Dell UP3218K | An “8K” monitor at 32″ via 2x DisplayPort

Promotional Page

Does it work with Linux (Wayland Weston etc.): UNKNOWN.
There is no clear positive statement that it does… or does not.

The headline specs are all those fun “little lies” that commerce gets to flourish itself with …wherein “8K” equals 7600, and “32 inches” equals 28.4″ etc.

Specifications

  • “8K” = 7680 x 4320
  • 32″ = 31.5″ =28.4″ × 8.5″ × 24.3″
  • 17 Kg = 37.47 Lbs.
  • 60 Hz
  • 2x DisplayPort 1.4+
    Something about HDMI 2.0 maybe.

Folklore

From the Drivers & Manuals subpage

  • May or may not be Windows Only
    Some commentariat that MacOS is “not supported.”
    Claimed <quote>All NVIDIA 10xx cards, and their TITAN line, support 7680×4320@60Hz natively.</quote>
  • Requires both cables to provide the “8K” mode.
  • Which graphics cards are supported?
  • AMD video cards may or may not be supported.
  • Intel HD Graphics may or may not be supported.

Continued characterization, but no solution, for the Dell M3800 with Fedora 21 and Broadcom’s Bluetooth brcm/BCM20702A0-0a5c-216f.hcd binary blob

Continuing: Bluetooth seen working on the Dell M3800 with Fedora 21 and Broadcom’s Bluetooth brcm/BCM20702A0-0a5c-216f.hcd binary blob, still not solved, or ameliorated.

An example of syslog messages from a boot trace where the firmware was loaded correctly, three suspend-resume sycles occurred with the firmware failing to (re)load on the third cycle.

You need the symlink.

Summary

  • When loaded, the blob seems to work (bluetooth works).
  • Yet it can fail in place; perhaps after a suspend-resume cycle.

Revision

  • Something else is going on.
  • Sometimes the firmware loads.
  • Sometimes the firmware fails to load.
  • It may have something to do with the crashes, hangs & heating observed in multiple suspend-resume cycles.

Frustration

Trending towards: Does Not Work With Linux
This is still a hobbyist’s & enthusiast’s machine; it can’t be used for production work except in the factory-install configuration.
Dell delivered a working machine.  Aftermarket conversion to Fedora is nearly unuseable.
If it weren’t for the 4K display, this machine would be AVOID.

Following up from: Experiences with the Dell M3800 with Fedora 21 and Broadcom’s Bluetooth brcm/BCM20702A0-0a5c-216f.hcd binary blob

Indeed, the gear does work with the factory-prepared Ubuntu 14.04 LTE that Dell installed.  But it has so much blobbery and idiosyncratic non-open hardware that you won’t be able to upgrade beyond what the Dell team was able to assemble.  It is unknown how they were able to assemble a working configuration.

It’s 2015 and GPUs still don’t “just work.”

I did mention it has a 4K2K display, right?  That’s why we’re here.  That’s a can’t-live-without thing nowadays.

Goal

  • “just works”
  • bluetooth “just works”
  • graphics “just works”
  • suspend “just works”

Mentions

  • There is a blob
  • You have to get the correct blob
  • You need to make a symlink nearby to the blob.
  • Debugging whether the blob loaded or was caused to load-but-failed  is murky.
  • Something about the udev subsystem.

From /var/log/messages

Hardware name: Dell Inc. Dell Precision M3800/Dell Precision M3800, BIOS A09 01/08/2015

UNSOLVED: Dell M3800 Fedora 21 – more hangs and spews ERROR @wl_cfg80211_get_station : Wrong Mac address, mac = c0:c1:c0:07:86:41 profile =00:25:9c:63:75:8b

Previously

The machine is rapidly becoming unusable. Especially delicate is that screensaver & display blanking faults require a power cycle.

  • Upon screensaver, the graphics faults and is “hung” → one must power cycle to recover control.
  • Upon suspend, the CPU (GPU?) runs hard, it gets hot and hangs → one must power down to recover control.

