--- Comment #10 from Alexander Mezin (mezin.alexander@gmail.com) --- Actually, sometimes mouse pointer moves, and only freezes after I press a few keys/click a few times. Also, sometimes it's just colored pattern instead of the lock screen on the background. With Gnome on Wayland it takes a bit more time to break: after resume I see the desktop, but after a few clicks/key presses I see artifacts and then eventually everything freezes.
And just in case: - The problem also occurs with only one monitor connected. - On Windows on the same machine suspend and resume works without any problems.
