Some weeks ago I started having some issues with the original 64-bit Windows 7 Home Premium installation on my Dell XPS 15 notebook. After completely loosing communication capabilities (which I managed to restore, but with some pending issues) some days ago, I decided it was time to get back to Linux. I decided to install Linux Mint with XFCE. After proceeding with a dual boot installation, I figured out everything was fine expect for a very tiny detail: I couldn’t get a cedilla from the standard key sequence I was used to ( ‘ + C ). Instead of a cedilla, I got an inverted cedilla (or a C with an accent, whatever) ć.
In my case, that was because I wanted to keep the system using English language as locale (EN_US) but still wanted to be able to use my US-international keyboard to write Portuguese texts.
After researching in the Internet, I got some interesting solutions and the best one was editing /etc/environment and adding a line to change the input method (IM) to one with cedilla support. All you need to do is to append the following line to the environment file: export GTK_IM_MODULE=cedilla
In order to edit the file you can use any text editor, such as vi or xed which is part o Mint, so, just type:
sudo xed /etc/environment
And in the editor append the following line:
Then restart your GUI or the computer and watch the possibility of typing ç with no effort at all!
