Before login screen following messages are displayed:

  1. > 3.786240] pci 0000:00:01.0: ASPM: Could not configure common clock
  2. > nouveau 0000:01:00.0: volt: Type mismatch between the voltage table type and the GPIO table. Fallback to GPIO mode

then the login screen blinks so fast, that I can't even type one character of my password. First message was there from the begining and the second appeared after last dnf update. I also have windows 10 on this laptop (systems are on separate drives). I tried running it on charger and on battery and nothing changed. Also the live version from the usb works fine. I am new to linux and this forum, sorry for my english. Is there any solution to this? (fedora 25 kde)

sounds like a hardware issue, might be detecting something in linux that does not exist in windows. see if the windows will boot, and run diagnostics on the laptop.can you Ctrl-Alt-F2 to login as root from tty? if so, dmesg or jounalctl may yield some ideas also.

I used usb with fedora workstation. Can I post dmesg somehow? It found errors with pcie aspm and conflicts with OpRegion, "If an ACPI driver is avaible for this device, you should use it instead of the native driver", "Can't disable ASPM, OS doesn't have ASPM control","_SB.PCI0.PEGP.DGFX._DSM: Argument #4 type mismatch - Found [Buffer], ACPI requires [Package] (20160422/nsarguments-95)" and some more. As for the second error it is longer: "nouveau 0000:01:00.0: volt: Type mismatch between the voltage table type and the GPIO table. Fallback to GPIO mode. "

Does your laptop have two video cards? nouveau comes up if fedora sees an nvidia card in your system. Try disabling one of the video cards, and see if that helps. do that in the bios settings of the laptop, and see if fedora loads properly.

I am having same situation and this issues happen to appear after last software update, couple hours ago. So, I don't think this is hardware issue! Is out there any solution yet?
