HRZ, I'm not linux expert either. Here's a more detailed step for 3 & 4. Step 3 - launch xterminal (it's already installed on N900) - type the following and press enter sudo gainroot - done Step 4 - While you are still in xterminal - type the following and press enter leafpad /etc/mce/mce.ini - the leafpad application will launch. (if installed as per step 2) - you are now seeing the contents of mce.ini file.
