Like #143 and #146 with model 1000,  HP TouchSmart tm2 with switchable
graphics. But for the model 1050ef instead of 1000.

$ sudo dmidecode -s system-product-name
HP TouchSmart tm2 Notebook PC
$ sudo dmidecode -s system-version
049E100000200800000120000
$ lspci -vnnn|perl -lne 'print if /^\d+\:.+(\[\S+\:\S+\])/' |grep VGA
00:02.0 VGA compatible controller [0300]: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller [8086:2a42] (rev 07) 
01:00.0 VGA compatible controller [0300]: ATI Technologies Inc M93 [Mobility Radeon HD 4500 Series] [1002:9555] (rev ff) (prog-if ff)

P.S. Disabling the monster-card (ATI) change the battery life from 3H30
to 6H00 ! You should install the small module in next ubuntu if dual
graphics don't works. see http://linux-hybrid-graphics.blogspot.com/ for
more details.
