linuxmint - Run scripts on start or end of xsession -

i trying find way run script on sleep before x session ends, because script requires active x session execute properly. storing script in /etc/pm/sleep.d did not work (and returned errors related non-existent x session). ideas put script?

king@death-star /etc/acpi $ cat 01_revert_kb_on_sleep  #!/bin/bash touch ~/desktop/touchfile_my_script_acpi case "$1" in hibernate|suspend) sh -c "/home/king/desktop/scripts/rotate_desktop normal; /home/king/desktop/scripts/misc/my_keyboard on" 2> ~/desktop/revert_kb_error_log.txt ;; #thaw|resume)  king@death-star /etc/acpi $ ls total 1mb drwxr-xr-x   3 root root 1mb jun 11 23:36 . drwxr-xr-x 163 root root 1mb jun 11 23:41 .. -rwxr-xr-x   1 root root 1mb jun 11 23:36 01_revert_kb_on_sleep  king@death-star /etc/acpi $ ps -ef| grep acpid root      1070     1  0 23:41 ?        00:00:00 acpid -c /etc/acpi/events -s /var/run/acpid.socket king      3499  2574  0 23:52 pts/2    00:00:00 grep --colour=auto acpid 

step 1.

a. enable , start acpi service.

b. run acpi_listen command , try putting computer sleep via various methods (pushing power button, closing lid, etc.)

c. find out events triggered, when above. in case were: button/lid lid close , button/sleep sbtn 00000080 00000000

step 2.

a. create file /etc/acpi/events/my_events following:

event=(button/sleep sbtn|button/lid lid close) action=/etc/acpi/my_script.sh 

substitute events in event= line events.

b. create file /etc/acpi/my_script.sh following:

#!/bin/sh /home/king/desktop/scripts/rotate_desktop normal /home/king/desktop/scripts/misc/my_keyboard on 

nb. might need add export display=:0 before scripts access x session.

nb2: scripts run root user credentials. run user credentials, might want do:

sudo -u king /home/king/desktop/scripts/rotate_desktop normal sudo -u king /home/king/desktop/scripts/misc/my_keyboard on 

c. make file /etc/acpi/my_script.sh executable:

chmod +x /etc/acpi/my_script.sh 

d. restart acpi service.

step 3. share , enjoy.
