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.
