Yes, you definitely have a leak there. Thanks for the extra info. It's worth remembering you need to ignore 'VIRT' in ps, which is the same thing as 'VmSize' in /proc/PID/status. Because that huge number is virtual address space and not real memory.
The important number to look at is VmData in /proc/PID/status. According to your most recent feedback the VmData value is between 1.4GB and 2.6GB. Definitely too high so definitely a bug. Next we need to figure out what is special or unusual about the system that leads to such high memory usage. The only special thing I can see right now is that you are using the AMDGPU kernel and Xorg drivers so we need to test whether that is the cause. I wonder if you could try disabling the amdgpu Xorg driver? Please try moving or deleting: /usr/share/X11/xorg.conf.d/10-amdgpu.conf then reboot. If that doesn't work out then you can restore it with: sudo apt install --reinstall xserver-xorg-video-amdgpu You may also want to try blacklisting amdgpu in the kernel: https://unix.stackexchange.com/questions/360709/how-to-blacklist- amdgpu Once you think you have successfully disabled the AMDGPU Xorg driver, please attach another copy of Xorg.*.log ** Summary changed: - High memory consumption + [amdgpu] High memory consumption -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1828775 Title: [amdgpu] High memory consumption Status in gnome-shell package in Ubuntu: Incomplete Bug description: High memory consumption ProblemType: Bug DistroRelease: Ubuntu 19.04 Package: gnome-shell 3.32.0+git20190410-1ubuntu1 ProcVersionSignature: Ubuntu 5.0.0-13.14-generic 5.0.6 Uname: Linux 5.0.0-13-generic x86_64 ApportVersion: 2.20.10-0ubuntu27 Architecture: amd64 CurrentDesktop: ubuntu:GNOME Date: Mon May 13 09:47:53 2019 DisplayManager: gdm3 ExecutablePath: /usr/bin/gnome-shell GsettingsChanges: b'org.gnome.shell' b'app-picker-view' b'uint32 1' b'org.gnome.shell' b'favorite-apps' redacted by apport b'org.gnome.desktop.interface' b'gtk-im-module' b"'gtk-im-context-simple'" InstallationDate: Installed on 2019-01-10 (122 days ago) InstallationMedia: Ubuntu 18.04.1 LTS "Bionic Beaver" - Release amd64 (20180725) SourcePackage: gnome-shell UpgradeStatus: Upgraded to disco on 2019-04-25 (17 days ago) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1828775/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
