[GAVE UP] xf86-video-intel does not recognize 945GM/GMS graphics

kjans · 2014-12-03 12:07:13

Hi!
My laptop died yesterday, so I took an half of an old laptop from the self and decided to make some kind of a temporary desktop-thing out of it. Basically it has no screen connected and I am using it with an external monitor that is connected to the VGA port.

It seems to have an Intel 945GM/GMS graphics card
lspci | grep VGA:

00:02.0 VGA compatible controller: Intel Corporation Mobile 945GM/GMS, 943/940GML Express Integrated Graphics Controller (rev 03)

Yesterdy I installed Arch on it (so it's a fresh and up-to date system):

xf86-video-intel 2.99.916-3

My problem is that X does not start and says that no devices were detected.

X starts without any problems with the VESA driver, but like you would expect, the performance is terrible...

Also, I don't know if this is connected to the problem or not but I had to disable graphical terminal in /etc/default/grub by commenting out the line

GRUB_TERMINAL_OUTPUT=console

as otherwise my screen was just black while in GRUB and I was unable to see the menu.
I haven't added any additional kernel parameters either, even removed "quiet", but this shouldn't matter I guess...

Anyway, If you require some additional information, I will be grad to add it.

First thing to do is try the LTS kernel. Second thing, open a bug report at bugs.freedesktop.org, as this looks like a problem only Intel developers will be able to help with.

headkase · 2014-12-03 13:07:36

See: Here, read "Phantom Output."

That page is for nouveau but the kernel line parameters it gives can be used with your intel hardware as well - they take effect before any drivers at all are loaded. What you want to turn off are "LVDS-1" or similar: whatever xrandr tells you it is called. The "-1" part might or might not be needed. Once that output is disabled at the kernel level then hopefully you'll be able to get the external screen working with the proper intel driver.

Please post back the results.

Edit: Also, the X error log is complaining about not being able to use modesetting. If you have any "VGA=" or "nomodeset" or similar in your kernel line then remove those too as they will also disable modesetting and that will also cause the intel driver to fail. And, hey, just noticed the kernel output controls are listed on the intel page: too.

LTS kernel did not solve the issue.
I do not have any "VGA=" or "nomodeset" in my kernel command line
Will look into the phantom output thing when I get back home, although with the VESA driver xrandr does not list the outputs for some reason...

xrandr: Failed to get size of gamma for output default
Screen 0: minimum 640 x 480, current 1280 x 1024, maximum 1280 x 1024
default connected 1280x1024+0+0 0mm x 0mm
   1280x1024      0.00* 
   1024x768       0.00  
   800x600        0.00  
   640x480        0.00

This actually made me think that as I still have the internal screen, but it's physically broken and thus unusable, maybe it would be a good idea to reconnect it, at least for the debugging purposes.

I'll keep you posted

headkase · 2014-12-03 13:30:03

If it's not getting picked up then try disabling the "LVDS-1" screen. That is, usually, a laptops internal screen. If "LVDS-1" doesn't work then try again with "LVDS". I hope it works, because it would just be awesome to have Linux in general rescue an otherwise dead laptop.

Gusar · 2014-12-03 13:37:45

For output names, look at /sys/class/drm, you will see directories like card0-VGA-1 in there. In this example, VGA-1 is the output name. The internal display will probably be LVDS-1, like headkase says, but looking in /sys/class/drm you will know for sure.

That the VESA driver will not show output names is normal, it's a generic driver with very few capabilities (it can't do native modesetting, it can't do multi-monitor, or anything fancy like that).

kjans · 2014-12-03 21:17:32

Ok, made some tests.
First: there is nothing interesting in /sys/class/drm. Only one file called version... which, as you might guess, contains the version info for DRM.

Secondly: tested this Phantom Output thing. Used LVDS-1, LVDS-0, LVDS... nothing.

I even tried to add i915 and intel_agp modules to the initramfs... nothing changed.

However, I looked a bit more into dmesg and found another interesting thing:

So it seems there is a problem with the AGP module not correctly detecting the card in the first place

Edit: also tested it with the internal screen connected, still the same problem.

Yeah, sorry I'm out of ideas for going forward. I had hoped that the display was causing the issue but you state that the kernel can't even see it. Hopefully someone else will be able to chime in.

Ok, I got myself a new laptop so this problem is not relevant to me anymore

That's one expensive solution, I must say

As I wrote in the first post, the problem occurred with an old temporary system that I used because my laptop's motherboard died, so I had to buy a new laptop anyway, I just hoped I could have decent graphics on my temporary system while I had to use it.
But thanks to everyone for helping and happy holidays
