Re: [gentoo-user] Re: DRM Problem : Radeon HD 7670M

James,

Thanks for your response and suggestion !

Rich0's kernel crash dump page is interesting to me. I think that I could
find some useful information in it. I used Gentoo Live DVD to install
Gentoo into my laptop. I will use it to check VGA configuration again this
weekend.


Thank you !



Regards,
Phil
