Ubuntu MATE 20.10 Display Problems

sorry if i posted this in the wrong place as it is my first time on this forum, and my english is not very good as i use translator.

I currently use Ubuntu 20.10 and I decided to install MATE on it, when I switch to the MATE desktop the screen looks very choppy, I thought it was Ubuntu's error and I decided to try Ubuntu MATE and installing it brought me the same surprise, before I tried ubuntu mate 18.04 lts and it worked perfect for me, but with the most recent version no longer, and I don't think it's a problem with ubuntu MATE but with the desktop, I use the HP 245 G6 Laptop (amd).

Again I apologize if I made a mistake about something.

Thanks

Hi Kevin, If you want to use 20.10, better you use 20.04 for more stable kernel.
On display problems you can try to edit grub.
Install Mate and then run on ubuntu-live usb if display shows broken image.
Edit this file:
/etc/default/grub
On this line, edit:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash amd_iommu=on"
On terminal, run sudo update-grub and reboot.
Now see if Ubuntu runs normaly with no display problems.

If not, you can repeat same procedure with different commands:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash amd_iommu=off"
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash amd_iommu=on iommu=pt"

Your laptop is not easy made for linux:

Cheers
