victor gaspar, thank you for reporting this and helping make Ubuntu
better.
1) Could you please provide the full computer model as noted on the
sticker of the computer itself (not from the Bug Description, or the
result of a terminal command)?
2) To see if this is resolved in your release, could you please update
your HWE stack as per https://wiki.ubuntu.com/Kernel/LTSEnablementStack
and advise to the results?
3) Could you please advise if any one (not in combination) of the following
kernel parameters allow you to boot:
nomodeset
radeon.dpm=0
radeon.bapm=0
radeon.bapm=1

- The laptop starts up fine but the screen is black; even though the screen is
black I can hear the drum sound prompting me to log in. After rebooting laptop
all is well with the screen and I have a fully functional system. Sometimes,
though, I have to restart twice.
