Yes ,rog ally too

Yes it work on arm cpu fine on my oneplus6 post market os I am watching freetube in flatpak

I was learning what they are actually and I don’t see any point of using linux-libre.Nowdays Linux kernel loading firmware for device from packages called “linux-firmware” technically is binary files located in ur filesystem.Linux libre project just removing mechanism of loading firmware dynamically,does it make device free? No they just don’t work.Devices which work with linux-libre for example WiFi dongles contains already firmware on WiFi chip itself and not loading from ur computer.In fact u even loosing security patches from vendors which u can get as updates for all devices.Linux libre project even removing warning about that u are u are using vulnerable firmware.Blobs which now located in kernel code itself is header files with some amount of arrays number arrays.Also not all firmware files works in once,kernel loading only needed one for hardware installed in computer right now So in conclusion I would not use such kernel,problem not in kernel ,problem that vendors don’t share source code for devices.Project linux libre not okay with dynamically loading firmware from filesystem buy they are okay with firmware which installed on devices which work without dynamically loading.It’s weird and sounds hypocrisy

About upscayl u maybe heard https://github.com/upscayl/upscayl

and denoise https://github.com/royerlab/aydin

U actually just removed part of hyperland environment ,system is fine actually ,u just need to switch to tty or using live system and chroot to install again package u removed and that’s it gonna work again.

I do not recommend using discover on arch because packakit-qt6 is borked and not working well for arch main repos,flatpak need to be installed manually as package but if u want so much using GUI for packages better try install pamac from aur,it’s niche GUI frontend for package manager from manjaro team which handle flatpaks usual packages and aur packages too

Usual plasma using bluedevil as frontend for Bluetooth does it installed? And what log saying in Bluetooth service sudo systemctl status bluetooth?

Please apply options for nvidia which i provided and install switcheroo-control (if u wonder it let dynamically set enviroment variables to use nvidia for ur running app example

[user@computer ~]$ switcherooctl  glxinfo | grep "OpenGL renderer"
OpenGL renderer string: NVIDIA GeForce 940MX/PCIe/SSE2

and if issue with brightness will persist let me know.

yeah it’s looks fine,it’s using igpu.Tell me also which version of nvidia driver u have in system.About parameters ,we tell to nvidia driver to

 NVreg_UsePageAttributeTable=1 (Default 0) - Activating the better memory
 management method (PAT). The PAT method creates a partition type table at a
 specific address mapped inside the register and utilizes the memory
 architecture and instruction set more efficiently and faster. If your system
 can support this feature, it should improve CPU performance.

 NVreg_InitializeSystemMemoryAllocations=0 (Default 1) - Disables clearing
 system memory allocation before using it for the GPU. Potentially improves
 performance, but at the cost of increased security risks. Write "options
 nvidia NVreg_InitializeSystemMemoryAllocations=1" in
 /etc/modprobe.d/nvidia.conf, if you want to return the default value. Note:
 It is possible to use more memory (?)

 NVreg_DynamicPowerManagement=0x02 - Enables the use of dynamic power
 management for Turing generation mobile cards, allowing the dGPU to be
 powered down during idle time.

 NVreg_EnableGpuFirmware=0 (Default 1) - Disables GSP Firmware on NVIDIA's
 closed source kernel modules. This option is ignored when using NVIDIA's
 open kernel modules.

 nvidia_drm.modeset=1 (default 0) - Enables modesetting support for the NVIDIA
 driver. Critical for Wayland support and proper PRIME Offload operation.

 nvidia_drm.fbdev=1 - Enables hardware framebuffer support. Allows to use
 native display resolution in tty. This option has no effect on PRIME laptops,
 as the framebuffer is handled by the iGPU. This parameter is marked as
 experimental, so bugs may occur.

General common parametrs used for nvidia on modern hardware. Also do u have installed prime-run or switcheroo-control in system?

weird then,try add this parametrs

options nvidia NVreg_UsePageAttributeTable=1 \
    NVreg_InitializeSystemMemoryAllocations=0 \
    NVreg_DynamicPowerManagement=0x02 \
    NVreg_EnableGpuFirmware=0
options nvidia_drm modeset=1 fbdev=1

in /usr/lib/modprobe.d/nvidia.conf save and reboot

Do u use nvidia as main card, not as 3d accerelstion only for games? I personally use for all cases Intel graphics for everything and nvidia as accelerator with switcheroo-control to call nvidia rendering.DM to me don’t wanna spam in comments.
