my problem with linux is almost 9 years old.
Right now I use Linux Mint 19.3 - Cinnamon. My laptop is connected to a Samsung 40’’ TV-screen. The laptop screen is disabled and I only use the TV screen.
In short the problem is that if select the resolution of 1280x720(16:9) I can see the image crisp and clear, BUT the mouse is moving a little sluggish. If I change the resolution to 1360x768(16:9), the mouse is working crisp but the image is slightly fuzzy. The outline of the letters is not clear. If I read for an hour like that, my eyes are full of tears. But all the animations work a little faster. It feels like I gained another 1GHz on my CPU. It's not that big of a difference but it's there My biggest frustration is that with Windows(7/10) installed on my setup, everything is working fine, except...the OS
I always had this problem on all the distros that I tried along the way, including Manjaro. The problem with the sluggish mouse is only on TV. If I take a print screen with each resolution I cannot see the difference in the photos. No matter the resolution, on laptop's display the mouse is moving perfectly. I have tried with a different 4K HDMI cable...it's the same. I have tried with NVidia drivers, it's the same but worse, because then I get huge screen tearing and none of VSync Methods work. I tried many things found on forums but I'm still a newbie and I ended up eventually breaking the sistem without knowing how to repair what I have changed. But as always, my guardian angel - Timeshift - was there to rescue. I even bought a Logitech G603 hopping that a bigger DPI will solve the problem
I had some small luck with changing the file 50-mouse-acceleration.conf in /usr/share/X11/xorg.conf.d/
"InputClass" Identifier "My Mouse" Driver "libinput" MatchIsPointer "yes" Option "AccelProfile" "flat" EndSection
With this the mouse it working a tiny bit better
I really don't know if there is maybe a holly combination between a setting from OS and one from the TV for it to work.
Maybe some of you who are good also with TV settings have a tip for me ?!
I would appreciate it so much !!!!!!
