Good evening, I’m not sure that the category is right this is my first post and I’m a linux beginner.
I’ve installed Optirun-switch on my laptop and everything goes fine with Intel configuration but when I tried Nvidia configuration I get black screen with underscore on the top. How can I boot again into the system and eventually solve the problem?
The Nvidia card is gtx 1050, I don’t know if it can help.
Thanks you in advance.
Have you seen and read through this wiki yet?
Yes I’ve followed it step by step, but I skipped the last part for the tray app, I don’t think it could be a problem
https://discovery.endeavouros.com/system-rescue/how-to-boot-without-a-graphical-environment/2021/03/
and revert settings from TTY could be what helps you.
And welcome 
Thanks you so much, exactly what I need, I’ve fixed the black screen problem that was the most annoying. But I didn’t understand why this appens with set-nvidia.sh. I tried to configure Optimus-manager without success. Any idea to fix Optimus switch?
Sorry I didn’t understand what do you mean.
the dev is a user here at the forum and should give a hint what could be wrong 
Not enough information given by the OP to even make an attempt to troubleshoot. How about we try this, please read this link and provide the basic hardware information.
Take special note of how to post this information here.

I’ve also noticed on booting with intel configuration appears :
[FAILED] Failed to start Load Kernel Modules.
But after this it will continue without any evident issue.
It looks like no driver for the nVidia card is installed. Make sure that the driver is actually installed.
pacman -Q | grep nvidia
If it is not installed, make sure to install it.
Also, HP laptops can be “fun” when it comes to Linux, especially Optimus Graphics with Arch. Sometimes, the ACPI tables can cause issues. Try adding acpi_osi='Windows 2017' and reboot.
If you need instructions on how to do this, take a look at this article:
Here it is the output, it seems to be ok isn’t it?

I noticed it, I’m having so much “fun”…
Yes, that looks good.
Give the kernel parameter thing a try. That is what I had to do to get the Optimus setup (Optimus-Switch) on my laptop working properly on Arch.

I would also go take a look at /etc/gdm/custom.conf and make sure the # is removed before the line #WaylandEnable=false. This will make sure that Gnome does not try to load Wayland first before falling back to X11. Both Optimus-Switch and Optimus-Manager do not play well with Wayland.
Also, your OP was unclear, what did you do to try and get things working? Can you post things in the order you did them? Optimus-Switch and Optimus-Manager do not play well together.
If Optimus-Manager was installed, there are more steps required to remove it than just uninstalling the package. You need to run optimus-manager --cleanup BEFORE uninstalling the package to have it completely uninstalled. Also, since you are running Gnome, Optimus-Manager requires that you use GDM Prime instead of the default GDM (This is the screen that you log in on). You would also need to switch back to the default GDM. To be honest, that is beyond my knowledge.
I started the nvidia cofiguration following the Welcome guide to get Optimus-manager. I carefully followed every step from that guide, I tried to install GDM Prime, but something went wrong because from yay it gives me an error. I tried to solve it but without success, so I decided to get Optimus-switch, but I skipped the command optimus-manager --cleanup and I just uninstall it. After that I followed every step from the welcome guide to install correcly op.-sw.
Okay, when you installed your system, were you able to boot into a desktop after the initial install before doing any configuration?
I don’t remember it was a mouth ago. Only a few days ago I decided to set up nvidia, but probably yes.
Did you make a backup before doing anything? If so, I would revert back before doing anything else and see what happens.
Hopefully someone can pick up form here, it is very late where I am at and the morning is going to come too soon. I have to get some sleep. Also, we are approaching the limits of my knowledge.
No backup I’m sorry. Please go to sleep, the most important thing was to have access again to my system just to use some programs that I need for University (I’ve checked that they work). Maybe next week if there is no solution I can do a fresh install and give Op-sw another chance. Thank you so much.
