XFCE4. It’s everyone’s favorite lightweight desktop environment. This desktop environment has been around for quite a while. For much of the time that this desktop has been around, it hasn’t exactly looked the greatest. The default look for XFCE is frankly not that great.

Since the XFCE Desktop is in dire need of a facelift, we decided to go out and find nine really great themes for XFCE4. Check them out below!

Note: the instructions to install each one of these themes are located on the page in which you downloaded them from.

Run the tvservice command to output the result to a file.

$ tvservice -d edid.dat
Written 256 bytes to edid.dat

Pipe the file to edidparser to generate a readable text file.

$ edidparser edid.dat > edid.txt

Grep the desired resolution to check if it is available. For example if you are checking for 1080p resolution

$ cat edid.txt | grep 1080p
  HDMI:EDID found preferred CEA detail timing format: 1920x1080p @ 60 Hz (16)
  HDMI:EDID found CEA detail timing format: 1920x1080p @ 50 Hz (31)
  HDMI:EDID found CEA format: code 31, 1920x1080p @ 50Hz 
  HDMI:EDID found CEA format: code 16, 1920x1080p @ 60Hz

  HDMI:EDID found CEA format: code 34, 1920x1080p @ 30Hz 
  HDMI:EDID best score mode is now CEA (16) 1920x1080p @ 60 Hz with pixel clock 148 MHz (score 5398248)
  HDMI:EDID CEA mode (31) 1920x1080p @ 50 Hz with pixel clock 148 MHz has a score of 4232360

  HDMI:EDID CEA mode (34) 1920x1080p @ 30 Hz with pixel clock 74 MHz has a score of 149416
  HDMI:EDID preferred mode remained as CEA (16) 1920x1080p @ 60 Hz with pixel clock 148 MHz

  HDMI:EDID best score mode is now CEA (16) 1920x1080p @ 60 Hz with pixel clock 148 MHz (score 5398248)

"CEA" corresponds to hdmi_group=1
"DMT" corresponds to hdmi_group=2
The value inside () corresponds to hdmi_mode.
From the above result:
hdmi_group=1
hdmi_mode=16

Take a backup of /boot/config.txt

sudo cp /boot/config.txt /boot/config.txt.backup

Edit /boot/config.txt

sudo nano /boot/config.txt

Uncomment hdmi_group and hdmi_mode and set the right values

hdmi_group=1
hdmi_mode=16 

Save and exit; Ctrl+X followed by Y to save Reboot

$ sudo reboot

How to Create a New User

Let’s start by making a new user within the MySQL shell:

CREATE USER 'newuser'@'localhost' IDENTIFIED BY 'password';

The first thing to do is to provide the user with access to the information they will need.

GRANT ALL PRIVILEGES ON * . * TO 'newuser'@'localhost';

Once you have finalized the permissions that you want to set up for your new users, always be sure to reload all the privileges.

FLUSH PRIVILEGES;
