Hello Daniel, just to close my request: The latest git pull from Linus' tree fixed my issue. vmlinuz-3.16.0-rc2-00211-gd7933ab (26.6. 21:19) was bad vmlinuz-3.16.0-rc2-00319-g3e7b256 (28.6. 09:23) works again There are two pulls with 'drm-fixes' and 'x86/urgent' in this area. Don't know what it was in detail - but it's fixed now (lightdm/xfce4 runs).
