[Pkg-xfce-devel] Bug#780025: dm-tool: lock locks a new VT instead of current VT

[Ben Armstrong]

Package: lightdm
Version: 1.10.3-3
Severity: normal

I wanted to use dm-tool to debug a problem I'm having (lxpanel > "Lock
screen" does not lock the screen, which I will report separately on that
package) so I tried "dm-tool lock" to verify if locking works at all.
Unfortunately, instead of locking the current VT (vt7), it opened a new
one and locked it instead (vt8).

After locking, I pressed ctrl-alt-f7 to return to vt7 and observed it
was still unlocked, then pressed ctrl-alt-f8 and entered my password to
unlock vt8. Upon unlocking, I was switched back to vt7.
