Public bug reported:
Binary package hint: acpi
I came back to my computer while the screensaver was running, moved the
mouse, and was prompted for my password. Then after entering my
password, the screensaver came back on and neither mouse movement nor
keystrokes would stop it. I was able to CTL-ALT-F2 to bring up a
console. I ran dmesg and noticed the following near the end:
[ 39.684336] Console: switching to colour frame buffer device 128x48
[ 39.684363] fb0: inteldrmfb frame buffer device
[ 39.684365] drm: registered panic notifier
[ 39.695973] acpi device:30: registered as cooling_device2
[ 39.696437] input: Video Bus as
/devices/LNXSYSTM:00/device:00/PNP0A03:00/LNXVIDEO:00/input/input12
[ 39.696545] ACPI: Video Device [VID] (multi-head: yes rom: no post: no)
[ 39.696570] [Firmware Bug]: Duplicate ACPI video bus devices for the same
VGA controller, please try module parameter "video.allow_duplicates=1"if the
current driver doesn't work.
Could that last line be a clue? How do I fix it?
