Red Hat on Hyper-V - My CDROM doesn't work anymore!

I was doing some testing with Red Hat Enterprise Linux and didn't want to install it on physical hardware as I didn't have any available at the time.  After installing the OS, I decided to install the Hyper-V Integration tools so that I could have access to the NIC.  After getting it installed and rebooting, the CDRom is gone.  It's not that I can't mount it, the actual device is gone.  I did some searching and apparently, this is a known issue by Microsoft.  They have http://support.microsoft.com/kb/2600152 available for this issue as a workaround.  I created a shell script to do this and have it run at boot so I don't have to worry about it again.

Kali Linux Turning The Screen Off "Turn Screen off when inactive for"

Today I installed Kali Linux 1.1.0a and was really frustrated with the fact that you can't completely disable the option for the screen to turn off.  When you go to Applications->System Tools->Preferences->System Settings->Brightness and Lock, the maximum amount of time is 1 hour and no "Never" option.

I tried multiple things, but nothing would work.  After some digging I was able to find the file /usr/share/gnome-control-center/ui/screen.ui.  By adding the option here, we are able to select never, and it works!

Open the file with your favorite editor.  For simplicity, I will suggest using nano.

nano /usr/share/gnome-control-center/ui/screen.ui

Locate the following line (It is located in 2 different places in the file.  Use the second one, around line 83):

<row>

<col id="0" translatable="yes">1 hour</col>

<col id="1">3600</col>

</row>

Add the following:

<row>

<col id="0" translatable="yes">Never</col>

<col id="1">0</col>

</row>

Once you close and save the file, open Brightness and Lock and Never will now be an option.  This will now prevent the screen from turning off. 

The only issue with doing it this way is if you close Brightness and Lock again, it will default to 1 minute.  However, after going back into Brightness and Lock with 1 defaulted, it will not take effect unless you make a change and exit.

Of course I just found http://blog.tordeu.com/?p=292 which has really good informtion on how to do this correctly.
