I am using HP G62 laptop and it has intel HD graphics. Screen resolution in ubuntu OS is fixed at 1024 x 768. Plz tell me how to change the screen resolution. Apparently there is no option once I goes to system settings/ display
You can use
xrandr -q to see what resolutions are available for your display
From the manpage
Xrandr is used to set the size, orientation and/or reflection of the outputs for a screen. It can also set the screen size.
To change the screen resolution to 1024 by 768, you would type:
xrandr -s 1024x768
Just use that to change it to the size you want.
$ xrandr --output VGA1 --mode 1024x768 --rate 60 $ xrandr --output LVDS --mode 1024x768 --rate 75 $ xrandr --output LVDS --mode 1024x768 --rate 75
