We do rely on bug reporters to help with triaging the bugs they open. This is mostly because we do not have infinite resources to try and reproduce everyone's bugs ourselves. And doing so would be unreliable anyway, as we might hit slightly different issues and mistake them for the original issue. We have hundreds of bug reports to deal with each week -- there is not enough time to replicate them all.
Please follow the instructions in comment #2 as that will get this closer to a resolution. ** Changed in: compiz (Ubuntu) Status: New => Incomplete ** Changed in: nvidia-graphics-drivers-340 (Ubuntu) Status: New => Incomplete ** Changed in: unity (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to nvidia-graphics-drivers-340 in Ubuntu. https://bugs.launchpad.net/bugs/1853707 Title: Whole system stopped responding because of single program's fault - no way out, had to force power off Status in compiz package in Ubuntu: Incomplete Status in nvidia-graphics-drivers-340 package in Ubuntu: Incomplete Status in unity package in Ubuntu: Incomplete Bug description: What I did was: - install LibreCAD (by adding their ppa and then using apt-get) - open it - try to open the attached .dwf file LibreCAD hanged and the whole system stopped responding. The mouse button stopped moving, the system wouldn't respond to keyboard strokes, AND not even Ctrl+Alt+F1 worked to open a virtual terminal where I could have tried killing some process. Obviously there's a bug in LibreCAD, but no matter how badly a buggy (or even evil) process behaves, if a single misbehaving program can cause the whole OS to stall in a way that you cannot recover from, then by definition there's a bug in the OS. You must ALWAYS be able to kill the offending program and resume normal operation without having to stop one single application other than the offending one. I have no idea whether the bug is actually in Xorg or somewhere else; the reason I'm reporting it against xorg is that ctrl+alt+F1 wouldn't work. I might very well be wrong but I believe xorg is responsible for providing the virtual terminal via ctrl+alt+f1? Either way, that MUST ALWAYS be available no matter how badly things go. That a single program hanging causes me to have to force-power down the computer is outrageous.
