Setting up a storage device as a Steam drive

• Create a mount point for the drive (Eg: /mnt/Games-SSD1). Ensure the ownership of this directory is $USER:$USER
• Use the blkid command to get the device's UUID (Eg: sudo blkid /dev/sda1)
• Add the following entry to /etc/fstab:

  UUID=<UUID>  /mnt/<MOUNT_POINT>  <FILESYSTEM>  user, data=writeback,defaults,exec,noatime,nofail,barrier=0  0  2
  

• After saving the file, the drive can be mounted and selected as an additional storage drive in Steam.

Fix broken rendering in Chromium-based browsers and Electron apps (Wayland)

• This issue usually occurs when the application's GPU cache is broken. To fix this issue, we can simply clear the GPUCache directory for the application.
• For example:
  • Google Chrome: rm -rf ~/.config/google-chrome/Default/GPUCache
  • VS Code: rm -rf ~/.config/Code/GPUCache
  • Brave Browser: rm -rf ~/.config/BraveSoftware/Brave-Browser/Default/GPUCache
• Restarting the application(s) after this should rebuild the GPU cache, and ideally, the issue should be resolved.
