[Desktop-packages] [Bug 1906906] Re: Memory leak in X.org
Leaks in the Xorg process are usually the fault of applications. Because application resources exist in the Xorg process and are allowed to outlive the application itself. One known cause I can think of is LibreOffice. So please try logging out and in again and never starting LibreOffice. If that doesn't fix it then please follow the same steps with all your other big apps to try and find the cause. ** Package changed: xorg (Ubuntu) => xorg-server (Ubuntu) ** Package changed: xorg-server (Ubuntu) => ubuntu ** Changed in: ubuntu Status: New => Incomplete -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1906906 Title: Memory leak in X.org Status in Ubuntu: Incomplete Bug description: Hi, I think I've found a memory leek in X.org. The memory usage goes up and up (I was at ~3.4GB when I decided to open this bug report), and barely goes down when I close X clients (closing half of the windows brought me down to 3.3GB). https://paste.gnugen.ch/raw/oUhi I'm using Ubuntu 20.04 LTS and I am kinda stuck with X.org for Wacom tablet support. This is quite annoying and made the system hang twice. (The system ran out of memory, which caused 100% CPU usage while Linux was trying not to kill anything, and a force reboot was required). I had to add more swap, because 8GB + the default 2GB of swap weren't enough.
