Comment 39 for bug 1735594

There's no way to withdraw an update other than by dropping the offending patch, but since I already have a replacement available we should test that instead.

And now that the PPA builds are finally back, please test this one on xenial:

sudo apt-add-repository ppa:tjaalton/ppa && apt update && apt upgrade

but if you have the padoka ppa enabled, it needs to be removed first:

sudo ppa-purge ppa:paulo-miguel-dias/pkppa

and if you installed stock xenial xorg stack, reinstall -hwe-16.04 by:

sudo apt install --install-recommeds xserver-xorg-hwe-16.04

remember to reboot or at least log out after installing the new mesa from my ppa
