Disable Shotdown/Reboot/Hibernate buttons on LOGIN SCREEN

[WlaadDyaab]

anybody ideas? i don't want to remove the GUI completely, but if i can't find a fix for this i will have to.

Have you tried to right-click on the red shutdown icon, then choosing "Remove From Panel"

Or is your problem worse?

(And if you want to get it back you just right-click on the panel . Add to Panel... Then click on the "shutdown" icon and choose "Add")

It restarted GDM itself (service gdm restart) and the whole machine too. After each new input. But nothing helped till yet.

Thanks. May it be that those command structure works?:

Hey, sorry to tell you that, but this doesn't work either.
the mandatory thing i tried before, but this config is just ignored. is there a way to check what config-variables(if there are such) are loaded and user by gdm/gnome?
PS: i've executed the commands also as root and as user gdm (via su). doesn't make any difference to the login screen.

I just yet tested it myself and it works for me. Even without the mandatory thing, my steps were:

- enter those command in a terminal:

gksudo -u gdm dbus-launch gconf-editor

- enter the password, obviously
- browse down the path in the GUI to "/apps/gdm/simple-greeter/disable_restart_buttons"
- tick it
- close apps, logout
- press Ctrl+Alt+F1
- login at the console (if not already)
- enter those commands:

sudo service gdm stop
sudo service gdm start

(Yeah, "restart" may do it also.)

EDIT: You didn't mention it so far, which version of Ubuntu do you run?

[Blowfish0815]

except for the dbus-launch i did it exact the same and it is ticked since days...i have also unticked it and reticked it. doesn't change anything.

its ubuntu 10.10

Linux version 2.6.35-27-server (buildd@crested) (gcc version 4.4.5 (Ubuntu/Linaro 4.4.4-14ubuntu5) ) #48-Ubuntu SMP Tue Feb 22 21:53:16 UTC 2011

Maybe there is a change/bug in Maverick's GDM version, would not be the only one.

The only remaining option I can offer right now is to try to downgrade to Lucid's GDM version, but that may not work because of the dependencies:

i think i will remove gnome completely. i can run GUI programs also with x11-forwarding on my win-client with xming.
but thanks for trying.

I would also like an answer to this question. I am running two servers: one with 10.04 and one with 10.10.

I've only been trying to remove the menu with Shutdown/Restart/Hibernate on the machine running 10.10 so far, with no luck. Krytarik's suggestion of

gksudo -u gdm dbus-launch gconf-editor

does nothing, even after a complete reboot. Before being able to run the above, I also had to add user gdm to the users allowed to connect to the X server with:

xhost +SI:localuser:gdm

But the menu in the lower right corner of the login screen is still there. Surely there must be a way to remove it??!

I've also tried putting the following lines in /etc/gdm/custom.conf, without success:

RebootCommand=
ShutdownCommand=

Are there any other ideas? I've tried everything else in this thread, and in the others I could find.

Thanks!

Yeah, in 10.10 you need to run those command before the other will work. I forgot to mention that, sorry.
