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. --- ProblemType: Bug ApportVersion: 2.20.9-0ubuntu7.4 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: matt 1796 F.... pulseaudio /dev/snd/controlC1: matt 1796 F.... pulseaudio CurrentDesktop: KDE DistroRelease: KDE neon 18.04 InstallationDate: Installed on 2018-09-27 (0 days ago) InstallationMedia: neon devunstable "Bionic" - Build amd64 LIVE Binary 20180924-13:08 Lsusb: Bus 001 Device 002: ID 8087:8000 Intel Corp.
