I installed VirtualBox on my Ubuntu 6.10 notebook. The install went smooth and I used the wizard to create the virtual hardddrive . I told it it was going to be XP, named it and gave it some memory which created a fixed .VDI file.
When I run VirtualBox I get the following error message:

robb@WS4313:~$ sudo VirtualBox
Password:
Qt WARNING: X Error: BadDevice, invalid or uninitialized input device 157
Major opcode: 145
Minor opcode: 3
Resource id: 0x0
Qt WARNING: Failed to open device
Qt WARNING: X Error: BadDevice, invalid or uninitialized input device 157
Major opcode: 145
Minor opcode: 3
Resource id: 0x0
Qt WARNING: Failed to open device

At this point the program starts but when I click on "Start" so that I can install the guest OS the machine does a hard reboot.

Any assistance would be greatly appreciated.

Thanks,

The VirtualBox command does not have to be run with su or sudo. Did you start the daemon first?

Dracolich, I was starting VirtualBox with sudo because when I started it as a normal user I would get those error messages and nothing else. At least as sudo the program would start, except that when I hit "Start" it would reboot the system. Since then I have uninstalled and reinstalled a couple of times and the latest and greatest version has come out which I used.
VirtualBox now starts with a normal user and I have installed XP and all is right with the world. As far as I know I did everything the same on the last install as the earlier ones but this time it worked.
Thanks for you assist
