Title:
Errors: flip_done timed out during boot-up; slow boot
Status in linux package in Ubuntu:
Incomplete
Bug description:
I had been running Ubuntu 16.04 LTS on many laptop computers
(especially Dell D620, D630, E6400) with no problem.
I created a Live USB with Ubuntu 16.04.2 LTS and tried it on a Dell
D630. It was very slow to boot up (about 90 seconds) as opposed to
the 30-45 seconds it usually takes. For a few seconds there were error
messages that included the phrase "flip_done timed out".
When the Ubuntu desktop appeared, the mouse cursor hung for a while,
but then came back to life. I didn't do much testing from there. I
did a Live session with the 16.04.2 LTS on a different D630 laptop,
and the same problem occureed.
I Googled the problem, and found several hits.
-----------------
On an Arch forum, someone reported the problem on a Dell D630, like mine. It
also occured on other laptops:
https://bbs.archlinux.org/viewtopic.php?id=218581
The suggestion was that the bug was related to kernel version 4.8.x
and the 965GM chipset, which is what the D630 has.
So I tried Ubuntu Mate 16.04.2 on a Dell D620 (with a 945GM chipset) and the
problem DID NOT occur.
-------------------
For a similar boot-up problem, Ubuntu Forum suggested going back to an
earlier version of Ubuntu.
https://ubuntuforums.org/showthread.php?t=2348892
I tried Ubuntu Mate 16.04.1 (with the 4.4.0-31-generic kernel), and
the problem did NOT occur.
So I'm solving the problem for myself by using Ubuntu Mate 16.04.1 LTS
rather than 16.04.2.
