Howdy, I just realized that I talked several pages long and I never |
| 15 |
thought to make 3 very important remarks, 1) my experience with |
| 16 |
multimonitor was in Ubuntu 2) I'm no longer in a situation where I did |
| 17 |
presentations all the time any more, 3) the Ubuntu have been reinstalled |
| 18 |
with the current Gentoo |

I don't remember their exact version, although it should be last year's |
| 27 |
latest in Ubuntu repository. I never switched to Intrepid because I |
| 28 |
moved to Gentoo. |

Yeah. I've just replied on the other post that xrandr only works well in |
| 37 |
a single monitor on my specific hardware configuration. |

I tried a LOT of thing and many of them are not nice. I think virtual |
| 51 |
desktop size was one of them. The result, as I remember, was a bit odd, |
| 52 |
as setting the desktop larger than the monitor resolution gives panning |
| 53 |
and not dual monitor. (or was that the effect of another setting, let me |
| 54 |
check my memory first...) |

It was nvidia binary driver. Not sure of the exact version number as it |
| 64 |
gets through several updates. It should be last year's latest |
| 65 |
nvidia-glx-new in Ubuntu. |
