After I upgraded to Tumbleweed 20191018, my gnome would load to a black screen
with a moving mouse cursor.

This is an nvidia optimus laptop using modesetting.

I tried deleting all the configs in my $HOME, including .local, .config and
.cache but the problem persisted.

I tried changing the invocation of gnome-session in my .xinitrc to
gnome-session -f to start a failsafe session, but it still went to a black
screen.

XFCE works fine when I run xfce4-session instead of gnome-session from my
.xinitrc.

Here is the journalctl output:
