<pre>Same problem here on my Ideapad 330
Machine: Type: Laptop System: LENOVO product: 81D2 v: Lenovo ideapad
330-15ARR serial: <root required>
Mobo: LENOVO model: LNVNB161216 v: SDK0J40709 WIN serial: <root
required> UEFI: LENOVO v: 7VCN47WW date: 04/25/2019
Graphics: Device-1: AMD Raven Ridge [Radeon Vega Series / Radeon Vega Mobile
Series] driver: amdgpu v: kernel
Display: server: X.org 1.20.4 driver: amdgpu,ati unloaded:
fbdev,modesetting,vesa tty: 211x40
I have not used suspend. Lightdm starts without problem.
Cinnamon is working fine but XFCE4 ends up with that kernel oops and black
screen.
I have found out, that the compositor in xfwm4 is the culprint, if i disable
that compositor, xfce is running fine. Even if i use compton as compositor,
xfce is starting fine.
Then i also reveted

and now xfce is running without problem/black screen with internal compositor
activated.</pre>
