Hi Christopher, I am sorry for the delay, seems like I did not read my email for over two weeks...
I have just tested with "Ubuntu 16.10 "Yakkety Yak" - Alpha amd64 (20161008)". No changes and exactly the same dialogs as described in the original report. I have also updated the desktop to 16.10 (alpha), no improvement either. Let me know how how can I help further. This regression is really annoying... I have to go through grub and BIOS settings each time I am taking the notebook off the docking station. As a workaround I had to disable optimus in BIOS. That also requires putting the following line into /etc/default/grub GRUB_CMDLINE_LINUX_DEFAULT="thinkpad-acpi.brightness_enable=1 acpi_backlight=vendor" Otherwise the machine hangs at boot in kernel. These kernel parameters need to be removed each time I switch BIOS to internal graphics in order to get reasonable battery life. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1556459 Title: [Lenovo ThinkPad W530] Regression: cannot set up 3 display configuration any more (Optimus) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1556459/+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
