One screen only with Matrox G450 dual head

[destroyedlolo]

Binary package hint: xserver-xorg-video-mga

Hi all,

I own a dual head graphic card but nothing is displayed on the 2nd monitor.

The "Display" preference detects only one screen which is display as "Unknown". And when I click on "Detect display" nothing happen.

Best regards,

Laurent

Me too, with a later Matrox card, reported as;

01:00.0 VGA compatible controller: Matrox Graphics, Inc. Millenium P650/P750 (rev 02)

I assume that this driver package is appropriate for that card as well.

[destroyedlolo (destroyedlolo)]

I think the problem is with the driver of this card which is very poorly supported : as example, Ubuntu is unable to detect the monitor attached to this device (always displayed as unknown) whereas the same one is perfectly detected on another machine as per Question #93091.

Best regards,

Laurent

I have exactly the same problem with the G450 card in my work machine. Since the bug is marked as confirmed i'm not sure how much info you need...please let me know if you need anything from my system.

[eval- (eval-)]

I have dual-out on Lucid, but xrandr only shows one screen and detect monitors shows "Unknown." However, it did guess to the appropriate LCD resolution 1280x1024. All my gnome-panels are incorrectly sized or do not appear at all until I play with the monitor size, making bigger or smaller. No idea if that's a Lucid Beta2 gnome-session bug or again related to this sad mga driver...

[eval- (eval-)]

... by dual-out I mean the same display, duplicated. not two independent desktops =( ...

packages in https://bugs.edge.launchpad.net/ubuntu/+source/xserver-xorg-video-mga/+bug/292214 plus some re-hacking of my xorg.conf fixed my problem. Thanks!

Hi destroyedlolo,

This bug was reported against an earlier version of Ubuntu, can you
test if it still occurs on Lucid?

Please note we also provide technical support for older versions of
Ubuntu, but not in the bug tracker. Instead, to raise the issue through
normal support channels, please see:

    http://www.ubuntu.com/support

If you are the original reporter and can still reproduce the issue on
Lucid, please run the following command to refresh the report:

  apport-collect 479624

If you are not the original reporter, please file a new bug report, so
we can work with you as the original reporter instead (you can reference
bug 479624 in your report if you think it may be related):

  ubuntu-bug xorg

If by chance you can no longer reproduce the issue on Lucid or if you
feel it is no longer relevant, please mark the bug report 'Fix Released'
or 'Invalid' as appropriate, at the following URL:

It still occurs in lucid.

compiling 1.9.100 is not an option anymore as it does not compile against lucid's Xorg

[Ryan Long (me2000r)]

I can also confirm that it occurs in Lucid, at least in an upgraded-to-Lucid system. My original install on this system was 8.04, I believe. I will test on a fresh install soon and report back.

What information can I provide that is helpful?

[John (john-robson)]

Only detect one one screen in Lucid - hence cloned displays.

The displays are fine though:

xrandr only detects screen 0

Above ppas etc. appear to require xorg-server which I can't find in Lucid.

Anything else useful I can provide?
