use the Dell supplied Linux graphics driver for your machine?

i’m pretty sure they provide a graphics driver for Win7, right?

so, they must also provide one for Linux…oh wait! i just did this
google: http://tinyurl.com/6ejczyr and find
http://preview.tinyurl.com/62e9jon where i read:

As with other n-Series products, Dell hasn’t tested any particular Linux
distribution and doesn’t offer software support for running Linux on
these, so we encourage you to join our Linux mailing lists and to use
the one of your chosen distribution for community-based support.

so, no driver from Dell and i guess you won’t find every single feature
of the graphics driver replicated in the open source driver…BUT, i
urge you to join the appropriate Dell group here
https://lists.us.dell.com/mailman/listinfo
where you might find a good answer…

not to mean that you are not VERY welcome to hang out here and see if a
Dell n-Series owner running openSUSE has independently discovered how to
do what you want to do

for next time: if you want a laptop known to work with Linux, buy one
with Linux installed by the factory–Dell sells those also (but, they it
might not run Windows)

Please give us the output from


/sbin/lspci | grep VGA
hwinfo --gfxcard

to see your graphics card model, maybe you need a better driver than what
you have now.
