The error message:
/etc/toolboxdaemon: error opening user interface device: No such device
may mean that your toolbox user interface device may be corrupted or may
have disappeared.
Check to see if the toolbox-specific device "/dev/uinter0" exists. The mode
of toolbox-specific device should be:
crw-rw-rw- 1 root sys 4, 0 May 3 16:30 /dev/uinter0
If this device file is corrupted or has disappeared, here is how to
recover:
1. Bring the system to the single-user mode.
2. In single-user mode, type the command
# /etc/newunix toolbox
3. Type the command
# /etc/autoconfig -u -v -o /unix -S /etc/startup
4. Type the commands:
# sync
# sync
# sync
7. Reboot with the command
# reboot
This should not happen in A/UX 2.0 and beyond.
