[Pkg-acpi-devel] Bug#755172: acpi-support: combination of suspend and screen locking broken with xtrlock

[Lars Stoltenow]

Package: acpi-support
Version: 0.142-1
Severity: normal

When using xtrlock for screen locking, the screenblank script does not work
properly: The screen is locked, however, suspend is not initiated. After
entering password and unlocking the screen, the system is immediately
suspended.

This is probably because the /usr/share/acpi-support/screenblank script
does not invoke xtrlock in background. Because xtrlock (unlike the other
screensaver commands) blocks and does not return until the password is entered,
the /etc/acpi/sleep_suspend.sh only executes pm-suspend after the screen has
been unlocked again.

Proposed fix: Something like

                        su $XUSER -s /bin/sh -c "/usr/bin/xtrlock &"

in the screenblank script.
