Unity3d Ubuntu: Changing to Vulkan Graphics API for Linux Freezes - unity3d

I am running Ubuntu 22.04.1 LTS. In order to solve the problem posed in my older question (Unity3d: "Platform StandaloneLinux64 with graphics API OpenGLCore is with HDRP"), I switched the Graphics API from OpenGLCore to Vulkan:
When change the order to have Vulkan first, the editor only freezes and cannot proceed.
Any ideas?

Which Ubuntu Versions can run Unity

I have recently switched from Windows to linux, Windows 10 pro to Ubuntu version 22.04 LTS to be exact. I now wanted to install Unity on my computer.
The problem is that when I open the Unity Hub, all I see is a grey screen with the sub Menus having no options when hovering over them.
What I found is that it apparently is this way because Unity only works on ubuntu 16.04 and 18.04.
However, I have found people that claim it works on versions 20.04 and 22.04. Having received contradictory information, I dont know what the truth is, so now I'm here.

Can't access unity package manager on ubuntu

I recently installed unity on my laptop, but I realized that I can't access some of the features like package manager and asset store directly from unity which is a bit annoying. I'll leave you a screen shot of it.
Edit: I forgot to mention that I am on kubuntu
Thank you for your help.
I don't use unity on Ubuntu but I think they took the same ui from the windows layout but they didn't implement the asset store feature on the Linux based version

Hololens Emulator: Unreal Engine app completely black, though Win64 works

I have taken the "default game" (tables and chairs) of Unreal Engine 4.26, and packaged it for the Hololens emulator using these instructions.
I can launch the latest Hololens emulator (10.0.19041.1136) and install the Unreal application, and an icon shows up for it in the apps panel. But when I launch the app, the entire screen is black. When packaging the application for Windows (64 bit), the application works just fine.
What could be the issue? Older versions of Unreal Engine work fine, in particular I have verified that Unreal Engine version 4.25 works with the emulator.
Other perhaps relevant info: Intel Core i7-5960X, Windows 10 version 1909 build 18363.1440, NVIDIA GeForce RTX 2080 Ti, Version 456.71.
I have also used the Unreal 4.26-chaos engine, completely fresh. I choose a blank project from the Games category, C++, Scalable 2D or 3D, raytracing disabled, mobile/tablet with starter content. Then add the Microsoft Windows Mixed reality plugin and the Hololens plugin. In settings I get a signing certificate and define a project name, using Windows SDK version 10.0.18362. Again, no joy. The same thing, just as a Blueprint, not a C++ project, also does not work.
Also checked Hololens emulator version 10.0.19041.1117. No joy.
We followed all the steps exactly per docs including the “run in VR mode setting” in packaging and reproduced this issue today.
So, we are going to recommend to you to file a defect over with UE 4.26 via Unreal Engine Support | Get Help and Customer Service for UE - Unreal Engine. Besides, you can also open a support case via http://aka.ms/hololenssupport for free to discuss further too on anything we can offer for HoloLens 2 emulator/device:
The issue in the Epic's article. You should enable the "start in VR" option in Project > Description > Settings as from
https://learn.microsoft.com/en-gb/windows/mixed-reality/develop/unreal/tutorials/unreal-uxt-ch6
It was added in 4.26.
And we don't support Unreal 4.26-chaos yet. Please take simple 4.26.

Porting to Qt5.6 or advanced causes application to use ANGLE instead of OpnelGL 3.x and causes black screen instead of rendering actual image

I have recently ported our application from Qt5.5 to Qt5.12.1. On i5 processor Windows 10 the application runs fine. However on i3 Windows 10 Pc's we get a nothing but a black screen. The application runs fine on i3 Windows 8 though.
On further digging, we found out that the issue occurs only on devices where OpenGL version is 3.x and it works when the OpenGL version is 4.0+. That's why it worked in i3 windows8 which has 4.0 version of OpenGL.
For Qt5.5 it works, but if we port to even Qt5.6 it does not work. We cannot find anything on release notes or known bugs from Qt. We are using OpenGLfunctions and QOpenGlWindow.
Information from the logs of Qt5.5 build:
glVersion 3.1.0 - Build 9.17.10.4459
Information from the logs of Qt5.6 and 5.12.1 builds in the same machine and same environment:
glVersion - OpenGL ES 2.0 (ANGLE 2.1.0.57ea533f79a7)
I would like to know whether I am missing something that I should do while porting Qt versions? or is it a bug in Qt?
How can I force Qt to use available OpenGL version instead of using ANGLE?
I would also like to know if we can downgrade OpenGL version of the windows 10 to re-create it easily on other devices as well for testing purposes.
Thank You.

Genymostion Start with white screen

I have a laptop with i5 configuration and I have a PC with Intel Q33 motherboard and core2Deo. In my i5 its work fine but in Q33 first give me OpenGL error but I upgraded the graphic driver and the problem solved. But in my PC when I start a genymotion device it start with white screen and dost allow any thing to touch...
I have done following solution
upgrade my Graphic Driver
Reinstall VBox of oracle
Reinstall Genymostion and download devices
so it no issue with installation of the genymostion but still i gatting white screen ...
Upgrade your OpenGL Version to 2.0 or higher.
Please Check Requirement of Genymotion and check your system configuration.
In VMbox the android virtual machine is working. and on geymotion having the same above issue.
I have update my video card too .. using win 7
Now I get to know that my chipshet have no updation for OpenGl.
So, It's not going to work for me.
