Public bug reported: 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://bugs.launchpad.net/bugs/1749420 and https://bugs.launchpad.net/bugs/1788308, but the fixes provided for those bugs did not work for my specific monitor. I'm running Ubuntu 18.04 with kernel linux-image-4.15.0-34-generic, installing linux-image-4.18.8 with UKUU didn't help. 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_signature in version.log sudo lspci -vnvn in lspci-vnvn.log. ** Affects: linux (Ubuntu) Importance: Undecided Status: New ** Tags: amd64 bionic kernel-bug visual-quality ** Attachment added: "edid.txt" https://bugs.launchpad.net/bugs/1794387/+attachment/5192930/+files/edid.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1794387 Title: Colour banding in HP Pavilion 15-n233sl integrated display To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1794387/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
