Thanks for asking. I think I’ve had it for a week, and luckily no issues so far. I use it sparsely though, I always have on-demand mode. But I imagine Ubuntu Studio has important differences from Ubuntu?

Happy to have helped! I’m myself testing 580 now, fingers crossed :)

I don’t know if it’s the same in Ubuntu Studio, but in Ubuntu and derivates you can launch sudo software-properties-gtk or sudo software-properties-qt from a terminal. In the window that appears, choose the tab ‘Additional Drivers’. There you can choose the Nvidia graphic drivers you prefer among older and newer versions. Good way to roll back.

Apologies if this was obvious 🙏

Great to hear! All’s well that ends well :)

Now I understand, thank you for the explanation!

Thank you for this comment. So Unbound does only DNS caching, without really resolving? I think I’ve completely misunderstood its purpose.

I’m starting to think that I’ve misunderstood what Unbound does. I thought I’d be a replacement for a DNS resolver (like CloudFlare). But from the replies here I’m starting to think it isn’t?

Thank you for the warning! I’ll know it’s expected then :) In my case I’d like to use it more or less independently of the network I’m in, that’s why I’d like to take a single-machine approach.

Thank you, I see the advantages of a network approach. In my case it’s just two laptops in my network, and I’m also thinking of the case when I’m using the laptop in some other networks.

X1 Carbons of several generations have been notorious for their Thunderbolt defects, which appear after a while. For instance this or this (sorry for the Reddit links), and there are others related to connecting to screens. Right these days I’m dealing with the Thunderbolt-charging defect in my Gen 9. Luckily still under warranty.

Best of luck with your problem! I suggest you use your warranty if still active (and better with on-site assistance than sending the thing).

Yes, it turns out one can change session at login! Turns out Wayland doesn’t support my tablet, so I’ll stick with X11.

Thank you. This live USB defaulted to X11 for some reason, but I was able to change to Wayland after the session started.

It turns out Wayland doesn’t support my touch/pen-screen: "“Unsupported platform detected. Currently only X11 is supported”. So X11 it is.

Cheers! Apparently Ubuntu uses the relatime setting.

So what are the atime settings in a Linux distribution like Ubuntu?

Thank you! didn’t know about that command.

Edit: explicitly installing 10.1 with

sudo apt install wine-staging=10.1~focal-1 wine-staging-amd64=10.1~focal-1 wine-staging-i386:i386=10.1~focal-1 winehq-staging=10.1~focal-1

worked.

Thank you for the help!

But I can’t remove wine-staging, at least not via apt:

$ sudo apt remove wine-staging-i386

You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies.
 wine-staging : Depends: wine-staging-i386 (= 10.2~focal-2)
                Depends: wine-staging-amd64 (= 10.2~focal-2) but 10.2~focal-1 is to be installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

So no go there. --fix-broken doesn’t work either:

Any idea on how to remove Wine manually, bypassing apt?

The problem is that the whole apt system seems to be broken. It doesn’t let me install other packages, and I can’t even uninstall wine. So I wonder if any fixes from wine will work. It looks like this needs the user’s manual intervention.

but sudo apt --fix-broken install does not solve anything…

Cheers! Got a bit clearer now.

Appreciated if someone can explain what is the problem and its context in simple terms 🙏

I understand the GNU “framework” is built on free, open source software. So I don’t understand how one can “discover” that there were pieces of non-free software there… They were put there by mistake?
