Yes when the problem was first reported we had kernel 4.13, but now it is 4.15 which might have fixed it.
Since you are the original reporter we can declare this bug fixed. Anyone else who still has issues after updating to kernel 4.15 should file a new bug. ** Also affects: linux (Ubuntu) Importance: Undecided Status: New ** Changed in: linux (Ubuntu) Status: New => Fix Released ** Changed in: linux (Ubuntu) Importance: Undecided => High ** Changed in: gdm3 (Ubuntu) Status: New => Invalid ** Changed in: mutter (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/1748871 Title: GDM horizontal scanline corruption with an ultra wide monitor To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1748871/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
