[Bug 1410921] [NEW] no sound devices, bad video resolution on laptop screen, no external monitors detected
Public bug reported:
sorry for the meta-bug here, but just upgraded from
linux-image-3.18.0-8-generic: /boot/vmlinuz-3.18.0-8-generic
to
linux-image-3.18.0-9-generic: /boot/vmlinuz-3.18.0-9-generic
and now:
a.) I don't seem to have an audio device ('settings -> sound' shows only 'Dummy Output')
b.) my LCD screen is in 1280x800 resolution rather than the 1364x768 that i'd expect.
c.) external monitor is not detected.
xrandr shows:
$ xrandr
xrandr: Failed to get size of gamma for output default
Screen 0: minimum 1280 x 800, current 1280 x 800, maximum 1280 x 800
