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?
