Talk:Installing Ubuntu 5.10 on a ThinkPad R50e

dual head with Xinerama on R50e

I managed to have Ubuntu with dual screen & xinerama work properly after a few attempts. However, the solution is not very polished yet and I need to swap my xorg.confs around (with a script) and restart the X server (logout, ctrl-alt-backspace) each time I go from single screen to dual screen or the opposite. Which is why I don't post on the main R50e page.

Here is my dual screen xorg.conf for those interested, used on Dapper 6.06 TLS. I plug the external screen before bootup, this might have an impact on wether it works.
