Comma splice on p.35

Rev. 788
Ch. 2, § "Desktop background", p. 35 (PDF p. 37)
Type: grammar

Manual has a comma splice (before "however"):
Here you will see Ubuntu’s default selection of backgrounds, however, if you have your own pictures stored on your computer
you can use these as well.

Suggestion for rewrite involving following sentences:
Here you will see Ubuntu’s default selection of backgrounds. To change the background simply click the picture
you would like to use. You're not limited to this selection though. To use one of your own pictures, click the Add... button, and navigate to the image you want.
