I have PC with Debian 9 "stretch" x86_64 + Xfce and I never needed to have pm-utils installed, but hibernation\suspend feature works normally through xfce4 GUI once I set up all prerequisites for hibernation to work (such as at least working swap and initramfs resume variable). I also removed packages such as "uswsusp", "hibernate". I have used them previously, but now they are unnecessary for hibernation to work on my computer.
How you start Xfce DE and did you installed "xfce4-power-manager" package? You've said hibernation works when you trigger it manually, so check if hibernation works via systemd: $ systemctl hibernate On 18.10.2017 18:26, Pétùr wrote: > On my computer (Debian sid), with a nvidia graphical card and the 340 > proprietary driver, suspend/hibernate does not work with xfce tools. > > I means that xfce4-session-logout --suspend does not work for example. > > But pm-suspend or pm-hibernate works perfectly. > > And I can launch them as user because I edited my /etc/sudoers file with: > > my_user ALL = NOPASSWD: /usr/sbin/pm-hibernate > my_user ALL = NOPASSWD: /usr/sbin/pm-suspend > > So I would like to make pm-utils tools the default ones for > suspend/hibernate in Xfce. pm-utils commands should be triggered when > clicking "suspend/hibernate" on the xfce logout window. > > How can I do that? > -- With kindest regards, Alexander. ⢀⣴⠾⠻⢶⣦⠀ ⣾⠁⢠⠒⠀⣿⡁ Debian - The universal operating system ⢿⡄⠘⠷⠚⠋⠀ https://www.debian.org ⠈⠳⣄⠀⠀⠀⠀
