** Description changed: 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. + So I'm solving the problem for myself by using Ubuntu Mate 16.04.1 LTS rather than 16.04.2. + --- + ApportVersion: 2.20.1-0ubuntu2.5 + Architecture: amd64 + AudioDevicesInUse: + USER PID ACCESS COMMAND + /dev/snd/controlC0: test 2194 F.... pulseaudio + DistroRelease: Ubuntu 16.04 + HibernationDevice: RESUME=UUID=a754e82c-72cb-44d1-9fa4-58777803b24d + InstallationDate: Installed on 2017-07-19 (0 days ago) + InstallationMedia: Ubuntu-MATE 16.04.2 LTS "Xenial Xerus" - Release amd64 (20170215) + MachineType: Dell Inc.
