nellazzo Posted June 11, 2016 Share Posted June 11, 2016 Good Morning! I'm having a little trouble with some USB devices, causing several boot loops. 1st boot: I turn on the trackpad during boot process, but a few seconds later, the monitor turns off. 2nd boot: I plug the webcam in, before booting, but the monitor turns off one more time. 3rd boot: I plug the webcam out and the system boots up properly. (sometimes I have to disable graphics "nv_disable=1" in order to boot) I don't know why some USB devices (webcam, trackpad, ext. HDD too) do prevent system from booting, and other USB don't (printer, bluetooth, UPS). Thank you in advance!
