Results of drm.debug=0x1e

Kernel version is latest xubuntu live CD 18.10, booted from a USB stick.

ubnkern: Linux kernel x86 boot executable bzImage, version 4.18.0-10-generic
(buildd at lcy01-amd64-023) #11-Ubuntu SMP Thu O, RO-rootFS, swap_dev 0x7, Normal
VGA

kernel parameters were drm.debug=0x1e log_buf_len=4M.  quiet and splash were
removed.

When I first booted the live CD image, The top bar, with at least some but not
all widgets appeared.  Half of the desktop appeared, but with holes.

<some messing around, trying to get log files off a live CD boot>

Second boot just gave a blank screen, with cursor at upper left.  I shut the
system down (Magic-R + ctrl-alt-F2 + shutdown now), and pulled the log files
out of casper-rw.

auth.log
faillog
gpu-manager.log
syslog
Xorg.0.log

The following *.out files were from a subsequent run.  This time I didn't add
the drm.debug parameter, but instead stopped at systemd.unit=rescue.target. 
Again, none of the desktop appeared after I resumed execution.  It just sat
there with the cursor at upper left.

lshw.out
lsmod.out
lspci.out
lsusb.out
modinfo.out
