KDE 5 (sddm): cannot shut down or restart

jdkaye · 09-30-2015, 04:11 AM

I'm running Debian Testing (Stretch) with a KDE desktop. It has been a trying experience living through the transition from KDE4 to KDE5. I have plasma-workspace 4:5.4.1-1 and sddm 0.12.0-4 installed. My problem is that I cannot restart or shutdown from KDE in a normal way: going to the "Leave" menu from the Application launcher and selecting either Restart or Shut down from the System section of Leave.

Click on either one takes me to the SDDM login screen. If I try to restart or shut down from there I get a counter which counts down to 0 and then goes into negative numbers and would continue forever unless I cancel the operation.

I have two ways to shut down or restart KDE (besides simply turning off the computer:
a. I can log into Gnome Flashback Metacity from the login window and either restart or shut down from there. Interestingly, I get a dialogue box to enter the root password. I cannot do this with my normal user privileges as I did in the past.
b. I can Ctl-Alt-F1 to a tty, log in as root and give either the reboot or halt command.

So the problem seems to be that KDE now requires root privileges to either restart or shut down but does not provide the means to get these privileges.

Any pointers to the solution of this problem would be greatly appreciated.

Is your user member of the power group?

My user was not a member of the power group. I made the user (the only user on the system besides root) a member of the power group. This made absolutely no difference. I still cannot either shut down or reboot the computer from the KDE5 Leave menu as I explained in my first post. Let me emphasise that this is a NEW problem. I have been using KDE for over 10 years and I have never had this problem before. Up to now I had always been able to shut down or reboot the computer from the Leave menu. I guess that's why those options are there.

Did you tried to wipe the .kde folder in your home directory? (with a backup in case it doesn't work or if you want to troubleshoot)

I second this. I have 2 machines also running stretch KDE and as of last night, neither had an issue with shutting down as a user. But when the upgrade to 5 began, I purged all my kde configuration files in order to have a "clean" KDE5 config.

Thanks to both of you. I've wiped the .kde folder and will now log off and see if this works. Will report back the results.

Nope. No change in behaviour. This is definitely a system-wide problem. I discovered a seldom-used user account and tried rebooting from that account. The same result. It only took me to the login screen and would not go any further. On my own account, removing the .kde file had no effect on the problem whatsoever. I think there must be a system configuration file somewhere that was "upgraded" in KDE5 and now needs editing.

I tried this command and got this result:

Code:

~$ qdbus org.kde.ksmserver /KSMServer canShutdown
true

Very perplexing.

Just to test, I just did a dist-upgrade, and am able to log out, restart, and shut down from KDE 5 while using SDDM.

Just because of the oddities I've seen from it, are you by any chance using proprietary xorg drivers?

jdkaye · 10-02-2015, 01:00 AM

As far as I know the only proprietary drivers I'm using are for my Brother printer/scanner. Is there any command I could run to check? As I said, I'm pretty sure it's a permissions issue. If I log into Gnome Flashback Metacity then I can reboot or shut down but only after being prompted for my root password by a dialogue box. Note that no dialogue box appears when I try to shut down or reboot from KDE5.
