Re: Dell XPS 13 9350 Late 2015
@roffe, I have added the extra patches that you've listed. I'll see how it goes for today. Thanks for the links. I've been getting some kernel panics, do you? Are the patches in my github all the patches you've used or am I missing something? https://github.com/frank604/Dell-XPS-13 … ne/4.6-rc3

Edit2: Also, the wd15 dock doesn't work with any kernel. I'm only having success with the 4.6 branch. 4.4 and 4.5 both aren't being too happy.

Re: Dell XPS 13 9350 Late 2015
BTW, does anyone have any news on the DELL OS dump for their version of Ubuntu? Better yet, if your laptop came with it, do you have recovery image you can post somewhere or identify any useful patches from Dell itself?

Re: Dell XPS 13 9350 Late 2015
Do you know if the proposed dsmethod patch works with the DA200 dell adapter ?
If so, can someone explain me how to apply it on the current 4.4 kernel ?

Hrm, I think it should as it fixes usb-c hotplugging. You can view my pkgbuild on my github to see how to add it. Few pointers.
1. Make sure the pkgbuild is pointing to the right kernel version you want to compile
2. updpkgsums is your friend
3. add patch file name to pkgbuild
4. add a line that patches the kernel with your patch
5. ???
6. profit
Look into modprobed-db to fasten your compile time to 8 minutes or less.

Re: Dell XPS 13 9350 Late 2015
I have an issue with the type-C usb connector. I have a type-c to vga converter, but it works only at times. I usually make it work by doing
xrandr --addmode DP-1 1920x1080
xrandr --output HDMI-2 --off --output HDMI-1 --off --output DP-1 --mode 1920x1080 --pos 0x0 --rotate normal --output eDP-1 --mode 1920x1080 --pos 0x1080 --rotate normal --output DP-2 --offthe second line being created by running arandr. But it is very buggy, and sometimes I have to try several time before the screen detects input from the VGA adapter. Sometimes I get an error about being unable to set crtc1 or something similar.
Does any of you have any experience w/ a type-c video adapter of any kind? Is there a way to fix this permanently so that the adapter gets recognized immediately (I would like to use the computer for presenting slides)?

Re: Dell XPS 13 9350 Late 2015
@navi_se, have you tried the usb-c hotplug patch (dsmethod)? also, why do you have to turn off hdmi output in xrandr? why not use a simple xrandr like
xrandr --output DP-1 --auto Offline

Re: Dell XPS 13 9350 Late 2015
Is this the patch you mean mean? I am not sure how to apply it, will this entail recompiling the kernel? Would you mind a few pointer on how to apply it?
I honestly produced that script by saving it as xrandr generated, my adapter only has a vga, so I never mind that line about hdmi, but I shall remove it. Note that the vga adapter does work, but for some reason the screen sometimes detect it and sometime doesn't, even when repeating apparently the same sequence of actions (boot, addmode, xrand etc.., plug in, plug out, plug ing [or other combinations])

Re: Dell XPS 13 9350 Late 2015
Yup thats the one. You can git clone my kernel if you want to try. Or manually do so. Keep in mind usb-c is a bit buggy as it is still considered new tech. Try the patch and then see if that resolves your issue. I have a strong feeling it might.

Re: Dell XPS 13 9350 Late 2015
About the touchpad problems with kernels >= 4.5: it there someone with an XPS 13 9350 (no Iris) that don't face any problem with stuck pointers or failing taps using kernels 4.5 or 4.6rc*? frank604?
I don't understand why this problem (in a released kernel version!) was not already solved (or at least properly raised): for me it is a stopping point in using any kernel >=4.5. It could be that there are some other variables in the environments (libinput/synaptics, kernel params, ...) that allow people to use such kernels without any issues with their touchpad. If some of these are willing to collaborate we could understand more about this issue.
Sorry for the noise.

Ok, could you argue on your environment?
- exact model, Iris? QHD?
- BIOS version
- Distribution
- kernel version, package or PKGBUILD? config?
- kernel params
- desktop environment
- libinput o synaptics installed packages
Thanks

Can someone comment on http://mjg59.dreamwidth.org/41713.html? I'd be interested in the output of the "Idle stats" tab in powertop with no load. Does it reach the lower power states?

