[Bug 13214] Blank internal Display on Notebook with Intel GPU (855GM)
http://bugzilla.kernel.org/show_bug.cgi?id=13214
--- Comment #10 from Bruno bonbon...@internet.lu 2009-05-17 09:46:14 ---
Regarding Stefan's suggestion in comment #5, that does not seem to help on my
side.
I did try a slightly different approach (e.g. not forcing ALL outputs to get
handled as LVDS), but internal display kept showing black content.
When booting with a VGA display connected (1280x1024 native) I do see kernel
boot output on external monitor (though that one is complaining about signal
timing: horizontal 40.0kHz, vertical 37.5Hz)
(Note: while playing with Xorg (1.5.3 + 2.7.1 driver) I could not convince the
local display to change it's mind but had both displays unexpectedly disabled
at some time andsystem frozen hard slightly later)
The patch I used looks like this (sorry for line-wrapping):

Will try with unchanged refclk to see if this one does affect signal timing.

(the injected 1400x1050 is just wrong for the external display - but this probably should go to a separate bug report - this is an Xorg/fx86-video-intel issue as the extra mode is not listed by kernel) ps: tests for this and previous comment were done with 2.6.30-rc6 -- Configure bugmail: http://bugzilla.kernel.org/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are watching the assignee of the bug. -- Crystal Reports - New Free Runtime and 30 Day Trial Check out the new simplified licensing option that enables unlimited royalty-free distribution of the report engine for externally facing server and web deployment. http://p.sf.net/sfu/businessobjects -- ___ Dri-devel mailing list Dri-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/dri-devel

Hi,
I played it little with the KMS-kernel-code and got the internal display
running. I disabled some lines in the file intel_display.c to force-enable
the LVDS-output :
switch (intel_output-type) {
/*case INTEL_OUTPUT_LVDS:*/
is_lvds = true;
/*break;
case INTEL_OUTPUT_SDVO:
case INTEL_OUTPUT_HDMI:
is_sdvo = true;
if (intel_output-needs_tv_clock)
is_tv = true;
break;
case INTEL_OUTPUT_DVO:
is_dvo = true;
break;
case INTEL_OUTPUT_TVOUT:
is_tv = true;
break;
case INTEL_OUTPUT_ANALOG:
is_crt = false;
break;*/
}
num_outputs++;
I know, it is a very crude hack, but i know to little about the
drm-kernel-stuff to make a better solution. I hope some kernel-hacker can
improve the code, so i can normally use KMS.
P.S. :
I also had to add the following patch to the same file to improve the image
quality. Without this patch my LC-Display constantly flickers.
} else if (IS_I9XX(dev) || IS_I855(dev)) { /* Added query 855GM-chipset
refclk = 96000;
} else {
refclk = 48000;
}
