Hello, I just preupgraded from F10 to F12, and booting goes as far as the Fedora logo (circle with lower tip) filling up with white, then flashing briefly. Then the screen goes and stays blank afterwards, except for a cursor, and it displays if I type somthing. It also seems to shut down orderly when I push the off button (with messages similar to a regular shutdown of a running system, although significantly fewer in number). If I edit away the "quiet" argument before booting, I see a few lines instead. The last of those few lines are (hand-copied, may contain typos): fb0: nouveaufb frame buffer device registered panic notifier [drm] Initialized nouveau 0.0.15 20090420 for 000: 07:00.0 on minor 0 dracut: Starting plymouth demon dracut: Starting plymouth demon usb 2-2: new low speed USB device using uhci_hcd and address 3 The only USB devices I am aware of are mouse and keyboard. I have a wired Internet connection. How do I proceed from here? Thanks!
