My new laptop has an NVIDIA graphics card (not sure which one). I have freshly installed Fedora 27. However, I cannot get my HDMI or VGA port to work or even be recognized. I've tried following the instructions at https://www.if-not-true-then-false.com/2015/fedora-nvidia-guide/ and https://fedoraproject.org/wiki/Bumblebee (as well as a few others), but have been unsuccessful thus so far.
Here is some output from various commands for context:

It ended up being because I installed my OS in Basic Graphics Mode: https://ask.fedoraproject.org/en/question/46846/what-does-nomodeset-do/

We are experiencing performance problems with Stardog requests (about 500 000ms minimum to get an answer). We followed the Debian Based Systems installation described in the Stardog documentation and have a stardog service installed in our Ubutu VM.
Azure machine: Standard D4s v3 (4 virtual processors, 16 Gb memory)
Total amount of memory of the VM = 16 Gio of memory
We tested several JVM environment variables
Xms4g -Xmx4g -XX:MaxDirectMemorySize=8g
Xms8g -Xmx8g -XX:MaxDirectMemorySize=8g
We also tried to upgrade the VM with a machine but without success:
Azure: Standard D8s v3 - 8 virtual processors, 32 Gb memory
By doing the command: systemctl status stardog in the machine with 32Gio memory
we get :

Of all your queries the slowest took 8 minutes to complete while the others completed very quickly. Best to identify the slow query and profile it.
there are very similar questions to this one but all of them are solved by disabling some other wifi source by using modprobe and then reseting rfkill
in my case:
artixlinux:[rail]:/etc/modprobe.d$ rfkill list all
0: phy0: Wireless LAN
Soft blocked: no
Hard blocked: yes
and with nmcli:
wlan0: unavailable
"Qualcomm Atheros AR9485"
wifi (ath9k), 5A:9D:61:C0:BB:F0, sw disabled, hw, mtu 1500
I've already tried to modprobe ath9k but that does nothing

"Hard blocked" cannot be changed by software, look for a wifi toggle on your keyboard or edges of the laptop; the device can also be hard blocked if disabled in the bios.
And:

FYI hard block also happens when the wifi is disabled in the bios.
We have two hypervisor(Dell PowerEdge R630, virtualization environment: Proxmox), they are connected with an FC-switch and the FC-switch with the storage(dell compellent).
One of the hypervisor are connected via multipath to the storage and it's works.
The other hypervisor doesn't found the storage.
The not-finder-hypervisor says:

The multipath module is loaded into kernel. Both hypervisor have the same loaded modules.

Check SAN-zoning and LUN-secuty on the array: they must define and allow host-connection with the array and LUNs on it.
I am using an Orange Pi PC PLUS2 (emmc memory, arv7l 32bit) for controlling another device through a serial connection (RS485) with a serial converter that uses FTDI chips (sparkfun bob 09822).
I am using docker containers and docker-compose to embed my application and easily deploy/share it. It doesn't do anything too complex, just reads continuously (1 per half second) values from sensors through the rs485, stores it in a local db and sends data to my server.
uname -a gives me:
Linux host-test 4.14.15-sunxi #28 SMP Mon Jan 29 07:24:48 CET 2018 armv7l GNU/Linux
If I run my SW outside docker, everything is working fine, I don't experience any crash after weeks. Problem is that if I use docker, within a couple of days I get the following error (dmesg):
[135431.500807] ftdi_sio ttyUSB0: ftdi_set_termios urb failed to set baudrate
[137213.011801] ftdi_sio ttyUSB0: ftdi_set_termios urb failed to set baudrate

[140560.099738] ftdi_sio 6-1:1.0: device disconnected
After that I can't use the serial converter anymore. It does not appear on ttyUSB0 and I don't manage to make it work again. I tried to rmmod both "ftdi_sio" and "usbserial" and modprobe them again, but nothing changes. The only way to fix it is to reboot the board.
I am experimenting a lot with modules like pylibftdi, vpc drivers vs d2xx ones, etc...without luck.
I also use the same SW on a Nanopi NEO PLUS2 (emmc, armv8 64bit, Linux host-test 4.14.0 #82 SMP Fri Dec 8 14:33:14 CST 2017 aarch64 aarch64 aarch64 GNU/Linux) and I have an identical issues...all ok without docker, similar issue happens when using docker (slightly different dmesg).
My docker-compose is nothing special, it just maps the serial port with "devices: - /dev/ttyUSB0:/dev/ttyUSB0"
Question
Does anyone have a clue on how to solve this big problem that is completely stalling my work?
Extra (quick and dirty)
At least, just as a temporary patch, does anyone have any idea how to restore the serial line without rebooting and wants to provide me a hint on the comments?
Edit
For the sake of completeness, here is the error (dmesg) in the Nanopi:

Updated my xcode this evening to 7.2.1 im running on yosemite 10.10.5
i've just started learning swift, and everytime i try to run the simulator it crashes with the error:
could not load inserted library '/usr/lib/libignitor2.dylib' because no suitable image found.
I have spent the last 4 hours searching online, there seems to be a few similar errors of inserted library missing but nothing that i can see that helps with this error. The full code can be seen below.

You could try
sudo update_dyld_shared_cache -force
I'm trying to fix my beta but it appears to be trying to get after an update and this is the solution I"m working with. If it fails you can try
