Fedora 17 on Dell XPS 15 (L502X)
Dell XPS 15 (L502X) – by default comes with discrete nVidia card and i5/i7 processor to use nVidia Optimus technology to improve battery life. On Windows 7 it’s not an issue, Linux is different story.
So to enable this technology on Dell XPS 15 (L502X) I went with bumblebee project which improved battery life on my laptop.
Installation of Fedora 17 is not rocket surgery so only modification I recommend is to remove lv_home logical volume and use free disk space increase lv_root.
Second recommendation, which I highly recommend is to install freetype form infinality repo to enable anti-aliasing.
i) install repo by running this rpm -Uvh http://www.infinality.net/fedora/linux/infinality-repo-1.0-1.noarch.rpm
ii) yum -y install freetype-infinality
I highly recommend to reboot after this
And final step is installing bumblebee
i) install repo rpm
ii) and finally necessary binaries
yum -y install bbswitch bumblebee
iii) add user(s) to bumbleebee group
/usr/sbin/usermod -a -G bumblebee <USER>
After installation you must reboot to make necessary system changes effect.
After reboot run optirun glxgears to test bumblebee.
PS. This method does not require nVidia proprietary drivers.
