Subject: acpid: lid.sh fails to turn off display
Package: acpid
Version: 1.0.8-1lenny1
Severity: important
/etc/acpi/lid.sh fails to turn off the display when lid is closed. lid.sh calls
/usr/share/acpi-support/screenblank.
ultimately, the command is xset dpms force off. display is determined by
environment variable. However, it was failing. I added an strace and determined
xset is unable to get permissions to connect to display, failing to access
/.Xauthority. I can make it work a number of ways, such as su - -c "(xset dpms
force off)" and generating an Xauthority for root, or su $user -c "(xset dpms
force off)" as is earlier in the same script for xscreensaver locking.
I am using a Dell Latitude D630 laptop. I run either fluxbox or awesome WMs
(fails in both).
I'm attaching my strace.
