What step to reproduce could be?! Just installed clean system, root partition was formatted - may be it worked somehow - was far away, but not all the time - grey screen was as well, but after I installed nvidia driver - green dots. Uninstall - green dots. DO not want to reinstall again. Possible uninstall scripts are not clear. Tried to reinstall nouveau - no luck.
