[i855GM] entire display shows just one color unless LVDS disabled

Thank you for reporting this bug. That was certainly an interesting behaviour. Could you attach the output of `lspci -vvnn` as well? Does anything change if you move /etc/X11/xorg.conf to a different name and restart? (so that there is no xorg.conf when you start up, there will be a new minimal one created.)

Also, what is your monitor setup? Is this a laptop? Is there an external monitor connected using DVI? If this is not a laptop, you can try the Ignore LVDS Quirk on https://wiki.ubuntu.com/X/Quirks#Ignore%20LVDS%20Output%20Quirk .

i tried the quirk and now i see a proper image, but first to my system setup.

the system is a not a notebook but not a common desktop either. mainboard is a mb890 (link http://www.ibase-i.com.tw/mb890.htm ). the mainboard has three video outputs: VGA, DVI and LVDS. my monitor is connected to the DVI output. monitor is an IBM ThinkVision L200p. other video outputs are not connected to anything, as far as i can tell.

my xorg.conf was already a "minimal" xorg.conf (as created by dpkg-reconfigure), so renaming xorg.conf and restarting x didn't change the behaviour. i then tried the quirk and added the LVDS ignore lines in xorg.conf and now i have a proper image, but the resolution is limited to 1024x768. the monitor is able to go up to 1600x1200.

should i post a new "Need LVDSout quirk for <your video card PCI ID>" bug as suggested in the wiki? i do see a proper image now but the resolution is still not correct. i'm sure it would be possible to force xorg to 1600x1200 using appropriate xorg.conf lines, but it would be better if the driver did it right automatically.

If the LVDS quirk that can be added to the driver works as I think it does (basically by doing the same as adding the stuff to xorg.conf, but by default), it may be problematic to add it, since one may also want to connect that main board to a LVDS output and that wouldn't work if the driver quirks it away. But I'm not an expert, so we can let the experts decide.

What about changing the name of this bug to "Need LVDSout quirk for 8086:3582" and opening a new one (referencing this) for the resolution issue? (most of the information in this report is about the LDVSout problems anyway.)

changed the bug title

i think this bug covers my other problem:

From feedback on the upstream bug, this quirk causes issues for other hardware using this same chipset.
So we may need to revert it and ask you to just use the xorg.conf option to control the LVDS enablement.
I'll just leave this bug open for a bit before making that change, in case a better idea comes along.

Lesmana, please test the newer 2.6.99.1 git snapshot of the -intel driver to see if it contains the fix already:
http://ppa.launchpad.net/xorg-edgers/ubuntu/pool/main/x/xserver-xorg-video-intel/

i tried the 2.6.99.1 driver using the ubuntu 9.04 alpha 4 live cd. i was not able to install the 2.6.99.1 driver under ubuntu 8.10 because of the dependencies.

to be exact, i used following command: dpkg -i xserver-xorg-video-intel_2.6.99.1+git20090207.3aa8591a-0ubuntu0tormod2_i386.deb

the 2.6.1 driver shipped with the alpha 4 live cd was working fine (although still with the 1024x768 problem). the 2.6.99 driver showed the same problem as in my original report, the entire display showed the color of one pixel. perhaps this is because of the integrated LVDS quirk in the 2.6.1 driver?

[Setting to incomplete pending testing of newer driver]

Yes, the 2.6.1 driver worked because of the lvds quirk we're carrying for this bug. (I will be dropping it once we have a proper fix.)

If I understand your prior comment, xserver-xorg-video-intel_2.6.99.1+git20090207.3aa8591a-0ubuntu0tormod2_i386.deb did *not* resolve the issue.

I'll comment on the upstream bug; please subscribe to the upstream bug and put your comments there, so progress on solving this bug isn't bottlenecking on me (I'm pretty swamped with other stuff so may not be able to stay on top of this bug.)

Lesmana, upstream needs some further information from you, so please subscribe to that bug and provide it to the upstream report.

Thanks for testing this upstream, I will pull it into Karmic.
