I remember one time I installed a lot of themes for my session and I broke something and the themes changed my icon files forever and I had to reinstall Ubuntu!!
Should I just stick to changing my wallpaper and other small tweaks? I don’t really like using vanilla Ubuntu anymore, it doesn’t feel like me. Thank you very much!!
Why don’t you chill out about your Linux setup a bit, and instead of doing stuff to your Linux system, do stuff with it.
Open Source software lives from the contributions of the users, and there’s plenty to do everywhere.
You could use your free time to actually make a difference and help out other Linux users!
