Xorg's been around since 2004, and udev since 2003, so it's possible |
| 17 |
that it's depended on udev for displays. |

It seems unlikely, though; I remember XFree86 4.x having EDID support, |
| 20 |
just prior to people migrating over to Xorg. It was a royal pain, |
| 21 |
actually; my Thinkpad 760XL's LVDA (I think it was LVDA. It wasn't a |
| 22 |
common laptop video connection yet) display didn't support EDID, and I |
| 23 |
never did manage to get any version of XFree86 newer than 3.3.6 working |
| 24 |
on it. |

Point is, Xorg autoconfiguration has worked find for *most* setups for |
| 27 |
almost a decade. At the very least, it's worked fine since the first |
| 28 |
graphical Knoppix and Ubuntu live CDs. |
