You know better, I never have had an Android, but some time ago I’ve tried searching if you can get screen time data older than 2 months and came to conclusion you can’t do it on Android either. But probably it’s not an issue if you can automate export and perform it regularly.

It would’ve been cool to have accumulative screen time across all devices. But as iOS user I don’t dream of it.

It will not.

$ time get_screen_time
03:33
real    0m0.005s
user    0m0.003s
sys     0m0.007s

I don’t know about android, but on iPhone only way to export screen time data is to screenshot it. Probably android is also restrictive.

Can you give a hint on how to control screen saturation with color profile? I suppose task is to create synthetic color profile, without any calibration devices. I’ve spent some time trying to create such profile, but failed, all I found is gnome-gamma-tool, but it can create only VCGT tag.

This is so cool. I will check my Plasma version. What about Mac, are they also capable of fullscreen color management?

KDE Plasma, select the “built-in” color profile, and you’re done, no more oversaturated colors

Just did it. Fullscreen, not oversaturated. How is it even possible. ICC profile is built-in in memory of my laptop screen? Even Windows can’t do it. There’s a billion of tabs and menus in color management settings in Windows. I’ve spent billion time on this topic and you tell me I can just click a checkbox, even without a terminal? Why Gnome even exists…

There is no saturation slider, though. I’ve seen it on some screenshots.

I wonder, if ICC color correction is applied to full screen without apps even knowing it, what about color managed apps? They still apply their own transformation beneath, which makes output being affected by two color profiles, or by a single one but twice?

This is very promising. Thank you for the tip. I thought my only hope is CTM. Day of switching to KDE is now closer to me.

That’s interesting. I’m on Gnome. I thought presence of this color tab depends on whether Linux kernel, VGA and VGA driver support Color Transformation Matrix or not. It would’ve been nice to solve half of my problems just by switching to KDE.

I’ve spent a lot of time on color profiles and I didn’t include section about them because I came to conclusion it’s not possible to affect fullscreen saturation with them. Are you sure you can affect saturation system-wide with color profiles? Because in Gnome it’s not possible. I actually asked it in my post originally but no one commented on this matter yet.

I was able to access this forum but I doubt it is related to my question. nvidia-settings was last mentioned in September 2024. 17 mentions of xrandr overall.

In X11 there is no Color tab for me either.

wlr-randr doesn’t work: compositor doesn't support wlr-output-management-unstable-v1. Probably wrandr (it’s not even in apt repo) will not work either, also gamma is about contrast, not saturation.

Can’t access this url, it never stops loading. Maybe I will try Tor later.

My laptop screen doesn’t have physical buttons and ddcutil and ddccontrol don’t work either.

I was using fork of this extension. Original one you’ve mentioned works in Kate too, thanks! I hope I will not return to this question anymore. I think this one has a bad name, it’s easy to overlook it in search through gnome extensions website.

For Bash - try blesh, it will enable some of common controls by default, and probably you will be able to manually enable other shortcuts. PSReadLine is calling xclip each time for copy/paste action for clipboard sync, probably it will be possible with Blesh too.

I’m fine, I got what I wanted. Apparently, it isn’t un-feature of Linux, it’s un-feature of ReadLine which is shipped with Bash.

I’ve got what I wanted, but I’m a powershell user. For Bash, blesh looks very promising - it’s functionally same component as PSReadLine which makes all this stuff possible in pwsh.

one of many un-features in Linux

What exactly? Shift-selection is already possible with Blesh. I think I’ve seen scripts for synchronizing buffer with clipboard. And everything else is a matter of redefining existing shortcuts.

I’ve heard about Linux being highly customizable and decentralized OS, and suddenly I can’t define my own shortcuts because there is a list of un-features?

I don’t care about Vi and Emacs, I already have my workflow and I’m trying to transfer it to Linux. When I will succeed, then (maybe) I will spend some time to explore other ways of interacting with terminal. Otherwise, it’s not freedom, it’s becoming a victim of OS.
