I didn't, :-( Thank you. Now to see if it works. :) Nope Here is a typical attempt to run synaptic-pkexec while logged in as 1st user, pi, on the r-pi from here: ------------ pi@raspberrypi:~ $ synaptic-pkexec ==== AUTHENTICATING FOR com.ubuntu.pkexec.synaptic === Authentication is required to run the Synaptic Package Manager Authenticating as: root Password: polkit-agent-helper-1: pam_authenticate failed: Authentication failure ==== AUTHENTICATION FAILED === Error executing command as another user: Not authorized ---------------- Which should have run it, exporting its x stuff to here. linuxcnc, geany etc all work just fine. This would appear to be a bug, one that the reboot command also suffers from. starting x on the r-pi was a disaster, unusable 4 color at max screen, text piled on top of itself too, so while its installed now, I am back the the vt1 login and work screen which works well. At one point last evening I discovered that the keyboards poor response was somehow, and randomly related to the boot. One reboot came up horrible, and it had been working pretty good, so I rebooted again, keyboard good. So I started rebooting it just for S&G's, random, but working well Most of the time. I should note that if the local keyboard is doofy, so is the remote keyboard IF you can even get logged in, most of the time you can't. I detest the use of the power plug to reboot it, the possibility of the sd card being trashed is quite real. However, amanda did get a good backup of it last night, hoooray! I wonder, could it be possible to setup a key combo alias in .bashrc, which would issue the reboot command so it would do a clean shutdown? But that would need it to work well enough to type ones sudo pw.

Its even been known to stop me from going/doing something angels wouldn't do. Not always mind you, but I survived.
