I can't login to desktop because I can't switch language on login screen.
I use two layote - English and Russian. On login screen Deepin 15.5 not switch keyboard layot by pressing Alt+Shit(I use this keys).
This problem is old for me. I click icon on login screen and choose english layote by mouse click. Allways.
After some updates this button stop to work. I can't switch language to enter my password.
One more problem: If I reload or turn off PC with russian keyboard enabled, after start PC have russian keyboard enabled.
It's not switch to English by default. This is the root of the problem!
