On Dell Inspiron 1525 auto upgraded from xubuntu 16.04 LTS 64bit to 18.04 LTS. This bug appeared.
Then tried clean install of Xubuntu 18.04.1 The bug appeared from moment of boot of cd. Bug present also in Ubuntu 18.04.1 Grub edit of Video=SVIDEO-1:d works. As a committed Ubuntu fan of years going on decades, I cannot adequately express my strong disapointment that a bug serious enough to prevent effective installation for many users remains on a live LTS distro some 6 months after release even after revision to 18.04.1 I was able to fix it, (sudo edit of grub) but most affected users would be unable to and simply walk away. How many people walked and therefore never escalated this bug because they never got far enough to be able to?? Come on development team! Please remember that Ubuntu is supposed to be about ease of use and the users!!!

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. --- 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.
