Firstly, instead of a "basic graphics" mode, you can boot Ubuntu with the "nomodeset" kernel boot option added to your GRUB command line. See https://help.ubuntu.com/community/Grub2/Troubleshooting#Editing_the_GRUB_2_Menu_During_Boot
Secondly, I can boot and use Ubuntu 12.04 on a HP Compaq laptop with Radeon HD 6310 graphics (without using nomodeset), so it could be something to do with the kernel's detection/setup of your laptop's display panel. I don't suppose you know whether it is an eDP or not? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/997095 Title: Computer with Radeon HD 6310 boots up to black screen with 12.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-vesa/+bug/997095/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
