I confirm that this still occurs with gnome-terminal and mate-terminal in Ubuntu 13.10. Same behaviour. Virtual terminals randomly freeze output.
Note: this does not necessarily need to be long running. The behaviour is random and can arise in a few minutes (10 minutes today) or a few hours (6 hours) a few days ago. The common characteristic seems to be text output to the virtual terminal. The terminal freezes output (that is the window stays live as do all the menus) but the output just stops. Clicking the window or using menu...reset resumes output. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-terminal in Ubuntu. https://bugs.launchpad.net/bugs/1234453 Title: Terminal freezes during long-running applications Status in “gnome-terminal” package in Ubuntu: New Bug description: What Was Expected: Virtual Terminal would simply display output until program terminated or ended. What Happens: When running an application in terminal, either as a launcher or simply opening a virtual terminal directly , the screen output randomly freezes and the generating running application freezes. To resume, one must double-click the open terminal window and/or use terminal reset & clear. The problem makes running almost any application with terminal screen output unusable--for example, running a machine learning algorithm. The problem affects both mate-terminal and gnome-terminal. The bug does not affect a simple x-terminal instance. Affected Applications: gnome-terminal mate-terminal but not xterminal. Test Code: The following simple Python3 code demonstrates the issue. import time starttime = time.time() i = 0 while(True): i = i + 1 print("Still working " , i, " " , time.time() - starttime) When running this code in a mate-terminal or gnome-terminal instance, the code displays a simple message along with the time. After a random period, sometimes seconds, sometimes minutes, the bug arises when the terminal instance screen simply freezes. That is, display output just stops in mid-stream. You can resume but only by double-clicking or using reset & clear. The bug affects at least Python and Java applications with output displaying to the terminal. Approximate Number of Tests: Over 50 and narrowed the issue to the terminal instances.