(UNSOLVED) Dell M3800 under Fedora 21 (but not Dell-Factory Ubuntu 14) does not suspend, runs super-hot, hangs

UNSOLVED: Dell M3800 under Fedora 21 (but not Factory Ubuntu 14) does not suspend, runs super-hot, hangs

Indications

Fedora 21 is substantially unuseable except in “immobile” modes.  Upon closing the clamshell to transport, the CPU, GPU & fan run hard and it gets extremely hot.  The unit will not respond on the NIC, the keyboard or anything.  A powercycle is required.  To transport, one must power down.

This does not occur with the Dell-installed Ubuntu 14.04 LTS.  That configuration suspends & resumes appropriately.

Estimate

Seems like the Fedora system is using nouveau while the Ubuntu system is using i915 (Intel).  Both systems have a Quadro K1100M GPU.

Also the use of external displays.   I didn’t test Dell-factory Ubuntu with external displays.  I did exercise Fedora 21 nouveau with an external display.

Remediations

  • Fedora → None known.
  • Ubuntu → Stick with the factory-installed Ubuntu, learn Ubuntu, hope it doesn’t break.

Hardware

  • NVIDIA Corporation GK107GLM [Quadro K1100M]

Differences

  • Fedora 21 → uses nouveau
  • Ubuntu 14.04 LTS → extensive blacklisting of nouveau
    • nvidia_340 is used
    • all other nvidia is blacklisted
    • nouveau is blacklisted
    • See /etc/modprobe/modprobe.d

References

  • Precision Mobile Workstation M3800 Keyboard Guide
    • FN+Insert → “hardware sleep” unlabeled
      is apparently different than powerbutton “software sleep”)

      • Effective when the Power button (tap) does not
      • Yet is ineffective when the GNOME screen saver is active.

Bringing up wirelessness (wlp6s0) on the Dell M3800 under Fedora 21

Solution

You need the packages

  • broadcom-wl
  • kmod-wl

Automatically

  • With the correct driver module installed, it “just works” on boot.

Manually

  • modprobe wl

Witness

$ ip addr show wlp6s0
5: wlp6s0:  mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
    link/ether c4:8e:8f:f4:ec:fd brd ff:ff:ff:ff:ff:ff
    inet 192.168.1.64/24 brd 192.168.1.255 scope global dynamic wlp6s0
       valid_lft 3563sec preferred_lft 3563sec
    inet6 fe80::c68e:8fff:fef4:ecfd/64 scope link 
       valid_lft forever preferred_lft forever

Original State

  • Works under the factory-installed Ubunto 14.14
  • Not recognized under stock Fedora 21 (wlan0 does not even show up).

Previously

  • Bringing up Fedora 21 on the Dell M3800 with a 4K2K Display; herein; 2015-07-07.
    tl;dr → partial success in bringup

    • wireless networking → unsolved (solved here)
    • wireline networking → solved (pesky dongle)
    • HiDPI Display → solved (GNOME settings)
    • Bluetooth → partial, you need a blob, the blob survive suspend-resume; status.
    • Suspend/Resume → UNSOLVED remains not working (does not suspend, dangerously overheats, arbitrary hang of the GPU); this makes the machine substantially unuseable beyond the hobbyist/tinkerist use case. status
  • Dell M3800 Mobile Workstation, ships with Linux, herein; 2015-03-31.
    tl;dr → promotional images, references to the promotional history

Dell M3800, ships with LinuxDell Precision M3800 Mobile workstation, ships with Linux

Configured
  • Ubuntu, surely it will work with Fedora
  • 4K2K display (3180×2160)
  • 16GB RAM
  • 1TB mSATA
Standard
  • NVIDIA Quadro K1100M
  • 4th Generation Intel i7 (Haswell)
Issues
  • No RJ45 Ethernet; need a USB-to-Ethernet dongle. :-(

Factoids

  • Broadcom Corporation BCM4352 802.11ac Wireless Network Adapter
  • Fedora 21
  • Kernel 4.0.6 (upgraded from the stock install)

Folklore

Based on information, belief & hearsay, as seen written.

