Assunto: [DNG] Partial graphics after in-place upgrade from Ascii to Beowulf on amd64
Perhaps there is an installer image for Beowulf somewhere and this can
be solved with a fresh re-installation? Sunday, I did an in-place
upgrade from Ascii to Beowulf on amd64. I have only partial graphics
since and must get past some problems with (I think) X11.

When I allow slim, lightdm, or xdm one at a time (removing the others)
to start, the keyboard and mouse do not respond not even to switch to
a console even though they cause the display to show the graphical
login screen. However, when I disable / remove these display managers
then startx gives some lip about modules not existing.

When I run startx manually from a console, something similar happens
though I get a blank graphical display with the unmovable mouse
pointer centered on the screen. But the window manager seems not to
be running nor the desktop environment and, again, both the keyboard
and the mouse are unresponsive so timeout is a way to get it to drop
back to the shell.

$ timeout 15 startx
