Abhimanyu's questions

I've installed Ubuntu 21.04. I've followed a few AskUbuntu guides to no avail. My monitor is connected with an HDMI via an AMD RX 580 (Ellesmere) video card.

I do not have any proprietary drivers installed. As it so happens, official amdgpu-install drivers or amdgpu-pro drivers aren't supported in 21.04. In Ubuntu Software as well I see no drivers for my video card.

lspci Displays two audio devices:

• Advanced Micro Devices, Inc. [AMD/ATI] Ellesmere HDMI Audio [Radeon RX 470/480 / 570/580/590]
• Advanced Micro Devices, Inc. [AMD] Family 17h (Models 00h-0fh) HD Audio Controller

In Settings > Sound > Output Device, there's only S/PDIF - Family 17h.

I've tried pulseaudio -k and rebooting.

I've installed Pulse Audio Volume Control (pavucontrol). Pulse Audio > Configuration > Ellesmere HDMI Audio > Profile displays a list of 18 digital stereo and digital surround HDMI outputs. ALL of these profits have (unplugged) (unavailable) in the end, and none of them are able to bring out any audio.

Below is my alsamixer screenshot which I don't understand - is something muted here? I cannot change the values of the "00" either by + or by the up arrow.

I'd like to change the app of the apps on my dock. For example, I'd like to change the Firefox icon to a picture of Kyuubi from Naruto.

My C drive has 100 GB space 50% of which is used. I have four different drives. (One physical HDD worth 1TB). Can I shrink A drive which is 263 GB and take out 30 GB space from it for /home and swap? Or do I have to use the same drive where Windows is installed?

I have the .iso image of Ubuntu 15.10 that a friend gave to me. I have a pre-installed Windows 10. When I mount the image and run wubi.exe, it gives the following error:

Wubi does not currently support EFI.

Please tell me how to install (dual-boot) Ubuntu (with Windows). My FastBoot service is off and Windows is installed in UEFI mode.

I was running localhost (Apache 2.4.6) but only the index.php was openable in the web browser. The subdirectories were returning 403 Forbidden error.

Now, I added the permissions according to this answer. For reference, these were the permissions:

sudo adduser <username> www-data
sudo chown -R www-data:www-data /var/www
sudo chmod -R g+rw /var/www

Accordingly, the folder in which I placed all the content of the website became owned by www-data group. And although I've added myself to the group, I cannot open the folder!

(But the subdirectories have become accessible from the web browser.)

I used to have a password prompt but then I, from somewhere in User Accounts, unchecked "Require a password for login." Now, I want Ubuntu to prompt for a password again at login screen, mainly because I have to manually unlock the login keyring whenever I access Dash or other services, which is a pain at best.

I also searched another question, namely How do I get Ubuntu to ask me for a password at login again?. It was of no help because the OP's question is "I have a password but Ubuntu doesn't ask for it."

Also, the two answers provided there don't solve my problem at all. They discuss completely other things.

Is there no simple mechanism? Because intuitively, if there's a checkbox option to bypass password requirement, there should be an equally hassle-free facility to again require the password.

Ubuntu asks for installing various websites' webapp versions by prompting when I open the particular website. As of now, I've installed WordPress, Facebook Messenger, and Reddit. But I don't see any use of them.

I read a post on Canonical regarding this, and it seemed pretty cool. Notify OSD, native HUD and other generic Ubuntu-specific frameworks are promised to be fully exploited with these integrations, but in practice, it seems just talk and no action.

For example, when I search Facebook in Dash, and click on the webapp Facebook Messenger, it just kicks the browser and opens a new window with facebook.com (even if another window is already open).

All that seems to be working is some FM website that is of no use for me.

I want to know what are benefits of these webapps integration and how do I use the webapps I've installed (let's say the Facebook one).

How do I open an application by a custom keyboard shortcut, like Ctrl+M for opening System Monitor?

I have collected several network connections over time. When I go to Network menu in topbar, and to Edit, the Network Connections dialog shows just one out of three connections. The other two are not modem connections. One is mobile connection and another a tablet connection. Here are the screenshots:

The Network menu:

The connections I want to remove are: "2690 Network" (a Nokia 2690 was once connected for internet) and the "Abhimanyu Network" (when I connected my tablet for internet).

None of these are VPN connections.

If these cannot be removed I want to know whether there's a file that includes data on the connections which I can manipulate to achieve the same effect.

I've picked Inkscape as a replacement of CorelDRAW on my Windows. It's free, so of course there have to be a few backdrops in face of its mighty ability to create perfect XML code for images. However, suppose I want to create a 10-paged documentary on Indian politics. Or anything. Now, how do I do it?

