Option 1 is to set it using a configuration file "snippet" in the /usr/local/etc/X11/xorg.conf.d directory, like the traditional xorg.conf: only put section "Screen", subsection "Display", setting "Modes" with the screen size you want. For example, it could look like this: Section "Screen" Identifier "Screen0" Device "Card0" Monitor "Monitor0" DefaultDepth 24 SubSection "Display" Viewport 0 0 Depth 24 Visual "TrueColor" Modes "1920x1080" "1280x800" EndSubSection EndSection You could then probably even use Ctrl+Alt+[+] and Ctrl+Alt+[-] to switch between the two modes (not tested, but old-fashioned X could do that). Option 2 is to use xrandr in ~/.xinitrc with the --size option. > If I connect an external 1920x1080 monitor to the VGA port of the laptop > and press the Fn+F8 (CRT/LCD) hot key at the GELI prompt, the video > signal is sent to the external monitor (laptop screen goes dark).

You can even use xrandr from inside a running X session to change the screen size dynamically. It's also a convenient tool for experiments. (Side note: I set up a Dell Latitude D630 laptop with a screen size of 1280x800 and an external monitor of 1920x1080, but I use Mate on this specific system which offers the native screen size in its configuration program.) -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
