It's on restarting. 🐛🧹 ⚠️ This bug has been in NEEDSINFO status with no change for at least 15 days. Please provide the requested information, then set the bug status to REPORTED.

Unfortunately, Wayland does not yet remember apps positions, per bug 15329 Native Wayland windows are not allowed to determine where to place themselves on screen at all; the compositor does this. That means the compositor could implement a "remember window positions" feature and it would work automatically for all native Wayland app windows. This is tracked in Bug 15329. Until that happens, the compositor instead simply places all windows according to the placement policy. *** This bug has been marked as a duplicate of bug 15329 *** (In reply to TraceyC from comment #5) > Unfortunately, Wayland does not yet remember apps positions, per bug 15329 > > Native Wayland windows are not allowed to determine where to place > themselves on screen at all; the compositor does this.

So in my sense, it's a different bug : on wayland, the windows always open on left screen, and not on main screen.

In an earlier comment, you said that the problem happened when restarting the computer. If there's also a problem that during a normal session, all window only open on the non-primary screen, that's a different bug. Please open a different report for that. Thanks. (In reply to mysterty from comment #6) > So in my sense, it's a different bug : on wayland, the windows always open > on left screen, and not on main screen. There is no "main screen". KWin puts windows on the screen you last interacted with - moved a window to, moved the mouse on, that stuff.

So in my sense, the bug is that "main screen" definition is not working.

On configuration tool : go to screens, select your screen, apply "primary" (or main, or whatever your traduction says) |
