I cant turn all the way around, or down or up.

So, I use linux java and one time my chromebook shut off and I had to reinstall linux. A bug started where I cant look up, down or all the way around. It ends where my computer ends and there is nothing I can do to fix it. I can press esc and the back to game but I do that so mush it get TOO annoying. The bug also makes me sometimes accidently ex out of minecraft, and much more. Please help
