>From Christopher James: that "no screens found" thing is because lightdm starts X before the kernel module has finished initialising.
>From robert_ancell: (I just cut off the necessary quote) <robert_ancell> nah, it needs to ask the kernel generally - and there's a signal for "card ready" that comes via udev I believe <robert_ancell> start on ((filesystem <robert_ancell> and runlevel [!06] <robert_ancell> and started dbus <robert_ancell> and (drm-device-added card0 PRIMARY_DEVICE_FOR_DISPLAY=1 <robert_ancell> or stopped udev-fallback-graphics)) <robert_ancell> or runlevel PREVLEVEL=S) <robert_ancell> is the upstart script /etc/init/lightdm.conf <robert_ancell> it's the drm-device-added card0 PRIMARY_DEVICE_FOR_DISPLAY=1 which is what is waited for - my guess is that driver is not doing that / doing it wrong <robert_ancell> yes, afaik. so the short answer is "it's probably a driver issue". -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/966871 Title: X failed to start, failed to set drm interface version To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/966871/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
