halt and reboot not working as normal user after upgrade.

I was using "halt" and "reboot" commands as a normal user and it was fine until recent upgrade after changing to core from current. These commands need root privilage now.... I dont understand why. Please help.

Never use method with chmod, it's a HUGE security BUG. And I am really not paranoid, I have run into problems with this method.

Either use GDM and friends or sudo. I prefer the first method.

Re: halt and reboot not working as normal user after upgrade.

Also it is metod with /etc/inittab
Edit similar line there into:
ca::ctrlaltdel:/sbin/shutdown -t3 -h now
(I think you have only to replace r with h).
Then ctrl+alt+del calls shutdown.

+sry but GDM sucks. Usless waste of system power thats all from it.
Ppl disable it even on Ubuntu.
And sudo is not fun also.

Could you please explain the security issue with chmod, then the wiki can be edited according to that.

Re: halt and reboot not working as normal user after upgrade.

GDM really sucks.

inittab thing did not work for me, i dont know why..

Since i'm in sudo group, i can anyway shutdown using sudo command, but again it requires lot of typing and not a one key solution as early I added a key binding for "exec halt.

I guess chmod is the only best thing.

Re: halt and reboot not working as normal user after upgrade.

Chmod solution is tolerable as long as there are no remote logins to your system or the only people who can login remotly are especially trusted. When you chmod +s shutdown/ halt/reboot any user (also users logged remotely) can shut down your system (either maliciously or by mistyping).

Also SUID-ed programs are one of the easiest way to gain root privileges.

By saying 'GDM sucks' you mean that  you prefer KDM (or similar) or that you don't like any Display Manager and issue startx command after login?

Yes, i dont prefer any DM, just login on console and dont need to fire startx to start X. Just added this line in ~/.bash_profile file

ps ax|grep -q "[ ]`which X`" || exec xinit >/dev/null 2>&1

You could edit your sudoers file to allow you to run shutdown (or whatever command you use) with no password and then with a new keybinding it would be just as quick as before

Me personaly startx
And yes /etc/inittab method sometimes fails to work in gui. So ctl+alt+bckspace (stop gui) and only then clt+alt+del works just fine.
