Let’s dive into the details and get you up and running with this professional-grade trading platform.

Understanding Thinkorswim Requirements on Linux

Before jumping into the installation process, it’s important to understand the specific requirements for running Thinkorswim on Linux systems, particularly Fedora 42.

Thinkorswim is primarily a Java-based application that requires specific Java runtime environments to function properly. While the official documentation recommends Azul’s Zulu OpenJDK, users have successfully run the platform with standard OpenJDK versions available in the Fedora repositories.

Hardware Requirements:

• Modern processor (Intel Core i5/i7 or AMD equivalent)
• Minimum 8GB RAM (16GB or more recommended for optimal performance)
• At least 4GB free disk space
• Graphics card with decent performance for chart rendering

Software Requirements:

• Fedora 42 (though these instructions may work for other recent Fedora versions)
• Java runtime environment (Zulu OpenJDK 11 or 21 recommended)
• Internet connection for downloading and updates

The key difference when installing on Fedora versus Windows is the Java requirement. Thinkorswim requires specific Java versions, and recent user experiences suggest that either Zulu OpenJDK 11/21 or the standard OpenJDK 11/17 from Fedora repositories can work.

Prerequisites for Installation

Before beginning the installation process, ensure your system is properly prepared with all necessary components.

Check Your Fedora Version:

cat /etc/fedora-release

Ensure you’re running Fedora 42. If you’re using an older version, consider updating your system first.

Update Your System:

sudo dnf update

This ensures you have the latest packages and security updates installed.

Install Required Dependencies:
Thinkorswim may require additional packages for proper functionality:

sudo dnf install curl wget gnupg ca-certificates

These tools will help with downloading and verifying the installer and Java packages.

Understanding Java Options:
Thinkorswim officially recommends Azul’s Zulu OpenJDK, but users have reported success with standard OpenJDK packages as well. You have several options:

1. Zulu OpenJDK 11 (officially recommended)
2. Zulu OpenJDK 21 (newer option that works well)
3. Standard OpenJDK 11 from Fedora repositories
4. Standard OpenJDK 17 from Fedora repositories

For beginners to Linux, the terminal commands might seem intimidating, but they’re quite straightforward once you understand their purpose. Each command performs a specific action that’s necessary for the installation process.

Step 1: Installing the Required Java Version

The most critical component for running Thinkorswim on Fedora 42 is installing the correct Java version. While Thinkorswim’s official documentation recommends Zulu OpenJDK, recent user experiences have shown that standard OpenJDK packages can also work effectively.

Option 1: Installing Zulu OpenJDK (Officially Recommended)

There are two approaches to installing Zulu OpenJDK on Fedora 42:

Method A: Using the Azul Repository:

First, add the Azul repository to your system:

sudo dnf install -y https://cdn.azul.com/zulu/bin/zulu-repo-1.0.0-1.noarch.rpm

Then, install Zulu OpenJDK 11:

sudo dnf install zulu11-jdk

Alternatively, you can install Zulu OpenJDK 21:

sudo dnf install zulu21-jdk

Method B: Using the apt Repository Method (Alternative):

If the first method doesn’t work, you can try the approach mentioned in the official documentation, adapted for Fedora:

sudo dnf install gnupg ca-certificates curl
curl -s https://repos.azul.com/azul-repo.key | sudo gpg --dearmor -o /usr/share/keyrings/azul.gpg
echo "deb [signed-by=/usr/share/keyrings/azul.gpg] https://repos.azul.com/zulu/deb stable main" | sudo tee /etc/apt/sources.list.d/zulu.list

Note that this approach uses apt repository syntax, which might need adaptation for dnf on Fedora.

Option 2: Installing Standard OpenJDK from Fedora Repositories

Some users have reported success with standard OpenJDK packages:

For OpenJDK 11:

sudo dnf install java-11-openjdk

For OpenJDK 17:

sudo dnf install java-17-openjdk

Configuring Java Alternatives

After installing the Java version of your choice, you need to configure your system to use it as the default:

sudo alternatives --config java

This command will show a list of installed Java versions. Select the number corresponding to the Java version you want to use for Thinkorswim.

Verifying Java Installation

To ensure the correct Java version is being used, check the current version:

java --version

The output should display the Java version you selected, such as OpenJDK 11 or Zulu OpenJDK 21.

Step 2: Downloading the Thinkorswim Installer

Once the Java environment is properly set up, the next step is to download the Thinkorswim installer.

Official Source

The recommended way to download Thinkorswim is directly from the official Schwab website:

1. Visit the thinkorswim website and log in to your Schwab account
2. Navigate to the download section
3. Download the Linux installer (.sh file)

Command-Line Download Method

Alternatively, you can use wget to download the installer directly from the command line:

wget https://mediaserver.thinkorswim.com/installer/InstFiles/thinkorswim_installer.sh

Making the Installer Executable

After downloading, you need to make the installer executable:

chmod +x thinkorswim_installer.sh

This command grants execution permissions to the installer script, allowing you to run it.

Step 3: Running the Installer

With the installer downloaded and made executable, you’re ready to run the installation process.

Executing the Installation Script

You can run the installer using:

./thinkorswim_installer.sh

or

bash thinkorswim_installer.sh

Navigating the Installation Wizard

The installer will launch a graphical wizard that walks you through the installation process. Follow these steps:

1. Read and accept the license agreement
2. Choose the installation location (default is typically in your home directory)
3. Select additional components if prompted
4. Click “Install” to begin the installation process

The wizard is intuitive and similar to installation processes on other operating systems. The default options are suitable for most users.

Completing the Initial Setup

After installation completes:

1. Launch Thinkorswim

3. Follow the prompts to complete the initial setup
4. Allow any updates to download and install

The first launch may take longer as the application downloads additional components and market data.

Step 4: Configuring Wayland vs. Xorg

One significant issue that affects Thinkorswim on Fedora 42 is compatibility with display servers. Many users have reported problems with Thinkorswim on Wayland (Fedora’s default display server).

Understanding Display Server Differences

Wayland is the newer display server protocol that has become the default in Fedora, while Xorg is the traditional display server that has been used for decades.

While Wayland offers security and architectural improvements, some applications like Thinkorswim may not be fully compatible with it yet.

Switching to Xorg for Better Compatibility

To avoid display issues, many users recommend switching to Xorg:

1. Log out of your current session
2. On the login screen, click the gear icon (⚙️) in the bottom right corner
3. Select “GNOME on Xorg” instead of the default “GNOME”
4. Log in normally

This change will use Xorg instead of Wayland for your desktop session, which often resolves display problems with Thinkorswim.

Testing Your Configuration

After logging in with Xorg, launch Thinkorswim and verify that:

• The application window displays correctly
• Charts and data render properly
• No unusual graphical glitches occur

If problems persist, there may be other issues to address, which we’ll cover in the troubleshooting section.
