Xorg memory leak on 14.04

[Yosha872]

Same kind of issue as : "Xorg memory leak on trusty" https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1272338

After browsing a lot (Firefox 31, Opera 12), after more than 10 hours Xorg uses over 1 GB (some times up to 2 GB). I have 8 GB RAM.
It seems to me that the system monitor increase the memory leak.

I'm on Linux Mint 17 (64 bits Cinnamon).
APU AMD Athlon 5350 (+ driver AMD Catalyst 14.4).

By the 'system monitor' I mean the software (v3.6.0) that shows graphs about CPU and memory.

[Chris Wilson (ickle)]

Use xrestop to see how much memory X is using on behalf of its clients.

Hello. After 8 hours running, Xorg is 1,9 GB.

[Pekka Kola (pekka-kola-m)]

I guess this is the same bug I've reported (Bug #1314787)

[Federico Tello Gentile (federicotg)]

I had the problem with Ubuntu´s catalyst version, but it seems to be fixed with Catalyst 14.9.

[Will Lucas (mevatron)]

I also was having this problem. As mentioned by @federicotg, I upgraded to the AMD Catalyst 14.9 driver, and I have been running Ubuntu for about 6 days 24/7 with no leaks (at least not noticeable anyway). Xorg stays around 250MB of usage on average for me now.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[yehonal (hw-2)]

i've the same problem on 14.04.1. Xorg eats lot of RAM after few hours...is there any fix?

[Brian Trotter (brian-trotter)]

Reverting from the fglrx (proprietary) driver to the xserver-xorg-video-ati (open source, tested) driver solved the problem for me.

[David (bigdaveberg)]

Can confirm the bug still exists, causing massive memory leaks for me as well.

[bmaupin (bmaupin)]

Same problem with Xubuntu 14.04.3. I switched back to the xserver-xorg-video-ati driver to see if it fixes the problem.

This was while I was still using fglrx:

After switching back to xserver-xorg-video-ati, X is using much less memory:
