Sapphire ATI Radeon HD 5450
Hi! I am looking to run a dual-boot Linux/Win7 machine that already has Windows 7 installed on it. I was going to go with Kubuntu because of Ubuntu's popularity and Kubuntu's (supposed) ease of desktop use. I consider myself to have novice to moderate technical skills (build my own PC, ran Linux and Google Chrome OS successfully from flash-drive, can do minor HTML programming, Savvy computing in Windows desktop environment).
My most recent budget build for a PC has:
ASRock Motherboard with onboard sound (no onboard video)
AMD Athlon II X3 at 2.9 GHz socket AM3 processor
8 GB DDR3 G-Skill Ripjaw RAM running Dual Channel
500 GB Seagate Barracude SATA 3 GB per second 7200 RPM HDD
Sapphire ATI Radeon HD 5450 Graphics Card with 512 MB Graphics Memory
I attempted to install Kubuntu onto this build and just got a blue screen after choosing "Install Kubuntu" from the live DVD which leads me to believe that Kubuntu 10.04 LTS Release doesn't support my graphics card. My monitor was hooked up using HDMI with a (when enabled) second desktop via SVGA. The HDMI said that it received no signal, the SVGA just showed the blue screen. It wasn't like a "blue screen of death" type of blue screen, rather, it was like the desktop background loaded with no splash screen, icons, or other GUI features.
My question (after taking the linux distro quiz which recommended Linux Mint) is which distro will support my hardware from the fresh install?
I posted on the Kubuntu forums, but I would prefer a LTS or stable edition of Linux over a beta edition. My reasoning is simple, I just need this as a backup OS so that in the event of a crash, computer virus, or other PC problem, before I re-install or fix or format or whatever I decide to do, I can go in and save files. I -do- keep backups, but I'd rather be prepared. I'd rather not have to go seeking bug fixes and other additional technical support for a backup OS that just lives in the background.
