--- Comment #16 from Alistair Buxton <a.j.bux...@gmail.com> --- The only difference between 4.14.1 and 4.14.2 that I can reproduce is that 4.14.1 often results in a partially or completely blank screen after a monitor change, which is caused by bug #15971. In both cases the sequence of events is the same: - When I first connect the external monitor, the taskbar is constrained to the smaller of the two monitors. - When I close the laptop, I see this in the log: xfce4-settings(displays): UPower lid event received (open -> closed). xfce4-settings(displays): Normalized CRTC 64: size=1920x1200, pos=0x0. The taskbar is no longer constrained to the internal display because it has been disabled. The external is now the only active monitor. - When I disconnect the external I see this: xfce4-settings(displays): No active output anymore! Attempting to re-enable the internal output. xfce4-settings(displays): Normalized CRTC 63: size=1920x1080, pos=0x0. Here the internal display is re-enabled because there are no other displays left. - When I reconnect the external: xfce4-settings(displays): Normalized CRTC 63: size=1920x1080, pos=0x0. xfce4-settings(displays): Normalized CRTC 64: size=1920x1200, pos=0x0. The newly connected external is enabled, and the internal display is already enabled. Now the taskbar is constrained to the smaller display. - When I open the laptop: xfce4-settings(displays): UPower lid event received (closed -> open). Here, the displays are not reconfigured, because they are already in the correct state for external connected and laptop open. - Finally when I close the laptop again: xfce4-settings(displays): Normalized CRTC 64: size=1920x1200, pos=0x0. Now external is the only connected monitor and the taskbar is at the bottom of the screen. -- You are receiving this mail because: You are the assignee for the bug. _______________________________________________ Xfce-bugs mailing list Xfce-bugs@xfce.org https://mail.xfce.org/mailman/listinfo/xfce-bugs
