Using Mozilla Firefox 68.0.1 on Ubuntu 19.04 x86_64 on a Dell G3 3579.
Using keyboard layout International (AltGr dead keys). The keyboard works as expected in the terminal or gedit, but for some reason, on Firefox, it doesn't. Pressing AltGr + ' doesn't create a dead key but just produces a '.
I'm trying to format an old external hard drive. It doesn't pop up in gparted.
It does get detected though:
dmesg output:

I read somewhere that I should dd the device with zero's, but that fails as well:
$ sudo dd if=/dev/zero of=/dev/sdb
dd: failed to open '/dev/sdb': No medium found
Is there anything I can try before throwing it out of the window?
Every so often, I try to upload a picture to a website and encounter a message:
Upload failed: the file size can't exceed n MB!
I know that resizing the picture's dimension should get me below n at a certain point, but the process of resizing, saving, checking file size is cumbersome. Furthermore, at times it may be handy to keep the current dimensions.
I'm looking for a way to change a picture's file size, preferably from the terminal. Is there a way to do this?
In the Ubuntu Software Center, there are lots of $0 apps that I can 'purchase': for example:
As these applications are free (as in beer), I wonder how I can install them using apt-get.
I'm interested in reading Python documentation when I'm traveling.
Right now, I'm doing that by entering the command:
$ pydoc2.7 PyQt4.QtGui.QPushButton
Help on class QPushButton in PyQt4.QtGui:
PyQt4.QtGui.QPushButton = class QPushButton(QAbstractButton)
| QPushButton(QWidget parent=None)
| QPushButton(QString, QWidget parent=None)
| QPushButton(QIcon, QString, QWidget parent=None)
|
| Method resolution order:
| QPushButton
| ...
| ...
| ...
I don't really like this way of reading the documentation. I'm interested if there are other applications which let me read Python documentation offline.
I've just installed Steam, and I've noticed that Steam has created a lot of files and directories in my home directory: such as:
linux32resultsteamdeps.txtsteam_install_agreement.txtsteam_latest.debsteam.shubuntu12_32Can I safely remove these files from my home directory? If not, what would you advice to clean up my home directory?
Is there any way to stop Steam from polluting my home directory in the future?
I know that I can run an application in the background by putting an ampersand (&) at the end of the command. For instance:
$ rtorrent &
[1] 4618
starts rtorrent in the background.
I'd like to return to the backgrounded rtorrent to check whether my downloads are completed. How can I do that?
I'm using Lubuntu 12.04, with xfce4-volumed installed, see this question. When I'm changing the volume using FN+Vol-, a nice notification balloon pops up. This is what I want. However, when I try to change the volume 10 seconds later, I first have to click the 'Clear all notifications' button to get further notifications. I want to get rid of this: xfce4-volumed should always be giving notifications, whether or not I've clicked the button.
How can I get this done?
Answers that tell me how to disable the whole envelope thing, or change it by another notification daemon to get this done, are also welcome.
Recently, I've been backing up a lot of my data, and I noticed that I can save files as .gz or .tar.gz, or .7z and .tar.7z, etcetera. What are the differences between the normal one and the .tar.* variant? Which one of them is adviced when making backups?
When I install Ubuntu, the first thing I usually do is remove some programs and install some others. To get that done, I enter the following in a terminal:
sudo apt-get remove applicationA applicationB applicationC && sudo apt-get install applicationX applicationY applicationZ.
This works nicely, but the problem is that I have to confirm twice: first I have to confirm the removal of the applications, and after some time I have to confirm the installation of the others. It would be great if I only had to confirm once, because I wouldn't have to come back to the computer in the meantime. Is there any command to get that done?
Please note that I'm not looking for workarounds in e.g. Synaptic Package Manager. I want to do this from the command line.
Thanks.
I find the Messaging Tray (the bottom bar) in GNOME Shell rather inconvenient. I'm looking for a way to disable it. KRSNA 2 ZED seems to have written an extension for doing just that, but I don't know how to install it. Any help would be appreciated.
I'm using Ubuntu 11.10 32-bit.
I like the behavior of Gnome-Shell's Alt-Tab window changer, but there is a slight delay when pressing Alt + Tab, which bothers me. Is there any way to make it pop up immediately, or at least, decrease the delay?
I've got a directory shared on my network, using Samba. People on the netwerk use this Samba share to download files from my share to their computers. I'm interested in what files are downloaded most, and by which users they are downloaded. I'd like to see this in real time, if possible. Is there a program that allows me to do this? If yes, how can I use it?
I'm using Ubuntu 11.10.
Whenever I search for a program in Gnome Shell's search panel, some contacts from Pidgin will appear. E.g. when I search for Chromium, by typing chr, Chris Andersen will appear. I don't want this to happen. Is it possible to disable this function?
I'm on Ubuntu 11.10, and I want to share a folder on an automounted NTFS partition (/dev/sda4) over the network. The purpose of this network is to share files between computers, it contains mostly Windows computers. I use this /dev/sda4 partition both from Windows 7 and Ubuntu. Using Nautilus, I right-click the directory, then I click 'Sharing Options', then I mark the three checkboxes. When I try to apply the settings though, it says 'Couldn't change the rights of the folder "foldername"'.
I've put the output of sudo blkid and cat /etc/fstab below.

