Comment 13 for bug 38323

The same phenomenon. FN keys does not have a function.
The Splashscreen has only 8-bit RGB. Sometimes the screen remains black after the Login.
Sometimes the screen is completely multicolored (8cololors) and the writing is no longer readable. In Breezy was all still ok. But now with Dapper I have only problems. Also it falls suddenly.
