Describe the Bug
When running Cursor IDE (cursor.AppImage, version 1.0.0) inside an Ubuntu 24.04 VirtualBox VM, the IDE frequently becomes slow, unresponsive, or crashes. The integrated terminal (ptyHost) fails after a few seconds, and multiple processes crash unexpectedly. This occurs even after applying all recommended flags and mitigations. The same environment runs VS Code without issues.
Terminal and logs show repeated errors like:
No ptyHost heartbeat after 6 seconds
ptyHost terminated unexpectedly with code 2
Extension host crashed with code 2 and reason ‘killed’
Steps to Reproduce
Set up Ubuntu 24.04 in VirtualBox (with Guest Additions, 32 GB RAM, 4 vCPUs, 128 MB video memory, Xorg session)
Download and make executable the latest Cursor AppImage (version 1.0.0)
Launch with:
~/Applications/cursor.AppImage --no-sandbox --disable-gpu
Wait ~10–30 seconds or attempt to use the integrated terminal
Observe freezes, lack of terminal response, and eventual log entries indicating ptyHost failure
Expected Behavior
Cursor IDE should operate smoothly inside a supported Linux environment, with responsive terminal access and functioning extensions. Processes like ptyHost, extensionHost, and shared-process should not crash under normal conditions.
