It happens a strange thing:
I'm trying many packages to fit the distro to my needs and installing/removing packages mess the sistem up. Before Xorg, brasero wouldn't start. Switching to Xorg fixed the problem, but I had a very slow page scrolling in documents reading, in firefox or windows resizing, and turned back to Xvesa. Brasero continued to work thereafter.
Maybe is not a bug but just my hands that do bad
anyway thanks for reading me.
