<div dir="ltr">I been tracking some display problems while upgrading Fedora from 16 thru 18 and while we have to disable nouveau and use nvidia's own drivers, this track fixed most of the symptoms you described under 17 and which had been mostly addressed as selinux permissions in F 18. <div>
<br></div><div>This can be done through yum as explained here <a href="http://www.if-not-true-then-false.com/2013/fedora-18-nvidia-guide/" target="_blank">http://www.if-not-true-then-false.com/2013/fedora-18-nvidia-guide/</a> set selinux to permissive mode for this install to avoid issues.</div>
<div><br></div><div>At this time for us there are re occurring errors in desktop switching. It looks like this may be an issue with colord carried forward from 17. </div><div><br></div><div>When the gui switcher exits, a colour term is initialized with a quick "Manager" error displayed before the login gui takes over. Sometimes random images are pixilated and displayed as fragments on the screen and sometimes it hangs and we have to reboot. Recent updates seem to have corrected most of this for us, so as I say this looks like a colord hangover.</div>

I have a lot of windows and tabs.<br>
<br>
Firefox is huge, lots of windows, but Resident Size is only 1.5GiB out of<br>
6 GiB that the hardware has. Nothing else is near that.<br>
<br>
Firefox is taking 50% of a core, but heck, I've got four cores. Nothing<br>
else is near that.<br>
<br>
I don't think that anything is eating disk or network bandwidth.<br>
<br>
So why is my desktop window manager laggy? Dragging a window or creating<br>
a new one isn't instant.<br>
<br>
What should I be monitoring / measuring?<br>
