black screen after boot


Hi,
I am experiencing a weird problem with my dell latitude laptop. I installed debian amd64 once with gnome and after grub it echoes the following message:
Code:
Unknown controller version (2). You may experience  problems.
and after the /dev procedure my screen (16:9) goes black.

After that I tried to reinstalled debian without gnome and I booted to shell. From there I installed manually (apt-get) gnome and started gdm3 and I my screen was ok, but after I did a reboot the same problem happened. Also, when I boot with an external VGA monitor, the vga looks ok but the laptop screen is still black.

output of lspci | grep -i vga
Code:
00:02.0 VGA compatible controller: Intel Corporation Core Processor Integrated Graphics Controller (rev 02)
any help would be appreciated!
Thx in advance!



EDIT: I just realized another strange thing. If I boot without the vga plugged, I get the usual black screen and when If I wait and understand that I am in the login screen and at this time I plug the vga, then miraculously my laptop screen works fine!!! But later on if I close the laptop lid and open it again, then again ... black screen but if I plug the vga it's ok again!!! This thing drives me mad...

A 16:9 monitor won't run on vesa.

Have you xf86-video-intel installed?

no. where can I find it? I cannot apt-get install it. is that the actual name of the package.

but in any case how is it explained that I have an output in my laptop after plugging the external monitor? now I am writing this post from my laptop screen.

I found xf86-video-intel and installed but unfortunately no progress.

Any other ideas please? I insist that this is very weird, the driver seems to work ok only when it is triggered by a vga cable and then unplugged... :~

I missed this bit. That's a kernel issue. When you add in this

It pins it down. The kernel is not recognizing your card/monitor, perhaps because vesa is compiled in - I'm no debian expert. Try google. I quickly found this
blank screen latitude intel +debian

When you search, put in your pc model number, and the number of your graphics card, the version of debian and kernel number and you will get a specific answer.

yes but how can my kernel does not recognize laptop card/screen, while I am able to use this screen when I just connect an external monitor and immediately disconnect it. in this case I have output in my laptop screen.

I have made a lot of googling but nothing so far. the bug you posted is not the same problem.

anyway thanks for your time.

you need to post more specific model information
1. here
2. in google, and see if anyone else has hit this. You are hardly the first latitude owner running debian.

It's some crappy intel graphics setup. What's remarkable about it is what they don't say - no model number, no specs (directx-10.x, opengl-2.x).

Your chip id would be 8086:0046; check that with lspci -n. Then go to www.google.com/linux and google 8086:0046
Here's two from the first page of that.

This way, you'll find what worked for others

I tried that but no solutions found. there were similar problems withous soloutions and problems with solutions were not relevant with mine.

I did another install (of wheezy this time) and boot ok without X support. then from terminal I did apt-get install xserver-xorg-core, switched nice to graphics mode but after that on reboot same problem again.

I am trying to compile xf86-video-intel (version 2.9.1, most recent didn't work out) just in case but I am not optimistic

I did a small progress, although no solution yet. I found out that the problem is on KMS (Kernel Mode Setting, I don't know exactly what this does, anyway). I disable this (/etc/modprobe.d/i915-kms.conf) and while prior to that, after the black screen was showing up after the message "waiting for /dev to populated", now it continues but just before the login screen it shows a blinking cursor in the left corner and nothing happens (I noticed though that the disk button lights imperceptibly).

Does this gives extra information for someone to help me?

Finally, I managed to find a workaround by installing the liquorix kernel (2.6.38-2.dmz.1-liquorix-686)

My next target is to make microphone work!


Thx to everyone!!!

KMS is Kernel Mode Setting.

You can usually disable it with a module option (quick google)
Add this to your boot line
i915.modeset=0

I know what it means, I just don't know what it does :P

I have tried that and many other tricks but nothing worked (flickering cursor). As I said before) I disable it through /etc/modprobe.d/i915-kms.conf (options i915 modeset=0). The boot option doesn't work for new systems.

Anyway the screens with the new kernel (http://liquorix.net/) works without any problems for now.

It passes an option to the module for bootup. I'm using
kernel /vmlinuz-2.6.35.4-agp ro root=/dev/sda6 ro radeon.modeset=1

to Enable kernel modesetting here. =0 simply disables it.
