Hi, recently I tried installing 14.10 on the same machine on different partition and it seems that problem with rotation + slowdown is gone. So as a next step was upgrading my trusty Trysty to Utopic. Right after upgrade (and before login) I deleted monitors.xml file from my working profile (user) and viola problem is gone. So gar so good, I would like to say. So the problem was related to monitors.xml or updates between my last try and this one, or both. Can't say whether slowdown is gone as I'm using the system for just about one day. Will report back with the results.

And after each release I hope it will be fixed, but it doesn't happen. A little intro: I'm using Ubuntu for work, I rarely shutdown the computer I rather put it to sleep mode, in worst case it's hibernate. I have loads of apps opened at the same time. I use external monitor as well. Computer is Dell XPS15 L521X, 16Gb RAM, 120GB SSD + 1TB HDD. As a graphics card I'm using builtin intel HD4000, I have GF GT640 as well but it's disabled using bbswitch. Symptoms are that after some time compiz slows down a lot while using it. Usually it's no more than 2 days and it's slow again. When I restart Unity (setsid unity) it's back to full buttersmooth speed with the same apps opened which leads to conclusion that compiz can handle the load very well. Maybe it's mesa, maybe it's compiz or unity itself that slows it down - but I'm no pro to tell. With 14.10 release I observed very interesting behaviour. I have FHD builtin monitor and FHD external monitor rotated counterclockwise. Let's say I started computer yesterday in the morning, it was working smooth with both monitors and single display, I suspended computer got home unsuspended and it seemed sluggish (only graphics part of course). I ran glxgears (I know I know...) and it showed ~ 50FPS which is slow, because running the same before suspend gives near 60FPS (refresh rate). Now I come back to work and run it on single builtin display - ~ 50 FPS, I connect second FHD dispplay and FPS are back to 60 and it's running buttersmooth again. So it seems that mesa/compiz/unity have some strange refresh rate problem detection maybe... 2 FHD displays seems to be twice the job compiz has to do over single display which is strangely slower... Please advise how can I help solving this, do I need to run compiz debug version or what can I exactly help technically (applying a patch, compiling compiz myself, you name it...). I know the standard procedure of logs etc., I'm afraid that won't help much in this situation. I looked at logs and there's nothing suspicious, at least to me.
