as the title says, I'm having trouble getting Ubuntu running with acceptable performance (really any Linux distribution I tried, but Ubunutu is especially slow). The main problem I is everything I do becomes really slow when using Microsoft Teams or IntelliJ Idea. Both are causing high CPU usage not only after startup (i.e. also after indexing etc. of IntelliJ), but every time I do anything in one of the programs. At first I thought it's a problem with Microsoft Teams, but I had the same issue also with Zoom and Teams web clients.
I'm using the Lenovo Thinkpad P14s:
- 15.3 GiB Memory
- Intel Core i7-10510U CPU @ 1.80GHz x 8
- NVIDIA Corporation GP108GLM [Quadro P520] / Quadro P520/PCIe/SSE2 Grahics and the std. Intel Graphics onboard chip.
- As OS I'm using Ubuntu 20.04.1 LTS 64-bit.

I also tried different OS (Linux Mint with both Cinnamon and MATE, Pop!_os since people on the internet claim it has good Nvidia Graphics support or something, and I also tried KDE Plasma desktop for Ubuntu as well as standart desktop. On some of these OS the general performance was good except when using Microsoft Teams (it really kills the performance). But the performance with Teams (or Zoom web) is really bad on all of them. I also have Windows 10 partition, everything is running fine there.
I tried a lot of stuff so far, which is why I think the above information matter. Anyone any idea? Is it possible, that (despite inxi reporting the Nvidia graphics are used) only the processor is used for graphics? If so, how can I change it. Also is there any option to force Teams/Idea to use Intel graphics (while keeping the Nvidia card as 'main')?
If you need any additional information, I will provide.
Thanks in advance!

. It only pulls in a few dependencies and is a great GUI way to view your logs. You'd be looking for errors, most specifically for errors that keep repeating.
