Nvidia 435 drivers and Optimus

tboerc We will support it, But I'm not patching Xorg to make it work. We will be waiting for the next Xorg release.

Just try the optimus switcher.
Left below.
Works fine and reliable on my laptop.
So I am served and completely satisfied.
And, basically, it's easy to install.
IMHO is idiot proof.

tboerc Hybrid mode is when you want to use GPU's computation power but not to use it for rendering. For example, if you have a GPU enabled tensorflow installation, you can use hybrid mode to enjoy the strength of GPU for deep learning but without using it for Xorg.

tboerc Anticipated. I am actually inclined to write down details in my mother tongue, German, here because I could describe it as best or more excellently. My english from the wrist is a bit rusty and not very good. But what should it be. I beat then the text here by an online translator and hope that it fits and still understandable comes over.
On the hardware side, AFAIK are most laptops called clevos, which are then branded and slightly modified depending on the manufacturer. Most chipset, cpu and gpu are therefore identical. Some manufacturers like asus and acer, for example, mostly build themselves and are not clevos.
You hear and often reads that you should simply turn off the intel gpu in bios, and then only the nvidia is running. That can go well. But mostly it does not. Because the intel gpu loops through the nvidia. It can happen then that when you turn off in bios, then the screen remains black. Therefore, the option of switching off is often not available. Some very clever force then the extended bios mode to get to this switch-off option. But then stand or sit in front of a dark screen. Remedy is then always the hardware-reset, or the panic call in support.

Bbswitch, bumblebee, optimus and primus are AFAIR old stuff that is little or no longer developed, or always costs performance. On top of that, I find this method (not just me) stale and ineffective. One does not reach the full potential of nvidia gpu.
This results because the nvidia is switched on according to load. When the intel gpu reach their limits, the nvidia turns on and takes over. And that is IMHO unreliable.
I do not know how it works with windows, because I have consistently been using linux for about 15 years. So on my computer is not running windows.

The proposed method 'optimus-switch' works for me as I said excellent.
Here, the linux is forced to quasi just and alone to use the nvidia gpu.
Accordingly is the performance. Unlike bbswitch, the full 100% performance of nvidia is available. The slower negotiation of performance is completely eliminated.
In everyday use, I only use the Intel® HD Graphics 630 (Kaby Lake GT2). That's enough for most things. Such as to watch in Amazon movies in HD, or youtube.
My laptop is a gaming laptop.
If I want to play, I switch over the terminal, log out and back in, and then only the nvidia runs.
This can be recognized by 4 things.
Under the DE budgie and gnome, you can see in the settings under info, which gpu grade is active. Or just about the query in the terminal.
The nvidia settings can then be opened and work as it should or as it should. And, you can tell by the fans.
In intel mode eg. Only the cpu fan turns up. The gpu fan of the nvidia barely audibly runs idle.
I switch to nvidia mode, run or turn both fans fully on. My laptop has 2 fans. An extra for the nvidia, and just one for the cpu.
In bumblebee, optimus or primus mode the performance is a lot worse. And that measurably or noticeably.
For example, I had to start steam with 'primusrun steam', or 'optirun steam' so that the games all run with the nvidia power. The performance I found grudging compared to the switch method. However, there was another known linux on my laptop. But the principle or the method is the same.
The switch method gives me full control and the best performance ever. So 100% nvidia power, without the disturbing negotiate.
A good friend has practically the same computer (laptop) as me. Hardware is identical. However he uses windows.
At the games rise of tomb raider and dying light eg. , I have a lot of FPS more than him. ;-)
And partly noticeable.
With the bbswitch or bumblebee method that was a lot different or worse. In fact, he was traveling faster with his windows system.
Bbswitch or bumblebee decides, if you use it, what you get in performance.
However, with the optimus-switch method, I have full control and decide for myself.

Quinix I have a lot of FPS more than him
I really loved to read that. You know if they give support to linux as they give to windows, gaming on linux could be better by far.

I have to add something important here.
And indeed it is so that solus linux in things hybrid gpu a different philosophy or method preferred or used. Using hardware driver installation (doflicky?) you can either install the nvidia driver, or the intel driver, reboot and then use each.
That too works (for me for a while) also quite reliable. And the performance is exactly the same as with the optimus-switch method. It is either one or thing.
However, this method IMHO is the brutal method. Because when you uninstall and install, depending on the driver, it happens that the computer hangs itself and you have to perform a hard reset, or turn off the laptop and turn on again. Just brutal, it scares and prays that everything still works.
Personally, that annoyed me permanently. And so I was really pleased to have discovered the optimus-switch method, which is much softer and more elegant.
You go to the terminal, switch over how you need it, log out and log in again and you're done. Without hard reset or reboot.
For example, you could create a starter for the respective mode on the desktop, or make an applet for the taskbar, to toggle the status and the switch including the logout and logout. I appreciate an accomplished coder makes or realizes this in a jiffy.
Aubik is already commonplace among the ubuntus.
Here the Solus people would be in demand.
Whether you record the optimus-switch thing in the repos, build a simple installation script and build a switch applet for the taskbar.
That would enhance solus linux by many and make it better.
And I am firmly convinced that for a good coder is a klacks or children game.
Unfortunately, I can not do it myself. The terminal is enough for me. Where I get that with the starter on the desktop (which then only calls the terminal) more likely to get on the chain.

How does it look like dear solus maintainer? ;-)
Do you get that, or maybe you at least take a look at it?

Quinix Doflicky is just for installing the drivers. linux-driver-management is our partially working optimus solution. You can use it to set which device to use from the command line, but IIRC it requires either restarting lightdm/sddm/gdm or rebooting. It was never intended on being our final implementation though. Ikey was thinking of ways of doing it automatically long before PRIME Offload was even being dreamed up.
