Linux configuration
To clarify, the flicker consists of three or four flashes, which lasts a good second or so. (In reply to Paul Menzel from comment #0) […] > Since building Linux 4.10 release candidates up to Linux 4.11-rc2+, I am also able to reproduce this with Linux 4.9.x shipped by Debian 9 (Stretch/testing). […] Hello Paul, There seem to be firmware related problem ... Mar 17 13:23:11.783611 xps13 kernel: i915 0000:00:02.0: Direct firmware load for i915/kbl_huc_ver02_00_1810.bin failed with error -2 Mar 17 13:23:11.783727 xps13 kernel: [drm] Failed to fetch valid uC firmware from i915/kbl_huc_ver02_00_1810.bin (error -2) Do you have the ver02_00 firmware installed in your system? If not then please update firmware from https://01.org/linuxgraphics/downloads/kabylake-huc-2.0 and see if problem still persist.

The description of the firmware seems totally unrelated. > HuC is a dedicated firmware for usage in media HEVC (High Efficiency Video > Coding) operations. Userspace can use the firmware capabilities by adding HuC > specific commands to batch buffers. How can this be related? Sorry Paul, about the delay for getting back to you. HuC loading was the only thing that was jumping out from dmesg. Does problem still persist with latest drm-tip? If yes, please attach dmesg and Xorg.0.log from the system and change the status to REOPENED. Paul - please help us here and give update: Still valid with the latest kernels (preferable from drm-tip)? If yes, please attach dmesg and Xorg.0.log from the system and change the status to REOPENED. If not reproducible then please mark this as resolved.

Hello, Still no answer on this case, so I'm closing the bug. If the problem persist with the latest kernel version, please open a new bug and share the information. Thanks. |

Created attachment 130286 [details] Linux messages (output of `journalctl -k -o short-precice`) Since building Linux 4.10 release candidates up to Linux 4.11-rc2+, the screen of the Kaby Lake device Dell XPS 13 9360 heavily flickers during start-up on the console, and sometimes the screen isn’t turned on at all after the driver i915 is loaded. The backlight seems to be on though. Often, a workaround is to suspend the system by pressing the power button, and resuming it. Then the display is turned on. Please find a log attached.
