I just installed Ubuntu 14.04 LTS on my very very old notebook (for learning purposes). The installation was successful, but unfortunately I can not change my display resolution. It stucks at 800x600. This makes it very hard to work. My Notebook is a Fujitsu Siemens ESPRIMO Mobile V5535. I used Google, but I am a beginner in Ubuntu/Linux and did not understand anything. I even do not know the commands for the terminal in Ubuntu , so thats why I wrote my problem here. Hope I get some help ! Thanks in anticipation.
