After screwing around with things for a few months I've realized my system's behavior is stranger than it originally appeared, and perhaps my problem is a different bug from what's been reported here. Still running the same system from my prior post (Ubuntu 11.10, Toshiba M700 Laptop, Docking Station, Intel GM965/GL960 Integrated Graphics Controller) I've found that I can reliably get dual montors to work with the following procedure:
- Boot with only the VGA monitor attached to the docking station (VGA works normally with LVDS1) - After boot is complete, connect DVI monitor (output switches to DVI, VGA goes blank) - Using arandr disable LVDS1 output (output switches back to VGA) - Using arandr enable DVI output (dual displays active) - To make DVI primary, disable/enable VGA output If I boot with the DVI monitor connected I've found no way to get the VGA output to work, even if it is detected by the OS. I don't know how to debug this in any reasonable fashion. If this is interesting to anyone that can walk me through the relevant data collection steps I'd be glad to get what information I can. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/763688 Title: [915GM] S-video output doesn't work in Natty (i386) To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/763688/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
