I'm currently at kernel version 4.14.11 and the intel firmware drivers installed from https://01.org/linuxgraphics/downloads/firmware which are: kbl_guc_ver9_14.bin bxt_guc_ver8_7.bin kbl_dmc_ver1_01.bin
And the bug is still there. Although it wasn't manifesting itself until I've connected an external screen (may coincidence though). @Angelo Lisco Not sure will it help in your case but have you tried setting kernel boot flag? i915.enable_rc6=0 It's workaround not a fix, I'm afraid. -- 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
