Or simply searching the archives of the xorg-driver-ati mailing list, with a Google search like: site:lists.x.org/archives/xorg-driver-ati/ <your search pattern> And just in case someone could use it: I didn't find the following via Google, but in the ati driver sources: It seems it's impossible to have the complete content of the LCD screen mirrored on an external monitor, as long as the LCD is switched on. So I do something like this to get the complete LCD content mirrored to an old VGA: xrandr --output DVI-0 --mode 1280x1024 --rate 60.0 xrandr --output LVDS --off After executing the first line, the LCD content is cloned partially to the VGA, i.e. about 10% of the LCD content is missing on the VGA screen. This is fixed as soon as I switch off the LCD with the 2nd line. _____________________________________ $ xrandr -q Screen 0: minimum 320 x 200, current 1280 x 1024, maximum 2720 x 1024 LVDS connected (normal left inverted right x axis y axis) 1440x960 59.9 + 1280x800 60.0 1280x768 60.0 1024x768 60.0 800x600 60.3 640x480 59.9 DVI-0 connected 1280x1024+0+0 (normal left inverted right x axis y axis) 300mm x 225mm 1280x1024 60.0* 1280x960 59.9 1280x800 60.0 1280x768 60.0 1024x768 85.0 84.9 75.1 70.1 60.0 800x600 84.9 85.1 75.0 60.3 640x480 85.0 84.6 75.0 60.0 59.9 720x400 70.1 S-video disconnected (normal left inverted right x axis y axis) _____________________________________ I'm not sure I understand correctly what the author meant to indicate with the following. At any rate, IIRC, the two-liner above dawned to me after reading this: README.ati, excerpt: ----------------------------- In situations where the driver is to simultaneously display on both a panel and a CRT, the same image will be seen on both. In particular, this means the CRT must be able to synchronise with the timings of the panel's native resolution. This is quite evident when the panel has ``odd-ball'' dimensions, such as 1400x1050, a resolution not commonly possible on CRTs or projection equipment. Also, the display of independent images on the panel and CRT is not currently implemented, and might never be, pending resolution of the previous item. ---------------------------- Caveat: If screen dimming is enabled here, via pbbcmd config onac_timedim 1800 then the screen on the switched off LCD is coming back partially/garbled, as soon as the LCD screen is getting dimmed (after ~ 3 mins. of inactivity ..)
