I apologize for such a lengthy message but it's the one I posted to ubuntuforums. As the subject states I've lost my GUI apparently because the machine can't connect to X. Here's what I sent and I thank any and all in advance! Just to clarify, I updated some normal updates as prompted by Update Manager about 3 days ago. I'm 16.04 and they were normal security updates. Now when I boot the machine starts in graphic mode as (all hand typed and a real pain in the a**!) [CODE]ubuntu-laptop login:[/CODE] and I can log in as myself (ubuntu) [CODE]ubuntu-laptop login: ubuntu[/CODE] [CODE]Password[/CODE] then I try, which has always worked, [CODE]ubuntu@ubuntu-laptop: ~$ startx[/CODE] returns [CODE]X.Org X Server 1.18.4 Release Date 2016-07-19 X Protocol Version 11, Revision 0 Build Operating System: Linux 4.4.0-97-generic x86_64 Ubuntu Current Operating System: Linux ubuntu-laptop 4.4.0-117-generic #141-Ubuntu SMP Tue Mar 13 11:58:07 UTC 2018 x86_64 Kernel command line: BOOT_IMAGE=/boot/vmlinuz-4.4.0-117-generic root=UUID=ea9f5446-2b36-4ba1-bcfs-ac786107fd58 ro vga=792 quiet splash acpi_osi=Linux vt.handoff=7 Build Date: 13 October 2017 01:57:05PM xorg-server 2:1.18.4-0ubuntu0.7 Current version of pixman: 0.33.6 Before reporting problems check http://wiki.x.org to make sure you have the latest version Markers: [I]various symbols[I] (==) Log file: "home/ubuntu/.localshare/xorg/Xorg.1.log" time, (current time) (==) Using system config directory "/usr/share/X11/xorg.conf.d" waiting for X server to shut down (II) server terminated successfully (0).

However, I have a guest user that starts lightdm all by itself if I (ctrl+alt+f7) I can switch to my user in a terminal but the desktop remains lightdm and as guest. Some apps run, like libreoffice, and most do not like firefox, thunderbird, synaptic
