Description shiBB 2010-04-10 19:31:21 UTC 
Version:            (using KDE 4.3.5)
OS:                Linux
Installed from:    openSUSE RPMs

I got a Notebook and want to plug in an external monitor. Clonemode works perfectly as well as an extended monitor setup. The only problem with extended monitor is, that the main screen switches to the external screen so all the plasmoids, desktopbackground, panel etc is on the external screen and there is no way of changing that.

I was wondering about that, because the external monitor is detected as the secondary screen and kdm shows up the loginscreen on my notebook's screen correctly.

hardware:
dell studio 1555 notebook
gpu: ati mobility radeon hd 4570
driver: fglrx 8.712-1 (latest)
arch: x86_64

Exactly same issue with KDE 4.4 on Kubuntu 10.04. My secondary screen is pivoted and have lower resolution than my laptop screen. It's perfect for web browsing but not for plasma applets and taskbar.
Comment 2 Oldřich Jedlička 2010-05-06 07:26:16 UTC 
It looks I have the same problem, but reversed.

When I go to Display Settings/Multiple Monitors and click Identify All Displays, it always shows "1" on my notebook's LVDS and "2" on LCD (when attached).

Now my problem: I'm running priparily with LCD attached, so my panel is configured on display "1" (=notebook's LVDS). When I go out and take only notebook with me, the panel isn't visible at all after start-up, but it is up and running according to running plasmoids (but completely unreachable). So I have to configure new panel for notebook's LVDS (on display "1"). But then (this is what is described in this bug report I think), when I return back and boot with LCD attached, I see two panels - the LVDS has the original one, LCD has the newly configured one.

Please note that my KDM start-up scripts contain automatic xrandr configuration of the LCD screen to be "right-of" LVDS - the KDE starts into prepared multi-monitor set-up.

"the main screen switches to the external screen so all the
plasmoids, desktopbackground, panel etc is on the external screen and there is
no way of changing that."

because x.org changes the #'ing of the screens and the elements are attached to screen #. it would make a lot more sense if x.org didn't do this if the primary screen isn't changing.

as there is absolutely no concept in plasma of a "primary screen layout" it listens to the screen numbering.

"When I go out and take only
notebook with me, the panel isn't visible at all after start-up, but it is up
and running according to running plasmoids "

this is fixed in 4.5

I don't understand this. Whenever I select Display/Multiple Monitors/Identify All Displays, I always see "1" on my LVDS - with and without the DVI-D connected. This doesn't change.

How can I check that the numbering has changed?
