My Latitude E6430 has the same option and it can be configured in the BIOS. It turns off all LEDs, the display and the sound.

Yep I tried and indeed it is *too* much. I was hoping for the leds only.

I upgraded to networkmanager 1.4 and cannot connect to the WiFi anymore. Anyone getting the same with the Broadcom card?

Check the wiki for a workaround
https://wiki.archlinux.org/index.php/Br … ager_1.4.0

I'm still having issues with Wifi connection, even after the two upgrades from yesterday. I notices that the paragraph with the proposed fixed on the Broadcom wiki page Justme posted was deleted.
Is the issue still present for you? If yes, does someone maybe lnow why the proposed fix was deleted from the wiki?

It was deleted because it was an issue documented for a specific version of networkmanager that got fixed in the most recent update. You can try it nonetheless, but I cannot ensure you will solve your connection issues.

lukypie · 2016-09-01 15:44:46

Same problem, I must use wifi-menu every time because NetworkManager seems to have stopped working.

You mean for wifi? There's a problem in the latest NM version, you can either wait for the new one which is patched, or downgrade NM, or use the workaround that is indicated in the XPS13 thread.

The new update didn't fix anything for me. I'm still having the same issues

I was also having issues a day or so ago, but the latest version of NetworkManager works for me.

EDIT: Nevermind, on the new version (1.4.1dev+15+g0d23ffd-1) I can connect initially but after waking from suspend NetworkManager can't find any wifi networks. Reverted back to 1.2.5dev+5+g99e34d7-1 and everything is fine.

I guess I fucked it up, even downgrading doesn't help. It's a constant scanning,

<warn>  sup-iface[0x1e207a0,wlp2s0]: could not get scan request result: Timeout was reached

It's a shame that basics are broken, considering that even my phone is handling wifi connection way better than my arch ((

Look here :

and the workaround...

Tallix · 2016-10-01 21:37:07

After some initial testing, my issues seem to be fixed with NetworkManager version 1.4.2-1. Initial connection works perfectly, and my previous problem of not properly discovering networks after waking from suspend is gone. If I have any issues I'll post an update here.

Caspian · 2016-10-02 14:38:16

Is anyone experiencing performance issues with graphics when on battery power, using QHD resolution and UXA (gnome completely freezes if I use SNA)? I'm using gnome and only intel graphics card (Nvidia is disabled).
One more thing I noticed is that gnome doesn't show all display resolutions (only the QHD one is in native [16:9] format, all the other resolutions are in 4:3 format). Interesting thing is that I don't have the issue with available resolutions when I connect external monitor via HDMI (in this case all resolutions are shown for laptop internal display).

Hi all,
I finally figured out the cause of all the crashes I had, and you will not believe me. It's hardware.... but it cannot be reproduced by Windows!

What happens? Sometimes, when I lift the XPS from the table, I get what looks like a kernel panic: no input, audio cycling, have to force shutdown.
I tried to reproduce this and lo and behold this happens when I press with a bit of force on the back cover, specifically over the middle of the aeration grid. It does not require extreme force, it's sufficient to lift the computer with a single hand with the palm in the middle of the base. If I press more, the screen flickers, turning on/off with the same timing as my presses.
This happens no matter if the laptop has been turned on for hours or for seconds, temperatures have no importance too.

This issue CANNOT be reproduced on Windows!

Anyone has any idea? This is driving me crazy.

EDIT: Just tried 4.4 LTS aaaaand... no kernel panic. What is happening here? A mix of HW and SW faults?
EDIT EDIT: and now updated BIOS from 1.02.00 to 1.2.14 and no more crashes... this machine is haunted!
EDIT EDIT EDIT: No, it's Hardware, I can reproduce it on Windows too now...

By the way, anyone having problems with 4.8.3? I use 4.8.3-ck and I cannot boot (black screen). Standard vanilla 4.8.2 works fine.

Pure conjecture, but things like memory controllers can be configured to run the bus a different speeds. Perhaps Linux had been configuring it differently than had Windows. Change the kernel could result in a different configuratio. A BIOS change could change the way the kernel configures things as well. Like I say, pure conjecture.

5 minutes ago I had it crash again. So I fired up Windows and managed to reproduce the issue there too!
So it looks like it is a 100% hardware issue, Linux has nothing to do with it, and it appears it is a bit erratic in showing itself. I use Windows very rarely so by pure chance it never showed there even when trying hard to reproduce it.

I am on 1.2.14 and 4.8.2-1. Right after install (4.7 kernel) about an month I had few bugs with suspend, audio jack (no sounds even after reboot). Now all of this issues is magically disappeared - suspend works fine, headphones hot plugging too.

Does anyone have issues with backlight after suspend?
After I wake the laptop from suspend the laptop display stays black. I need to press the button for backlight increase several times for it to turn on. The display reacts only to two backlight levels (completely turned off and full brightness).
I'm on the latest kernel (4.8.4), using Gnome and have acpi_backlight=native kernel parameter set (other acpi_backlight options work poorly for me).

Ok so I never had problems with audio until lately.... And I can't figure out what's the problem.
Sometimes I can fix it by playing some audio file while suspending and resuming... sometimes not.
One thing that bugs me is that when I use the USB-C to connect to a screen, the audio (both on the laptop and the screen) always seem to work.
Any idea how to find this bug and where to report it?

for me helps just connecting usb soundcard (from my old logitech headset). it works then even after disconectting.

