Version: (using Devel) Installed from: Compiled sources I've just tried to use xrandr to activate my second head (using xrandr --output VGA-0 --mode 1680x1050_85.00 --right-of LVDS) and it worked (albeit kwin crashing and restarting itself, not a big deal). However plasma didn't create a containment for the new second head and thus there's simply no plasma support for that head now (i.e. no wallpaper, no toolbox). This works just fine if the head is already configured when plasma starts (i.e. I setup the second head in my X11 configuration). Looks like either plasma doesn't get notified about the head addition (IIRC I found with Aaron some problems in QDesktopWidget which didn't know about xrandr 1.2 or didn't use the X11 notification API from that properly) or it doesn't do the right thing when it gets the notification about the new head.
can you try with recent trunk/, and if it is still broken send the output to console of plasma when you activate the second screen? thanks =)

That was a pretty recent trunk/ version (from sometime last week). But luckily I've just rebuilt last night so I'll retry when I'm back home.
Hmm, tried to do startkde 2>&1 | tee kde.out but I don't see much "plasma" in there. The only lines I get are: andreas@morpheus:~>grep -i plasma kde.out kdeinit4: Got EXEC_NEW '/home/andreas/kde4/bin/plasma' from launcher. kdeinit4: preparing to launch /home/andreas/kde4/bin/plasma <unknown program name>(21416)/ checkComposite: Plasma has an argb visual 0x805b698 29360129 <unknown program name>(21416)/ checkComposite: Plasma is COMPOSITE-less on 0x8054b28 QLayout: Attempting to add QLayout "" to Plasma::Dialog "", which already has a layout plasma(21417)/kdeui (KIconLoader) KIconLoader::loadIcon: No such icon "system" plasma(21417)/kdeui (KIconLoader) KIconLoader::loadIcon: No such icon "kfm_home" plasma(21417)/kdeui (KIconLoader) KIconLoader::loadIcon: No such icon "trashcan_full" plasma(21417): Failed to lock file "/var/tmp/kdecache-andreas/kpc/kde-icon-cache.lock" , last result = 1 I guess thats not very helpful. Any hint how to get more information out of plasma?
hmm... you should be getting some lines that start with "Containment name:". after you've logged in, open a konsole, kquitapp plasma, plasma and send the entire set of output that appears if you could. thanks in advance =)

no, but the missing debug out is. i really wonder what's happening to the debug output from plasma the application itself. until you can get that debug showing, there's nothing more i can really do from this side. please ensure that plasma is built with debub and that the debug area for (1209) it hasn't been turned off

Aaron, in case you didn't see my answer last night during half-time of the football game. The above output include the point where I literally plug in the monitor cable. Doing this again and looking at plasma's debug output indicates that plasma doesn't "do" anything when this happens, i.e. there's no output produced when I plug in the cable.
*** Bug 174059 has been marked as a duplicate of this bug. ***
Just setup a xorg.conf for the 2 monitor with large desktop case and this problem is almost gone with that. I still kinda have 2 containments on the first head (i.e. see 2 different parts of the background wallpaper clutched together in the middle of the screen and a dashboard widget that also sits around the top-middle.
*** Bug 179601 has been marked as a duplicate of this bug. ***
I think the "static xorg.conf setup" case works now, but the dynamic adding of a monitor still is the same: - I do get a desktop wallpaper on initial adding, but its kinda broken (see 179601) - No context menu on the desktop - no cashew, but now I see a second cashew on the first screen. Its at the same position than the one for the first screen, but a slight bit off. Looks like the view through binoculars that are not setup properly for your own eye-distance, or as if I'm squinting while looking at them. So I can actually highlight both and I also get the normal menu from both via right-click. But the settings dialog has the same content no matter which of the two cashew's I use. Oh and one is apparently behind the other, thanks to transparency thats easily visible when mousing over the lower one. - bright gray background, after moving a window a bit into the second screen and out again.
Interesting, there's absolutely 0 output from plasma when adding a screen via xrandr. The kephal library itself unfortunately uses qDebug, so I only have that in .xsession-errors, along with a lot of other stuff. If you want to I can post it here, but it might be easier to first replace qDebug() in kephal with proper kDebug and an apropriate debug area in kdelibs and then re-run the experiment.
what i need to be able to make progress is: * output from kephal at the moment xrandr picks up the second screen * output from plasma over the same time period * the svn rev# you are using
oh, btw, you can also run kephald directly for testing as a stand-alone daemon seperate from the kded one. =)
svn is "from yesterday", something around 10pm my time (GMT+1), I'll do an update+build before the next test. plasma didn't print anything at the time I plugged in the monitor via xrandr, but thanks for the hint about kephald, that should help getting the wanted output without posting huge files :)
svn rev kdelibs: 907816 svn rev kdebase: 907819 I noticed that there's no kephald started after logging into kde4 (using kdm/kde4 and startkde script). I started it manually. The kephald output from adding a new screen is this: [CRTC] Event... Changed mode Changed size: QSize(1680, 1050) [OUTPUT] Got event for "VGA" crtc: 73 mode: 145 rotation: 1 connection: 0 Setting CRTC 73 on output "VGA" (previous 0 ) possible: (75, 77, 78) CRTC outputs: (75) output changed: 75 XRandROutput::_changed() true true QRect(1440,0 1680x1050) OutputScreens::rebuildScreens() As I said before, plasma doesn't print anything when adding the output. Not even if I restart plasma after manually staring kephald.
Turns out that this is caused by kephal not getting the notifications right. Patch pending on kwin mailinglist and I'll make sure it'll get in before the 4.2 release. Closing this as dupe of the xrandr bug, as plasma is not at fault here. *** This bug has been marked as a duplicate of bug 173017 ***
