Need to add a quirk to xserver-xorg-video-intel

Need to add a quirk to xserver-xorg-video-intel

[Gabriel M. Beddingfield]

Hello,

I'm needing to add a quirk to xf86-video-intel.  It looks 
like I can get the first two columns from lspci 
(chipType, subsysVendor == [VEND:CHIP])...

But I can't figure out how to get the number for subsysCard. 
(But I gather that I need to interpret `dmidecode` for this 
part.)

Thanks in advance!

Duh, I overlooked the answer here:

    $ lspci -vvnn | grep -A1 "VGA compat"
    00:02.0 VGA compatible controller [0300]: Intel Corporation Mobile
4 Series Chipset Integrated Graphics Controller [8086:2a42] (rev 07)
           Subsystem: Micro-Star International Co., Ltd. Device [1462:1021]

So, looks like my row will be:

    {PCI_CHIP_GM45_GM, 0x1462, 0x1021, quirk_ignore_tv}

Thanks,
Gabriel

I have to ask: why do you need a quirk in the userspace code? Mode
setting and output detection is now done in the kernel and it may just be
that the TV detection code is inadequate for your setup. Please do file a
bug with the details of the problem and the workaround you have found.

I'm forced to use some older stuff:

     2.6.31 kernel
     2.9.1 xf86-video-intel

The newer KMS drivers break some things on my old system.

Meanwhile, I have a couple of machines that will always 
report "Output TV connected" when doing a soft reboot -- 
whether there's a cable connected or not.  This messes up 
the desktop resolution.

Let me know if you have a better solution.
