Description Denis 2017-03-25 07:47:52 UTC
Created attachment 130446 [details] dmesg from kernel 4.11.0-rc3 with drm-intel-next-2017-03-20 The screen is going black after switching to inteldrmfb. I`ve tested kernel 4.11.0-rc3 and 4.11.0-rc3 with drm-intel-next-2017-03-20, result is same. With kernel from Linuxium there is still black screen, but I can control brightness blindly (there is folder '/sys/class/backlight/intel_backlight', when in 4.11.0-rc3 in folder /sys/class/backlight there are 8 folders from acpi_video0 to acpi_video7). Kernel 4.8.x which goes with Ubuntu 16.10 is working fine, but there isn`t brightness control. I`ve also tested latest Arch linux with Gnome DE on wayland, same issue (Black screen even on TTY`s, without loading DE). Architecture: x86_64 Kernel: 4.11.0-041100rc3-generic Linux distribution: Ubuntu 16.10 Machine or mother board model: Toshiba Satellite Click 10 (LX0W-C64 model), Cherry trail cpu, X5-Z8300 Dispay connector: DSI-1, as Xrandr says.

Created attachment 130552 [details] dmesg from kernel 4.11.0-rc3 with kernel params from 96571
Comment 4 Denis 2017-03-29 20:21:39 UTC
It still won`t work with those kernel parameters. Dmesg: https://bugs.freedesktop.org/attachment.cgi?id=130552
Comment 5 Jani Nikula 2017-03-30 07:08:38 UTC
Please also try drm-tip branch of https://cgit.freedesktop.org/drm/drm-tip, there are some fixes that haven't made their way to v4.11-rc.
Comment 6 Denis 2017-03-31 08:54:25 UTC
Result with mainline 2017-03-31 Ubuntu kernel build is same, black screen and "*ERROR* Failed to own the pwm chip" in dmesg.

Please try this http://kernel.ubuntu.com/~kernel-ppa/mainline/drm-tip/2017-03-31/ and report results. It helps me with Dell Venue 8 Pro 5855.
Comment 9 russianneuromancer 2017-03-31 17:16:48 UTC
For some reason this build boot for me only with "drm.debug=0x1e log_buf_len=1M" kernel options. Without it tablet hang in the middle of boot process and then poweroff.
Comment 10 russianneuromancer 2017-04-01 07:47:16 UTC
I just noticed that you already tested 2017-03-31 build and it's doesn't help you. So your issue is different from mine. Sorry for noise.
Comment 11 Denis 2017-04-17 15:42:32 UTC
Created attachment 130877 [details] Dmesg from drm-tip 2017-04-16 I`ve built Ubuntu kernel with latest drm and config options from bug 96571. PWM error is gone but the screen is still black.
Comment 12 russianneuromancer 2017-06-16 05:53:20 UTC
Denis, is there no changes with current Linux 4.12 and current drm-tip?

Hello Denis, no new cases since April have been reported, is this still reproducible? Thank you.
