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.

Hi there :slight_smile:

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:
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:
