Thank you for reporting this problem. Could you try and run this command in a terminal before you plug in the external monitor and upload the resulting file (udevadm.log) here (after you reboot)?
udevadm monitor --property > ~/udevadm.log Hopefully, there will be some clue to what is going on in this file. -- [arrandale] Dell Latitude E6510 unable to use second external vga monitor https://bugs.launchpad.net/bugs/596082 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
