Infinix

Since I’m moving to Linux, my Copilot key becomes useless. Let me rephrase that! Even when I was using Windows, I never using this Copilot shortcut key in my keyboard 😬. Fortunately, using Linux I can remap this key for something else more useful. Requirements A laptop (I’m using Infinix Air Pro+) with a working keyboard. keyd Finding what this Copilot key do Open your favorite terminal and execute sudo keyd monitor. This command will print what events are triggered when a particular key is pressed. Press the Copilot key and read the output. In my laptop, it print out this: AT Translated Set 2 keyboard 0001:0001:70533846 leftmeta down AT Translated Set 2 keyboard 0001:0001:70533846 leftshift down AT Translated Set 2 keyboard 0001:0001:70533846 f23 down Now I know that my copilot key triggers leftmeta, leftshift, and f23. It’s seem legit combination of modifier keys and a function key. But unfortunately when I tried to use it in my desktop environment (I use KDE) to bind a shortcut, it only detect the modifier meta and shift. keyd for the rescue Edit /etc/keyd/default.conf file and I added these lines: ...

I installed Linux (EndeavourOS) in my Infinix Air Pro+ last week and noticed that the sound coming from the speakers was bad. This laptops has 4 speakers, hence only 2 of them are working. This is how I fix this issue.

I have Infinix Air Pro+ and I use it for my work. I can say it is a good laptop coding mainly because it has 2.5k OLED 16:10 screen. But I found a problem with its screen color. When the screen brightness is below about 50% and the screen turned off (to save power, not necessarily going system sleep/suspend) and turns back on, the color looks washed out. First time I noticed this issue is because I was using a pitch black wallpaper image (so I can flex my OLED display). After my screen turns back on, my wallpaper’s black color becomes grainy, washed out, as its doesn’t have pitch black color anymore. Then I noticed, the color will be fixed after I crank the brightness to above 50%. Turning the brightness down again after this still gives me correct black level. ...
