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 Ubuntu Desktop Bugs, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1828775 Title: [amdgpu] High memory consumption To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1828775/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
