preface: Posting these online since it sounds like these notes are somewhat interesting based on a few folks I've shared with. These are semi-rough notes that I basically wrote for myself in case I ever needed to revisit this fix, so keep that in mind.

I recently bought an LG ULTRAGEAR monitor secondhand off of a coworker. I really love it and it's been great so far, but I ran into some minor issues with it in Linux. It works great on both Mac and Windows, but on Linux it displays just a black panel until I use the second monitor to go in and reduce the refresh rate down to 60 Hz.

This has worked decent so far but there's some issues:

• It doesn't work while linux is booting up. The motherboards boot sequence is visible just fine, but as soon as control is handed over to Linux and I'd normally see a splash screen while I'm waiting for my login window, I see nothing.
• It doesn't work on the login screen. This would be fine if login consistently worked on my second screen, but I need to manually switch

Some projects may have files that should be skipped in Git diff but still show in Git status (and be tracked). This can be made possible with a custom diff driver that uses a no-op command.

Adapted from StackOverflow - @KurzedMetal.

Custom diff driver

Create a global no-op diff command driver with the following command. Note that driver can be limited to local respository by removing the --global flag.

git config diff.nodiff.command /bin/true

Need

Convert .mov/.MP4 to .gif

Reason

As a developer, I feel better to upload a short video when I create the pull request to show other viewers what I did in this PR. I tried .mov format directly got after finishing recording screen using Quicktime, however, gif offers preview in most web pages, and has smaller file size.

This is not limited to developer, anyone has this need can use this method to convert the files.

Navigating while typing

Let’s start by what you can do while typing. These keystrokes change only what happens on the input line (the line where you type stuff).

arrow left/right: move one character left or right.
