"Displays" is registering dual monitors as "laptop" when using fglrx

Status changed to 'Confirmed' because the bug affects multiple users.

Same problem, same Ubuntu versione, same drivers (fglrx), my graphic card is an ati mobility radeon hd 5600

Here is my "Displays" Window, as you can see all the monitors are named as "Portatile" wich in Italian means "laptop", but just one of the two monitors is the laptop one.

Also in "Color" capplet I can see all the monitors listed with the same name

Thank you for your bug report, could you add your /var/log/Xorg.0.log to the bug?

Here is my Xorg.1.log, cause today I've not connected the second monitor

Status changed to 'Confirmed' because the bug affects multiple users.

Ok, I think it's due to this change:
http://git.gnome.org/browse/gnome-desktop/commit/?id=ead1b3478c86e80237c79c6f618d8187b6cd9eeb

Your log has "[ 1478.551] (II) fglrx(0): Connected Display1: DFP2"

or DFP displays have been added as laptop screens to workaround macbook,binary driver bugs preventing proper screen detection, not sure there is a lot we can do about that, better to have the naming wrong than to breaks suspend...

Can we add some code to make some distinction between macbooks and other laptops in order to apply the patch you linked only in case ubuntu is running on a macbook?

It's very noising and confusing to see the tv connected to the computer through hdmi cable as a laptop monitor.

we could probably be smarter about it but it requires guess work and the issue is mostly cosmetic since you can look at the rectangles drawing to see which one is which so it's not an high importance issue compared to other bugs

I know that this is not a critical bug, but IMHO we cannot consider it just
as a cosmetic problem. In fact people usually doesn't look at the rectangle
color you mentioned, but they focus on the label they see in "Display"
window, and they get confused.

I'm not a professional developer, i saw in the link to the change you
posted above, that the bug may be caused from a condition added in an "if"
expression:

strstr (output->name, "DFP")

Couldn't we modify the code in order to apply that condition ONLY if the pc
is a mac?? For example:
from: strstr (output->name, "DFP") to something like this: (strstr
(output->name, "DFP") && some_variable_that_make_me_know_it's_a_mac)

I know that it's an ugly solution, but now, in this moment, the application
isn't working properly, with that ugly workaround (that maybe we will
remove once the problem is solved in a better way) the application works.

Maybe i'm just writing a lot of rubbish, but in this case, i'd like to know
the reason.

In this period I made some test and I also noticed that the color of the
rectangles you wrote about are wrong, in fact in the monitor that "Display"
window marks with the red color I can see a rectangle with a green one, and
the same is for the other... It's not so intuitive that in order to modify
the resolution of the monitor with the red rectangle i have to modify the
resolution of the monitor marked with the green color in "Display" window.
Maybe if you need in these days i'll post some screenshots.

I hope we will find a solution in order to make Ubuntu a better Distro.

I am having the same problem using a Integrated NVidia GF8100 Graphics with DX10. I totally disagree that this is minor problem.
The video card has to be detected properly in order for the Gnome Color Management to function properly to get the correct ICC profiles imported for whatever hardware needs to be configured. Because we are now using ICC profiles in lieu of the old manual configuration methods. My system is only detecting my motherboard an my printer. My monitor is not being detected, hence my colors are all screwed up. If any one can tell me how to correct this problem I will be eternally grateful. I have searched the internet for days with no success.

Thank you for taking the time to report this bug and helping to make Ubuntu better. The issue you are reporting is an upstream one and it would be nice if somebody having it could send the bug to the developers of the software by following the instructions at https://wiki.ubuntu.com/Bugs/Upstream/GNOME. If you have done so, please tell us the number of the upstream bug (or the link), so we can add a bugwatch that will inform us about its status. Thanks in advance.

Here is the link to the bug in bugzilla.gnome.org: https://bugzilla.gnome.org/show_bug.cgi?id=679858 I posted with details, links, and screenshots taken from this bug

It seems GNOME guys reverted the change Sebastien posted here, so the bug is "fixed". Any chance to see this bug closed in Ubuntu 12.04 too?

The issue was fixed with 3.5.4 in quantal

Thank you very much Sebastien. Can we hope to see this fix applied in an
LTS release like 12.04 too?

Hello Britt, or anyone else affected,

Accepted gnome-desktop3 into precise-proposed. The package will build now and be available at http://launchpad.net/ubuntu/+source/gnome-desktop3/3.4.2-0ubuntu0.1 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please change the bug tag from verification-needed to verification-done. If it does not, change the tag to verification-failed. In either case, details of your testing will help us make a better decision.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance!

Perfect!! I'll try this evening or this Sunday

I don't know how to change tag, but with this new version, my monitor and projector are recognised by their names, so I can confirm that this solves the problem with "Laptop" names.

I can confirm the fix works for me too!

The verification of this Stable Release Update has completed successfully and the package has now been released to -updates. Subsequently, the Ubuntu Stable Release Updates Team is being unsubscribed and will not receive messages about this bug report. In the event that you encounter a regression using the package from -updates please report a new bug using ubuntu-bug and tag the bug report regression-update so we can easily find any regresssions.

This bug was fixed in the package gnome-desktop3 - 3.4.2-0ubuntu0.1

---------------
gnome-desktop3 (3.4.2-0ubuntu0.1) precise-proposed; urgency=low

  * New upstream version
  * debian/patches/git_dfp_is_not_laptop_screen.patch:
    - don't classify DFP output as laptop screen, that's often a wrong
      categorization (lp: #970560)

I haven't noticed this before. I'm using nVidia drivers, and the display utility reports the screen as a laptop for me as well, before and after the gnome-desktop3 (3.4.2-0ubuntu0.1) update.

I've attached a screenshot and here's a link to the LED monitor I'm using: http://www.viewsonic.com.au/products/lcd/VX2753mh-LED.php

Having the same reports that my display is a laptop @800x600 when in fact it is lcd hp 2009m

one user way of going around this problem is to use the NVIDIA X Server Settings - in here it is possible to see the other screen as disabled, here you can enable again :-)

This also affects me.

@khamisi
I do not have this problem anymore, so, there is something strange. What version of Ubuntu are you using?

Im running 12.04. But i am using a radeon hd graphics card..i unistalled
the fglrx driver and reinstalled it- at that point my display did in fact
show the correct monitor
