VirtualBox - remote X11 console

Hi, since yesterday I have a weird problem. I cannot display VirtualBox _guest_ consoles remotely anymore (the GUI for configuration works). I am running Virtualbox headless on a server but use the GUI for installs when needed. I forward ssh (-X) and use "su -m" to keep the DISPLAY environment variable(DISPLAY=localhost:10.0) and xauth. Two weeks ago I did just that, 1. started "VirtualBox", 2. created a VM and a disk, 3. attached an ISO disk 4. pressed start and the "BIOS" appeared Yesterday it all goes up to step 3- just 4 does not work. I get an error instead of the BIOS screen, and on the server I get: X11 connection rejected because of wrong authentication. I checked all variables and parts - nothing has changed since the last install that worked a fortnight ago. Same kernel, same VirtualBox, same xauth, same desktop. The server is a recent FreeBSD 10, the desktop Oracle Linux 6.5. Do you have any ideas what could go wrong? Thanks for ideas Peter

Try running a simpler X client, e.g. xhost or xterm. To me it sounds like there is a low level X issue that has nothing to do with VirtualBox, and this is one way to find out for sure. Are you sure that DISPLAY is correct? It will change for every ssh connection. It won't always be localhost:10.0 -- Brian May <brian@microcomaustralia.com.au>
