I am new to the world of Linux. I started with dual-booting Ubuntu on my desktop in the spring of this year. Recently, I installed Kubuntu on my old HP laptop to bring it back to life, and it's done wonders in terms of speed and stability. I really love it. The laptop has an Intel GPU/CPU combo chip as well as an Nvidia GPU chip. After some research, I learned that Linux operating systems tend to have some difficulty knowing when to swap between the two, and prefer you just use one GPU. I have installed the latest official Nvidia drivers (515.76) and have enabled "High Performance" mode in the "PRIME Profiles" section of the Nvidia X Server application.
After rebooting, the KDE GUI inflates the system font to a much higher DPI than it should. Applications launched within the OS look normal. I have searched the internet for solutions and found that forcing the font size in system settings to a specific DPI (like the default of 96) fixes pretty much everything... except for the login screen.
As you're likely aware, due to the nature of the KDE startup process, my forced font size setting only takes effect after login. This means that while the rest of the operating system looks great, including the lock screen, the login screen is still stretched.
I have scoured the system settings and Nvidia settings for some kind of option I'm missing. I've tried solutions I've come across online. I have tried using xrandr to manually set the resolution and DPI. I tried purging all Nvidia content and completely reinstalling them. I've tried modifying Grub at startup (when you press 'e' on the Ubuntu listing just after the bios) to try and use nouveau at login instead. None of these options have worked.
This issue is certainly not the end of the world, but it would be nice to have the system look clean and uniform. For the time being, I have swapped back to the "On Demand" Nvidia Server X setting so that the Intel GPU is utilized and everything looks normal. When I want to play games on Steam/Proton I just re-enable High-Performance mode. If you have any ideas I should try, please let me know. Thanks for reading!
