howudodatI have a problem that is going to be the death of me :).  Converted the wife and kids desktop to ubuntu 16.04 and gnome 3.20.  I cant figure out how to set up a "reliable" multi user setup.  All the accounts are setup.  GDM fires up and then the nightmare begins.  First problem is how to switch users without logging out?  Next problem, I installed fast user switch widget, and updated the metadata so it runs on 3.20.  That works14:23
howudodatabout 20% of the time.  Sometimes it switches to a black screen.  Sometimes it switches to the user greeter, sometimes it does nothing.  I did a google search and a lot of the information I found was for much older versions of gnome ~3.6.  I dont necessarily want to do VT switching and have them log in using VT1/2 and switch with CTR-ALT-F#.14:23
jbichahowudodat: that's a good question15:33
jbichayou can lock the screen either with Windows+L or by clicking the lock button in the menu in the top right of the screen15:34
jbichaand on the unlock screen you can click Log in as another user15:35
howudodatjbicha: when I do that and I click on the "Logon as another user" it simply re-activates the curtain.  When I hit enter, I get back to the greeter.  Click on "Logon as another user" back to curtain.  wash->rinse-repeat15:36
howudodatworks about 10% of the time or less.   When it works, I am presented with a list of the 3 users, and I can switch.  But mostly it does the curtain lock, repeat loop I described above15:37
jbichahmm, it works for me15:40
howudodatjust did some typical windows style testing (involving multiple reboots)  it appears to work after a reboot for random N times.  then goes into la la land.15:51
howudodatok, so it appears that when it goes bad, parts of gnome-session are die-ing.  here are the errors I get16:09
