https://www.dreammachines.pl/en/lapto... I have this hardware.

I tried installing RPMFusion and Negativo17 drivers - without success. Both of them seemed to have the same issue - after rebooting, I couldn't get to the login screen(SDDM). The screen was just flickering. I could get to the tty's, but writing anything was a pain. I had to push the keys multiple times to get a word right.

Things I have tried so far: https://wiki.archlinux.org/index.php/... Optimus#SDDM This config https://wiki.archlinux.org/index.php/...configuration

https://wiki.archlinux.org/index.php/...failswith.22noscreensfound.22withInteliGPU <-- I launched 'startx' somehow in the tty and it showed 'No screens found'. I used this solution - no success.

Please tell me if you need more information, I have a feeling I haven't provided enough, I can't think of anything right now.

Links with underscores are braking here, use Ctrl+L in editor to paste links.

Update BIOS and check it for settings pertaining GPUs, there should be (depending on what manufacturer provided) three options available:

integrated - it'll use only Intel GPU, you won't have to install any drivers;
discrete - it'll use only Nvidia GPU, RPMFusion drivers without any additional Optimus related changes should work well;
switchable - it'll use Nvidia GPU on-demand, for now you'll need Bumblebee for it to work reliably. Read this wiki to find out about installation, usage and troubleshooting. Bumblebee works better then Optimus. For older GPUs, where nouveau (open source driver for Nvidia GPUs) support is better, PRIME provides good out of the box experience.

If you don't find these options, then 3rd one is implied.

You'll probably have to undo previous changes and clean-up after those drivers. If you decide on reinstalling Fedora, use one of those updates ISOs.

There are some issues with KDE + Nvidia proprietary driver that Nvidia seems to ignore, so get ready for some additional tinkering.

Bumblebee isn't going to help with anything - the driver just does not work. I tried to get it working many times(Bumblebee). Anyway, I am trying to get it working with NVIDIA GPU only, and I haven't succedeed with that, so Bumblebee will definitely not help either, since it requires.. a working NVIDIA driver.

You should have included this information in the question...

The problem was the 20-intel.conf file I forgot to delete - having other Device config files for Xorg seemed to clash with Nvidia drivers. Then I had to add two lines to /usr/share/sddm/scripts/Xsetup

xrandr --setprovideroutputsource modesetting NVIDIA-0 xrandr --auto
