Hi there,
I'v been using my Arch-system for quite some time now, but I haven't gotten to get kms to work.
Here's some info:
dmesg:
agpgart-intel 0000:00:00.0: Intel Mobile Intel GM45 Express ChipsetXorg.0.log:

(--) RandR disabled...I'm using xf86-video-intel-git-20090807-1-i686 from AUR, added intel_agp and i915 to the modules section of my mkinitcpio.conf, added "options i915 modeset=1" to the modprobe.conf and rebuilt my initrd.
Everything boots up and seems to work, but the screen stays blank/black. Only way to get the system back is rebooting blindly.
Did I miss something or is it my hardware not supported? Couldn't find out anything about this specific chipset. I'm using an Asus X5DIJ laptop, pretty new model afaik.
thanks,

xf86-video-intel-git-20090807-1-i686
did you try the extra/xf86-video-intel ?
i have no issue with same video chipset and kms active
added intel_agp and i915 to the modules section of my mkinitcpio.conf, added "options i915 modeset=1" to the modprobe.conf and rebuilt my initrd.
i did the same
lspci -v

I have the desktop version of the chip and it works ok. However, I also have "drm" in the modules section of /etc/mkinitcpio.conf, though I'm not sure it's necessary (the wiki doesn't mention it). Also, i boot with i915.modeset=1 added to my kernel line in /boot/grub/menu.lst, not with the modprobe.conf option (by the way, make sure you have no vga= or video= lines in /boot/grub/menu.lst).

Thanks for your replies, it seems to me as if the problem is related to the Laptop's display not being adressed correctly. I can view the Xorg logs and even browse the web "blind", I'll try to use my external screen to see if that works. Do you know of any parameters I could possibly pass to i915 instead of just "modeset=1" to narrow down the problem?
Of course, if I use VGA=9 arch boots fine with 1024*786 or something, but without KMS of course.
Thanks for your ideas anyways, I'll try using the kernel-option and report back.
btw: there's no difference between extra/xf86-video-intel and the git-package from AUR, UXA is working fine too, referring to the Xorg.log.old posted before.

Ok, using an external monitor via VGA works.
dmesg gives me some i915-related error-messages:
[drm] Initialized i915 1.6.0 20080730 for 0000:00:02.0 on minor 0
i2c-adapter i2c-2: unable to read EDID block.
i915 0000:00:02.0: DVI-D-1: no EDID dataThe problem should be the built-in display's incorrect EDID data, right?
Does anyone have a clue how this could be fixed/hotfixed/worked around?
btw: the kernel option results in "Unknown boot option `i915.modeset=1': ignoring", using 2.6.30-ARCH

Strange. So how do you normally set the screen resolution when not using KMS? Do you need to provide an /etc/X11/xorg.conf with the right parameters? If you try to boot without /etc/X11/xorg.conf does it also results in a black screen (I mean without KMS)?
What does "xrandr -q" say?
Also strange the boot parameter gives that error, it works here (maybe because of drm being included in the initrd image?).

I believe the kernel-option only works if you have i915 compiled into the kernel, not if it's loaded as a module.
xrand -q returns
Screen 0: minimum 320 x 200, current 1366 x 768, maximum 4096 x 4096
VGA disconnected (normal left inverted right x axis y axis)
LVDS connected 1366x768+0+0 (normal left inverted right x axis y axis) 344mm x 193mm
1366x768 59.6*+
1024x768 85.0 75.0 70.1 60.0
832x624 74.6
800x600 85.1 72.2 75.0 60.3 56.2
640x480 85.0 72.8 75.0 59.9
720x400 85.0
640x400 85.1
640x350 85.1
HDMI-2 disconnected (normal left inverted right x axis y axis)Apears to be correct to me.
I'm not using a xorg.conf at all, though I do use vga=9 to set my ttys to 1024*768, but I removed that to enable KMS.
I also tried an initrd with/without the drm module. The screen always turns black during bootup, when drm/i915 is loaded. The backlight stays on and can be adjusted using the fn-keys...
It's not like this is a showstopper, but afair using kms increases the overall performance/smoothness of UXA.

I realize the thread is a bit old, but for the record:
Same problem bugged me too, found this bug (ubuntu/fedora). Seems like it got submitted upstream, KMS now works like it should with 2.6.32 rc.
