EDIT: Using VGAswitcheroo is NOT possible because it's accessible only if the radeon module loads. But my whole problem is that the radeon card doesn't load, if Ubuntu tries to load it, it hangs.
My HP DV6 6121tx's AMD card has developed some kind of strange hardware fault. So I'm running running Windows with only the Intel drivers, and the AMD card disabled. It runs well enough, I'm not having any issues (except of course I can't run high res games, but that's not a problem).
Now I really need a working Ubuntu installation on my computer, but I cannot figure out how to achieve the same with it.
Right after I install Ubuntu (no modifications), and I boot it, I get this screen.
If I use nomodeset in the boot options, Ubuntu boots up properly, but in 'Software Rendering Mode'. I've tried various other boot options including:
i915.modeset=0 i915.i915_enable_rc6=1 video=1366x768-24@60 video=VGA-1:1366x768-24@60
Can you guys guide me on how to disable/ignore/blacklist/uninstall the AMD Card from Ubuntu and use Intel Graphics ONLY in Ubuntu; like I'm using in Windows?
There's no option in my BIOS to disable the AMD card.
(I've marked it as urgent because being a Computer Science student, most of my coursework is Linux based)
Thanks a lot guys, I'll really appreciate if you guys can help me solve this huge headache.
