[ SOLVED] new kernel 4. 7. 0-desktop-0. RC7. 6. mga6 bugged

Hello ,
If I try to run the update 4. 7. 0-desktop-0. RC7. 6. mga6 (after choosing -4. 7. 0-desktop-0. RC7. 6. mga6) MGA shows me a gray screen with in the center three question marks and then I have a message that says there was a graphic display problem. After several attempts to regain control, I finally access the console. The screen displayed a message asking to type drakx11, and choose a mode and then type systemconfigctl default;
I then arrived on the login screen, but with US keyboard ,. . etc.
I returned to the previous version 7. 7. 0-desktop. rc 7. 5 it works well on the 1 shot!
but if it can help here. . . . .
