there's no proper display in ubuntu 13.04. i kinda removed a couple of animation settings in compizcongig but after experiencing problems with the launcher, i reverted them. then the launcher and top bar disappeared so i had to do a hard reset. when i booted back again, it tried to boot in failsafe graphics mode but that failed too. any help please? i can use the terminal and recovery options. i also have linux mint 14 installed if thats any help.