How can I share this folder?
I have Lubuntu 11.10 installed on /dev/sda3, and Xubuntu 11.10 on /dev/sda5. A while ago, while being on Lubuntu, I made a mistake somewhere in creating a Live USB: by mistake, I installed a Live USB bootloader into /dev/sda3. This didn't result in any problem at that time.
Today, I updated the kernel. I had to restart Lubuntu. In Grub, Lubuntu suddenly didn't appear anymore, and I booted automatically in Xubuntu. I tried to run update-grub and tried to use grub-customizer to get Lubuntu back in Grub, but this didn't work. I ran os-prober, but it doesn't show me Lubuntu.
Then, I tried to add a new entry to /etc/grub.d/ on /dev/sda5 called 12_lubuntu. It contained the following:
#!/bin/sh -e
echo "Lubuntu"
cat << EOF
menuentry "Lubuntu" {
set root=(hd0,3)
linux /boot/vmlinuz
initrd /boot/initrd.img
}
EOF
After doing that, I ran update-grub and with grub-customizer, I wrote the Grub-configuration to MBR, that is: /dev/sda.
Suddenly, Lubuntu appeared in Grub. I tried to launch it, but when doing this, the following messages appeared:
Error: File not found
Error: You need to load the kernel first
The output of ls -all in /dev/sda3 is as follows:
gijs@Gijs-PC:/media/9c715f68-f083-46ab-9d55-6139556f31d4$ ls -all

How can I make Grub start Lubuntu again?
In Lubuntu, there's no 'Add New Program...' button in Desktop Session Settings. Is there an easy way to add new autostart programs in Lubuntu?
I'm using Lubuntu 11.10. That's great, but sometimes I miss Ubuntu's eye-candy. I can install Ubuntu 'as a layer' on Lubuntu, so I'll be able to choose the 'layer' in the login screen. But doing this will leave typical Ubuntu stuff on my Lubuntu install as well, which bothers me: I want to keep the Lubuntu install clean.
I've booted Ubuntu 11.10 from a live USB, and then tried to install it 'alongside' Lubuntu (so I could choose the right operating system in GRUB). But this option doesn't show up. I'm not an expert at using the advanced installing mode, but this could be the key to get this done.
So, my question is: How can I install Ubuntu alongside Lubuntu, without changing the Lubuntu setup?
I'm looking for a lightweight way to snap windows in Lubuntu. It's possible to install compiz, but doing so will make the system far less lightweight. Are there any alternatives or workarounds?
I'm looking for a lightweight way to mount iso's on my fresh-install of Lubuntu 11.10. Furius Iso Mount has been my favourite on Ubuntu, but it installs too many extra stuff on Lubuntu, like Brasero. What would be the best choice?
