@george can you please upload updated image to onedrive as well. I cannot download from baidu.

Meanwhile one can pin PPA to prevent upgrades:

$ cat /etc/apt/preferences.d/coolpi-ppa-priority         
Package: *
Pin: release o=LP-PPA-george-coolpi-mali-g610
Pin-Priority: 2000

Package: *
Pin: release o=LP-PPA-george-coolpi-multimedia
Pin-Priority: 2000

Package: *
Pin: release o=LP-PPA-george-coolpi-rknpu
Pin-Priority: 2000

These packages come with latest update, when installed they break hardware acceleration:

libegl-mesa0/jammy-updates 23.2.1-1ubuntu3.1~22.04.2 arm64 [upgradable from: 23.0.5-0ubuntu1~22.04.1]

in order to get hardware acceleration back, one can downgrade by installing the packages from george's PPA:

apt-get install libgbm-dev:arm64=23.0.5-0ubuntu1~22.04.1 libegl-mesa0:arm64=23.0.5-0ubuntu1~22.04.1 libgbm1:arm64=23.0.5-0ubuntu1~22.04.1 libgl1-mesa-dri:arm64=23.0.5-0ubuntu1~22.04.1 libglx-mesa0:arm64=23.0.5-0ubuntu1~22.04.1 libglapi-mesa:arm64=23.0.5-0ubuntu1~22.04.1 libegl1-mesa-dev:arm64=23.0.5-0ubuntu1~22.04.1 mesa-va-drivers:arm64=23.0.5-0ubuntu1~22.04.1 mesa-vdpau-drivers:arm64=23.0.5-0ubuntu1~22.04.1 mesa-vulkan-drivers:arm64=23.0.5-0ubuntu1~22.04.1

Any plans to update PPA?

@george got it, thanks! Looking forward for proper wiring solution. Meanwhile, I'll try to put together some custom wiring.

I am very happy with the product performance and overall experience, but I would like to upgrade the screen to some better one, maybe 2K. Is it possible to do manually? If yes, which panel would you recommend to use. Does the laptop use standard eDP connector or something special? Are hardware/drivers capable of driving high resolution screens?
Thanks in advance.
