mini's questions

When I press the key 1 on my laptop keyboard, it does not print anything on the screen, but Shift+1 prints !. I have this problem only with just with 1!

1. It doesn't matter which layout is in use, I tried different layouts and still 1 prints nothing.

2. I test the issue on a USB keyabord plugged to my laptop and still can't print it.

My HDD partitions:

• esp --> sda1
• archlinux --> sda2
• swap --> sda3
• sda4 --> would be a place for ubuntu

I'm going to install ubuntu on sda4; currently my boot process is controlled by systemd-boot which is installed in archlinux via bootctl software. It's fine and I'd like to keep it.

By installing Ubuntu it will try to install grub on sda or sdaX. Look at the dropdown menu at this screenshot:

I want to install Ubuntu on sda4 without dealing with grub. Then I will point to Ubuntu vmlinuz file and initrd file by creating a new entry file in archlinux under systemd-boot configuration system.

sudo apt-get autoremove .

What does that dot do?

After upgrading to 14.04, my kernel is not upgraded! it's like before:

Linux Boxi 3.11.0-18-generic #32-Ubuntu SMP Tue Feb 18 21:11:14 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

Here's what I did:

sudo apt-get update
sudo apt-get dist-upgrade
sudo do-release-upgrade
sudo apt-get update
sudo apt-get dist-upgrade

lsb_release -a

vpnbook.com offers a free openVPN service. This is one of their files: http://paste.ubuntu.com/7231382/ with the name vpnbook-uk1-tcp80.ovpn.

I want to convert it to 3 files to be usable in network-manager-openvpn:

I want to create this folder: $HOME/a/b/c/d while $HOME/a has not yet been created! Is it possible with one line in Terminal?

'-ab' option is related to audio quality? how to say ffmpeg to keep the original audio quality during conversion?

How to use VPN just for some part of the system? This means that, for example, Firefox and aria2c will use the vpn and pidgin won't! Is it possible?

In my case, I want to use VPN for whole system except: transmission, apt-get and pidgin or vice versa: Just using vpn for these software: firefox, aria2c, youtube-dl

I've installed Dropbox_2.2.10.tar.gz.

Its installation instruction says: "Download this Python script to control Dropbox from the command line. For easy access, put a symlink to the script anywhere in your PATH"

Where should I put the script to run dropbox like other software which run from the terminal and the Dash?

For example:

00:00:00 to 06:00:00 -> Slitaz
06:00:01 to 13:00:00 -> Ubuntu
13:00:01 to 19:00:00 -> Fedora
19:00:01 to 23:59:59 -> openSUSE

Can grub change default 'entry' automatically?

I want to install workman layout on Ubuntu, I do not know how to do that?!

Workman layout blog: http://www.workmanlayout.com

I'm downloading a file with Transmission. It shows a connection to a web seed. See the below screenshot:

What is that "web seed", shown in the picture (which kind of seeders?)? Is it safe?

I want to turn off monitor on a specific period of time automatically (for example between 07:00 and 11:00). Is there any command to be set in crontab file? Is there any better way?

In summary:

Turning off the monitor at 07:00 automatically.

Turning on the monitor at 11:00 automatically.

• scren-saver & lock screen are disabled!

1. How can I see crontab tasks which are in progress?
2. How can I stop crontab tasks which are in progress, manually?

Is [this] question about see the current running cron processes?

Yes

To kill a process manually one way is to use pkill

I had thought about pkill/killall, but some of my commands in crontab file are respectively! it means that after finishing a command, the next one will be started! for example:

sudo crontab -e
00 10 * * * /usr/bin/wget LINK ; shutdown -h now

So, If I kill wget, the computer will be powered off!!! -> I want to kill a cron task fully, not a part of it!

The next pkill problem: What about scripts? (I've imported some bash scripts to crontab -e) --> sudo pkill ???

I have a USB cooldisk 8.0 GB. it was full of Windows viruses. I tried to delete them under Ubuntu 13.04, but it didn't allow me to delete anything!

I formatted it using 'Disks' to FAT filesystem and overwrite all data by zero. Again, I can't delete anything! I can't change permission of any file!

But, I can do anything by Terminal (CLI). I can create folder by mkdir. I can copy files by cp. etc. I ran sudo chmod 777 -R /media/me/USB/*, but the permission did not change:

I want do all this in Nautilus. It does not allow me to create folder, copy, change permissions in Nautilus (Files).

What's the problem?

(Ubuntu 13.04 with GNOME Shell, upgraded, GNOME version 3.8)

Recently, I upgraded Ubuntu to 13.04. the default desktop is gnome-shell.

Except Nautilus, other software border doesn't disappear when I make them to be maximized. I checked the problem for these software:

• LibreOffice
• Firefox
• Rhythmbox
• thunderbird
• GNOME-Terminal

On the other hand there are three bars on maximized mode:

1. GNOME Shell panel

2. Title-bar for software which contains - + x (minimise, maximise, close) buttons.

3. Software menu-bar

   

   Number "2" is extra. Is a package missing?

   

My 3-year girl loves SuperTux. She can't control the mouse, so the game should run automatically on startup. After the game, the computer should shut down automatically.

However when I put the below command in "crontab -e":

@reboot env DISPLAY=:0.0 /usr/games/supertux2 && echo "PASSWORD" | sudo -S shutdown -h now

The first part runs the game on an old PC at boot time. I expected the second part of the command to turn off the computer when my girl exits the game but it isn't working.

Doesn't the chain-command A && B mean when the A finished, start B?

How can I automate the powering off computer when the game is closed?

I'm going to set up my computer to be turned on at night and it will automatically start downloading. For security reasons, I do not want to set up Ubuntu to automatically login. The problem is the login screen where I need to type the password manually to enter.

When do applications in start up run? From the login screen's appearance or from the desktop veing drawn?

Is the software on this list able to run from the login screen (without the user entering the desktop by password), when they have been placed in startup applications?

LIST: crontab, aria2c, transmission-gtk, shutdown, uGet, xdman

I want to limit transmission to work at 02:00 AM untill 08:00. How?

I have been using gnome-shell for a few months. I was able to configure it using "tweak tool" and "background". Now I've just migrated to Unity, but "Change Desktop Background" (comes from right-click on desktop) launches "System Settings". I'm not able to swap desktop wallpaper or change launcher icons' size, etc. As you can see from this picture, the "Appearance" icon has been removed from "System Settings". What's happened to my Ubuntu?

My OS: Ubuntu 12.10; Unity + gnome-shell; latest updates
