Need LVDSout quirk for 8086:2592 a0a0:0589

[Tormod Volden]

Binary package hint: xserver-xorg-video-intel

This is a mini-pc with DVI-I and S-video outputs: http://global.aopen.com/products_detail.aspx?auno=2164

$ lspci -vvnn | grep -A1 "VGA compa"
00:02.0 VGA compatible controller [0300]: Intel Corporation Mobile 915GM/GMS/910GML Express Graphics Controller [8086:2592] (rev 04) (prog-if 00 [VGA controller])
 Subsystem: AOPEN Inc. Unknown device [a0a0:0589]

Using Hardy, it's difficult to change resolution to anything else than 800x600, even if you choose 1024x768 in gnome-display-properties. Disabling (ignore) the non-existing LVDS output like described in https://wiki.ubuntu.com/X/Quirks#Ignore%20LVDS%20Output%20Quirk works well.

For the record, there are other things not quite right, but I'll file new bugs as I find out more about it. That the connected VGA flatscreen seems to return wrong information doesn't help. But also the TMDS-1 output which is disconnected (I am using a DVI-I to VGA adapter) seems to be detected by the driver - maybe the load detection is broken. Finally, I have the impression gnome-display-properties mix up the output, the screen labeled "Hansol" (name of the VGA monitor) controls the non-existing output and the "Unknown" controls the VGA output to some degree.

The issues in my last comment seems to be that output and EDID info is associated to the wrong output, and I reported it upstream in http://bugs.freedesktop.org/show_bug.cgi?id=18004

[Tormod Volden (tormodvolden)]

For the record, I have now verified with another computer (and driver) that this monitor's EDID information is fine. So the problem is really the outputs being mixed up on the mini-pc.

I will deal with the other issues in bug #278032, so this bug can stay focused on the missing LVDSout quirk.

Hi tormodvolden,

Thanks for including the attached files. Could you also include your /var/log/Xorg.0.log?

[Tormod Volden (tormodvolden)]

Hi brycerobot :)
It's already attached in comment #1.

Looks like a fairly broad set of quirks are already upstream, we should just make sure these get into Jaunty with the next upload, and perhaps consider backporting them as well.

    { PCI_CHIP_I965_GM, 0x8086, 0x1999, quirk_ignore_lvds },

These are included in the 2.6.1 driver now in Jaunty.
