Just a short comment, I did the bug report without the workaround, hence the linux boot command line is "standard" as a fresh install, without the parameter "video=SVIDEO-1:d" that workarounds the bug.
I imagine it is more significant that way! Should you need a report with the workaround included, I can do that too. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-signed in Ubuntu. https://bugs.launchpad.net/bugs/1774845 Title: TV-out timeouts in i965 driver (since recent kernels ~4.4) Status in linux-signed package in Ubuntu: New Bug description: This is the automated ubuntu-bug linux 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.
