I don't know what happened but my laptop's resolution is not stuck in 1024x768 even though the laptop's resolution is 1366x768. Another problem i am facing is that the performance of my PC all of a sudden decreased. The animations that were fluid smooth before now take a very long time. And everything seems slowed down.
Worse thing is that a 4:3 aspect ratio resolution is stretched in a 16:9 widescreen panel hence making everything appear look wider. Please help me as using my laptop is a pain in the A$$ for now.
My "xrandr" output is
And also in the "Monitor Settings" app there are no other resolutions available. The only two options i seem to find are 1024x768 the Auto option. None of which can solve my problem.

Any help would be highly appreciated.
