I was satisfied with 13.04. But when I upgraded to 13.10, I've had a lot of issues and some things just no longer work.

To name a few problems:

• Can't change the brightness

• My laptop makes more noise than before

• It freezes more frequently (the kind that doesn't respond to ctr + alt + f2)

• Sometimes it boots up and and can't play any media files

• When running a full screened virtual machine in Workstation, ubuntu
  catches mouse at the edges When I have a VM opened in Workstation and I try to open up another, the first one gets powered off

• Most irritatingly, when I have a virtual machine running in full screen, every now and then the vm screen goes black and I have to switch to the host and come back

13.10 has offered nothing to compensate for these problems. I would like to get some advice about what I can do. Should I stick with 13.10 and hope the bugs will be fixed? Would a clean reinstall of 13.10 help? Btw, I'm giving some thought to trying other distros.
