I have a Lenovo Thinkpad T460 with an Intel i7-6600U chip, and two external monitors connected to a docking station. Everything works fine if both external monitors are configured in landscape mode in KScreen (i.e., no rotation). However, once I put one of the monitors in portrait mode (90° rotation), it turns black. I can see the mouse cursor on it, but windows on that monitor are invisible. I also think that the right-click menu still works, but is invisible, because of the following: I right-click somewhere on a working monitor -> context menu appears I right-click somewhere on a working monitor -> context menu disappears I right-click somewhere on a non-working monitor -> no visible change (invisible context menu appears?) I right-click somewhere on a working monitor -> no visible change (invisible context menu disappears?) Reproducible: Always Steps to Reproduce: 1. Configure an external monitor with rotation Actual Results: Monitor turns black, nothing but the mouse cursor is visible Expected Results: The desktop, windows and the right-click context menu are visible
I just tested it with the internal laptop monitor, same result. Black screen with only the mouse pointer visible.
Thanks for the bug report, Tom. Can you drag open windows onto the "non-working" monitor?
Hi Sebastian, I can drag windows onto the non-working monitor. Last week the part of them that was on the non-working monitor became invisible. But they were there, and I could activate them by clicking at their invisible part. Today I installed some updates from the Frameworks 5 repository (http://download.opensuse.org/repositories/KDE:/Frameworks5/openSUSE_Leap_42.1/) and a kernel update (4.7.4 -> 4.7.5), and now windows and menus on the vertical screen are visible. However, the screen is still very slow. I can literally see how it repaints the screen from top to bottom when I drag windows across it. Also the background when removing a window is not repainted correctly, leaving black areas instead. Animations/desktop effects are slow on other screens as well as long as one screen is vertical. Thanks for looking into this, Tom P.S.: I will be traveling for the rest of the week and probably not be able to do further tests until next week.
Thanks. I'm reassigning this to kwin, so Martin can have a look. It's not a kscreen problem since the output is set up correctly.

The output indicates that compositing is not used. In that case KWin is not responsible for the rendering. The slowness might come from X then or might even be that the hardware is not capable of doing this setup. In case you are using the Intel xorg driver, try switching to the modesettings driver.
Hi Martin, I can confirm that after uninstalling the xf86-video-intel package and rebooting the portrait mode monitor works. I'm closing this bug. Thanks, Tom
