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
