The addition of that kernel parameter does not change the lack of output in dmesg. Please file new i915 bugs at the freedesktop.org bugzilla: https://bugs.freedesktop.org/enter_bug.cgi?product=DRI&component=DRM/Intel |
Created attachment 202891 [details] Xorg.log I am running 4.4.1 on Arch x86_64 and have noticed that this update (coming from 3.4.5) causes breakage of Xorg where the monitor goes to sleep but does not wake up from the sleep state. I have to `systemctl restart display-manager` in order to revive the Xorg display. I attached my full /var/log/Xorg.log but the error is shown below and there is nothing relevant in the output of dmesg: (EE) intel(0): sna_mode_shutdown_crtc: invalid state found on pipe 0, disabling CRTC:21 This machine is an Intel i7-4790K (Haswell) using the onboard graphics chip connected to the monitor via HDMI. I am using the distro provided drivers (xf86-video-intel 1:2.99.917+519+g8229390). I am glad to provide additional debug info upon request. I have just rebooted using the 'drm.debug=14' kernel parameter and will update the report if I am able to uncover any helpful troubleshooting data with it.
