xrandr: Failed to get size of gamma for output default

I have learned how to add my resolution so it’s recognized in xrandr but I am still unable to actually change to this resolution.

I have installed all the dependencies required from my reading, most of them already were installed, except maybe the backports? I may have broken some packages.

Do you think the next version of Parrot OS will have the updated debian bookworm kernel so that everything may work out of the box then?

I am trying to learn how to program as well as information security best practices, ParrotOS seems to be the exact OS I am looking for as it has everything pre-installed for a developer environment, python, node and go. This resolution is going to drive me up the wall though.

I have so much to learn that I don’t really want to keep playing around with this atm, really curious if the community thinks this could be resolved with the next ParrotOS update.

I appreciate any feedback, thanks guys.

that usually means its using a fallback driver, try updating those first;

sudo apt install xserver-xorg-video-amdgpu

[devrewoh (Chris Hower)]

I believe I already have that installed. I think the problem is because I’m on some of the latest hardware and correct dependencies/firmware/backports aren’t installed and/or manually configured but I’m having difficulties finding the correct resources. Here are some additional screenshots if anybody can take a glance?

Any help would be greatly appreciated, I’m excited to make ParrotOS my day to day OS.

Device AMD Driver N/A means it needs drivers, try this to get your AMD card fully enabled;

sudo apt install firmware-linux firmware-linux-nonfree libdrm-amdgpu1 xserver-xorg-video-amdgpu mesa-vulkan-drivers libvulkan1 vulkan-tools vulkan-utils vulkan-validationlayers mesa-opencl-icd

Hey sorry for the lately reply, but do you have any specific error of missing binary files in sudo dmesg?
Seems like somebody is having a similar issue here

How to get 7900 XTX working?

I think you should give this a try
https://amdgpu-install.readthedocs.io/en/latest/

I don’t know much about AMDGPU so I’m afraid I can’t help you much. I’m using Nvida on my all devices.
