Thank you for your quick response! This regression / bug was found out almost 2 YEARS ago: https://bbs.archlinux.org/viewtopic.php?id=225215 and a patch was sent to upstream (see post #2), but apparently it was never pulled.
Regarding hex vs dec, the file in master they seem to be mixing both: https://github.com/torvalds/linux/blob/master/drivers/gpu/drm/drm_edid.c The product id number for a specific panel is found in Xorg.log: fgrep EDID /var/log/Xorg.0.log [ 751.496] (II) modeset(0): EDID vendor "SDC", prod id 18514 Anyway, I am hoping that Ubuntu, which has the biggest base of desktop Linux users (and in particular of people who may have bought laptops without pre-installed Windows, like Lenovo G50-80 and G50-70), would choose to fix this regression for Ubuntu users. ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1819968 Title: Colour banding in Lenovo G50-80 laptop display (i915) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1819968/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
