Booting from GRUB into 4.14.59 allows my two monitors to run at their native resolution, 2560x1440. Any newer kernel does not allow my two monitors to run at their native resolution, only allowing up to 1920x1200. uname -a Linux blackbox 4.14.59-041459-generic #201807280929 SMP Sat Jul 28 09:32:10 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux ** Affects: linux-meta (Ubuntu) Importance: Undecided Status: New ** Attachment added: "xrandr_4.14.59.log" https://bugs.launchpad.net/bugs/1799613/+attachment/5204715/+files/xrandr_4.14.59.log -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1799613 Title: In kernel 4.14.59, monitor resolution is detected correctly.
