I just successfully triple booted my HP Pavillion (dv6149us).
At 1st it was just Vista, then i installed iDeneb 10.5.5 (Hackintosh) and just yesterday, I installed Ubuntu 8.10 (yataaa!!!)… after 4 times of partition and 3 times installation and resintallation of ubuntu… it finally worked… but my dafault bootloader now is GRUB… i kinda liked Darwin (from OSX86) better… but hey, what works well is good enough, than “not” working at all…
Anyway, just this morning, I enabled Compiz (Beryl)… on my Linux boot… and i was surprised how easily I installed it… unlike from the previous versions… and unlike my MacOSX86… most of the drivers in my laptop, worked perfect (esp the most important ones)…
Maybe sometime, I’ll try and write a tutorial on how i did the installation(s).