  • Broadcom is not “well-supported” in Linux prior to kernel 3.17.x
    Atheros & Intel are “well-supported”
  • Something about the 3.17 kernel not working with kernel 3.17

Somewhat SOLVED: Bringing up Fedora 21 on the Dell M3800 with a 4K2K Display

Just Works … (almost)completely

  • Installation of Fedora via wireline ethernet (network install) is not possible
  • Installation of Fedora via wireless network not offered.
  • Installation of Fedora via (legacy BIOS boot) USB media … just works.
  • Wireless networking does not work under Fedora [NOT SOLVEDSOLVED]

Once Fedora (Fedora 21) is installed, the network works as it should.

Background

Wireless Network

Does not work.  No wireless networking capability is recognized by Fedora. It worked under the native Ubuntu from Dell.  TODO.

Wireline Network

There s no win or workaround here.  Dell does not provide a wireline NIC on the M3800.  The USB dongle is not supported in BIOS during the network install scenario.  You lose.  You must use a USB stick.

Some dude explored all the options in Dell laptops, including the M3800 to assess which of the BIOS and USB-to-Ethernet dongles would “work.”  Windows-centric (there is some sort of Windows7-vs-Windows8 issue going on for that culture).  The net of the issue is that while the in-ROM PXE will operate the USB-to-Ethernet dongles for long enough to bring over a kernel, once the kernel itself attempts to assert control over the devices from PXE, then the USB controller drops back into HCI mode only, the network-capable hardware “disappears” off the USB bus.  There is no workaround, it is a (legacy) BIOS thing; UEFI does not support network booting in this scenario at all.

HiDPI Display

The whole point of this machine was the 4K2K display.  Wiithout intervention, it render similarly to an HDMI display, that is comfortable to read at 15″; to get it to use the full native resolution, which can be uncomfortable to read at 15″ you will need some settings.

To avail yourself of the “High DPI” screen you will need to establish that in GNOME, else you’ll have what amounts to a HDMI-scale screen.  At runtime, within a GNOME session, declare:

gsettings set org.gnome.desktop.interface scaling-factor 1

This wasn’t necessary when using a 31″ display (on Fedora 19 & Fedora 20), but is absolutely necessary using a 15″ display (on Fedora 21).

Definitions

<quote> cite=”ref”>HiDPI (High Dots Per Inch) displays, also known by Apple’s “Retina Display” marketing name, are screens with a high resolution in a relatively small format. They are mostly found in Apple products or high-end “ultrabooks”, as well as in 4K (Ultra HD) or even 5K monitors.</quote>

<quote cite=”ref“>Hi-dpi support means that applications render at half the available screen resolution to avoid content that is defined in terms of pixels from becoming tiny. Effectively, this means treating 2×2 blocks as device pixels as application pixels, with the extra twist that data that is available in high resolution (e.g. svgs or fonts) can be rendered at the full resolution. </quote>

    tl;dr → discursive, not very helpful avoids any mention of gsettings or org.desktop.interface.scaling-factor, mentions gnome-tweak-tool but not what to do with it, discusses detailed application-specific workarounds (avoid these, GNOME works just fine with scaling-factor)

    tl;dr → this is not a “problem” in Xorg, rather it is a feature of HiDPI displays
    Useful

    • /var/log/Xorg.0.logno longer exists in Fedora; each release has a different way of recovering the logfile, perhaps the changes have stabilized
      • Fedora 22 → journalctl -b _COMM=gdm-x-session
      • Fedora 21 → journalctl -b _COMM=Xorg.bin
      • Fedora 20 → journalctl -b _COMM=Xorg
      • Fedora 19 (& prior) still used /var/log/Xorg.0.log

Folklore

  • Use scaling-factor 2 to get something approximating an HDMI (HD-type) resolution.
  • Use scaling-factor 1 to get the native resolution
  • Use scaling-factor 0 to get (what?)
  • Use gsettings reset to recover the default
  • Use gsettings get to recover the current setting.
  • Of course, gnome-settings-daemon must be running.
