Description: After upgrading from KDE 4.4.3 to 4.4.4, KDE does not setup the Desktop coordinates correctly on my asymmetric 2-monitor setups.

For example, right now the task bar on my high-resolution monitor is the width of my low-resolution monitor. Additionally, my high-resolution screen acts like it has the height of my low-resolution screen. For example, Songbird acts like it has hit the bottom of the screen when it still has about 1/3 of the screen left to go. More awkward is that the "Start menu" appears 1/3 up the screen as well even though the task bar is at the very bottom of the screen. The same problem occurs with notifications.

I was able to fix some of the problems by moving the second monitor "under" the first monitor in the Display setup.

All of this works fine in KDE 4.4.3.

Additional info:
* kdebase-workspace 4.4.4 (and kdebase-plasma?)
* two monitors where one has significantly higher resolution than the other


Steps to reproduce:
1. Hook up two monitors of different resolutions
2. Refresh KDE to use both of them
This task depends upon

What about with kde 4.4.5?

Multiple monitor support seems to be working OK. After the upgrade to 4.4.4, it was unusable until I wiped out all of my KDE settings and re-created them from scratch. Since then, things seem to be working OK. The length of the task bar was still wrong until I went into its settings and had it fill the width of the screen.

So I'm not convinced that KDE is 100% multiple monitor friendly. It's frustrating that I have to run xrandr manually (or by way of hot key) every time I unplug/plug in a monitor in order for KDE to detect the change.

The most frustrating thing about KDE (that I haven't checked in 4.4.5, but it was still a problem in 4.4.4) is that after unplugging a monitor, running xrandr, and accepting the new display prefs that show the old monitor grey'd out, the Desktop coordinates still stretch onto the monitor (and old programs running on the old monitor stay over there). Because the second monitor is grey'd out in the settings, I cannot manually disable it until I plug it back in. The only fix is plugging it back in, disabling it, then unplugging it (and possibly running xrandr). But that sounds like a different bug (and something I've learned to live with).

I did respond. Your request was on the third, I responded on the fifth.

KDE's multiple monitor support in the most up-to-date version of KDE is still poor. After KDE detects a monitor has been unplugged, it disables it (as it should), but it does not adjust the desktop coordinates. Consequently, programs get "stuck" on the phantom monitor and the user is allowed to drag things over to the phantom monitor even though the monitor is "Disabled" in the display settings.

The only way to truly disable the monitor is to plug it back in then go into KDE's display settings and manually disable it (while it's plugged in). That will adjust desktop coordinates correctly so that programs will not be able to be dragged into the phantom monitor after it's unplugged.

This problem did not seem to be a problem in much earlier versions of KDE. It has been a problem for 4.4.4 and 4.4.5, and it may have been a problem for 4.4.3.
