description |
Colour bandind is visible everywhere in the system. I believe it's not a hardware problem, since booting with 'nomodeset' works as expected and the previously installed Ubuntu 14.04 also worked.
I tried installing kernel 4.18.0-16.17 from ppa:canonical-kernel-team/ppa but the problem remained.
There were already similar bugs, https://bugs.launchpad.net/bugs/1749420 , https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1794387 and https://bugs.launchpad.net/bugs/1788308, but the fixes provided for those bugs did not work for my specific monitor.
