In the olden days when dinosaurs roamed the earth 🙂 a trick used on headless systems was to make up a special VGA plug with a resistor across a couple of pins that did nothing but trick the computer in to thinking a monitor was still attached. While it might be possible with other VNC software to override the resolution and aspect ratio the speed will still suffer as detailed above.Īpple's reasoning presumably is that if there is no monitor connected then what is the point in enabling the video card since it cannot be displayed. It will also be much slower drawing the screen and this includes the speed of the VNC session because it is only running in software on the main CPU instead of in hardware on the GPU.

This will be a 4:3 aspect ratio and a fixed lower resolution.

If there is no monitor connected to the Mac or the monitor is turned off then the Mac will 'disable' the video card and emulate a basic lower spec video in software. Using another Vnc client is also possible (but again, if I can stick to the client I'm already using for years, I'd like that better). Using another Vnc Server is possible (but if possible with the internal one its even better). There does not seem to be much settings about the vnc server I the Mac so anybody an Idea on how to solve this? This is not really important but if I can have it fixed, why not. I have two widescreen displays so if necessary I use one fullscreen for the Linux or the Mac (but on the Mac I have two unused areas at the sides). Display size: as no display is connected the the Mac, it apparently assumes that it needs to be displayd in a 4:3 factor. Speed: the Vnc to the Mac is significantly slower than to the Linux (this is annoying, and I like to have it improved but if necessary I can live with it ). If I use Vnc viewer, the keyboard is a US style keyboard (I guess, but I can't say for sure as the flag at the top is still the correct one). I set up the Mac to use the keyboard without problems, when a keyboard was connected to it during initial setup. Keyboard: I use a 'none standard' keyboard. As OS X has a build in VNC server I thought this to be a piece of cake but I've run into some problems:

Now I have added a Mac Mini, which I would like to use the same way as the Linux. I use this linux using RealVnc viewer on my PC (works like a charm, ) There's no keyboard/mouse/display connected to the linux (only power and ethernet). are connected.Ī Linux PC (7 years old), that is connected to the same network as my PC. A Windows Desktop PC (my main PC) to which keyboard/mouse/displays.
