Helpful hints for finding large files and folders

• Find large files (10MB+):
  
  sudo find / -type f -size +10000k -exec ls -lh {} \; | awk '{ print $NF ": " $5 }'

• Find the largest folders (in current working directory):
  
  sudo du -hsx * | sort -rh | head -10

# ps x |grep -v grep |grep -c "processname"

#dd if=/dev/sdX of=/dev/sdY bs=64K conv=noerror,sync

Here, sdX is the source disk, while sdY is the destination. The numerical value 64K, corresponds to the block size command, bs. The default value is 512 bytes, which is very small, so it’s best to include 64K or the larger 128K as a condition. However: while a larger block size makes transfer quicker, a smaller block size makes the transfer more reliable.

Creating directory with space in name

Try to reconfigure lightdm, it may fix your issue

• Open terminal(CTRL+ALT+T) and execute following command:

  sudo dpkg-reconfigre lightdm
  

• Then chose lightdm from the list.

• Restart your system:

  sudo reboot now
  

It may fix your issue. If doesn't fix then follow 2nd Method.

Method 2:

Installing a new display manager can fix your problem. Steps to install GDM(a display manager much like lightdm):

• Open terminal(CTRL+ALT+T) and execute following commands:

  sudo apt-get install gdm
  sudo dpkg-reconfigure lightdm
  

  then chose gdm from the list. And restart your system:

  sudo reboot now
  

sudo apt-get install lightdm-gtk-greeter

or sudo apt-get install lightdm-kde-greeter

Personally , I keep both of these on my machine.

Next, you need to tell lightdm desktop manager which greeter to choose on boot. To do that, type

sudo nano /etc/lightdm/lightdm.conf

sudo apt-get purge libappstream3      OF   2. sudo apt install libappstream3     OF

3.   sudo apt-get purge libappstream2 && rm /etc/apt/apt.conf.d/50appstream









INSTALLATIE VAN WPS-OFFICE, O.A. HET MOOIE PROGRAMMA WPS-IMPRESS (powerpoint-alternatief)                 32 bit:   command-line installatie:




													  64 bit:   command-line installatie:	

First, remove any existing installs of ir-keytable and/or lirc – from Linux command line do:

sudo apt purge ir-keytable lirc

Also, if you have added any other software in an attempt to get the remote to work, you probably should remove that as well.

Next, we’re going to temporarily edit /etc/apt/sources.list – we will use nano, but feel free to use vi or vim if that’s your thing:

sudo nano /etc/apt/sources.list

Add this line at the bottom of the /etc/apt/sources.list file:

deb http://ca.archive.ubuntu.com/ubuntu/ xenial universe

Use Ctrl-X to exit nano; be sure to save the file (unless you made a mistake, then just exit without saving and start over).

Then, from the Linux command line:

sudo apt update
sudo apt install lirc/xenial

You should see it install lirc and a few dependencies.  Somewhere in the process you should see “Setting up lirc (0.9.0-0ubuntu6) …” and also you should get the configuration screen, from which you can pick the type of infrared remote you use (such as “Windows Media Center Transceivers/Remotes (all)”, which is down near the bottom of the list).

After that is finished, do this so Ubuntu won’t try to upgrade lirc to the newer bad version:

sudo apt-mark hold lirc

Now that lirc is installed, you need to go back and remove the line you just added to /etc/apt/sources.list:

sudo nano /etc/apt/sources.list

Scroll down to the bottom of the file and put the cursor at the start of this line and press Ctrl-K to delete it:

deb http://ca.archive.ubuntu.com/ubuntu/ xenial universe

As before use Ctrl-X to exit nano, and be sure to save the file.

Now from the command line you should immediately do this so that your system doesn’t inadvertently try to get any other packages from the xenial universe repository:

sudo apt update

And that’s it!  What we have done here is to temporarily enable the Ubuntu 16.04 (xenial) universe repository, where a copy of lirc 0.9.0 is available, and then we installed it using the apt command.

We do realize that there may be alternative way to do this, such as downloading the lirc package from the xenial repository (the amd64 version is here) and then installing it using dpkg, but we’d be a little concerned that doing it that way either might not bring in the necessary dependencies, or might not show the configuration menu.  But, feel free to try doing it that way if you’re much more conversant with Linux than we are.

We hope this helps others who have struggled to get their infrared remote working with Kodi in Ubuntu 18.04!
