view story

http://ubuntuforums.org – i love both ubuntu and openSUSE, So i tried to install them in one machine. in first attempt i first installed openSUSE 12.2 and then installed ubuntu 12.04 alongside it in another partition. after this, i lose openSUSE boot splash. i thought it is because ubuntu 12.04 uses grub 1.99 and openSUSE 12.2 uses grub 2 so in second attempt i installed again both of them. this time i first installed ubuntu (because it uses grub 1.99) and then installed opensuse. every thing is ok about grub and boot splash for both distros BUT: ubuntu is ok but when i want to boot openSUSE its splash is ok but whe (Hardware)
