Colors look nice. GNOME and KDE night mode works fine as well. Some distros may require manual setup for the scaling. A 90 hz mode can be optionally enabled in the KDE systemsettings under Display Configuration.
Brightness adjustment keys work fine with kernel 5.13. Kernel 5.15 has issues with adjustment keys, see keyboard details below.
The touchscreen is an optional upgrade, that not all units come with. Multitouch works out of the box, even in UEFI.
Resolution is correctly detected by xrandr, 200% scaling was activated by default and looks good.
Some apps require custom adjustments for proper scaling. A few examples:
- sudo vim /var/lib/snapd/desktop/applications/spotify_spotify.desktop
- And then you change the Exec directive to include the option: Exec=env BAMF_DESKTOP_FILE_HINT=/var/lib/snapd/desktop/applications/spotify_spotify.desktop /snap/bin/spotify --force-device-scale-factor=2 %U
Steam has an (ongoing issue)[ValveSoftware/steam-for-linux#9209], that prevents it to start with an appropriately applied scale on high resolution displays. This is a known regression for a long time, and here is how you can circumvent that by creating a custom launcher.
On KDE:
Right click on the menu, and select Edit Applications and then find the Steam launcher. Add the following line to the field Commandline Options: -forcedesktopscaling 1.75 %U
On other systems, you can do this by creating a desktop file:
$EDITOR .local/share/applications/SteamScaled.desktop- Paste in the following text:
[Desktop Entry]
Name=Steam Scaled
Exec=env GDK_SCALE=2 steam
Type=Application
StartupNotify=true
Icon=steam
StartupWMClass=steam
Name[en_US]=Steam Scaled
Safe and exit.
- Make a backup: sudo cp -a /etc/default/grub /etc/default/grub.bak
- Open the configuration: sudo $EDITOR /etc/default/grub
- Edit GRUB_GFXMODE entry to suit your resolution e.g. 2880x1800
- sudo update-grub
- Reboot; GRUB will display in the mode you set.
Works as expected in Ubuntu 22.04, POP_OS 22.04. Works with 5 Ghz networks. For other versions some setup manipulations were required.
kernel 5.13
Works out of the box on Ubuntu 21.10 with kernel 5.13, as it already contains the required API changes.
kernel 5.15
Does not work with 5.15 kernel out of the box. Follow carefully the additional setup instructions to fix the wifi module.
Only 2 speakers out of 4 work. Open issue: #2

Some function buttons do not work: F9 (settings), Star S. Print Screen works only while Fn button is pressed. All the other functions including Fn lock, home, end, pg up, pg down work out of the box. 3 levels of keyboard light work as well.
Tested balanced mode for now. Battery life is approximately 5 hours.
You can find a separate page with additional tools for battery performance improvements.
All the 3 power modes in GNOME do change BIOS power modes settings.
todo: test power modes
It works with Howdy after enabling the IR-sensor with this: https://github.com/EmixamPP/linux-enable-ir-emitter
Install https://github.com/EmixamPP/linux-enable-ir-emitter:
git clone https://github.com/EmixamPP/linux-enable-ir-emitter.git
cd linux-enable-ir-emitter
sudo bash installer.sh install
sudo linux-enable-ir-emitter configure look at the ir emitter and answer no on the 1st question and yes on the 2nd question.
Install howdy on Ubuntu:
sudo add-apt-repository ppa:boltgolt/howdy
sudo apt update
sudo apt install howdy
sudo howdy config, set device_path to /dev/video0.
sudo howdy add follow the instructions
Reboot.
AMD P-State is enabled by default for all Linux kernels starting with version 6.3 and you can manually enable it with kernel 5.17+, as it is written in this ArchWiki page (about a similar model).
NOTE:
The OEM kernel in older Ubuntu version has this setting also enabled by default.
sudo apt install linux-image-5.17.0-1012-oem
