XUbuntu 20.04 USB dongle (wireless) mouse lagging

ng flag

I tried multiple "solutions" but nothing worked. I can't try to use USB 2.0 because the laptop only has 2 usb3.0. tried:

20.04 USB keyboard and mouse lag

laggy mouse pointer in ubuntu 20.04

How can I get rid of mouse lag under Ubuntu?

Ubuntu 20.04.1 LTS GNOME 3.36.3 periodic mouse and keyboard lag

Also, it's not the screen refresh hz since the laptops touchpad is working fine.

Do you have anything else on the USB bus, such as a large amount of storage, an external video card, or a monitor?

nothing, only the usb dongle for the mouse, not even a keyboard

Are you using PowerTop or another power management system? If so, this could be putting the dongle into a low-power mode, which would reduce overall throughput
ng flag
no, I'm not using any kind of power management system. It's nearly brand new installed os. Only some apps for programming and the necessary packs for those few languages

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
