I had Ubuntu 17.04 running on a spare desktop, DELL 7010 (12G RAM) x64.

Had been working fine, so when prompted to upgrade given other Ubuntu upgrades have gone fine - I OKed it.

Since the upgrade a few things are happening. The main one is I have few machines which I'm using KVM switch. The Ubuntu is acting like when I switch away, I've logged off. When I come back I'm at a login screen and when I sign in I have to restart all my applications. (Initially I thought it was maybe going a sleep).

I've check power settings - set to not go off. I turned off screen lock to see if that would make a difference. I set blank screen to NEVER.

When I look at the directory /var/crash - I see new files created. _usr_bin_gnome-shell.1000.crash _usr_lib_gnome-terminal_gnome-terminal-server.1000.crash

I looked at them, didn't mean a lot to me.

Happy to post the content but I thought I would ask if there is setting I've missed to start or it's a bigger problem. Tried doing some googling without much luck.

Running app wise when it stop: BOINC and Firefox normally. Maybe gimp. On 17.04 I had been running Conky but it didn't appear to be working in 17.10 and given my other problems I've not worried about it.

    I'm having the same issue, would appreciate any support with this as I need to switch between different computers on a regular basis and each time I lose all my unsaved work. – Mark Tyers Oct 27 '17 at 09:09

    Good to know I'm not the only one. I'm going to reimage my machine at this point as it's a test box and I can do that. Let you know if it works better vs the upgrade. – Stephen Christian Oct 31 '17 at 14:46
  • After the re-image: same result. Therefore it's not the upgrade but the full 17.10 appears to "log you off" if you switch away from the comptuer using the KVM-switch. I will continue to google to see if I can find a setting to "STOP" this. Otherwise I will have to downgrade to 17.04. – Stephen Christian Nov 01 '17 at 17:20
  • I next installed a 2nd keyboard and mouse (which we also working) but this didn't make a difference. I had hoped it was some sort of ground detection on them. I will try having a 2nd monitor to see if that solves it. – Stephen Christian Nov 02 '17 at 13:25
  • 2 monitor grounded – Stephen Christian Nov 02 '17 at 13:54
  • So far having a monitor "connected" not on and not using that input (seems - only been about 15m of testing) to fix the problem. The KVM is using the VGA port. I hooked up a display port to DVI cable and the DVI into 2nd (Could be the first but I was testing various thing like powering it off, keeping the video feed ON, having it sent to a different input). With that cable connected (even if the output is NOT displayed anywhere - but plugged in/grounded) The system does NOT log me off. – Stephen Christian Nov 02 '17 at 14:11
  • It seems that at least 2 guys have the same problem (https://bugzilla.gnome.org/show_bug.cgi?id=761352). The bug dates from 2016 but is still open, I think the best way to get it fixed is to ask for help there. It is also in the ubuntu bugs here : https://bugzilla.gnome.org/show_bug.cgi?id=761352 – pim Nov 02 '17 at 15:33
