minicom or openocd command won't run without root permission on a Ubuntu 16.04 system.
这个问题是昨天注意到的，直到那时我才不必使用root权限。
Recent changes to system:
3-4 days ago my display would blackout after few seconds. While debugging the issue I installed/reinstalled a few drivers like lightdm, libpam-kwallet5, libpam-kwallet4, ppa:graphics-driver/ppa, ubuntu-desktop. Eventually, it was a hardware problem and I replaced the monitor. I believe I undid the changes to libraries. Also, I was connected to the system using ssh while running above commands.
I verified that current user exist in dialout and plugdev groups. Also I don't know if it matters but since this looks like a USB issue, I have three USB dongles - Wi-Fi, Bluetooth and Logitech Unifying receiver connected.
有什么想法吗？
