Have you tried disabling power management via GRUB options? http://askubuntu.com/a/130541
Mike, thanks! You gave me good enough push into right direction, thanks to which I solved my problem.
Disabling power management via GRUB (boot) options didn't help me. I went further along these lines, tried to tweak related stuff in /etc/systemd/login.conf (systemd experts will probably lough, I'm not one, so... ;-) - didn't help either. I finally came to doing what helped me: edited
/usr/share/polkit-1/actions/org.freedesktop.login1.policy
(replaced "yes" with "no" in a few related places). This solved my problem. I'm not posting what exactly I changed, as I overdid it (disabled locally logged in user's ability to reboot/poweroff machine, and the same from gdm loging screen - I will need to restore these).
Thanks! Valeri
Be aware that the file /usr/share/polkit-1/actions/org.freedesktop.login1.policy is not a configfile and will be silently overwritten when systemd is upgraded.
In earlier releases of PolicyLit local changes were made in /etc/polkit-1/localauthority, but I don't know if that approach still works.
its long time ago but some EL6 workstation have here:
$ cat /etc/polkit-1/localauthority/50-local.d/10-disable-hibernate.pkla [Disable suspend] Identity=unix-group:* Action=org.freedesktop.devicekit.power.hibernate ResultAny=no ResultInactive=no ResultActive=no
Thanks Leon and Liam! You finally set me straight. All works, and other local user abilities stay intact (user can power of or reboot machine, the same can be done from gdm login screen). What finally worked for me (without fear to be overwritten with update) is the following. As you said, I edited (created new) file:
/etc/polkit-1/localauthority/50-local.d/10-disable-hibernate.pkla
This is what I put in it:
[Disable suspend] Identity=unix-group:* #Action=org.freedesktop.devicekit.power.hibernate Action=org.freedesktop.login1.inhibit-handle-suspend-key ResultAny=no ResultInactive=no ResultActive=no
[Disable suspend2] Identity=unix-group:* Action=org.freedesktop.login1.inhibit-handle-hibernate-key ResultAny=no ResultInactive=no ResultActive=no
[Disable suspend3] Identity=unix-group:* Action=org.freedesktop.login1.suspend ResultAny=no ResultInactive=no ResultActive=no
[Disable suspend4] Identity=unix-group:* Action=org.freedesktop.login1.suspend-multiple-sessions ResultAny=no ResultInactive=no ResultActive=no
[Disable suspend5] Identity=unix-group:* Action=org.freedesktop.login1.hibernate ResultAny=no ResultInactive=no ResultActive=no
[Disable suspend6] Identity=unix-group:* Action=org.freedesktop.login1.hibernate-multiple-sessions ResultAny=no ResultInactive=no ResultActive=no
As they say: you don't need to know everything, you only need to know right person you can ask ;-)
Thanks again, everybody!
