Problem with file iris_dri.so

I need help, delete the file iris_dri.so because I confused it and now certain programs are much slower than usual. What I can do?

It should be clarified, I have Ubuntu 20.04

>Solution :

That library appears to be part of the libgl1-mesa-dri package, so you will need to re-install it to ensure you have all of your files.

You can do so from the Terminal like this:

sudo apt --reinstall install libgl1-mesa-dri

Try to be a bit more careful with the rm command, as there is not always a simple fix 😉
