Tested it yesterday. Had this bug with kubuntu 16.04.2 after kernel update and later on with an update to kubuntu 17.04.
With 4.12.0-041200rc4-generic #201706042031 graphics/KDE works fine, Installed the "all" headers and the kernel deb. but this specific error is still listed in dmesg: [ 3.872945] Console: switching to colour frame buffer device 160x50 [ 3.892060] i915 0000:00:02.0: fb0: inteldrmfb frame buffer device [ 5.137529] [drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU pipe A FIFO underrun -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1550779 Title: [i915]] *ERROR* CPU pipe A FIFO underrun - Xorg glitches To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1550779/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
