[PARTLY SOLVED] Black screen on Intel GPU based laptop after update

Hello,

I performed system update after some time (2-3 weeks) and now when booting (after GRUB) screen goes blank. I don't see any systemd output and GDM. I rebooted computer and disabled KMS by via GRUB command line (I added "i915.modeset=0"). I at least have usable command line (in low resolution) but I'm not sure how to fix this problem. systemd claims, that GDM service is running, but I don't see any Gnome 3 desktop under seventh console.

Is it kernel o Intel driver issue? or maybe something else...

If it's not already there, what happens if you add the following to the kernel line:

acpi_osi=Linux acpi_backlight=vendor

That made mine work!

Didn't help. I'm almost sure it's somehow connected to Intel driver. For very short period of time I see initial kernel boot logs, then screen goes black.

Any other idea?

You could try the following on the command line (combined with mrunions suggested kernel parameters):

setpci -s 00:02.0 F4.B=00

The easiest thing would be to SSH into the machine and execute the above command as root. Be careful with this command, please read the backlight wiki page first.

Uh, I wasn't precise, I'm able to control LCD backlight, because I see it getting lighter or darker when setting it using keyboard shortcut. The problem is that I don't see any graphic/fonts etc., screen gets black just after few lines of kernel init logs and it stays like this.

Here I provide dmesg output:

Re: [PARTLY SOLVED] Black screen on Intel GPU based laptop after update

Partly solved, I figured out it's a kernel bug. I downgraded from current kernel (3.5.3) to version 3.4.8 and everything works fine.
