How to adjust fractional scaling in Settings/Displays in Ubuntu 20.04 LTS using keyboard shortcut or command line?

pe flag

I am using 125% fractional scaling in Settings/Displays in Ubuntu 20.04 LTS. It works great!

However, VMware player 16.2.1 (with enabling 'Accelerate 3D graphics') Windows 10 client can't display full screen mode on two physical monitors correctly in Ubuntu host with 125% fractional scaling. VMware Windows client works great when Ubuntu host is 100% fractional scaling.

I tried to find a solution for the problem above but no luck. I think a workaround is to change fractional scaling as 100% in the Ubuntu Setting before launching WMware and change back 125% after closing VMware. In order to adjust fractional scaling efficiently, I wonder if there is any way to adjust fractional scaling in Settings/Displays in Ubuntu 20.04 LTS using keyboard shortcut or command line?

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.
