It’s 16.10/GNOME/Wayland, did not happen in 16.04 I was previously on 16.10 KDE/X where it does not happen either. When Wayland is used, certain actions halts i915 and the cpu.
When GNOME 3.20 was in staging, LibreOffice was so bad it could not be used. Now it only halts when a Libreoffice window is dragged across the hidpi display. If that isn't done, the system does not halt. It is practically certain to be an i915 dri problem It may be related to GtkStyleContext and having multiple displays both low dpi and hidpi These two applications, when in gtk3, do something that halts in i915 One could fix the bug in i915 or make LibreOffice not do whatever it is that causes the halt -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1647084 Title: i915 multiple display halt system when moving windows Status in linux package in Ubuntu: Incomplete Bug description: When moving certain windows across displays, the system may suddenly halt and has to be powered off SYMPTOM Either the window being dragged suddenly jumps to the top-left position of the external display to the right (ie. display 2, the first external display) and the system halts, or the system halts while the window is being dragged across the internal display Affected applications: Virtual Machine Manager, Vuirtual Machine window LibreOffice Writer Other problem If a Libre Office Writer window is opened on the internal display, ie by launching LibreOffice Writer, the system halts. IMPACT Critical: in-app data loss, fsck data loss, forced system reboot GETAROUND Do not drag halting apps between displays To move a LibreOffice Writer window, close it, and launch LibreOffice from a terminal window on the destination display. On command libreoffice --writer, LibreOffice opens on the display where the terminal window is located. For Virtual machines, close the window, move virtual machine manager to the destination display and open the virtual machine window there. The halt is similar to how the system halts when the kernel command line parameter i915.enable_rc6=0 is missing.
