Comment 6 for bug 1701873

Thanks for the update. I read through the page you recommend. This seems risky to me. I have -extra package installed. I don't know what will happen to my system if I uninstall them. Installing a kernel manually is not in my comfort zone. I prefer to automatically boot on the old one that risk to crash my whole system.

However, the workaround you proposed (sudo apt install --install-recommends xserver-xorg-hwe-16.04), works perfectly and I now have a more recent kernel that boot.

I still don't understand why the previous one freezed but since it was with an older version of the kernel this was later corrected.

Thanks for your time !
