So you actually have the external ATI one, which you use, and the integrated one, which you do not use. Some laptops can switch between the two (performance/economy). It looks like your laptop model always uses the external one. What I'm saying is that, _maybe_, the internal one is not totally disabled and has still some memory allocated to it at the hardware/BIOS level. I may be totally wrong, but my idea comes from this site: http://www.anandtech.com/show/2955 which says: While the low clocks will reduce heat output and improve battery life for the Inspiron 15, it bears mentioning that there's no way to switch to using the integrated graphics built into the Core i5 CPU and thus improve battery life further. This is similar to what we saw with NVIDIA's switchable graphics, which have only been in a few products over the years. As we covered in our Optimus Technology Overview, switchable graphics requires more validation and testing, more motherboard layers, and several multiplexer chips (typically two per video output). Given all of the added work, it's perhaps not too surprising-though it is disappointing-that Dell chose to keep costs down on the Inspiron 15. Less expensive models are available with Intel HD Graphics, for those that don't need a faster GPU. > please have a look at the output[1] on "cat /var/log/dmesg" > > [1] http://cl1p.net/jk/ The good part is missing at the beginning of the log. Try "dmesg -s 500000" to capture the entire thing. -- Roberto Ragusa mail at robertoragusa.it -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
