This was a design decision made by the developers for Freya. There are some settings for Gala (the window manager in elementary OS) that control the corner masking. You can install dconf-editor (sudo apt-get install dconf-editor) to change the settings via a GUI, or use the built-in gsettings command from a terminal. You need to set the enable property to ...

It seems that as of now, elementary designs hot-corners to work like wingpanel and the dock and show them only on the primary display.

sudo add-apt-repository ppa:nilarimogard/webupd8
sudo apt-get update
sudo apt-get install caffeine-plus
It works fine on Freya.

Proper way to do it should be via System Settings -> Power -> Display brightness

Try adding nomodeset to the boot. Here's how to do it:
Press and hold the Shift button which will show you a GRUB screen containing a list of kernels and recovery options.
Press e to edit the appropriate kernel.
Add the word nomodeset before the words with quiet splash.
Press Crtl+X to boot.
NOTE: This will only add the nomodeset temporarily.

xrandr allows us to reconfigure the X server without restarting it. Let's use it to set the correct resolution at startup.
Find out how the monitors are identified on your system. At the terminal, run the following:
xrandr -q | grep ' connected ' | awk '{ print $1 }'
My output is:
LVDS1
VGA1
Now I want to narrow down the above results to only the LG ...

You could just open up the terminal and type this:
xset dpms force off
Once you press Enter to execute the command, it'll turn off your monitor instantly. This works with every X server. If you press a key or move a mouse, it goes back on (maybe you want to change a song or something). I'm using this method to listen to the music all of the time.

I just recreated the problem and was able to fix it by deleting the ~/.config/monitors.xml file.
Note that by deleting this file all settings for displays will be lost.
The file is in a hidden folder, so to be able to find it you need to make hidden folders visible in the file browser. To do this press Ctrl+H.

When launching Chromium web apps you can pass the flag --force-device-scale-factor=2 to get properly scaled content on HiDPI.
Ideally you should add it to the respective .desktop file of the app so that you can have the launcher in the dock or start it via Slingshot.
For example:
$ cat ~/.local/share/applicationschrome-f*-Default.desktop
#!/usr/bin/env ...

Unfortunately, this is something that has to be fixed by those app or toolkit developers. For example, Google Chrome only just recently started to support HiDPI. Most Gtk3 apps (like the ones we ship by default) should get HiDPI support more-or-less for free with only minor issues to work through. But since HiDPI is still relatively new, not all application ...

Quick answer to your second question.
You can drag a window by clicking anywhere inside of it with the combination Super + left click.

(This might be a bug, but on my system, Loki's Displays settings do not naturally let users stack screens atop each other, either with the secondary directly above the primary or vice versa, though I can futz around with it to make it work.)
Not being able to drag the window through the menu bar is likely by design—that would be a confusing scenario when ...

vmware-workstation works without problems with the root user, however, it is very annoying to open the terminal to open the program and believe that the icon is useless. I found a way to bypass the problem by clicking on the icon and the program open asking for root password without having to open the terminal.
First we should open the file that is in
/usr/...

Fortunately I seem to have ran into a solution for Elementary OS and felt it would be best to share it.
Open up the application launcher and search for Additional Drivers and select 'Using Video driver for the AMD graphics accelerators from fglrx-updates (proprietary)'.
After I rebooted my system, both monitors have been working and I've tested to ...

You need either dconf-editor or command-line tool gsettings.
You can change the value of net.launchpad.plank.enabled_docks to ['dock1','dock2'] in order to enable a second dock,
restart plank,

Nope, without custom scripting, the OS only supports switching between windows in a workspace ("Switch Windows" in Settings > Keyboard) and switching between workspaces (org.pantheon.desktop.gala.keybindings cycle-workspaces-next), but not apps across all workspaces.
What you can do, however, is set "Show All Windows" in Settings > Keyboard > ...

I was able to fix this by setting the correct primary monitor via LightDM.
LightDM is elementaryOS's lock screen (aka pantheon-greeter)
First you need to find the name for your primary monitor using the command xrandr. It will be something similar to "HDMI1" or "DVI-0".
Once you have the correct monitor name you will need to edit the file /etc/lightdm/...

Even though you've removed Redshift, it seems it has "permanently" altered your display settings. Try running:
xrandr --output eDP-1 --gamma 0.9:0.9:0.9
eDP-1 is the name of my monitor, yours may vary

This seems to be a bug in Gala, see issue Tracker.

default integrated monitor is not always LVDS-1
first you should get overview of detected displays and their aliases by command
xrandr | grep " connected " | awk '{ print$1 }'
then cast
xrandr --output <here alias of your integrated monitor> --off

This is a known issue in Elementary OS due to their somewhat non-standard way of applying window decorations. Fortunately, there is a fix, but it must be applied on a per-application basis. In fact on the issue description itself on GitHub, there's a summary of how to fix it with Eclipse as a sample:
For those wondering how to change the .desktop file ...

Hit the key combination Alt + F2 that will open your applications menu. Once it is open, you can type in the command you need (pantheon-terminal, or switchboard).

I had a similar issue, but instead a black screen, it hanged for a while and displayed almost all the frame as a corrupted image, all except the text box and buttons. So I believe this is a GPU problem and Ubuntu may be using a different driver.
For me, the solution was:
1 - In the Applications menu, search for Software & Updates
2 - go to the Drivers ...
