I have downloaded and installed trusty 64 daily build (2013-01-07) on a real partition on the Toshiba Tecra M10 machine used to originally report this problem (so no variable to it being a VM or running from a LiveCD).
When connecting an external monitor via VGA (after machine already running), "Displays" in System Settings now shows proper monitor identification, with the option to set correct resolution. From "Displays" it appears as if the monitor is "Active". However, no signal is detected by the external monitor, and it is "black". If I then restart (so machine boots with the monitor already connected), then all works as expected. Resolution is correct, and both the laptop display and the external monitor are "active". So, the external monitor seems to be identified corrrectly, but when "hot plugged" no signal is sent to the external monitor until a reboot. So, this main component of the original bug report remains unsolved. Please let me know what tests I can perform to provide any more information. ** Summary changed: - [expected] VGA monitor only gets signal on boot (no “hot plugging”, no EDID) + [expected] VGA monitor only gets signal on boot (no signal when “hot plugging”) ** Summary changed: - [expected] VGA monitor only gets signal on boot (no signal when “hot plugging”) + VGA monitor only gets signal on boot (no signal when “hot plugging”) -- 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/979748 Title: VGA monitor only gets signal on boot (no signal when “hot plugging”) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/979748/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : [email protected] Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
