Today when I start up my laptop the resolution have dropped to 1024 x 768. My native resolution is 1280 x 800. I tried searching for solution but it doesn't work. Its quite hard to use it sometimes.

I'm using Acer Aspire 4930 with Mobile Intel® 4 Series Express Chipset Family

This is what I get when I do ddcprobe on terminal

  • My native is 1280x800 but the maximum resolution that I can choose is 1024x768. It also recognizes my graphic card as Intel(r)Cantiga Graphics
