Hello Christian,
Thanks. There were some errors applying the patch, so it wasn't fully
applied (see below). Of course, I'm using 5.13.2, not 5.14, so maybe
that's expected.
The patched 5.13.2 kernel still results in a blank screen while trying
to run wdm. On this attempt, wdm has died (oddly the screen remains
blank; it should display a text login after X dies). The Xorg.0.log
looks reasonable enough.
I tried disabling wdm, then rebooted, logged in at the console and ran
"startx". The screen goes blank, X is running, startx is running:
johnson 1392 0.0 0.2 2572 1452 tty1 S+ 08:06 0:00 /bin/sh
/usr/bin/startx
johnson 1414 0.0 0.4 4904 2096 tty1 S+ 08:06 0:00 xinit
/etc/X11/xinit/xinitrc -- /etc/X11/xinit/xserverrc :0 vt1 -keeptty -auth
/tmp/serverauth.dJ7lSnzjjo
johnson 1415 1.0 8.2 128436 41924 tty1 Sl 08:06 0:04
/usr/lib/xorg/Xorg -nolisten tcp :0 vt1 -keeptty -auth
/tmp/serverauth.dJ7lSnzjjo
I had to use "kill -KILL" to kill the startx, xinit and Xorg processes.
After those were killed, the screen was still blank, and even though
nothing was running, the load average was still around 1.00 several
minutes later, so something is still taking CPU time:
$ uptime
08:25:15 up 20 min, 2 users, load average: 1.00, 1.00, 0.84
I can attempt a git bisect, though that will take some time.
