Description joern 2011-10-11 13:31:57 UTC

Description of problem:

I have a Dell Latitude D830 with 1680x1050 display, and an external
1920x1080 monitor above.  With Fedora 15, the only Desktop that lets
me configure this properly is KDE.  Before I got the external monitor,
I've been using LDXE, but in Fedora15 that will always place the monitors
logically side-by-side, with no user controls to change this.  So I decided
to give the Fedora16 Beta a try.

Version-Release number of selected component (if applicable):

Whatever is on the Live CD Beta spin.  Without a main menu I can't really
look at much.

How reproducible:


Steps to Reproduce:
1. Use dd to copy Fedora-16-Beta-i686-Live-LDXE.iso to USB stick
2. reboot and select boot from USB
3. Boot into live image
  
Actual results:

Desktop has built-in display logically left of external display.
There is a panel on the bottom of the external display, but it does not
have a main menu.

Expected results:
A main menu available somewhere so that the desktop can be rearranged
to something useful, and applications (e.g. xterm, firefox) can be started.

Sorry it took so long. 

AFAICS this is not a new problem, there should be no difference between F15 and F16. Is there for you?

LXDE has a very poor multiscreen support. This affects both lxpanel and pcmanfm. for pcmanfm work is going on atm but I not aware of any efforts for lxpanel.

Comment 2 joern 2011-11-11 02:00:27 UTC

I can't remember what it was, but LXDE in F15 also didn't work with multi-monitor
support.  I find that the only practically available desktop environment in F15
with multi-screen support is openbox (LXDE and XFCE have configuration problems,
KDE4 is so slow that it is non-interactive, Gnome 2 is missing.)

Comment 3 Christoph Wickert 2011-11-11 13:41:26 UTC

Well, openbox doesn't really support multiscreen either, LXDE uses openbox. But Openbox doesn't have a panel, so the problems are not obvious.

Nevertheless this is more a feature request than a bug report and is better discussed upstream with a wider audience. I filed https://sourceforge.net/tracker/?func=detail&aid=3436539&group_id=180858&atid=894872 and this is where future discussion should take place.

Comment 4 joern 2011-11-11 14:27:44 UTC

Well, openbox does have a main menue that is accessible by right-clicking
on the desktop, and it has a preferences->displays point that works
sufficiently (desired setting isn't available immediately, but is reachable
after setting both screens to a common resolution) that I can configure
the displays to their full resolution and in the desired spatial relation
to each other.  Well, at least that's the case in F15.

AFAICT LXDE takes away this configurability via right-click menue, and the
menue on the display is the supposed replacement - but it just doesn't have
the functionality of the original openbox configuration.

Whatever program this is: It's not part of openbox. I guess it's either gnome-display-properties or it's kde counterpart.

You can turn of pcmanfm's menus and use the openbox one in the desktop properties.
