I'm not sure if it is related with this. I got a Laptop with amd graphics, Radeon HD 4200 and a discrete Radeon HD 5650 (both mobility).
Lightdm does not load with the default configuration (with discrete graphics ON) but it start with the integrated graphics. I have switcheroo configured to turn off de discrete graphics in rc.local so when it boots it does not load Lightdm because rc.local goes after lightdm load, so I have to enter start lightdm in a tty in order to load it. If I try to load manually lightdm with the discrete graphic card, it does no load at all. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1119209 Title: Lightdm does not start on a netboot of Kubuntu 13.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lightdm/+bug/1119209/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
