If you mapped a shared folder to a drive letter like ‘G:’ and it is still not showing up in your windows guest, make sure you install the latest ‘virtualbox tools’ from the Virtualbox menu. You don’t have to uninstall the previous version. Also make sure networking is enabled and connected. You can create a host only adapter if you don’t want the machine to access internet over NAT, which will still show the shared folder. You can also access the network driver using ‘\\vboxsrv’.

I was trying to connect a USB Scanner to a Windows Guest OS running in Ubuntu, but there were no USB devices visible when I clicked on the USB icon in the tray. Turns out the host user needs to be added to vboxusers group using the following command:
sudo adduser $USER vboxusers

I took out the CD drive in my laptop and installed an SSD in its place, using a HDD caddy. Then I proceed to install Ubuntu on the second disk using default but it ended up installing Grub on first drive containing Windows. This is a deal breaker for me since don’t like to boot into Windows via Grub. I used Boot-repair to get did of Grub, by disconnecting the Linux SSD. https://help.ubuntu.com/community/Boot-Repair . Then reinstalled Ubuntu after connecting the second SSD, but this time I chose “Something Else” and selecting the Grub installation location as the second SSD ( /dev/sdb ) as shown here. https://help.ubuntu.com/community/Grub2/Installing
. I created only two partitions, one is 32GB swap since I have 32GB RAM, and the rest as ext4 root (/) . Now I have Grub menu only if I boot from second disk, and I can choose Windows if I want. If I boot from first disk, I boot directly into windows.

I ran into this issue while trying to open a Gradle project in IntelliJ 2018. The solution is to set the JVM again from the settings for Gradle as shown below. If that doesn’t work, close the IDE, blow up the settings directory of IntelliJ with
rm -fr ~/.IntelliJIdea2018.3/
Then reopen the project.

It used to be much easier back in 2012. You could just flash the e3000 latest version of DD-WRT. But now you need a trailed build as the latest version of e3000 are not compatible with old Linksys or DD-WRT firmware for e3000. The Wiki at https://wiki.dd-wrt.com/wiki/index.php/Linksys_E3000 is slightly confusing. Here is the simplified version:

Set the following option in xorg.conf.d
Option “TearFree” “true”
Detailed instructions:
sudo apt-get install driconf sudo mkdir /etc/X11/xorg.conf.d/ echo -e 'Section "Device" Identifier "Intel Graphics" Driver "intel" Option "TearFree" "true" Option "DRI" "3" Option "AccelMethod" "glamor" EndSection' | sudo tee /etc/X11/xorg.conf.d/20-intel.conf sudo reboot
Remove that file if you want to revert.

If you have video issues with Nvidia graphics, make sure you installed the Nvidia binary driver (proprietary driver). Linux Mint doesn’t install it by default and you will find the video and scrolling tearing the screen.

You can use the HTML pre tags around the code in the Text mode (aka the source mode).
public class HelloWorld { public static void main(String[] args) { // Prints "Hello, World" to the terminal window. System.out.println("Hello, World"); } }
You can use the WordPress code tag. You can read about that at https://en.support.wordpress.com/code/posting-source-code/
public class HelloWorld { public static void main(String[] args) { System.out.println("Hello, World"); } }

Since Chrome provides a Debian package, you can do:

That didn’t work since dpkg can’t install dependencies. So I tried using apt.
s@s-Lubuntu:~/Downloads$ sudo apt install ./google-chrome-stable_current_amd64.deb Reading package lists... Done Building dependency tree Reading state information... Done You might want to run 'apt --fix-broken install' to correct these.

Now using the –fix-broken option
