Hacking the LG Monitor's EDID

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

Fix Task Manager blurriness on different DPI monitors in Windows 10

Fix Task Manager blurriness on different DPI monitors in Windows 10

Task Manager on Windows 10 is blurry on secondary monitors if they have a different DPI from the primary monitor. This is because Task Manager is only PROCESS_SYSTEM_DPI_AWARE, despite being a relatively new application (a new Task Manager was introduced in Windows 8). This can be confirmed by using a tool such as Resource Hacker and checking the manifest file for this:

<asmv3:windowsSettings xmlns="http://schemas.microsoft.com/SMI/2005/WindowsSettings">
    <dpiAware>true</dpiAware>
    <autoElevate>true</autoElevate>
</asmv3:windowsSettings>

How effectively delete a git submodule.

To remove a submodule you need to:

  • Delete the relevant section from the .gitmodules file.
  • Stage the .gitmodules changes git add .gitmodules
  • Delete the relevant section from .git/config.
  • Run git rm --cached path_to_submodule (no trailing slash).
  • Run rm -rf .git/modules/path_to_submodule (no trailing slash).
  • Commit git commit -m "Removed submodule "
  • Delete the now untracked submodule files rm -rf path_to_submodule
