just installed Ubuntu 11.04, but cannot get my external monitor to work in "same image in all monitors" mode. Its only possible to choose same resolution for the external monitor as for the laptop. External is 1920*1080, laptop 1200*800px When mirror is selected, ubuntu identifies BOTH monitors as "laptop" and BOTH monitored displays 1200*800px. Any help much appreciated ... |

Do you have a Nvidia graphic-card? There is a special tool for Nvidia called disper. It should work with other cards too. You can install disper from ppa:disper-dev/ppa Then type This should clone the desktops on internal an external monitor. See here on launchpad. |

yeah I've been trying to get monitors to work correctly in any distro of linux since Softlanding (up hill both ways, get off my lawn). You can find many of my rants over the last 15 years or so on usenet, blogs, ubuntu absolute beginner forusm, every time a new distro comes out and I try and get it, and even today the monitor handling is worse than Windows 95 was back then. The closest I ever came was using xrandr in 10.04, so that's my answer and suggestion - just read as much as you can find about xrandr. IIRC I was able to rotate a display and had an immediate gnugasm, but then the other monitors stopped working right - what gets real fun is if you want to do something seemingly easier than a Thesis about hardware drivers in FOSS like just changing which port displays are plugged into. Just don't. If you have a working set up, this will dick things up into perpetuity. Just give in, be happy with just the one monitor. |

Even I Have Similar kind off problem. I have installed it in an ATOM Box and connected to my monitors VGA port and my monitor is also connected to another machine through DVI port. When I am trying to detect the monitor from my ATOM Box, but it shows as mirror It cannot detect the Monitor and resolution is limited to 1200*800 though my monitor is 1080p full HD. |
