+# Lenovo ThinkPad X12 Detachable Gen 1
+
+This is the laptop I use for work for a few months now.
+The laptop is leased, and was built on late 2021.
+
+## Linux compatibility
+
+Linux has several problems:
+
+* The keyboard is really a USB device (it is detachable), and you can only switch ctrl+fn using a Windows app.
+  [I investigated how to do this from Linux without much success.](https://github.com/alexpdp7/lenovo-thinkpad-x12-detachable-gen1-swap-ctrl-fn-linux)
+  This is really painful for me, and the main reason for using Windows.
+
+* Apparently, you cannot use the volume control keys in Linux either.
+  However, I do not use those in Windows so I don't care.
+
+* If you search the Internet, I think you will find more issues, but I have not used the laptop with Linux enough to experience them.
+
+## Form factor
+
+One of the main reasons for picking this laptop is that it's very light.
+The laptop with keyboard weighs 1.1kg.
+
+The keyboard is detachable, which has pros and cons:
+
+* You cannot comfortably use the laptop on your lap.
+* However, detaching the keyboard and using it as a portrait tablet to read documentation is great.
+
+### Keyboard
+
+The keyboard is very good, but slightly inferior to a full ThinkPad keyboard:
+
+* There is no insert key.
+* For me, muscle memory does not work well when switching to a full ThinkPad keyboard.
+
+However, it still is a pleasant keyboard to use.
+
+### Screen
+
+The screen looks good.
+But because it is glossy, sometimes I have issues with reflections.
+
+### Battery
+
+I have only used the battery when it was three years old already.
+I can use the laptop for about 4 hours of somewhat intensive usage (some calls, working with compiled languages and LSP).
+
+### Pen
+
+Unfortunately, the leaser did not deliver a pen.
+
+## Others
+
+Besides what's been mentioned, I do not find any other problem with the laptop.
