As i wrote my problem some weeks ago, that Fedora 15 or any other linux version didn't run on my Laptop.I got two problems:-<br>1. My screen goes Black on booting Linux.<br>2.I got Intel error with following message<br>
> - Dropping to debug shell.<br>
> sh: can't access tty: job control turned off<br>
> dracut:/#<br>
><br><br> I can run any game or softwares on my system using windows. I'm possessed with Linux,but i can't use Linux on my system. <br> I have contacted Dell technical support for help regarding this problem. They told me that there will be no option in BIOS to disable one of my graphics card. So the problem remains same. They told me that nVIDIA is primary graphics card in my laptop & Intel HD3000 is secondary graphics card. And also as i'm using i-7 processor that support's some kind of architecture that has to use both of graphics card & i can't disable any of them. in short, they said that my laptop's hardware architecture supports only both card option & i can't disable any of them. But i don't believe them, there is no such architecture in which we can't disable one of the graphics card. Hardware manu. companies designs motherboard in such way that if one of graphics card fails (like let nVidia fails in most of the cases)then automatically it switches to inbuilt VGA (Intel HD 3000) or secondry vga. I'm not sure about my statement but i think so. <br>
<br>But if they are true, then this means any of linux distro can't support my hardware. So we have to design such kernel that supports all the hardwares & architectures. Can we design this kind of kernel? it doesn't matters what the problem is, may be it is nvidia's optimus drivers that they have not given to add in Linux kernel or any architecture problem that is not supported by Linux. the main thing is that Linux Doesn't have solution for both problem. It applies to all Distros. So can open source programmers design such kernel or not ? Or i haave to wait for next 10 years to use Linux on my Laptop.<br>
