Fedora 15: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller

I get a black screen upon boot if inteldrmfb is enabled. So I needed to boot with the option "nomodeset". But with this option I could just use the vesa driver in Xorg.



One solution is:

1) Remove "nomodeset" and "vga" options from kernel boot parameters

2) Add this options to kernel parameters:

i915.modeset=1 video="inteldrmfb:1440x900"

3) Run setpci -s 00:02.0 F4.B=00 as root to turn the backlight back on. You can do this automatically on boot putting this command in /etc/rc.local



Now you can use intel driver in Xorg.
