glmark 1500 fps
sound works
Ubuntu not configured out from box - awesome

Mu laptop have a second life now

@plumlis
glmark2
stock ubuntu, linux kernel 5.1 - 2000fps (panfork ??)
debian testing, linux kernel 6.1 - 1000fps (panthor ??)
software - 150 fps (cpu ??)

With any GPU acceleration it's good.

Performance it's a second problem, first is - OpenGL ES 3.1
Good apps want open GL 4.5, example is blender or xonotic game.

@george
Thans! It is working!

gpu acceleration

sudo dmesg | grep panthor
create folder before copy
sudo cp /usr/lib/firmware/mali_csffw.bin /usr/lib/firmware/arm/mali/arch10.8/

@nathan said in 6.1 Kernel GPU firmware update:

before I switched to Linux 6.1 LTS with Panthor + newer Mesa).

Do you have mali acceleartion in OS?

After a certain update, video acceleration broke. So I decided to update to 6.1

gpu acceleration

sudo dmesg | grep panthor
create folder before copy
sudo cp /usr/lib/firmware/mali_csffw.bin /usr/lib/firmware/arm/mali/arch10.8/

It's fix for sound thanks!

Comment out some alsa related in /etc/rc.local
Then boot into system. type alsamixer in terminal. F6 to select sound card.
Use " M" key to unmute left headphone mix and right headphone mix something like that. System is slow, because there is no hardware acceleartion.

And disabled this service wirh errors

sudo systemctl disable qrtr-ns

May be you cad add laptop here
