Install Arch Linux from scratch so it is brand new nothing is modified 2. Install KDE and activate it via systemctl enable kdm.service; login 3. Configure Seperate X Screen via Nvidia-Settings 4. Press Alt + Tab Actual Results: Task Switcher occasionally shows up, if at all on the wrong screen...doesn't even take into account which monitor the cursor is on. Expected Results: Task switcher to show up on the active screen in question. 1339877 1 mgraesslin 2013-02-10 08:30:09 +0000 > 3. Configure Seperate X Screen via Nvidia-Settings why are you using this feature? If you want to have proper multi-screen don't use that. 1339881 2 thomas.luebking 2013-02-10 08:54:08 +0000 partial dupe of #256242, there's a patch attached. also see https://git.reviewboard.kde.org/r/107853/ This does fix the problem halfwise, the situation about kglobalacceld is extensively discussed on the dupe. Needs rebase to current master and on top of the present Xcb wrapper class. *** This bug has been marked as a duplicate of bug 256242 *** 1340136 3 nwenclaff 2013-02-10 20:19:26 +0000 I use separate X Screens because if I use twinview the full screen flash shows on the second monitor and not the 1st monitor like I want it to - also twinview will occasionally start applications up in the wrong monitor , If i use separate X Screens the app will show up in the monitor it was selected from and is non transferable to the other monitor. 1340139 4 thomas.luebking 2013-02-10 20:24:39 +0000 still dupe, the problem is more complex and all the info is over there. With 4.10 you'll be able to enforce a screen for windows by windowrule. since nvidia also has complete xrandr support now, i suggest you'll give twinview another try then. *** This bug has been marked as a duplicate of bug 256242 ***
