Arch Linux

I tried running without KMS, and that lets me get to the KDM screen, but it will crash immediately right back to the KDM screen after putting in my password.

Downgrading to kernel 2.6.35 fixes this for me, so this must be something in the new kernel.

the intel driver doesn't support UMS mode anymore. you must use KMS mode. then report full logs (dmesg/Xorg.0.log).

How do I change from UMS to KMS?

I followed the directions in the link, and it did not make a difference.

I'm really confused about this, because I have been using KMS since before this latest kernel was released. It allows me full resolution in TTY's and I use that a lot. I don't know why it's reporting that I'm not using KMS, because I am, and have been.

please add "verbose" to your grub kernel append line to get usefull output. please use KMS late mode to avoid mkinitcpio issues.

Here is the updated dmesg file after running verbose. Please note that I already run late start kms, as I believe it is the default. (I created this system after kms went mandatory, and use whatever is the default now days).

I did some further experimenting today. I grabbed a spare hard drive, and installed Arch on it with the latest install media. I did not install X, any drivers, or applications. I only installed core. After installing, I did a -Syu and rebooted. Same problem.

I have the same issue.
I had to downgrade my kernel and intel driver to post this.

In my case however, the laptop would boot and then take maybe 45 minutes till X would start, then I would unlock it (I use openbox and xscreensaver set to lock) and then it would lag severely and nothing but moving the mouse would work.

Attached are log files from my current boot, I can test the updated packages in a day, I have work to do :)

I also want to add that with using 2.6.35 and all of the latest Intel packages, KWin crashes almost every time I exit a full screen game.

same problem here.

I also tried the latest kernel26-git, here I get a picture after KMS turned on, but it's flickering all the time. Not usable if you ask me.

Same problem with dark screen here on a HP ProBook 5320m, Core i5 integrated graphics.

The screen goes black as soon as i915/intel_agp is loaded (either in initrd or userland). Booting with i915.modeset=0 works, but of course only with xf86-video-vesa (and wrong DPI).

Downgrading to kernel26-2.6.35.8-1 works, so this is a kernel26 issue, not xf86-video-intel.

I agree about it being a kernel bug. I'm the one that filed this bug initially but I don't know how to remove xf86-video-intel from the description. :(

am on ibm thinkpad r51. during the bootup when the udev events are being processed, screen goes black and keyboard goes dead, i have to hard shutdown. downgrading to kernel26-2.6.35.8-1 works.

Alright! After a few hours building kernels and bisecting, for me it all comes to this commit:
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=7643a7fa16edf180d593f705f4fa5930c40e8d2d

I created a patch to revert this commit and build a working 2.6.36 kernel.
My hardware is a HP ProBook 5320m, I don't know if the same patch will work for you as I read some bug reports that it's often very hardware specific, as there are lot of reports with blank screen after KMS init.

Would be nice if someone else could test this patch.

I would be more than happy to try the patch, but I'm a newbie when it comes to patching and I don't know how. I'll see if one of my colleagues is available tonight to help me patch it.

Rene, please report it upstream!

already done: https://bugs.freedesktop.org/show_bug.cgi?id=32005

I created an AUR package which builds the kernel 2.6.36.1 with this patch.
http://aur.archlinux.org/packages.php?ID=44045

the package isn't tested to much so don't expect to much.

The patch you posted works, but has an undesired effect.

First of all, I am typing this from the patched kernel that Rene posted. This is more than I was ever able to do before. I am able to log in and use my machine. In addition, my card reader works now, and it didn't work in 2.6.35.

On the downside, tty's don't work. When I boot up, most of the boot process is a blank black screen, but the difference now is that X starts and I can use my laptop but tty's don't work.

Good job though! All we have to do is restore tty access and I'm good as gold.

I don't know if it will help but did you try to load the i915 early, during the bootstrap?
Instructions how to do this is here: https://wiki.archlinux.org/index.php/Intel#KMS_.28Kernel_Mode_Setting.29

That's actually what i was already doing. It doesn't seem to make a difference.

kernel26-intelfix appears to work properly on this HP ProBook 5320m.

What are the chances of this patch making it in the actual kernel? Other than not being able to access tty's the patch works wonders, and makes an unusable system usable.

On above HP ProBook, I can access the TTYs with kernel26-intelfix as usual (as with 2.6.35).

That seems to be an unrelated regression.

I have a seemingly similar problem (blank screen on lcd for intel graphics when kms kicks in on 2.6.36-line kernels), but 2.6.36.1 intelfix doesn't fix it.

I have a Sony Vaio Z series laptop (vpcz1) with switchable Intel Core i5 graphics/nvidia graphics set to work with static graphics switching. Booting with only the intel card enabled under 2.6.35.8 works fine. Under 2.6.36.1 from arch (or 2.6.36.1 from AUR's kernel-intelfix, and at least as far back as 2.6.36-rc1 from kernel.org) the embedded LCD screen goes black (no backlight) as soon as KMS starts. It doesn't change whether or not I have X enabled, the screen just stays black.

I can't really help you fix these problem as I can't reproduce this on my hardware, but you could also try to bisect the problem to specific commit. It is a bit of pain and takes time, but try to build 2.6.36-rc1, because between rc1 and rc2 there where some commits which might possible the reason.
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=shortlog;h=refs/tags/v2.6.36-rc2
Here the drm/i915 commits are the hot ones. if rc1 doesn't work for you, you would need to check even more between stable 2.6.35 and 36-rc1.

Quick question. I am still unable to access tty's in the patched 2.6.36 kernel. I know that it's perceived that it is a separate issue, however I recently downgraded the Intel driver to the previous version and I still cannot access tty's. Is it possible it's related to this issue? Or should I file a separate bug report for it?

I tried 2.6.36.2 today, and the problem is still not solved.

Having similar type of problem with intel 855GME. The screen wents sometimes total blank and wont change to other terminals. It falls back to 1024x768 if i can get picture. Also finds only 1024x768 resolution with vesa driver which i kinda of odd. Not related to xf86-video-intel ?

It looks like this bug was fixed upstream:
https://bugs.freedesktop.org/show_bug.cgi?id=29278

I know this is asking a lot, but can this fix be implemented into the Arch kernel? If not, is it possible for an AUR package to be made consistent with the patches found in that bug report? I would do it myself but I am not currently at that skill level.

I still have the issue with the latest kernel and intel packages. Anything I can do? I currently run an old kernel because I am forced to...

With 2.6.37 I have a different issue. I can see a picture but have heavy flicker. I already reported this upstream and it was fixed in the drm-intel-staging branch, which I'm currently using (with 1 revert because of another black screen bug....)

Your only chance is to report the bug directly to the intel developers and pray that they will backport a fix for the 2.6.37 kernel.
