Bug Description

When my 2nd Asus (Ancor) display is in portrait mode and is set to be to the left of my centered landscape display in extended mode, moving the mouse to roughly the left 20% of my landscape display will show a mouse cursor on my landcape display AND portrait display at the same time. Oddly moving a window into this area only shows on the landscape display.

Thank you for taking the time to report this bug and helping to make Ubuntu better. The issue you are reporting is an upstream one and it would be nice if somebody having it could send the bug to the developers of the software by following the instructions at https://wiki.ubuntu.com/Bugs/Upstream/GNOME. If you have done so, please tell us the number of the upstream bug (or the link), so we can add a bugwatch that will inform us about its status. Thanks in advance.

I've just upgraded ubuntu to 17.10 and got this bug =(
I have 3 monitors (1 laptop and two 2560x1440 monitors)
first is the laptop screen, second is rotated vertically screen and next one is not rotated normal screen. when I move cursor on third screen I can see rotated reflection of cursor on second (rotated) screen. It really annoys me, because I cann't work now. =(

I have a 3 screen setup on a notebook with intel graphics. The left one is in portrait view, the center one is in normal view and right is in normal view (buildin), mostly turned off.
When the mouse is in left side of the center monitor it shows also on the left monitor bottom.

The same problem is better described here: https://askubuntu.com/questions/964239/ubuntu-17-10-cursor-mirrored-on-second-screen

I can confirm the exact same behaviour in my 2 monitor setup, one in portrait mode to the left and one in landscape to the right. I have just upgraded to 17.10 and, oddly enough, the problem only happens when the open source Nouveau driver is in use. If I switch to the proprietary nVidia driver, the second cursor does not appear, as expected.

Daniel van Vugt (vanvugt) wrote :

I doubt this bug is driver-specific. A rotated screen might get "software" (GL) cursor rendering by default in Wayland sessions (I am guessing since we did the same in Mir). And the hardware cursor is used on non-rotated screens. The two should co-exist and only one display at a time, so that's no excuse, just a possible explanation.

One reason why the problem might appear to go away with the proprietary Nvidia driver is because that uses Xorg by default. So it avoids all such issues that are peculiar to the Wayland/eglnative case.

Confirmed - rotated second screen causes duplicate cursor. Luckily the second one is un-rotated, so it is easy to know which is the "real" cursor.

Description of problem:

I have three displays connected to a Radeon RX480. One is 3840x2160 (landscape), the other two are 1200x1920 (portrait left and right, respectively). The 4k display is indexed as the third one in the Displays panel of the Settings app, and arranged as the rightmost of the three displays.

After upgrading to Fedora 27, when the mouse pointer is near the left edge of the 4k display, it also appears on the adjacent 2k display. The extra pointer is displayed as if the display was in landscape mode, so it appears rotated relative to the display contents. It seems to be just a display bug; click events go correctly to items on the 4k display.

Version-Release number of selected component (if applicable):

wayland-1.14.0-1.fc27
gnome-shell-3.26.2-1.fc27

How reproducible:

Always.

Steps to Reproduce:

I haven't tried to reproduce from a fresh config. Hopefully it's reproducible with a similar config.

If I unplug one of the 2k monitors I can still reproduce if the remaining 2k monitor is in 'portrait left' but not 'landscape'. So the issue should be reproducible with two screens.

I "fixed it" by using Xorg instead of Wayland.

I currently have this problem after a system upgrade from 26 to 27.
I have a triple monitor setup, with the leftmost monitor set to "portrait right" (like most people commenting)

My current work around is to align the bottom of my left monitor (in portrait right) to the bottom of my center monitor (in landscape)

If I align the top, so that there are more pixels below my center monitor the "ghost" cursor appears. After some testing, I found that this only happens in "portrait right" and "portrait left" on the left-most monitor. Adjusting the position and orientation on my right monitor doesn't have an affect.

Correction: I updated my system and it re-installed the nouveau drivers, which is when the bug appeared. I re-installed the proprietary drivers and the bug has disappeared.

I am also affected by this 'feature'. I have 3 1920x1200 displays and primarily use my i7-6700hq's integrated graphics. I also have a discrete 960m; however, I don't believe it's in use. I am running Fedora 27 with Gnome 3.26.2.

The issue only occurs with my leftmost monitor when it's set to portrait mode. Feel free to contact me if I can help troubleshoot this.

I'm also affected:

x2 1920x1080 screens (left in portrait right mode and left in landscape mode)
OS: Arch Linux
GNOME: 3.26.2
Wayland: 1.14.0
Weston: 3.0.0
Graphics card: Intel HD Graphics 530 (There is a secondary nVidia GTX 1050 but it is disabled and power disconnected)

In my case the mouse from the top left corner (aproximattely a quarter of the screen area) of the landscape screen replicates onto the bottom left of the portrait screen, in landscape orientation. Actions do not affect the portrait screen.

This issue does not happen with the reverse layout: left screen in landscape mode and right in portrait right mode.
