my dirty hack for suspend/hibernate at kdm login screen


The only way I've found to get hibernate, and suspend to work at KDM is to add two 'sessions' to the session selector menu.

That is, where you select KDE, XFCE, etc.

Having sudo set up properly for the respective user accounts you wish to invoke the suspend/hibernate will then allow the suspend, and hibernate to be selected as your session, then you just enter your username and pass as you would normally do to login, and the pc will suspend or hibernate accordingly.

Just add the two desktop entries in /usr/share/apps/kdm/sessions

I named mine suspend.desktop and hibernate.desktop accordingly.

If you don't want to reboot, I'd just telinit 3 ; telinit 4 from ctl-alt-f6 and KDM should see them (logout and save work first . I don't think update-desktop-database' is needed iirc.

If anyone knows a better way, I *truly* am all ears. Especially if someone knows a good keybind, such as the ctrl-alt-del listed in Slackware's init scripts.

Happy Slackin'.

That's a pretty decent solution - back when I was trying to use kdm, I had just hacked the command used for halt instead

I still prefer gdm, and I made the version at SlackBuilds.org offer the Suspend option out of the box :-)

Looks ok and simple. Doesn't being part of the "power" group alleviate the need of having to su sudio those commands though? I never use hibernate/suspend so I don't really know.

If I understand it correctly (and I could be wrong) the hibernate/suspend actions you use when you use a tray icon in KDE, or xfce, which make a call via dbus to pm-suspend/hibernate etc., so yes the power group comes into play.

But if you call the commands on the command line, which is what the desktop files are in essence doing, then you'd need sudo.

You'll note the perm's on the below items:

ls -al /usr/sbin/pm*

lrwxrwxrwx 1 root root 31 2009-12-12 10:21 /usr/sbin/pm-hibernate -> /usr/lib/pm-utils/bin/pm-action
-rwxr-xr-x 1 root root 1568 2009-06-09 19:32 /usr/sbin/pm-powersave
lrwxrwxrwx 1 root root 31 2009-12-12 10:21 /usr/sbin/pm-suspend -> /usr/lib/pm-utils/bin/pm-action
lrwxrwxrwx 1 root root 31 2009-12-12 10:21 /usr/sbin/pm-suspend-hybrid -> /usr/lib/pm-utils/bin/pm-action
