On my Pentium N3710 based notebook the X server does not start anymore too. I made some investigations, and i guess its because after the patch another crtcs is choosen for the desired mode. Before the patch intel_fb_initial_config always returned false, and drm_setup_crtcs is choosing crtc 46:pipe A which is fine for the X server. [drm:intel_fb_initial_config [i915]] Not using firmware configuration [drm:drm_setup_crtcs [drm_kms_helper]] looking for cmdline mode on connector 91 [drm:drm_setup_crtcs [drm_kms_helper]] looking for preferred mode on connector 91 0 [drm:drm_setup_crtcs [drm_kms_helper]] found mode 1366x768 [drm:drm_setup_crtcs [drm_kms_helper]] picking CRTCs for 8192x8192 config [drm:drm_setup_crtcs [drm_kms_helper]] desired mode 1366x768 set on crtc 46 (0,0) Now intel_fb_initial_config is returning true, but is choosing crtc 63 instead, and with crtc 63 the X server doesn't come up [drm:intel_fb_initial_config [i915]] looking for cmdline mode on connector eDP-1 [drm:intel_fb_initial_config [i915]] looking for preferred mode on connector eDP-1 0 [drm:intel_fb_initial_config [i915]] connector eDP-1 on [CRTC:63:pipe B]: 1366x768 [drm:intel_fb_initial_config [i915]] connector DP-1 not enabled, skipping [drm:intel_fb_initial_config [i915]] connector HDMI-A-1 not enabled, skipping [drm:intel_fb_initial_config [i915]] connector DP-2 not enabled, skipping [drm:intel_fb_initial_config [i915]] connector HDMI-A-2 not enabled, skipping [drm:drm_setup_crtcs [drm_kms_helper]] desired mode 1366x768 set on crtc 63 (0,0) So probably the patch itself is correct, but it breaks a previously running system, and i do not see any progress in the X server about an atomic commit.
