Sometimes on startup, Ubuntu does not recognize my USB Keyboard & Mouse. This problem is frustrating as Windows seems to recognize them.

It took me a while to recognize the root of the problem was with the USB 3.0 ports on the Motherboard. By moving the usb connections to the USB 2.0 ports on the motherboard this problem was solved.

Problem: USB Keyboard and Mouse dont work on boot up.
Solution: Move the connectors to the devices from a standard USB 3.0 port to standard USB 2.0 port(check with your motherboard manual for specifics)

Kate: Not allowing to Edit Specific Files – Solution



Recently I encountered an interesting problem with Kate. When ever I opened certain files it opened them in read only mode. The files had the necessary permissions to let me write and I could open them in nano or vim and edit them successfully.

There can be multiple reasons for this happening:

  • File is in use in some program (known to cause problems with Kate)
  • File is a PHP file and being accessed somewhere
  • File has more than 1024 characters in a line. (The limit might vary but after a point the files are opened as read only)

Mplayer without Text

I upgraded my desktop to Kubuntu Karmic 9.10 yesterday and realized an unique problem. There was no text displayed in the OSD(On Screen Display).

Mplayer without Text

If you open the file in command prompt mode you will see the following message:

subtitle font: load_sub_face failed.

The reason for was basically that Mplayer could not find the required font file to display the text. To solve the problem you need to open the .mplayer directory in your home directory. And do one of the two following things:

  1. Copy any font file of your choice to that directory and rename it subfont.ttf (You will find fonts at /usr/share/fonts)
  2. Open the config file in the .mplayer directory and add the following lines:
    font=/usr/share/fonts/truetype/msttcorefonts/Times_New_Roman.ttf
    subfont-text-scale=2.5

Ps: You can replace the link to your favourite font after the font= command.  Also using Method 2 will let you even set the size of the font
