Hi,

Just downgraded kernel 3-16 -> 3.14.39 and I followed GVS's instruction above.
And after that I installed
http://www2.ati.com/drivers/linux/amd-catalyst-omega-14.12-linux-run-installers.zip

See this Xorg process's memory comsumption:

nuhapumppu Desktop # uptime; pmap 1564 | grep total

As you see, there is no memory at all. Uptime is over 11 hours.
This is kernel related issue definitely.
When huge Xorg memory leak was exist, the memory consumption was several GBs so far (11 hours)

So kernel 3.14.39 cured my system.
Need to know which kernel commit(s) fix this memory leak.
So I don't update kernel to 3.16 until this leak is fixed. I stay 3.14.xx branch.

Big thanks to GVS!!!

Title:
  Memory leak

Status in fglrx-installer package in Ubuntu:
  Confirmed

Bug description:
  I upgraded my PC from Ubuntu 13.10 to 14.04 (released one). After
  upgrade I found the PC slows down soon even without apps running on
  it. When checking with system monitor I found all the physical memory
  was full and the swap file was in use (which never happened with
  13.10). I restarted the PC and left it alone. After six hours memory
  consumption of xorg went from original 250MB to 1,3GB. I guess there
  is a memory leak in the process.
