Created attachment 136851 [details] dmesg output Screen goes black after switching to framebuffer, both in TTY and xorg. Backlight is working, changing brightness too. I can access xorg with x11vnc and even change display resolution/rotation/refresh rate (backlight blinks when I change resolution). Architecture: x86_64 Kernel: 4.15.0-1035f22af3e97, built with drm-tip from 01.17.18 Linux distribution: Arch Linux (doesn't work on Ubuntu 17.10 too) Machine or mother board model: Toshiba Satellite Click 10 (LX0W-C64 model), Cherry trail cpu, X5-Z8300 Dispay connector: DSI-1 (from xrandr output)

Well, I think this may be the problem: [drm:i915_gem_object_create_stolen_for_preallocated [i915]] failed to allocate stolen space If I comment out "if (ifbdev->vma)", like said in bug 104158, comment 28, and recompile the kernel, it will be about 50-50 chance for tablet to boot up normally, with image on screen, backlight regulation and video acceleration (it plays 1080p video from youtube). Also I can't boot up with "drm.debug=0x1e log_buf_len=4M" (always black screen), and it won't reboot or power off with this kernel (spams with "failed to unmount /oldroot/*" and hangs on "kvm: exiting hardware virtualization", maybe my fault somewhere) (And, well, is anybody here? It was about two month without any updates)
Hi, sorry for the delay but there is an unusual big list of bugs to work on right now so it may take some time, as you have already an idea of what could be going wrong, you could try to push this issue by using the dev's community channels or the forums to debug it: https://01.org/linuxgraphics/community
First of all. Sorry about spam. This is mass update for our bugs. Sorry if you feel this annoying but with this trying to understand if bug still valid or not. If bug investigation still in progress, please ignore this and I apologize! If you think this is not anymore valid, please comment to the bug that can be closed. If you haven't tested with our latest pre-upstream tree(drm-tip), can you do that also to see if issue is valid there still and if you cannot see issue there, please comment to the bug.
Bug isn't valid anymore
Thank you for feedback, closed
