How to disable Ubuntu’s Guest Session

Guest Session - which anyone can log into to the desktop through Guest session – no password required. If you'd restrict access to your computer,

Ubuntu doesn’t expose an easy option to disable this feature. If you poke around the User Accounts configuration tool, where you might expect to find such an option, you won’t find one. To disable it, we’ll have to edit lightdm.conf, which controls the LightDM display manager (login screen)’s settings.

Open LightDM’s configuration file in a text editor through entering the following commands in Terminal (Ctrl+Alt+T),

sudo gksu gedit /etc/lightdm/lightdm.conf

You’ll be prompted to enter your password. After you do, it shows contents of the file.

[SeatDefaults]
user-session=ubuntu
greeter-session=unity-greeter

if it is not shows just copy and paste it.

after that add the following line to the end of the file, in the [SeatDefaults] section:

allow-guest=false

Save the file after adding the line.The changes will take effect when you restart your computer.

Ubuntu Domain join problem (pbis) - Error: Received error while querying lwsmd. [code 0x00000002

First create a systemd unit file for this service, and then enable it. The following worked for me on Ubuntu 15.04 (upgraded from 14.04) with PBIS 8.2.2.
Create the file lwsmd.service in /lib/systemd/system like this:

nano /lib/systemd/system/lwsmd.service

Here are the contents (paste this in to the file you created above).

[Unit]
Description=BeyondTrust PBIS Service Manager
After=network.target

[Service]
Type=forking
EnvironmentFile=/opt/pbis/libexec/init-base.sh
ExecStart=/opt/pbis/sbin/lwsmd --start-as-daemon
ExecReload=/opt/pbis/bin/lwsm refresh
ExecStop=/opt/pbis/bin/lwsm shutdown
# We want systemd to give lwsmd some time to finish gracefully, but still want
# it to kill lwsmd after TimeoutStopSec if something went wrong during the
# graceful stop. Normally, Systemd sends SIGTERM signal right after the
# ExecStop, which would kill lwsmd. We are sending useless SIGCONT here to give
# lwsmd time to finish.
KillSignal=SIGCONT
PrivateTmp=true


[Install]
WantedBy=multi-user.target nss-lookup.target

Once this is done, make a symlink to this file in /etc/systemd/system:

cd /etc/systemd/system
ln -s /lib/systemd/system/lwsmd.service

At this point you should be able to type:

service lwsmd status

and see that the service exists and is enabled.
Then typing:

service lwsmd start

should start it up and have pbis working as expected.
Now to make it work at boot time. Enable the service with this command:

systemctl enable lwsmd.service

It should give some feedback about creating some symlinks.

Then reboot your computer and all should be working.

Installing fonts in Ubuntu & Lubuntu

Press Alt-F2 and type the following:

Code:

gksu pcmanfm /usr/share/fonts/truetype/

which will open a file manager in /usr/share/fonts/truetype/. Be careful, you're root in the file manager and therefore can delete anything.

Then just drag and drop your ttf(s) into that folder. Close your file manager to exit the root session.

Then open a terminal and run:

Code:

sudo fc-cache -f -v

to update the font cache.

How to use Indian Rupee currency symbol in keyboard

Its been quite a while that, the INR or Indian Rupee Currency Symbol was introduced. Earlier there were some ad-hoc solutions released by a 3rd party – like a Rupee symbol Font was released which had to be installed on the system, to view the symbol. Later Microsoft came up with an update for the same, which enables one to type it using the keyboard shortcut. This update too was released a long time back. But even now many people ask about the official method for typing the INR symbol in Windows. Let us see how to type the INR symbol using the Keyboard shortcut for Windows 7 and Windows 8.

Indian Rupee Currency Symbol download

First of all get this update -KB2496898 from Microsoft. Download the update based on your version of Windows. This update requires validation and will validate before downloading.

Using Indian Rupee Currency Symbol in Windows 7

Install this update. The system will require a restart after the install. Once you have installed this, now go to Control Panel > Region and Language > Keyboards and languages tab . Click on ‘Change Keyboards…’ and under ‘General’ tab , click on ‘Add…’ and tick India under English (India ), you can also find this under English (United States) Keyboards.

Once done, you can see it listed under Installed Services. And also you can see it in the system tray.

Now open the document where you want to type the symbol, be it the Word doc or notepad or any other. From the system tray, select English (India). Now use the keys Ctrl+Alt+4 shortcut to type the symbol. On some new keyboards, they have the Rupee symbol printed on the key, just like $. Else in earlier keyboards, look for the key which has $ & 4 on it. I noticed that in some applications such as while typing in Windows Live Writer, I had to use the Ctrl+Alt keys present on the right side of the space bar. It however worked for both sides, when using in Word or Notepad. So this is how the Indian Rupee Currency Symbol is typed in Windows 7.
