Hi, Sorry for my bad english and my first bug is not good. I have an Acer laptop with an I915 Intel (Mobile Intel 4 Series Express Chipset Family) All distributions i try i have my monitor showdown (full black) after loading. I try : Mandriva 2011 Mageai 1 & 2 Fedora 16 Ubuntu 11 I try vesa on mageia, i can run but gnome 3 is restricted mode :( I have report this bug (i put link) on mageia the : 2011-06-15 after 1 year, i can't use Linux :'( Please someone can fix ? Thank you Arnaud
To clarify: Is this a problem with an external monitor or the build-in laptop panel? Also, please try with the latest 3.5-rc kernel. If that does not help, please attach drm.debug=0xe to your kernel cmdline and attach the full dmesg to this bug report. Also, please attach xrandr --verbose.
Hi, i think i have the same bug on the new macbook air 5,2 (mid 2012). When udev runs and loads the i915 driver the screen flickers short and then turns black (two seconds without backlight, than the backlight turns on again) I found a way around the bug: if i add i915.diescreaming=1 to the kernel line (found this hint somewhere in the internet) it prevents the i915 to start and the efi framebuffer does the rest. Using xf86-video-fbdev i'm also able to start X. I also noted that if i plug an external monitor to the thunderbolt/minidisplay port that (booting without i915.diescreaming=1) the display gets on, right after the internal display turned off, but with the resolution of the internal display. I tested this with the 3.4.4 kernel (Default Archlinux Kernel) and the 3.5 mainline kernel. With both happens the same. I will attach the messages.log (started with the drm.debug=0xe paramter) and a lspci -vvvnn. I hope my information is helpful!
Created attachment 74441 [details] messages.log booted with drm.debug=0xe
Created attachment 74451 [details] output of lspci -vvvnn
Dominik, you most likely have a completely different bug - there are gazillion ways we could fail to light up the screen and safe when you have an exact match on the model we need to wait until the issue is fully diagnosed before we can mark bugs as duplicates. Please open a new report for your issue, thanks. [Aside: Booting with i915.diescreaming=1 simply disable kms because this unknown module option prevents the intel driver from loading.]
hi, I come back today I install Mageia Caludron (v3) with 3.5.0 kernel on my computer (laptop Acer Aspire 573Z) and it is still blackscreen, i must use xdriver vesa for running but i can't use 3D :( Sorry i am french my english is poor and i am not expert in linux :(
fixing here : http://crashcourse.ca/blog/2011/02/workaround-intel-i915-black-screen-linux-boot-problem but i am newb for that lol thank you for fixing this issue, i can use 3D desktop / bad color and size with xorg
Not fixed in 3.5.2

Arnaud, please try i915.invert_brightness=1 module parameter with kernel version v3.5 or later, see if that fixes the brightness issue, and report 'lspci -vmmnn' if it does.
Ping for the information Jani request ...
Ping. Arnaud, please provide the requested information.

My hunch is that this is a gen4 Acer that requires the inverted brightness quirk. However we haven't heard from the reporter in about a year, and don't expect to get a tested-by. Closing.
