GNOME Bugzilla – Bug 776321
Position of gnome-system-monitor is not remembered on screen when under Wayland
Last modified: 2017-05-01 15:10:17 UTC
I am running Ubuntu GNOME 16.10 with GNOME 3.22 and since switching from Xorg to Wayland via the login screen I have noticed that with the gnome-system-monitor that it always starts off on the left hand side of the screen, and I like to have it on the right hand side, so that is where I always put it. However, if I restart it, it always goes back to the left side rather than remembering where it was before like it does if I close it when it is fullscreen. So far it seems that this issue only affects the gnome-system-monitor, all other applications behave as expected in regards to this matter. I originally reported this issue here: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1650684 But thought I should also do so upstream.
gnome-shell or mutter don't remember window positions, it's up to applications to save/restore state and position. However on wayland, applications don't have a "global" view of the screen, and applications cannot (by design) position windows through "global" coordinates (only relative to other windows from the same application).
