Just another data point. I logged in as non-root, opened a terminal window, went to the /usr/lib/i386-linux-gnu/enlightenment/utils and executed
./enlightenment_sys halt and it worked. (./enlightenment_sys reboot worked also). So again, it appears that when I try to shutdown or reboot as non-root (when using entrance as the DM instead of lightdm), I don't get to the invocation of enlightenment_sys. In glancing at the code, I see there is a check for immortal windows. I don't really know if there is any possibility of immortal windows. Of course I would think I would hit the problem as root and/or when using lightdm as DM. Since the window gets blanked when I hit the shutdown or reboot button (either via the menu or the button on the widget), I have no way of knowing whether there is an immortal window or some other dialog showing up. Anyone have an idea if there could be something waiting to close, and if so, any way to know that? Or something else that would cause it to not complete? I can switch to a VT. Is there anything I could query? Thanks. -------- Original Message -------- Subject: Re: [E-devel] logout, reboot as non-root using entrance DM Date: Sat, 15 Mar 2014 11:43:00 -0400 From: Chris Seekamp <cseek...@acm.org> Reply-To: cseek...@acm.org To: Carsten Haitzler (The Rasterman) <ras...@rasterman.com>, Enlightenment developer list <enlightenment-devel@lists.sourceforge.net> So, interestingly, the enlightenment_sys did not have setuid set. I set it, but still saw the same behavior. When I try shutdown or reboot, this is what I see when I use ps and search for enlightenment: bodhi32 1226 1 0 09:30 ? 00:00:00 /bin/bash --login -c /usr/bin/enlightenment_start > /home/bodhi32/.entrance_session.log 2>&1 bodhi32 1231 1226 0 09:30 ? 00:00:00 /usr/bin/enlightenment_start bodhi32 1234 1 0 09:30 ? 00:00:00 dbus-launch --exit-with-session /usr/bin/enlightenment_start bodhi32 1236 1231 2 09:30 ? 00:00:01 /usr/bin/enlightenment bodhi32 1282 1236 0 09:30 ? 00:00:00 /usr/lib/i386-linux-gnu/enlightenment/utils/enlightenment_fm When I try logout, I see the following at the bottom of the enlightenment_start log: E19: Begin Shutdown Procedure! PKGKIT: dbus_shutdown() E - PID=1436, valgrind=0 But when I try shutdown or reboot I do not. Like I said, I see a black screen with a cursor, but enlightenment and X are still running. Just for grins, I tried adding a entry in sysactions.conf to allow the bodhi32 to do halt reboot suspend hibernate but it made no difference. I suspect it isn't getting as far as the enlightenment_sys call. BTW, when I used lightdm, I do see one additional reference to enlightenment when I use the ps command: /usr/bin/ssh-agent /usr/bin/dbus-launch --exit-with-session /usr/bin/enlightenment_start I don't know if that is significant or not. I believe this comes from /etc/X11/Xsession.options (the "use-ssh-agent" line). I don't know why lightdm has ssh-agent running but entrance doesn't. Also, the with lightdm I do not see: /bin/bash --login -c /usr/bin/enlightenment_start So perhaps the issue is how entrance launches X?
