For example, if they are both 1440 x 900 monitors, make sure it is set to that resolution. If your watch a lot of movies it is important to set your Monitors to your lower resolution. It makes life easier if you pop open a terminal and type to open your gui monitor program: I will summarize the points that I think are important and add a few points. This article above will give you some important background information. If you want to have a panning viewport, i.e., a virtual screen that's bigger than your physical screen that moves when you move the mouse to the edge ("zoomed in" view) specify the desired physical resolution with -mode and the virtual screen size with -fb and panning area (typically same as virtual screen size) with -panning. xrandr has a lot more capabilities - see man xrandr for details. Note that changes you make using xrandr only last through the current session. $ xrandr -output LVDS -mode 1024x768 -rate 75 $ xrandr -output VGA1 -mode 1024x768 -rate 60. The refresh rate may also be changed, either at the same time or independently: $ xrandr -output LVDS -mode 1024x768 $ xrandr -output VGA1 -mode 1024x768.You can direct xrandr to set a different resolution like this: LVDS connected 1400x1050+0+0 (normal left inverted right x axis y axis) 286mm x 214mm VGA disconnected (normal left inverted right x axis y axis) Without parameters, xrandr shows you the names of different outputs available on your system (LVDS, VGA-0, etc.) and resolutions available on each: You can either use the Screen Resolution GUI tool to experiment with different resolutions, or the more powerful xrandr command-line tool. If you set a resolution inappropriate for your monitor in the Screen Resolution GUI tool, you can reset it from a terminal by runningÄynamically testing different resolutions Obtaining modelines from Windows program PowerStrip.Goto Ubuntu Menu: System -> Preference -> Display.Use cvt/xrandr tool to add the highest mode the LCD can do.Setting resolution changes in nf - resolution lower than expected.Setting xrandr commands in kdm/gdm startup scripts.Dynamically testing different resolutions.
