Comment 4 for bug 1797079

Sadly, there are no plans to change how light-locker works, so this will remain a known limitation.

The Xubuntu devs are currently creating a screen locker for the Xfce project (xfce4-screensaver). It will not rely on VT switching while still offering a nice look and feel. Future Xubuntu and Ubuntu Studio releases will most likely use this new locker instead.
