I've been using this suspend hook with Ubuntu & Kubuntu since the days of 12.10, however when I did a clean install of Xubuntu 15.04 yesterday, I noticed it suddenly not working. I've created a file
/usr/lib/pm-utils/sleep.d/45fixusbwakeup copied the script into it, and made it executable with
sudo chmod +x /usr/lib/pm-utils/sleep.d/45fixusbwakeup as I always did before. I'm not an expert, and this hook has always been working from me, so I don't have a clue what could be wrong now.
What I basically need is that these 3 commands execute every time before computer is going to sleep, or at every startup:
sudo -s echo USB0 > /proc/acpi/wakeup echo USB2 > /proc/acpi/wakeup
I would also like to note that when I suspend via terminal command
sudo pm-suspend the script works flawlessly, it's only not working via traditional logout--->suspend button in Xubuntu, so I guess this is something Xubuntu-related. I guess it actually suspends via
xfce4-session-logout --suspend and that's creating the problem.
