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.


  • “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.


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.

Experience with Let’s Encrypt certbot for Fedora 23 (fails)

At with Apache on Fedora 23+

sudo dnf install -y python-certbot-apache
Error: nothing provides python2-augeas needed by python2-certbot-apache-0.8.1-1.fc23.noarch
(try to add '--allowerasing' to command line to replace conflicting packages)


dnf install -y augeas
dnf install -y python-augeas

Therefore: certbot isn’t ready for Fedora 23 yet.

Fedora 22?



Nope … too big and complicated … it will never work … and they didn’t test it on Fedora anyway.

AOC Q2963PM 29″ Monitor with DisplayPort v1.2 in/out

AOC 29-inch IPS Q2963PM (21:9) LED Monitor; $379.00+T.

Features (Specifications)

  • Interconnect multiple displays to create a daisy-chain
  • 2560×1080 @ 60 Hz
  • Mobile High-Definition Link (MHL) to connect and charge the phone


  • It’s not entirely stated that it supports Display v1.2, it just says “DisplayPort” but it does have a DisplayPort output and the marketing collateral does exhibit a use in a daisy-chained scenario.
  • Whether special drivers are required or it is “Windows only” is unclear.
  • AOC is typically “Windows only”; c.f. AOC E2251FWU 22″ DisplayLink USB Monitor


DashDAQ for Chevrolet Volt

Works With Linux?

  • Maybe
  • Unknown & unclear
  • Interfaces
    • USB
    • Serial
    • SD Card “to 32GB+”
  • Made of Linux cite, but unclear the access remains Linux-operable.

ZaReason Chimera vs Hewlett-Packard EliteBook 8770w

Via: ; Hands-on with $6,400 of workstation-class laptop; In Ars Technica; 2013-01-29.

I have a Chimera not an 8770w. Here are the issues I’d look for in the 8770w:

  • Runs Linux?  Maybe (as-declared: runs Windows 7)
  • Cooling; these things run very (very) hot
    • The boards are configured to shut off at 95C.
    • These are server-class processors with speed step
    • You can do short bursts, but not long grinding computes
  • The limiting factor on these things is always and ever video piping out to actual viewable display area. There are only two video outputs:
    1. The inboard panel at 1980×1080
    2. The outboard DisplayPort at 2550×1600 (max?)
  • Battery life: if you want battery life, get something else.  If you get these, you want speed, capacity, capability in an 8 lb container.


Via: ZaReason

Runs Linux: guaranteed

  • No longer available 2012-12.
  • 1920×1080 display inboard panel
  • nVidia GTX 485M or nVidia GTX 560M, 2GB GDDR5
  • i3 through i7 processors available.
  • base model $1800
  • “all the dials at 11″ model circa $6600.

Analysis & Commentary

Based on information and belief. There are keywords “for Macintosh” is some of the product titles, but “for PC” in others; the latter usually means “Windows lockin.”.  But there could still lockouts, drivers, application manager software(s) for both Windows and Mac cultures.  Little version numbers matter in these things; c.f. the experience with ReadyNAS; vast differences in hardware and software internals across products that differ slightly in their naming & wording.

Brock Tice cites Warning <quote>I started with a Mac model (S300M I think? no Windows drivers?) and then moved to a Windows model, the S1500.</quote>

  • There are Windows versions of these products
  • There are Mac versions of these products
  • They don’t play well together
  • Or maybe that has been fixed ref ref
  • Or maybe it hasn’t in older builds that are still on sale; who knows: <quote> the biggest headache of previous ScanSnaps (and there weren’t many) was the fact that they were not cross-platform.</quote> ref
  • Beware.


Notes & Issues

  1. No evidence that it does work on Linux; and plenty of evidence that Fujitsu does not support Linux
  2. In fact, the main use case for this product seems to be to route around the whole desktop culture lockin and work with iOS and Android tablet readers.
  3. But the installer/manager/controller/configurator application seems to be ensconsed MacOS-native culture.
  4. And it seems that the documents either must be received by the proprietary SnapConnect catcher or must must be shoved up into an open, unsafe, best-effort cloud service that will disgorge your documents to friends, enemies, governments and random scriptkiddies at the drop of but the nicest request. No mention of keeping your documents local and secure within the confines of your network. [TODO: find evidence to refute this]

It can scan front, back or duplex. It is however considerably bulkier and more expensive than the S1300; I like portability!</quote>
