window size
 

Some windows are way too big to fit my screen and have to manually drag them to see it all. How do I fix it? My screen resolution is 800x600.

1) if you're using KDE or Gnome, you can right-click and then go Configure Desktop. This will let you play around with the screen resolution

2) You can use the controls on your monitor to make the visible screen size biiger or smaller, or try darg it more towards the middle of the screen, etc. Yu can pay around with these as much as you like, although messing with Mouirve settings can damage your monitor.

3) If you have an nvidia card, try downloading the latest driver. This will autoconfigure itself, and perform varios checks.
