3 Common Errors with Possible Solutions
While using Tmux, you may encounter some common errors. Reading and understanding the error message is helpful in finding the best solution. Here are three frequent errors and their possible solutions:
- 🔄 “Scrolling is not working in Tmux” error: If you find that scrolling is not functioning as expected in Tmux, it is likely due to improper configuration or lack of support for scrolling in your Tmux setup. Review your Tmux configuration file
(~/.tmux.conf)for any conflicting settings or key bindings that may affect scrolling to resolve this issue. Additionally, ensure that mouse support is enabled in your terminal emulator and the Tmux configuration. If you use a Tmux plugin for scrolling, ensure it is correctly installed and configured.
- 📜 “Scrollback buffer limit reached” error: Tmux limits the number of lines stored in the scrollback buffer. When this limit is reached, you may encounter errors or truncated output. To address this, you can increase the scrollback buffer size by modifying your Tmux configuration file
(~/.tmux.conf). Add the line
set-option -g history-limit <number_of_lines>, replacing
<number_of_lines>with the desired value.
- ⚡ “Scrolling is choppy or slow in Tmux” error: If you experience choppy or slow scrolling in Tmux, it could be due to performance issues or insufficient system resources. Start by checking if any resource-intensive processes run concurrently and utilize significant CPU or memory. Optimizing your Tmux configuration can also help improve scrolling performance. Consider disabling unnecessary plugins or simplifying your Tmux setup. If your terminal emulator supports it, you can adjust the scroll speed in Tmux by adding the line
set-option -g mouse-scroll-speed <value>to your
~/.tmux.conffile. Experiment with different values to find an optimal scrolling speed that suits your needs.

Frequently Asked Questions
Is it possible to scroll through the Tmux scrollback buffer indefinitely?
By default, Tmux has a limit on the number of lines stored in the scrollback buffer. However, you can configure Tmux to increase this limit or set it to an unlimited value. In your Tmux configuration file
(~/.tmux.conf), you can add the line
set-option -g history-limit <number_of_lines> to adjust the buffer size. Replace
<number_of_lines> with the desired value or set it to unlimited to scroll through the buffer indefinitely. Keep in mind that setting an excessively large buffer size may consume more memory, so consider your system resources when modifying this setting.
Are there any plugins specifically designed to improve scrolling in Tmux?
Yes, several Tmux plugins are available designed to enhance scrolling functionality and provide additional features. One such plugin is
tmux-scroll-copy-mode, which allows you to scroll through the scrollback buffer more smoothly. This plugin provides a more seamless scrolling experience, allowing you to scroll continuously without entering copy mode. Another useful plugin is
tmux-resurrect, which not only preserves your Tmux sessions but also saves and restores the scrollback buffer, so you can access previously scrolled content even after detaching and reattaching to sessions. You can explore these plugins and more on GitHub or other Tmux plugin managers like Tmux Plugin Manager (TPM) to find ones that suit your needs.
Can Tmux be configured to scroll to the bottom of the scrollback buffer automatically?
Yes, it is possible to configure Tmux to automatically scroll to the bottom of the scrollback buffer when new output is generated. To achieve this, you can add the line
set-option -g aggressive-resize to your Tmux configuration file
(~/.tmux.conf). This setting enables Tmux to adjust the window size to fit new content, ensuring that the latest output is always visible at the bottom of the scrollback buffer. With this configuration, you won’t have to scroll down each time new content is added, providing a more convenient scrolling experience manually.
