[21:01] <dupondje> Known issues with latest kernel in Saucy ?
[21:14] <dupondje> what the
[21:14] <dupondje> Jul 20 22:08:19 laptop-jl kernel: [   38.945777] i915: Unknown parameter `i915_enable_rc6'

[21:25] <dupondje> aha
[21:25] <ubot2`> Ubuntu bug 1203211 in linux (Ubuntu) "Kernel 3.10.0-4 fails on graphical boot with i915 (MacBook Pro 8,2)" [Undecided,Confirmed]
[21:43] <infinity> dupondje: If it's an Optimus system, can you confirm that it works fine if you disable discrete graphics entirely in the BIOS?
[21:44] <infinity> dupondje: (Mine's an Optimus, but I disable the nvidia part normally, and I'm not seeing this bug, so I'm curious)
[22:01] <dupondje> infinity: I have no bios option for that
[22:06] <infinity> dupondje: Oh, nevermind that then.
[22:08] <JanC> I don't think MacBooks have a BIOS  ;-)
[22:08] <dupondje> JanC: its not only macbook affected
[22:08] <dupondje> Dell XPS15 here
[22:11] <JanC> right, but I think those have (U)EFI too, and not a (real) BIOS
[22:12] <JanC> I forgot if Optimus has the outputs on the Intel or on the Nvidia part?
[22:12] <dupondje> depends :)
[22:12] <dupondje> HDMI is on nvidia
[22:12] <dupondje> DisplayPort in Intel
[22:12] <dupondje> heh :x
[22:13] <JanC> and internal?
[22:13] <dupondje> internal ?
[22:13] <dupondje> internal screen is connected to both ofc
[22:14] <JanC> that's not really "of course" AFAIK
[22:15] <dupondje> why not ?
[22:15] <dupondje> seems quite logic you can use both cards for you internal scren
[22:16] <JanC> it might seem logic, but sometimes you need one to use the other
[22:16] <JanC> but like I said, I don't remember the details about Optimus
[22:17] <JanC> there are differences between multi-GPU laptop setups
[22:23] <JanC> seems like Optimus always uses the Intel IGP to output to the internal screen
[22:35] <dupondje> its strange -4 kernel broke down
[22:35] <dupondje> as there are no relevant changes in it :s
[22:37] <JanC> I wonder if the nvidia/nouveau drivers could do something wrong? (if they get loaded?)
[22:37] <dupondje> no changes in nouveau neither
[22:38] <dupondje> https://launchpadlibrarian.net/145284065/linux_3.10.0-3.12_3.10.0-4.13.diff.gz
[22:38] <dupondje> not much changes :s
[22:39] <JanC> there are changes to dependencies etc.
[22:43] <JanC> mostly version stuff though
