unity has returned. this is ubuntu’s original desktop environment. it’s pretty fast. but the only thing missing here is “Night Light”. to Ubuntu Unity Devs. I hope you will meet my request. I’m not the only one who will benefit. as well as other ubuntu unity users. because blue light hurts the eyes. especially when staring at a computer or laptop for a long time. that’s why if you add this feature by default. maybe more users will be encouraged to use it. Night Light Feature.
You can easily install Redshift and try that.
