Bug Description

With Ubuntu 18.04 + Kernel 4.15, at boot time there are many periods when the boot freezes before the timeout of 10 seconds with Intel Mobile GM965/GL960 Integrated Graphics (driver i915).
In total it is 198 seconds that are lost in these timeouts during boot, more than 3 minutes!

Regression is present since linux kernel 4.8 (with Ubuntu 16.04).

To fix, explicitly disable the port with an i915 module setting with video=SVIDEO-1:d in the kernel command line parameter in the bootloader.
1/ sudo gedit /etc/default/grub
2/ add "video=SVIDEO-1:d" to "GRUB_CMDLINE_LINUX_DEFAULT" line
3/ sudo update-grub

After applying this, the system boots up much faster, there are no "drm ... timed out" messages.

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.16 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

@jsalisbury It is definitely not fixed upstream. See https://bugs.freedesktop.org/show_bug.cgi?id=93782

Same bug with Linux Mint MATE, kernel 4.15.0-42, GPU Intel Mobile GM965/960, module i915.
Adding "video=SVIDEO-1:d" works.

Same bug here, with Ubuntu 16.04 and kernel 4.15.0-43 (LTS enablement stack) using Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (primary) (rev 0c) on DELL inspiron 1525.

Tried with liveusb ubuntu 18.04.1 and same symptoms.

Under Ubuntu 16.04, adding "video=SVIDEO-1:d" solved the problem !

Same bug here:
lubuntu 18.04 32bit on Dell Latitude D530. Fully updated today 25/1/19.
Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller
Kernel: 4.15.0-43-generic

The bug caused a very long boot with blank screen (around 5min), and similar when returning from a locked screen.

The above fix from jsalisbury worked perfectly - completely solved the problem.

Hello,
I have a DELL PA-10 wtih GM965 intel graphic card. It couldn't boot with 4.15 kernel and I have to use 4.4.0. I'm using the default driver, I didn't find an other.

The computer boot faster aplying this fix but I continue to have a problem with the suspension. After after a suspension the screen blink between two kind of blank screen and never start.
Is there a solution for that?
Thanks,
