Kernel mode setting

Hi,

I recently performed a full system update, but I've run into problems regarding the kernel (according to xorg/intel anyway). The boot process is fine because it changes to native resolution (I assume this is the new kernel at work with KMS), but when it comes to executing X it crashes (it doesn't tell me why, and I can't find anything in the logs telling me why). So I tried configuring a new X configuration file by using:

Xorg -configure

This threw back an error, but created a configuration file none the less. According to xorg this is the problem:

(EE) intel(0): No kernel modesetting driver detected.

How can this be if I'm successfully booting up with native resolution? I believe that is the KMS driver at work. Everything is up to date -- I even enabled the testing repository to see if it's fixed in an up coming package, but that didn't work. I don't know why it's complaining about no KMS driver, even though I obviously have one if I'm running at native resolution outside of xorg.

I'm using the Intel 945GM chipset with Intel GMA 950 graphics. I have set 'intel_agp' and 'i915' in the 'mkinitcpio.conf' module section.

Re: Kernel mode setting

What does 'pacman -Qqs intel' show?

When was the last you did an update? KMS for intel isn't exactly new.
Are you using testing or not? Testing uses xorg 1.8 and extra has still xorg 1.7 - and there are major differences between the two.

Re: Kernel mode setting

Pacman query shows:

intel-dri
xf86-video-intel

Last time I updated was ages ago before all this KMS (I believe it wasn't long after 2009.08). And I'm using testing, but that has not helped. I've hooked the computer up to the Internet, hence the updates.

Re: Kernel mode setting

So you did this

Change the MODULES and FILES lines in /etc/mkinitcpio.conf to look like this:
MODULES="... intel_agp i915"
FILES="... /etc/modprobe.d/modprobe.conf"

What's the output of those two:
'sudo cat /sys/module/i915/parameters/modeset'
'cat /etc/modprobe.d/modprobe.conf | grep modeset'

Re: Kernel mode setting

The result for the first command is 1. Second one is nothing because I didn't alter the modprobe.conf file because I added 'i915.modeset=1' to GRUB.

EDIT: It does look like I'll need to downgrade, but if anyone has any information or potential fixes, I (and perhaps many others) would still appreciate it.

Re: Kernel mode setting

Does your X start without a xorg.conf file?
