Getting 'Gah. Your tab just crashed' from Firefox running in WSL?

April 16, 2020|

Not all Linux GUI apps run in WSL. Some of them are having compatibility issues especially when they depend on background running services (ex. dbus) or require security related features in Linux. Recent versions of Firefox and many other web browsers are having such compatibility issues.

Unlike most regular Linux GUI apps that are developed for a specific task, web browsers can be a platform for running other programs (ex. web apps and plugins developed with JavaScript). Hence web browsers are trying to create a sandbox for safely running those codes and such techniques cause compatibility problems in WSL.

You can now seamlessly copy and paste an image between Windows and Linux GUI apps with X410

October 9, 2019|


X410 version 2.7.0 is submitted to Microsoft Store and should be available soon! Here are some of its highlights.

  • Just like plain text, you can now also share images (BMP/PNG) and HTML text between Windows and Linux GUI apps via clipboard.

    X410 natively recognizes and transfers raw image data in BMP and PNG formats. However, Windows and Linux automatically convert many image formats such as JPG to BMP format. Hence you should be able to freely copy and paste most images between the two OS's via X410.

    Please keep in mind that the clipboard sharing in X410 is utilizing network communication functions instead of system memories. So if your clipboard data is too big (ex. a high resolution BMP image) or your Linux app is running over a slow X11 forwarding, you may not be able to paste the data due to the delays and timeouts for synchronizing the two clipboards.

  • Keyboard layout files are updated to 'xkeyboard-config' version 2.27. You should no longer receive errors such as 'Error loading new keyboard description' while setting up your keyboard layout via 'setxkbmap'.
