It could be a bug in Emacs? Indeed! It's all "--scale" parameter fault. xrandr's stretch transformation rule was causing that trouble. Really it isn't a Emacs bug. I just replaced that call to xrandr with the following: xrandr --output LVDS1 --off --output VGA1 --mode 1280x1024 Now I'm using a native resolution and disabling the LVDS screen that I don't need at home. That way, I also won the benefit to improve my resolution. It's perfect. My Emacs on a big screen, big resolution, full speed and full screen (without borders, title bar, scroll bar, menu bar and tool bar). It isn't the heaven? -- Bruno Félix Rezende Ribeiro (oitofelix) Ps: Please, let me know my english errors
