Hey guys,
I did an update to the newest kernel version on my Thinkpad L520 today. Unfortunately, after a reboot I just get a blank screen when the system switches to the native display resolution via KMS. I added "i915" to my initramfs according to https://wiki.archlinux.org/index.php/In … modules.22 and disabled rc6 as well. Neither of this did solve the problem. Is there anyone with similar issues or an idea on how to fix it?
My graphics chip is an Intel HD 3000 (lspci: 00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09)) and I am using the most recent packages as of today.

It's working fine on
[karol@black ~]$ lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation 82845G/GL[Brookdale-G]/GE Chipset Integrated Graphics Device (rev 01)
but obviously it's a bit different hardware :-)
Does disabling KMS fix it?

The "Intel" wiki article says: "Versions 2.10 and newer of the xf86-video-intel driver no longer support UMS, making the use of KMS mandatory.". That made me assume that there is no way to disable KMS with my setup.

I think you need KMS for X, but not for the console but I don't remember checking it.

There is, but X won't work if you do it.

I just want to make sure it's KMS-related.

Yes, it is definitely KMS-related. I disabled KMS via i915.modeset=0 and now I am back in my system (console and GNOME 3 fallback mode for now). Are there any ideas on how to make KMS work again..?

I got the same problem with my L520, too.
Actually I can get graphical output on my external VGA display. The Laptop display itself is not working. This seems to be a kernel bug introduced in the recent 3.2 Kernel.
There is already a fix for this. I hope it gets pushed to one of the next releases.

So, I guess i'll be waiting for a new kernel release then...
Right now a downgrade to 3.1.9 fixed the KMS annoyance.

That's what I did. And yes, it's annoying but imagine we wouldn't even have the possibility of downgrading. Given the fact of always having the latest software on my computer, we (have to)accept that
So let's grab 2 (plus x) beers and wait

Arch Linux - rolling release distro, where people are wanting to downgrade to a previous version

Same laptop, same problem, let's hope this will be fixed soon.

I also have the same problem, Lenovo L420, mine boots with i915.modeset=0, but unfortunately with wrong resolution. Did all of you downgrade?
And as I never downgraded, whats the best way to do it?

I just took the package for the most recent version of Kernel 3.1 out of /var/cache/pacman/pkg and installed it with pacman -U. With my setup I had to remove virtualbox before but apart from that it was quite unproblematic.
For more information you can also refer to the corresponding wiki article at https://wiki.archlinux.org/index.php/Downgrade

Thanks, 2beers, I tried, but I get this error

You should try some more recent kernel, like linux 3.something.

Thanks, I was looking for "kernel" and not "linux" in /var/cache/pacman/pkg/.
Did it now, lets see will it work

I just tried Kernel 3.2.2-1.
It's not safe to upgrade yet...

The patch is submitted to the 3.2.3 source

I'm going to chime in real quick. I'm having the exact same problem but I have a Radeon HD 6870 and I'm using xf86-video-ati. I hadn't realized it started acting up right after I updated the kernel until I saw this thread. I'll post some more detail tommarow (On my laptop right now)
Should I create a new thread since this is different hardware?
Edit: I created my own thread

I just tried Kernel 3.2.5-1, but it is NOT safe to upgrade! So it seems that the patch isn't submitted. Does it works for you?

Hi,
I have exactly the same problem. Can you tell me how to apply this patch? I'm just new to Arch Linux and don't know how to do this unfortunately.
Thanks in advance.
