xorg.0.log in 3.7.3 kernel
It looks alive, so I think the issue is the backlight. Can you try for i in /sys/class/backlight/*; do cat $i/max_brightness > $i/brightness; done Thank you so much. It works. So its just a matter of adjusting the display brightness. But is there a possible way to set it up permenantly, so that I don't have to adjust the screen brightness manually everytime at boot. Ideally you want a more recent DDX so that you could either use SNA which I believe would select the right backlight in this case, or to make Option "Backlight" available in xorg.conf. For the time being, I would just put that single line into /etc/rc.local I 'll try that. Thanks for the suggestions. You are a great live saver. I am using fullly updated arch linux with recent xf86-video-intel Version : 2.21.2-1 But still the system cannot set the right backlight. Is there anything else I need to look into? Can you attach the Xorg.0.log from your recent update, after enabling SNA? Created attachment 74847 [details]

Looks like it happen in fedora too with another user having the same issue. http://forums.fedoraforum.org/showthread.php?p=1634465 Created attachment 74848 [details]

interface /sys/class/backlight/acpi_video1 SNA: [ 6.907] (--) intel(0): found backlight control interface acpi_video1 (type 'firmware') So the bad news is that your system is advertising acpi_video1 as the right backlight controller for your display, but it sounds like that it is the wrong one. Try something like acpi_backlight=vendor or acpi_backlight=legacy The bug sounds like it solely lies in acpi_video1 being dysfunctional and still claiming to be the right interface to use. acpi_backlight=vendor - works with screen brightness set to max, but I am not able to reduce screen brightness with gnome-control center. acpi_backlight=legacy - doesn't work. (In reply to comment #14) > acpi_backlight=vendor - works with screen brightness set to max, but I am > not able to reduce screen brightness with gnome-control center. > acpi_backlight=legacy - doesn't work. Hmm, mind satisfying my curiosity and pasteing the "found backlight control interface" line from Xorg.log for the various combinations of acpi_backlight and UXA/SNA? 7.039] (--) intel(0): found backlight control interface /sys/class/backlight/intel_backlight for acpi_backlight=vendor in uxa -backlight is set to max , can be adjusted manually 7.137] (--) intel(0): found backlight control interface /sys/class/backlight/acpi_video1 for acpi_backlight=legacy in uxa - backlight is set to zero, can be adjusted manually 6.872] (--) intel(0): found backlight control interface ideapad (type 'platform') for acpi_backlight=vendor in sna -backlight is set to max, cannot be adjusted manually 7.340] (--) intel(0): found backlight control interface acpi_video1 (type 'firmware') for acpi_backlight=legacy in sna -backlight is set to zero, can be adjusted manually Tbh, I think Codito ergo sum. I think the only way we can get this solved is to beat up a few ACPI firmware engineers and see if the various ACPI drivers can make any traction. Other than trying to follow the guidelines and picking the preferred backlight interface (multiple drivers suck) there is little else we can do in the gfx driver. Thanks for helping me sort this out. Shall I file a bug in linux kernel? Can you please test whether disabling the ACPI backlight ala https://patchwork.kernel.org/patch/2697681/ fixes the issue? I 'm not a programmer of any sorts, but saw the patch. Looked like it was looking for atom bios with radeon card. My system has insydeh20 bios with intel+nvidia card. Sorry if I got it totally wrong. (In reply to comment #20) > Can you please test whether disabling the ACPI backlight ala > https://patchwork.kernel.org/patch/2697681/ fixes the issue? Not this patch. hadrons123 tested patchset for unregister backlight and its work. But this bug remained.

Created attachment 73464 [details] dmesg in 3.7.3 debian kernel I am using Debian sid with Debian 3.7.3-1~experimental.1 kernel and since 3.7 kernel series my system boots into a black screen. I can however type commands blindly using the ttys. nomodeset gets me to debian gnome fallback. I tried other distros like Fedora 18 and Arch linux and had similar results with the 3.7 series kernels. I tried 3.8.rc4 mainline kernel in arch but had similar results. I am a physcian and I have no idea to bisect the kernel commits. Here is a list of attachments which might be useful. I would certainly post some log using the 3.8.rc4 kernel if you want. My machine is a Lenovo Y580 with a ivybridge intel HD4000 graphics setup.
