelated to the VNC Xserver module.

I can´t tell you, if it´s technically related. From a users point of view I can tell you the following: I´ve just taken a machine with Suse 11.0 on it (clean install, no gadgets, nothing done on it so far) went to Yast2 and switched on remote administration. That´s all. After rebooting I can access the machine via http://192.168.161.50:5801 as long as a monitor is connected. When I reboot the (server) machine without a monitor, the same page being accessed from another PC in the same network while only give me a grey screen. I don´t really mind if it´s unsecure. I´m only using it in an internal network and there´s nothing really valuable on it. But I would sure like it to work the same way it did under 10.1 i.e.. - MHi
