I have Ubuntu 19.04 OS installed on my Dell laptop. When I close the laptop lid and open it up to resume my work I end up seeing TOTAL WHITE SCREEN. I will have to power down and restart my laptop again after a few minutes for the luck to come by my side.

I get the below output when I run inxi -G in my command line:

Graphics:  Device-1: Intel Skylake GT2 [HD Graphics 520] driver: i915 v: kernel 
           Device-2: AMD Sun XT [Radeon HD 8670A/8670M/8690M / R5 M330 / M430 / R7 M520] driver: radeon v: kernel 
           Display: x11 server: X.Org 1.20.4 driver: radeon resolution: 1920x1080~60Hz 
           OpenGL: renderer: Mesa DRI Intel HD Graphics 520 (Skylake GT2) v: 4.5 Mesa 19.0.8 

When I run cat /proc/cmdline on terminal, I get:

BOOT_IMAGE=/boot/vmlinuz-5.0.0-27-generic root=UUID=c6435873-c6f7-440e-b4eb-f390052fa747 ro quiet splash vt.handoff=1

When I run sudo lshw -c video, I get:

When I run sudo lshw | grep -A5 "Moth" && lshw | grep product | head -n1 as superuser, I get the output below:

       description: Motherboard

    product: Inspiron 5559 (06B2)

When I run cat /etc/systemd/logind.conf | grep -i LidSwitch, I get:


My current display resolution: 1920 x 1080 with 60.00Hz refresh rate and 100% scale.

I would appreciate your help in resolving this issue.
