Hey there, sorry to hear you're stuck with this screen misalignment and flickering issue on your Huawei Matebook E 2021 after setting up Ubuntu 22.04. Given your 11th-gen Intel Xe integrated GPU, here are some targeted fixes that have resolved similar problems for other users:

1. Update to the Hardware Enablement (HWE) Kernel #

Ubuntu 22.04's default kernel might lack full support for newer 11th-gen Intel graphics. The HWE kernel brings updated hardware drivers and bug fixes tailored for newer devices:

• Open a terminal and run these commands:

  sudo apt update && sudo apt upgrade -y
  sudo apt install --install-recommends linux-generic-hwe-22.04 -y
  

• Reboot your laptop once the installation completes.

2. Tweak GRUB Boot Parameters for Intel GPU #

Flickering and screen misalignment often tie to Intel's Power Saving Refresh (PSR) feature or unrecognized display settings. Let's adjust the GRUB config to address this:

• Open the GRUB configuration file with a text editor:

  sudo nano /etc/default/grub
  

• Find the line starting with GRUB_CMDLINE_LINUX_DEFAULT and modify it to include these parameters:

  GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i915.enable_psr=0 video=eDP-1:1920x1200@60"
  

  • i915.enable_psr=0 disables PSR, a common culprit behind screen flickering on Intel Xe GPUs.
  • video=eDP-1:1920x1200@60 forces your display to use its native resolution and refresh rate (adjust the resolution value if your screen has a different spec).
• Save the file (press Ctrl+O, then hit Enter) and exit nano (Ctrl+X).
• Update GRUB to apply the changes:

  sudo update-grub
  

• Reboot your laptop to let the new settings take effect.

3. Manually Adjust Display Position #

If the screen is still offset, you can use xrandr to fix the alignment:

• First, identify your internal display name by running:

  xrandr
  

  Look for a line starting with eDP-1 (this is typically the built-in screen on laptops).
• Then, set the display position to the top-left corner with:

  xrandr --output eDP-1 --pos 0x0
  

• To make this change permanent, add the command to your startup applications: search for "Startup Applications" in Ubuntu's app menu, create a new entry, and paste the xrandr command into it.

4. Reinstall Intel Graphics Drivers #

Corrupted or missing graphics drivers can sometimes cause display glitches. Reinstall the official Intel drivers:

• Run this command in the terminal:

  sudo apt install --reinstall xserver-xorg-video-intel xserver-xorg-core -y
  

• Reboot your laptop after the reinstallation finishes.

If none of these steps work, you can also check for firmware updates—Ubuntu 22.04 includes fwupd by default. Run sudo fwupdmgr refresh && sudo fwupdmgr update to scan for and install hardware firmware patches that might resolve the issue.
