Hi! No idea if this is a significant discovery or a statement of the obvious but will post anyway. Running Ubuntu 16.04 here; for whatever reason for the past roughly six months I have been been having random lock-ups: display freezes except for the mouse point (usually) and the processes (DejaDup, the Virtual Machine running Windows XP, etc.) also usually continue to work.
Recently found a work-around: boot, log-out (via the gear icon at the upper right), log back in but first click on the foot icon and select a different option. Here I have Gnome, Gnome Flashback (Compiz), Gnome Flashback (Metacopy), and Ubuntu (default). I selected the ‘Compiz’ one and my lockups magically went away! <cartwheels!!> According to the post I was following this reduced/eliminated video hardware acceleration. ...The side effect, at least for me, is area screen shots (Shift_PrintScreen) now have the pink overlay. What I’m wondering is in Post #31 BDSword suggest an increase of the 200 value in “g_timeout_add (200, emit_select_callback_in_idle, cb_data)”, something about a delay timeout. I’m wondering if there is a connection between this value and it has effectively been slowed down by my changing from the Ubuntu option to the Compiz option, the latter supposedly turning off video acceleration. Just a WAG, but may help the developers and troubleshooters to find the solution. (Now to try increasing that 200 value – to what??! And from my notes what file?) -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-screenshot in Ubuntu. https://bugs.launchpad.net/bugs/743176 Title: Pink layer on taken screenshots (gnome-screenshot) Status in gnome-flashback package in Ubuntu: Confirmed Status in gnome-screenshot package in Ubuntu: Confirmed Status in gnome-utils package in Ubuntu: Fix Released Bug description: Binary package hint: gnome-utils After having taken a screenshot of a part of my screen (gnome- screenshot) which is marked/shown by a pink layer, this pink layer can be seen on the screenshot itself.
