Bug Description
Colour bandind is visible everywhere in the system, and it appeared after I had my integrated monitor replaced. I believe it's not a hardware problem, since booting with 'nomodeset' works as expected.
There were already two similar bugs, https:/
I'm running Ubuntu 18.04 with kernel linux-image-
I attached the results of running
sudo get-edid | parse-edid in a file named edid.txt
sudo get-edid | edid-decode in a file named edid-decoded.txt
cat /proc/version_
sudo lspci -vnvn in lspci-vnvn.log.
