  1. Dual head Matrox issues


    Hello all,

    I have a couple of odd issues with KDE 3.4 on Suse 9.3

    I have a dual head set up with 2 flat panels and a Matrox
    G200 dual head card. Both displays are set up at
    1280x1024x24. All works well except for a couple of
    odd issues.

    I have the left display set up as the primary. When you
    hover the mouse over a panel icon, you get a real nice
    information tooltip display with rounded corners and
    information about the icon and a bigger pic of the icon.

    However, on the right display panel, you dont get this.
    All you get is the old style tooltip that does not show
    the Icon, just what app the Icon runs. No rounded
    corners and it is also very small. This is the way it was
    in KDE 3.1 I believe.

    The other odd, but perhaps normal issue is not being
    able to drag apps from one display to the other. Basically,
    you need to start the app in the display you want it in. The
    mouse will span both displays, but you can not drag the app
    from display to display. This may be the way I have X set up.
    I am using duplicate driver and card sections in my X config
    file. Perhaps I need to try one driver and display section,
    but with a resolution of 2560x2048 ??

    Any and all suggestions are welcome and appreciated.

    Each "display" has it own settings, you need to run the panel configuration in
    the secondary display and set it to use the new type of tooltips instead of
    the classic.

    Well, I have already tried that. I could find nothing
    "different" between the 2. I checked settings till I
    was blue in the face, comparing each and every one
    the best I could. I was not able to run 2 configs at
    the same time, that would have made it much easier.

    Now, I could have simply missed where this is set,
    can you tell me exactly where to set the "ToolTip"
    style or whatever it may be called ?

    Oh, and thanks for the very fast response.

    Any ideas on dragging apps between displays ?
    Is that just what I am going to have to live with
    which I can easily do.

    That would be the preview (not the thumbnail preview). It is sometimes
    rendered a little inconsistently, at least in older versions of KDE. It is
    very valuable nevertheless.

    CORRECTION to above: I was thinking about something else, namely the large
    yellow balloon. Ignore my comment.

    While I'm at it, in KDE 3.1 I noticed some troublesome (yet extremely rare)
    bug where the tooltip balloons show up with the right coordinates _at the
    wrong screen_. I suggest that you file a bug report if you still see this.
    Also in KDE 3.1, having fancy cursors on screen 2 causes X to crash
    immediately. I reported this as a bug years ago, so it has probably been
    resolved.

    In KDE 3.1, which I use at this very moment (3.4 remains at home), there were
    no fancy balloons. There exist some standard balloons (yellow title with
    application name or path) and there is icon zooming in the panel, which can
    be dis/enabled in Control Center.

    How have you defined your monitors? Maybe they are badly configured. Have you
    let SaX2 (in YaSY/Control Center) handle this? You can see my own X
    configuration file, where the more crucial bits are at the end:

    http://schestowitz.com/Data/XF86Config

    Also see the resource that Mr. Aho pointed you to. This can be rather
    helpful.

    Hope it helps,

    Roy,

    Yes, the small yellow tooltips you describe are what I am
    getting on the right monitor.

    As for my X config, I had to edit the file manually. Sax2
    never ever saw the second monitor, or the ability of the
    card to support 2 monitors. Every time I would select
    the Dual Head setup, it would whine about not having
    a second monitor to support dual head. That was a while
    ago I did this so I dont remember the exact details. I
    just remember that I had to edit manually.

    I did a bit of googlin, and at the time I was Suse 9.2.
    I found an article in google stating there was no dual
    head support in Linux for the G200. That is when I
    started hacking at the X config file and got it to work.
    So, obviously that article was incorrect.

    If Sax2 would do the job, I would have used it. I just
    could not get it to recognize the dual head ability.

    I will visit the reference mentioned earlier, thanks.

    Roy,

    Just looked at your X config file. Looks set up just like mine is.
    Can you drag Apps from one display to another ? I can not, and
    that would be nice to get working if it is possible.

    Right click over a panel in your main desktop (and then redo this for your
    secondary) and select from the menu "Configure Panel...", at this point you
    will get a new window open, here you select "Appearance" among the icons on
    the left side of the window. You will see a "General" area ontop of the window
    where you have two options, "Enable icon mouseover effects" and "Show
    tooltips", both has to be enabled and you get the new type of tooltips.

    If you still don't get the tooltips to work properly on boths displays, this
    may be caused by a bug in the version of KDE you are using (tooltips code is
    buggy and has quite random events, I do get tooltips even if I have disabled
    them). See kde.org for bugs.

    As I said, you need xinerama enabled to be able to do this, this will also
    lead to your desktop will be the total of the two, eg you have two 1200x1024
    displays placed side by side, then you "new one" will be 1200x2048. Or if you
    put the ontop each other, 2400x1024.

    There are quite many documentations and HOWTOs around on the net, you need to
    keep an eye on for which program and _version_, in older X, there was no
    support for the secondary output in the matrox driver, but for each new
    version of X (Xfree86/Xorg/XiG/...) the drivers gets better and better and
    supports more and more features. It's like if you would read the manual for
    T-ford and tried to maintained your Ferrari, maybe some things are okey to use
    from the manual while other parts aren't usable at all.

    Sorry, I somehow missed missed this, my apology. I will mess with
    Xinerama and see where it gets me. I did have a quick look at the
    link and they mention many times that the articles are for 2 seperate
    cards, I only have one card with dual output. But you never know.

    Thanks again.

    There is no difference in having one card with two outputs and having two
    cards with one output each, in the days when the HOWTO was written, graphics
    cards had only one output (of course there always exceptions, but those cost a
    good bit over US$1000).

    Yes, it works just fine in SuSE 8.1 with KDE 3.1. The behaviour of any item
    is irrespective of the monitor in which it is contained. Even window
    placement takes account of both monitors (options for this in Control
    Center), so it's as though a wide display exists and it is transparent to
    the hardware used.

    Best wishes,

    Roy

    In case you care, your advice on "Configure Panel" did work. I feel
    pretty darn stupid that I did not try that, but that is what the NG's
    are for I guess, to make you feel stupid.

    Thanks a million.

    I will now pursue the Xinerama advice you gave.
