How to fix Resolution and Shutdown freezes issue on POP OS/UBUNTU 20

1. Type the following command:

sudo gedit /etc/default/grub

2. To fix shutdown freezing issue, please add below line to /etc/default/grub file:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=force"

3. To fix the resolution issue, add below line to the same file:

GRUB_GFXMODE=1024x768

You can change resolution to suit better your needs, in my case i was using a 1024x768 monitor.

After changing /etc/default/grub file you should update grub with the following command:

sudo update-grub

And then restart your computer.

How to fix Ethernet not working issue on POP OS/UBUNTU 20

In a terminal, type the following commands:

sudo echo "options forcedeth msi=0 msix=0" | sudo tee /etc/modprobe.d/forcedeth_options.conf

And then type:

sudo update-initramfs -u

Restart your computer and ethernet should be working normally.

Observations:

• Forcedeth is a generic ethernet driver that needs to be loaded to make ethernet worl properly.

• I am using a ASROCK MOTHERBOARD with a MCP61 (rev 2) Ethernet onboard device with a AMD FX-6300 six core processor 3.5ghz.
