Description of problem: when a socks proxy is set, gnome freezes black screen, randomly without halting the system Version-Release number of selected component (if applicable): Fedora 24 4.7.6-200.fc24.x86_64 Please note: I'm inside a VirtualBox VM where Fedora is my Guest OS. I installed the VirtualBox Guest Additions ver 5.1.7-110797 I have configured the KVM acceleratetion. I have configured the VM network to Bridged Adapter. I'm using Snort in Fedora. How reproducible: happens randomly Steps to Reproduce: 1. Configure a socks proxy in NetworkManager Actual results: Randomly the screen freeze blank, although the system appears not halted but not possible to interact with it Expected results: Additional info: unset the sock proxy all run normally
I doubt it is NetworkManager issue. Rather it seems like a graphics-related problem, possibly related to the virtual machine. Would you describe in more detail how to reproduce the problem. And please capture some logs, like dmesg output and journalctl -b 0.
Unfortunately, in the meanwhile - I switched to Fedora 25 Host and Guest with QEMU/KVM, erasing Windows/Virtual Box - I haven't more details to add in the reproducing steps that I can remember. The black screen appeared only after set the socks proxy (I did a couple of tries to reproduce the prb). And my system was completely stable. I underline that I used socks proxies only.
I assume, you configured the proxy in gnome-control-center's network dialog. Note that NetworkManager is not involved with that. Since it seems no longer reproducible, I close this bug. Please re-open if additional information can be provided. Thanks.
