Dock not correctly drawn on multi screen using cairo backend

[Francois Jaouen]

The background of the dock is not correctly drawn on the right side, as you can see on the picture.

The configuration is :
- 2 monitors
- cairo position is way shifted on the left (the origin of the error IMHO). Posistion is : Décalage latéral = -642

Filling this bug, I've just discovered the xinerama option in Position option using it and resetting Décalage latéral to 0 (the default), everything works perfectly.

Anyway, I believe there is a little bug with the dock background when changing lateral shift a lot, so I keep this bug report opened

More details :
- ubuntu 9.10 x64
- cairo : 2.1.3.7
- Nvidia driver : 185.18.36
- screen 0 : 1680x1050
- screen 1 : 1280x1024
- cairo-dock mode : pb either with glx or not

Hello François,

Can you try two things :
* First, can you enable the Xinerama option (Advanced mode / Position). Maybe reset the 'Décalage latéral'
* If it doesn't work, can you try our weekly ppa ? => http://www.glx-dock.org/ww_page.php?p=ppa%20Weekly&lang=fr

Thanks

Hello Matthieu,

Thanks to be so reactive.

I've tried what you've ask :

- Xinerama mode, 'Décalage latéral' set to 0 (default)
Although yesterday I said that it corrects the problem in fact it doesn't

- weekly ppa
Same result, the problem is still there.

Nevertheless, I can give you another clue :

Whatever is the configuration (xinerama, weekly ppa), if I launch CD
after I'm logged in (gnome desktop displayed) the problem doesn't
appear, but if I launch CD during gnome session startup then, whetever
the configuration is, the problem appears.

To launch CD at startup I have added in 'Système > Préférences >
Application au Démarrage' an entry for CD with the command :
/usr/bin/cairo-dock -c

Thanks

Hello Matthieu,

I'd like to more accurate than Sunday ! Forget about startup/non startup launches, the problem is elsewhere.

If cairo-dock is launched with -o (opengl), then it is displayed correctly (at least with the beta version currently available with your weekly ppa)
If cairo-dock is launched with -c (cairo) then the problem appears, be it launched at session startup or afterward.

So definitively it is a bug in cairo backend only.

[Matthieu Baerts (matttbe)]

Thank you, François !
I hope it will be fixed soon but 'soon' is maybe "not before two weeks" ;)

PS: don't hesitate to report any bugs with multi-screens because nobody here has two plugged screens continuously !

[Matthieu Baerts (matttbe)]

Hello

Do you still have the bug with the latest 'weekly release' ?

[Alienation (miguel-andrade)]

Bug is still here for me with version

2.1.4-0beta0-20100417

[Alienation (miguel-andrade)]

Just tested again and the behavior is different. All subdocs are now drawn in the rightmost position of my screen 0. (with xinerama) same with opengl or not.

[Fabounet (fabounet03)]

ok, I'm trying to fix it but without a dual-screen it's quite hard ^^
what if you set the dock on the screen n°1 ?

if I set in screen 1 its all ok, but the doc gets to low because screens have different resolutions.

Im attaching a complete screenshot. Leftscreen (1) is maximized. Doc is on screen 0 (right) and I have hover the weather plugin. Note the whether forecast to the rightmost.

Thanks

[Fabounet (fabounet03)]

well thanks a lot for your screenshot.
I might have fixed the problem this time :-)

Just some feedback:

With the last updates Xinerama seams to be not working (if I choose screen 0 the dock disappears ) and the best configuration I can do you can see in the attached screenshot where you can see the weather subdock at the middle of both screens.

[Francois Jaouen (francois-jaouen)]

Some feedback

Using the latest weekly version, the dock works perfectly for me either with xinerama mode or with position shifted to the left.

[Matthieu Baerts (matttbe)]

I don't know why but I can't copy the new weekly version on the weekly ppa:
      Oops!
      Sorry, something just went wrong in Launchpad.

      We’ve recorded what happened, and we’ll fix it as soon as possible. Apologies for the inconvenience.

      (Error ID: OOPS-1587ED972)

But if you want, you can manually download deb packages there: https://launchpad.net/~matttbe/+archive/experimental/+packages
(PS: please, do NOT add my "experimental" ppa to your sources.list !)

[Fabounet (fabounet03)]

well I think we can close this one, finally ! :-)
I'll wait one more positive return.