I have managed to build, install and reboot the kernel from your github repo. Version 4.4.7 as any other version I wasn't able to build due to different errors. Unfortunately I see no difference when booting under it. It *seems* that it requires less attempt with running xrandr --addmode and xrandr -output etc.. but I cannot tell if this is an actual difference. The funny behaviour seem to manifest at random. Sometimes I have running the sequence above immediatly starts the screen and other it fails.
Here is my lspci -vv when the screen is on and working (relevant usb part, I guess). Is there anything else I can post to make sense of this?

Re: Dell XPS 13 9350 Late 2015
About the touchpad problems with kernels >= 4.5: it there someone with an XPS 13 9350 (no Iris) that don't face any problem with stuck pointers or failing taps using kernels 4.5 or 4.6rc*? frank604?
I don't understand why this problem (in a released kernel version!) was not already solved (or at least properly raised): for me it is a stopping point in using any kernel >=4.5. It could be that there are some other variables in the environments (libinput/synaptics, kernel params, ...) that allow people to use such kernels without any issues with their touchpad. If some of these are willing to collaborate we could understand more about this issue.
Sorry for the noise.
I updated from 4.4.5 to 4.5 earlier today and had the same problem with the touchpad (and mouse?). I then built the 4.6-rc3 mainline kernel from AUR, which only seems a little better than 4.5.
My XPS 13 9350:
i5-6200, 128GB SSD, 8GB RAM, FHD screen
Kernel: 4.6-rc3
Desktop: Gnome

I haven't had any issues with the touchpad :

- Proc : Intel(R) Core(TM) i7-6560U CPU @ 2.20GHz
- DE : KDE
- input driver : libinput
- Kernel parameters : rw quiet i915.enable_rc6=0

Re: Dell XPS 13 9350 Late 2015
People using libinput for the touchpad, what is your libinput.conf configuration ?
Because I build 4.6rc3 with frank604 PKGBUILD but the touchpad does not work. I first though it was because of synaptic and switch to libinput, but it still does not work.
@zetxx why do you enable then disable psr in the same boot up command line ? And elevator=noop still make no sense https://bbs.archlinux.org/viewtopic.php … 1#p1582201 .

Re: Dell XPS 13 9350 Late 2015
First of all thanks to all the guys on the forum that replied to my request.
This is my configuration:
- Linux Mainline 4.6-rc3 (today build)
- XPS 13 9350 QHD (no Iris)
- DE : Gnome
- input driver : libinput
- Kernel parameters : rw quiet
- BIOS : Latest (1.3.3)
Looking at the configurations reported by zetxx (no problems), bahaika (no problems) and novelistxyz (with problems like me) it looks that the main difference is the DE. At the first glance this doesn't make sense but it could be that Gnome enable some libinput options that raises the kernel problem (because it looks a kernel problem anyway...).
In order to investigate I would kindly ask to report the libinput options enabled (by the Desktop Environment system for you) in your systems, in other words the touchpad related section of the output of command 'libinput-list-devices'. This is mine on Gnome 3.20:

Re: Dell XPS 13 9350 Late 2015
@diraimondo:
Just now I turned i915.enable_rc6=7 and i915.enable_psr=1 to zero, rebooted, turned them back to 7 and 1 respectively, then rebooted...
Somehow the cursor freeze (which is kind of a freeze of the whole screen imho) seems to have gone away.
I am not sure why though.

Re: Dell XPS 13 9350 Late 2015
Can someone comment on http://mjg59.dreamwidth.org/41713.html? I'd be interested in the output of the "Idle stats" tab in powertop with no load. Does it reach the lower power states?
I would say it does.

Just tested on my 4.6rc3 the two options with values, respectivelly, to 7 and 1. Nothing is changed: my touchpad still stop sporadically to react to the click but I can always move the cursor with it. It's not related to the graphics card.

Not sure why turning those options off and on again would solve it...
Now few hours in, I haven't noticed any freeze.
In case this would help:

Yes, I did. I think I did not configure my config kernel build file correctly. I will build & test again.
