DeepDeadpool's questions

On Ubuntu 21.10, dolphin-emu was accessible via a simple sudo apt install dolphin-emu. I didn't need to add a ppa or anything like that, despite Dolphin's official instructions. I suspect this is probably because it was available via Debian. edit it was available in Ubuntu 21.10 Universe repo, and not in Debian main

This no longer works in Ubuntu 22.04, and my existing dolphin-emu was removed when I upgraded. When I try to install it I'm met with this message.

Package dolphin-emu is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

So clearly it was here, but the upgrade to 22.04 from 21.10 removed the binary from my system. The PPA also fails with this error

So how is one expected to install dolphin-emu on Ubuntu 22.04?

It appears that when I upgraded my Ubuntu to 22.04 it carried the old screenshot utility with it, but I also have the new GNOME 42 screenshot way when I push my Print screen key on my keyboard.

So when I type "screenshot" in the activity overlay, I get the old Ubuntu 21.10 way.

When I hit my Print screen key, I get the new Ubuntu screenshot UI.

Is there a way to unite the two, so that typing "screenshot" in my activity overlay brings up the new GNOME 42 screenshot UI?

I upgraded my installation using the do-release-upgrade utility, if that makes any difference.

I am confused about how Ubuntu stores user-selected wallpapers.

I have some pictures I use as wallpapers. We'll call them walla and wallb. Both originate from an encrypted drive that is not automatically mounted. walla is the active wallpaper, but is not in ~/Wallpapers, but wallb is.

So I think "Ok, so Ubuntu must have a place where it copied walla", so to experiment I set wallb.png as the wallpaper and then removed it from ~/Wallpapers. This caused the background to disappear. This left me confused as to where it stored walla, because that encrypted drive I mentioned was not mounted.

Could someone please tell me where Ubuntu stores the active wallpaper and how it goes about deciding when to copy user-provided wallpapers to various destinations?

I'm trying to upgrade from Ubuntu 19.10 to 20.04.

I have my Software & Updates set to Notify me of a new Ubuntu version: For any new version, but I didn't see a notification.

I then ran the following commands, and got some weird output.

master@master-desktop:~$ sudo do-release-upgrade -cd
Checking for a new Ubuntu release
New release '20.04' available.
Run 'do-release-upgrade' to upgrade to it.

master@master-desktop:~$ do-release-upgrade 
Checking for a new Ubuntu release
No new release found.

Why is it not capable of upgrading to 20.04 when the -cd flag clearly shows it?

I'm using the Linux build of PCSX2 on Ubuntu 19.10. This is currently version 1.5.0-0.

When I go to GS plugins, I see 3 options.

GSdx (GCC 8.2.0 SSE4.1/AVX) 1.1.0 [libGSdx-SSE4]
GSdx (GCC 8.2.0 SSE2/AVX) 1.1.0 [libGSdx]
GSdx (GCC 8.2.0 AVX2/AVX2) 1.1.0 [libGSdx-AVX2]

Could someone please explain what GSdx, SSE* and AVX* are, and what the differences between these plugins is?

I hope this isn't too broad, but I'm was looking for a non-proprietary alternative to nautilus-dropbox and I discovered rclone. It's pretty neat on its surface and I can see some potential.

The command I run to sync my dropbox and local directory is

rclone sync -P ./ dropbox:/

And it takes a long time checking files that I haven't modified - even when I run this command twice in a row. The files that have changed are quickly identified and transferred quickly, but it seems to perform thousands of checks on other sub-directories and files that haven't changed.

I'm looking for some approaches to speed this up a bit. Barring that, is there another alternative to nautilus-dropbox on Ubuntu 19.10? Perhaps one available from the apt-repositories?

I powered on my Ubuntu computer and see "your computer needs to restart to finish updating."

This indicates that something automatically updated - therefore this is something that wishes my computer to act without first receiving my command.

What could be responsible for this, and how do I kill it?

My right click on my track pad is broken. Can I use Alt+Left-click as a substitute?

I know that, with systemd, any scripts put in /lib/systemd/system-shutdown/ will launch at the very end of a shutdown sequence.

Is there a similar type of thing for scripts that I wish to launch immediately? Without a service file?

What does it mean Ubuntu 18.04 will "support colored emojis"?

Oracle's own documentation about rpcgen states that it has an -A flag which turns on MT auto mode in the generated code.

But on Ubuntu 16.04 LTS, rpcgen does not appear to have this option.

Does anybody know where to find a version for Linux which has this?
