Package: acpi-support
Version: 0.109-10
Severity: important
Many /etc/acpi/*.sh scripts try to get the current X user by reading
display numbers in /tmp/.X11-unix/* and then then calling the getXuser
function (defined in /usr/share/acpi-support/power-funcs), that tries to
find the X user by looking at the output of the 'w' command.
Files in /tmp/.X11-unix are in this format:
t...@moth:~$ ls /tmp/.X11-unix/*
/tmp/.X11-unix/X0
Let's follow a script to see where the problem is. In /etc/acpi/lid.sh
we have this loop:
for x in /tmp/.X11-unix/*; do
displaynum=`echo $x | sed s#/tmp/.X11-unix/X##`
getXuser;
and, as I have only /tmp/.X11-unix/X0, the loop runs only once, with the
variable $displaynum set to '0'. Let's see what getXuser does.
user=`w -hs | awk '{ if ($3 == ":'$displaynum'" || $2 ==
":'$displaynum'" ) { print $1; exit; } }'`
It compares the 3rd and 2nd field of the output of 'w -hs' with
":$displaynum". But that's wrong! $displaynum is '0':
t...@moth:~$ echo $displaynum
0
but 'w -hs' reports ":0.0" in its 3rd (relevant) field!
t...@moth:~$ w -hs
torn pts/0 :0.0 30:04m -bash
torn pts/1 :0.0 1:24m -bash
....
The check always fails and the X user is not reported.
