I have an Ubuntu desktop install and I noticed that I can't communicate over any network interfaces until I actually log in and they are activated.
Is there any way to have NetworkManager activate all interfaces at boot time?
I've noticed lately that the performance of the UI in Gnome 3.36.2 seems to decay with uptime.
The most obvious manifestation is that over time, window animations have a delay and feel "sticky". Applications themselves seem unaffected. When I tell gnome to switch workspaces, there's about a half second to full second delay before the animation happens. This also applies to things like pressing the meta key to show all my windows or pressing alt-tab. Each one appears to share the same delay.
I'm running a fairly unremarkable desktop setup using vanilla gnome on Ubuntu 20.04.
My research on this issue seems to indicate that there were memory leak issues in 18.xx versions of the OS, but that those were supposedly fixed. The only thing I can conclude at this point is that a new issue has emerged, there was a regression, or the original fix didn't work.
The animation delay is sapping productivity to the point that I eventually have to reboot my system. The gnome-shell process definitely leaks over time as it starts around ~300mb and if left for a day will sit at ~600mb or more.
Regarding my overall hardware and nominal state of my system, I'm experiencing this issue even as I'm creating this question. I'm running the stock/vanilla gnome desktop, not the ubuntu customized one.
My system has 32gb of RAM, only 6gb of which are in use currently. My CPU usage fluctuates across 12 vcores up to 20% max. I have an RTX 2060 for my GPU.
At least as best as I can tell, I see no issue with the amount of resources gnome-shell is getting right now. ?

I don't believe my system is underpowered or in any way misconfigured such that this leak is as a result of my own doing.
When running in Windows, I'm able to use multitouch gestures with my touchpad. Unfortunately, when running on Ubuntu 19.10, I can't do a two-finger back gesture in my browser or any three or four finger gestures.
The device appears to be detecting fine and again -- multitouch works in Windows. What would I need to do to get it working the same under Ubuntu?
Trying to connect to the time capsule, I've explicitly set my username and password using a separate OSX machine. So I know all of my credentials are correct.
For some reason though, when I try to connect through nautilus, I get the message:
Got error "kFPAuthContinue" from server
Obviously Apple is just being difficult here, but I'd love to be able to read and write files to my airport time capsule from Ubuntu computers.
How do I determine whether a particular running Ubuntu system was booted using EFI/UEFI, or BIOS?
Is there a places menu in Unity, similar to the one in the old gnome interface? I really liked having such quick access to remote shares.