I have the exact same model as OP:

Dell XPS 15 9550, i7, 16GB, 84WHr, FHD, 512GB NVMe SSD

Upgraded to G Skills's 2800mhz 2x16GB DDR4 SO-DIMM modules and replaced the useless Broadcom-card with a Intel Dual Band Wireless-AC 8260 mini-PCI card bought from Ebay.
The whole upgrade process took about 10minutes.

Anyway, I use the latest BIOS (A13, 1.2.14) with the backlight fix for resuming instead of black screen (google), and everything works great - although had to remove the sleep.conf in /etc/systemd/ before hibernation worked.
This may be due to other stuff though.

I would HIGHLY recommend upgrading if not the RAM, at the very least the WIFI-module.

This is my commandline with Grub (hidden, timeout 1):

cryptdevice=UUID=37f444cb-09d7-45c8-976e-a2dcea0afc16:aes root=UUID=a8758fb2-a8d5-4807-b31c-e0f5f38205cd rootfstype=reiser4 rootflags=noatime,txmod=wa rw resume=UUID=732b004a-a95a-40ff-a384-1676a3fec080 scsi_mod.use_blk_mq=1 drm.vblankoffdelay=1 ipv6.disable=1 nmi_watchdog=0 pcie_aspm=force acpi_backlight=native systemd.restore_state=1 acpi_osi='!Windows 2012' acpi_osi='!Windows 2013' acpi_osi='Linux' loglevel=3 quiet

As you can see, I run a custom kernel which is just around the corner in regards to upgrading to 4.7.x with the latest Reiser4 patch, using lzo compression - which even with TLP set at max 30% of performance at battery, is INSANELY fast compared to my older 13" inch Zenbook with a Core i7-6500U, even having a longer battery time aswell.

powertop says I use about 10-11w per hour with this setup (slightly increased RAM power usage because of frequencies) while having the brightness at minimum (which still took a while to get used to being so bright), wifi on, bluetooth off (with the hotkey, which is perfect disabling only the bluetooth module.) and listening to spotify while typing this in Chromium with 5 tabs open and 4 terminals.

So with a big battery like this, this is a real powerhouse in terms of both performance and mobility imo. Nvidia card is managed through bbswitch-dkms and bumblebee which works perfectly (I chose to set the PCI device id in xorg.conf.nvidia though)

Anyway, being a custom kernel, I dont have the dell_wmi, dell_laptop or other dell-specific modules (I have seen no other LEDs besides the power button?) besides the "Dell base system management" module (or something like that) - but which probably (if not deprecated) will be included in kalterfx-4.7.x.

But even without that, I have no troubles with this setup. All hotkeys work (only while running with the mentioned acpi_osi lines though).

Dmesg:
https://paste.pound-python.org/show/eJO … Zj9JAwzEO/
...Alot of the ACPI warnings/exceptions and even errors disappear if I activate ACHI - but I see no need for that as they are benign in cases where it is not nessesary.
There are events which mentioning having trouble reading the AC adapter state - which is not the case even in Cinnamon or TLP (although with a quirk I also had to use on my Zenbook, seems to appear on many Skylake laptops).

TLP udev rule:
https://paste.pound-python.org/show/e6n … XNzKMswcM/

In bios I have disabled every feature I dont use:

* Disabled ACHI completely (so some ACPI warnings are because of this)
* Disabled legacy boot, WLAN wakeup, etc.
* Removed the SATA0 & SATA1 ports (as I only haave the M.2 SSD anyway)
* Disabled TLP (using software encryption with LVM-on-LUKS) ... aswell as all of the other useless stuff like OS recovery and stuff. 
* FastBooth set to Minimal - not thorough - more warnings with minimal but less support in Linux with my kernel at least.

(Have tested both, but not Auto, and while it takes a bit longer with thorough, on my setup the wireless hotkey (F12) wont work, so Minimal for me.)

This is a system running just Linux though.

I sometimes can get an error with the firmware for the 8260AC card but that is really random and is probably related to the bluetooth module which is hardware-disabled through the hotkey and does not even appear in 'rfkill list' after deactivation and stays that way until the hotkey is pushed again.

I also use libinput only, and use this config (40-libinput.conf), though not perfect, but good enough for me with the settings in Cinnamon:

https://paste.pound-python.org/show/222 … lw2HySQHN/

xinput -list gives me:

https://paste.pound-python.org/show/qj8 … 1lo3nDpiU/

So no Dell touchpad for me. Does not bother me.

Only real issue I have had is that if I suspend the laptop while my USB 3 to Ethernet-dongle is connected, the computer shuts down instead of suspending. Dont know if its still the case after modifying boot options.

moesi · 2016-10-31 15:05:59

Does anybody have "problems" with noisy fans when an external display is connected? (FullHD external display, it happens with HDMI and also with USB-C (to HDMI))
It is pretty annoying. I have the i7-6700HQ, none glare)

cheers

Hi! I have a very similar model but I can't seem to get suspend working consistently. I added this to the boot loader entry:

acpi_backlight=vendor acpi_osi=Linux i915.preliminary_hw_support=1

And then it worked, but I could no longer control my backlight. So I left the first parameter out, which made it reverse again: backlight but no suspend. However now for some reason, I can't get suspend anymore at all. It wakes up but shows a black screen. Is it possible this has something to do with GNOME using Wayland?
