Hello, I am a new linux user, I have debian installed on my laptop. I intended to use the OS as primary to learn about linux. However, the system kept feeling choppy, and lags a lot. For example, youtube videos stutter a lot even after they have loaded, and I had to reboot to windows to type this because it constantly kept hanging and then a certain character got typed 20 times. Even when playing csgo I am getting very low framerates. I have installed the latest nvidia non-free drivers and have bumblebee installed. I tried the optirun launch option, but still the game seems to be using my iGPU instead of nvidia.
Any help with this issue is most welcome, I don't want to give up on learning linux and go back to Windows.
My system specs are:
i5 8300H
8GB DDR4
Nvidia GTX 1050 Ti
Samsung 970 Evo 500 gb

would be nice to specify exactly your OS, what did you install and how. What's happened, what was the response....
It looks like your video driver was not installed properly.

Your system is strong enough and should not do that.
How did you install debian? Which desktop environment is it using?
Has the problem you describe always been the case?
Have you done anything to the system since installing it?

What does your task manager / system monitor say about what processes are taking up most resources (CPU, RAM, disk I/O)?

@pan64 and @ondoho , by my knowledge I checked the system monitor, the CPU usage is 8-10% and there is 7.8 gb of RAM and 7.6GB of swap available, so it looks normal.
I am running Debian 10 Buster, with GNOME 3.30.2. The graphics show up as Intel UHD Graphics 630. I don'tttttttttttttttttttttttt know how to check what drivers are installed or anything, but I have followed the install instructions forrrrrrrrrrrrrrrrrrrrrrrrrr bumblebee on the debian wiki. If there's to check, askkkkkkkkkkkkkkkkkkkkkkkkk me and also mention how to check it, thanks.

PS- the "don'tttttttttttttttttttttttttttttt" and other words are intentionaly kept as examples, similar stuff is happening with typing this (about once every 3 words) - accidentally spacing or backspacing too much, a key gets held down, video playback on any player and on browser is extremely choppy, it should work fine even with on board graphics if that were the only problem, right?

Debian is not documentation poor.

If you have only intel graphics there's no point in installing bumblebee. At all.

I suggest you reinstall and see if your system works as expected without any additional "install instructions".

@ondoho no my system does have an Nvidia 1050Ti gpu, it just dosen't use it for some reason. It is a laptop. Also, I tried reinstalling it 3 times, to no avail every time it's the same thing

Suggest reformatting partitions and installing the debian-based antiX 19.1, Base.
Then familiarize self with the smxi script, especially continuing along through the menus until the menu with the option to 'continue to graphics' is found, going to it and, preferably, installing the nouveau drivers.

Hope this helps; but I suggest since you seem persistent and do not mind reinstalling.

Your GPU is not 'optional' with the default being Intel, it it? Wouldn't know how to proceed if this is the case.

Best wishes!

Yeah it is, can't just change my display cable to the nvidia card and be done with it XD. I tried some other options, but none worked.

I will use debian on VBox until I learn it better, glad for your replies guys, i'll close this thread now.
