TypeMatrix 2030 and some random HP mouse that was laying around the office, both of which work fine when plugged straight into a Type A port on the laptop.
I'm definitely hoping this isn't some bizarre motherboard issue with my XPS that I need to file a return on Amazon for. That'd be quite a mess to deal with...
EDIT: Can confirm after messing with the docks in my Windows partition, this is definitely an issue that is isolated to Linux.
Sorry, I couldn't find anything for Typematrix gl!

Hi,
I'm trying to find out how long the battery will last.
There is different information spread arount the net....
Can any tell me his battery life? I'm very interesteded in QHD+ screen.
Additional informatino like WM would also be useful.
Thanks!

I have QHD+ screen, but the problem is NVMe SSD disk, it doesn;t go to lower states, on idle the system consumes 5.5-6.5W, where 3.1W is SSD because of lower power states are not supported, waiting the kernel powersave for NVMe implementation. After that SSD will go to 0.005W on idle, and power consumption will be the same as non NVMe models. you can try to swap NVMe to sata SSD and compare.

Currently with 4.6 kernel and rc6 power saving active power consumption with normal usage should be around 4-6W with a SATA ssd and 5-9W with an NVMe ssd, on an average over multiple hours.
Things will improve, hopefully, with newer kernels which sooner or later should make PSR and FBC (which are power saving techniques) viable. Right now they are buggy.

Hi everyone,
I'm wondering if anybody managed to solve the touchpad bug which appeared since 4.5 kernel.
Currently - with libinput installed and 4.6 kernel - 3 fingers touch randomly switches the touchpad to y-axis mode and a second 3 finger touch is needed to revert it back to normal.
Does somebody have information about this issue ?

Hi everyone,
Finally I got an official response from Dell's Customer Support:
Regarding our conversation today, we currently have no support for Thunderbolt/USB-C ports on our Linux systems, as all of the drivers and firmware are Windows-specific. I’ve been told that they want to have firmware/drivers in the future, but we have no ETA or timeline for that right now, it might not even be this year.

That's interesting. Why don't you ask why in this case they are specifically selling their USB-C adaptors with Linux support as a listed feature. Because if the above is true, then Dell are committing a crime under EU consumer law and are heading for a world of hurt. Also, I specifically asked them for mine if they can confirm Linux support and they did.
It could be the general case of support half-arsing it as a whole and giving the wrong info, but it will be interesting to see what they say.

What does this exatly mean? Which Adapters are working, which not? What about TB15 Dock? Ist it working at all?
Would be great to add some information about this to the Wiki article.

#9376, It seems for docks, everyone is having variable outcomes. For example, I have a WD15 dock and all my usb periphals are working (just needed the keyboard driver for linux [ckb from aur for corsair]). Ethernet, sound output, hdmi, vga, etc are all working fine for me. For some others, they are having unstable outcomes like usb resetting or ethernet switching on/off every few seconds. So it is hard to write about it since we haven't gotten more input or what works and doesn't work. For now, it is a gamble. I think there is an existing bug report on bugzilla for tb15 though. Never played with one so not sure what the progress is.

I had such problem since 4.5 kernel (rc releases). As workaround I used the module psmouse blacklisting the i2c_hid one. This fixed the problem but I always had a different feedback (less sensible) with this driver.
Since one hour I'm testing a patch proposed by a Dell developer on a kernel bug report: https://bugzilla.kernel.org/show_bug.cgi?id=112791
I've obviously switched on i2c_hid driver too restoring the original good feedback I had. It looks that this patch is working. I'll wait the end of the day to give a feedback to the developer. Feel free to test this patch.

Hey guys!
I'm on 4.7.0-0.rc4.git0.1.fc25 kernel, and everything works well so far.
I've noticed the wifi driver hang has been merged into the 4.7 branch and it doesn't crash any more. I still use "pcie_aspm=force i915.enable_rc6=7" but don't know whether they are useful of not. Mine it's the 256GB + QHD + i7-6500U, still battery life sucks a bit (aroudn 7W when on, firefox open and brightness to the minimum).
Hope it helps!

Great thanks. Everything seems flawless now.
The developer should push this patch upstream as you suggested.

You must retreive the kernel sources, get the .patch file, and rebuild the module with the patch applied before replacing your existing one.
I suggest you to read this wiki page and to enquire about the patch command before proceeding.

4.7rc3 has been great for me, no more problems with external DP monitors & suspend/resume (like I encountered on 4.4/4.5), and generally stable.
On my QHD+ screen I found that setting "enable_rc6=1 enable_fbc=1" together caused quite regular flickering. Disabling either of the options fixed it, but keeping enable_rc6=1 has the biggest power saving by far. Still notice it flickering very occasionally.
enable_psr=1 caused screen freezes, same as reported by other people.
enable_rc6=7 still shows up as "1" but powertop tells me that the deeper modes are reached.
Can you confirm you're really seeing RC6p & RC6pp in powertop? On my system, the driver identifies that only RC6 is supported. I documented it a bit on the wiki - if I enable debugging I see the exact "[drm:sanitize_rc6_option] Adjusting RC6 mask to 1 (requested 7, valid 1)" message mentioned there.

I also foolishly bought one of the OWC USB-C docks for the 2015 MacBooks, and this doesn't really work with my 9350 at all - but given they only advertise it as supporting MacBooks that's my fault not theirs. Shame though. I haven't had a chance to see if it works any better with Windows.

I have a very basic question, to which I couldn't find a satisfactory answer. Will it work, to connect the laptop with a projector using any USB-C to VGA adapter? Or, specifically, does Dell's 470-ABNC adapter work without problems? I want to save myself the trouble of ordering something which doesn't work in the end.
(I have the FHD developer edition running Arch.)

I used the official Dell USB-C to VGA adapter in class in the last semester: it worked well but I used standard resolution projectors (1024x768). I don't know if it can work with higher resolutions.

Thanks a lot for your feedback. Meanwhile I obtained a noname USB-C to VGA adapter and I found that it just works. The highest resolution I got was 1600x1200. When I unplug the adapter KDE sometimes behaves in a weird way, but for the practical purpose of showing a presentation it's usable. This is important for me.

Hi everyone!
After installing a fresh Arch on top of my new XPS13, I am facing a buzzing noise.
After checking, it seems related to the driver intel.
Does anyone manage to solve fully the problem?
I already found some tips, like uninstalling xf86-video-intel, but noise is still present.
Offline
Tricky one - I ended up returning the laptop to Dell & got a replacement.
I can still hear the buzzing with the new one, but its much lower in volume than the original.
I'd love to hear any ideas for how to address this. So far I have found:
- The noise seems to originate somewhere around the a/s/w keys.
- It changes when using the trackpad.
- Sometimes its not there at all.
- The noise reduces when not plugged into mains.
- It could be coil whine.

In my opinion, it is really GPU related..
If I switch off my compositor (Compton), the buzz is way less audible.
Add that to the fact that when on TTY, there is no noise at all.
Of course no log mentioning any issue (That would be sooo much easy).
