Comment 195 for bug 752542

Dell Inspiron N5110

Sandy Bridge Core i3 + AMD Radeon HD 6470M

acpi_call (http://github.com/mkottman/acpi_call.git) works fine (both on and off) with echo "\_SB.PCI0.PEG0.PEGP._OFF" > /proc/acpi/call

echo OFF > /sys/kernel/debug/vgaswitcheroo/switch also works but the opensource radeon driver has a bug (https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/727620) and sometimes prevents kernel from booting when loaded so the radeon module has to be blacklisted

I didn't try the proprietary Radeon driver because I didn't need the Radeon card under Linux so far.

The HDMI Port (also sound) works on this model with the Intel driver though as far as I know it doesn't work on the Nvidia version of this laptop.

If there are further questions or requirement for testing I'm ready to help.
