Re: status of graphics switch support in vanilla kernels
Hello Fabrizio,
I have a Sony VPCZ13A7E running debian squeeze ..
I just compiled a 2.6.38-rc3 kernel from kernel.org ...
I don't have integrated the modified module from Adam (ie I have sony-laptop
0.6) and when I run lspci in stamina mode, I see only the Intel card !!
Does it mean that modifications have been put into the maintstream kernel ?
