Thanks @Ryan for the post. I'm not sure in this case that a bisection would be the most effective cure. There must be many many legacy Dell and other machines that are affected but we never know because people give up on the install. I think the suggestion (see somewhere above) of defaulting to having the workaround "Video=SVIDEO-1:d" enabled by default would be much more useful. The probable minority of users who do need to use SVIDEO could be dealt with through release note information and pointed to a legacy driver.
As an enthusiastic and fervent champion of Ubuntu I cannot emphasize enough the negatives a fraught install/upgrade process for non-IT users inflicts upon the reputation of the project. Far better to have a few non-working features than to alienate a whole section of users with legacy machines. After all, is Ubuntu not supposed to be "Great for use with legacy machines."?? My experience rendered a working system on 16.04 LTS totally unusable by the automatic upgrade to 18.04 LTS. I am surely not alone!!!?? -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1685442 Title: Errors: flip_done timed out during boot-up; slow boot Status in Linux: Confirmed Status in linux package in Ubuntu: Confirmed 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. --- 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.