Making a folder and saving each page separately as an .svg file would be messy. So my question is this:

How can I, given that I can in the first place, make a multi-paged document with Inkscape? Even if the answer is "No, you can't," please say so in an answer.

Any application which is not locked in the Launcher can be opened via searching for it. But how do I open an application without the help of the keyboard? That is, without typing in the search field.

Is there no way whatsoever in the entire of Ubuntu operating system to open an app with only the mouse (or any other non-keyboard device for that matter)?

There has to be something like a response-accessibly central menu or something.

I want the menu buttons (close, minimise, and restore/maximise) to be bigger so that they're more visible and the clickable area is bigger too.

If that includes increasing the size of the entire menu bar itself, then I'm up for it.

In Linux operating systems, drives remain unmounted until you open/mount them. As a result, any file residing in an unmounted drive cannot be accessed, like say, from your Firefox history or when you open a saved document from somewhere.

My intuition tells me that there must be some benefit of this feature. What is it?

The notification blip that usually comes on top-right and becomes slightly transparent on hover gets its colour from the background wallpaper, but can I edit it with more options? if yes, then how?

Problem

I have a custom wallpaper as my desktop background, but it doesn't show up on the login screen and the default Ubuntu Unity "greeter" is shown.

Past Cases

In the past, they used to show up on the login screen too. For example, my very first wallpaper was of Elsa from Frozen, and then something else from an anime Bleach. They showed up when I booted the PC and stayed there as I entered the password.

Clarifications

I haven't done any major changes to my system. It's Ubuntu 13.10 (don't give me that support has ended thing, it's merely a technical problem that can be solved). I also tried putting that picture in the Wallpapers directory (Home/Pictures/Wallpapers).

Why This is Not a Duplicate

How do I add customized wallpapers so they appear in the dynamic unity greeter? is about adding an image to the default directory so that they can be changed via Right Click>Change Desktop.

How to change login wallpaper? is about having a separate image for background and another for the login screen.

Gradients backgrounds gives default wallpaper on login screen. is about another default wallpaper and it not showing, instead having the default wallpaper.

Desktop Background doesn't show up on logon screen [duplicate] is a duplicate that leads to the first question I mentioned here.

And they're all I could find in the search.

Hi. I am running Ubuntu 13.10.

The icons of MOST folders on my drive and desktop are showing like never-before-seen "file" icons. I can click on them and they'll open, and inside any of the folders, the folder icons are the usual ones: the same orange Linux folder icons.

Additional Clarification

For clarification, I removed some applications from my system in the earlier session, which included an application that can change the "folder color." I had changed the folder color of "Japanaddicts" folder to pink, rest all were usual.

Please tell me how to fix this problem. In that application, there was no such disclaimer that something like this can happen.

The .iso file that I can download from Ubuntu's website is 970MB.

How much space will it be if I install through this notification that came? Does an upgrade download less data?

RhythmBox is able to edit most, but I also need to override the default/downloaded image of the album art that's displayed when the song is played.

Please tell how to do so through RhythmBox (though I doubt that can be done).

If that's impossible, please recommend a few music editors/taggers that can get the job done.

Their jobs are pretty much the same right? I want to uninstall useless programs. But I fear I may lose important things. I have GIMP and Inkscape installed though.

I am using Ubuntu 13.10 and a wireless internet from a modem "Reliance Netconnect" for the internet.

I've installed Ubuntu two days back along with my Windows system.

So here's a detailed summary of what happens:

I open my computer, the internet connects after I go to the top-right corner, select the signal logo and click on the "Reliance connection" (the only connection for internet on the PC).

It connects immediately and says "You're registered on the home network." and the internet works fine. However, each time I've opened my computer and connected, there's this problem: it automatically disconnects after a while (which is around 5-10 minutes I think).

Let me rephrase: it connects all fine and then disconnects by itself after a while of usage.

Now comes the main problem. NO MATTER HOW MANY TIMES I TRY TO CONNECT IT THROUGH THE SAME SIGNAL LOGO, IT JUST WON'T CONNECT EVER.

It only works when I open it again later and because now I know that rebooting does the trick (well it merely refreshes everything), I reboot to reconnect to internet.

Now, as anyone would tell you, rebooting is not a viable alternative to reconnecting.

What's surprising is I Googled it and not many people have this problem. On two separate threads, people first asked for full details about their modem and networks, drivers, etc. but weren't able to help at all.

I am writing this long piece because I am using my Windows at the moment. Please help me. I don't want to come back to Windows. Ubuntu is so awesome. Everything else is so attractive and I've set up fine. Just this problem is forcing me to leave Ubuntu - or any Linux for that matter. Please.
