I'm beginning to think this is a driver issue. I have a builtin "Kaveri" amd gpu, and pci Radeon HD 4850. I usually have the 4850 as my primary card/monitor setup. However, since upgrading to Ubuntu 17.04, once lightdm is started, only the monitor on the Kaveri works.
I dropped to VT1, and ran `X -configure` after shutting lightdm down, and received an error: amdgpu_device_initialize: DRM version is 2.49.0 but this driver is only compatible with 3.x.x -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1692437 Title: Monitors on second GPU not working after upgrade to zesty To manage notifications about this bug go to: https://bugs.launchpad.net/lightdm/+bug/1692437/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
