** Description changed: - This is the automated ubuntu-bug linux + Booting into a installed environment takes a few more seconds than + normal. - as requested per ticket - https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1682921 - - From the original bug where I posted (1731784) and the ticket I opened - upstream, this has been identified by Intel engineers as a regression in - the DRI i965 since kernels around 4.4 (where it was working). - - The regression produces timeouts (10 seconds) when the graphic driver - looks whether there is a TV out in the hardware. These timeouts are - repeated several times during the boot process, which makes the machine - very sluggish. - - Depending on the hardware, there is a simple workaround which is adding - a parameter on the boot command to instruct the graphic driver not to - look at TV-out. - - This workaround is perfect as far as I am concerned, because since the - hardware I use does not have TV-out, I am not losing any feature and the - bug is not triggered any more. - - ProblemType: Bug - DistroRelease: Ubuntu 18.04 - Package: linux-image-4.15.0-22-generic 4.15.0-22.24 - ProcVersionSignature: Ubuntu 4.15.0-22.24-generic 4.15.17 - Uname: Linux 4.15.0-22-generic x86_64 - ApportVersion: 2.20.9-0ubuntu7.1 - Architecture: amd64 - Date: Sun Jun 3 09:18:54 2018 - InstallationDate: Installed on 2018-05-07 (26 days ago) - InstallationMedia: Ubuntu 18.04 LTS "Bionic Beaver" - Release amd64 (20180426) - ProcEnviron: - TERM=xterm-256color - PATH=(custom, no user) - LANG=fr_FR.UTF-8 - SHELL=/bin/bash - SourcePackage: linux-signed - UpgradeStatus: No upgrade log present (probably fresh install) + WORKAROUND: Use kernel parameter: + video=SVIDEO-1:d
