Thanks.

There are two points of interest in that log I can see:

Jan 29 09:45:01 test /usr/lib/gdm3/gdm-x-session[656]: (II) intel(0): resizing 
framebuffer to 2732x768
Jan 29 09:45:01 test /usr/lib/gdm3/gdm-x-session[656]: (II) intel(0): switch to 
mode [email protected] on LVDS1 using pipe 1, position (0, 0), rotation normal, 
reflection none
Jan 29 09:45:02 test /usr/lib/gdm3/gdm-x-session[656]: (II) intel(0): switch to 
mode [email protected] on VGA1 using pipe 0, position (1366, 0), rotation normal, 
reflection none

and

Jan 29 09:45:51 test gnome-shell[931]: Skipping layers 1..n of your
pipeline since the first layer is sliced. We don't currently support any
multi-texturing with sliced textures but assume layer 0 is the most
important to keep

Both of these suggest the problem is that gnome-shell is trying and
failing to render across two screens (2732x768) because the code that's
meant to handle that for older GPUs like this is not well tested (no
developers use that kind of hardware).

As a workaround
~~~~~~~~~~~~~~~
Please just unplug your second monitor and leave it unplugged. The system 
should work fine with just a single monitor. In fact, please reinstall again 
without ever plugging in that second monitor and everything should just work.

As a permanent fix
~~~~~~~~~~~~~~~~~~
I think this is probably one of the bugs that Gert van der Kraats has been 
working on recently: bug 1790525 or bug 1795774. The fix for those has only 
been in 19.04 for a couple of days so please try live booting 19.04 
(http://cdimages.ubuntu.com/daily-live/current/) and tell us if that seems to 
fix the problem.

  Description: lightweight GTK+ window manager
   Mutter is a small window manager, using GTK+ and Clutter to do
   everything.
   .
   Mutter is the clutter-based evolution of Metacity, which, as the
   author says, is a "Boring window manager for the adult in you. Many
   window managers are like Marshmallow Froot Loops; Metacity is like
   Cheerios."
   .
