Same issue on Dell XPS 13 9343. Running Arch Linux, 4.4.5-1-ARCH, x86_64.
$ pacman -Q | grep xf86-video-intel xf86-video-intel 1:2.99.917+604+gff0ab2c-1 $ pacman -Q | grep xorg-server xorg-server 1.18.3-1 Things went better when I upgraded from 1:2.99.917+587+gc186d4d-1 to 1:2.99.917+604+gff0ab2c-1 (flickering was making my laptop just unusable). But still it happens, although less frequently. dmesg log lines when the issue occurs: [ 7780.306704] [drm:intel_dp_link_training_clock_recovery [i915]] *ERROR* too many full retries, give up [ 7824.405766] [drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU pipe A FIFO underrun [ 7865.757760] [drm:intel_dp_link_training_channel_equalization [i915]] *ERROR* 5.4 Gbps link rate without HBR2/TPS3 support -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1554613 Title: screen flickering on XPS13 9350 To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1554613/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
