[ltp] lenovo-lockbtn:cannot connect to X server

[Qiuye Wang]

Hello list,

i want to use the Fn+F2 to lock my screen, and because the default
lockbtn.sh in /etc/acpi does nothing (which uses acpi_fakekey
$KEY_COFFEE), i put the following in lockbtn.sh:
#!/bin/sh
kdesktop_lock --forcelock

and i got "cannot connect to X server" in /var/log/acpid.
although if i direct run the script and it works.

so, could anyone please help?
Thanks in advance

QY
