Hello. For some reason, the keyboard stops working after resuming from sleep mode in Google Chrome 57.0.2987.133 x64 in Xubuntu 16.04.
In all other applications, the keyboard works fine, the problem is cured by restarting the browser, but this is inconvenient, especially when many important tabs are open.
