[solved] dell inspiron 7520 pre installation suggetions (?)
I just bought dell insp. 7520 and want to install arch(64bit) in it. I have arch installed (32bit) on my desktop .. but wondering if the whole switchable graphics (intel and ATI ) works or not ?!? I could work with only intel graphics though (as it would save a lot more bettery ...
then again I am preparing for RHCSA and would like to run two or three VMs so any heads up ??
any suggetions before i try ? Thanks in advance.
(this is my first laptop.. i have only used Desktop so far.. would miss the old simple days so much ! lol)

yes, perform a "standard" installation. then follow this wiki for hybrid/dual-graphics:
https://wiki.archlinux.org/index.php/Bumblebee
and for power-saving, these:
https://wiki.archlinux.org/index.php/Pm-utils
https://wiki.archlinux.org/index.php/Laptop
that's all for now!

oh, sorry, this is the right page:
https://wiki.archlinux.org/index.php/Hybrid_graphics
now: the hybrid package automatize the procedure described in the page.
my HOT suggestion is to follow the manual solution, not the automatic because the "hybrid-video-ati-intel" package isn't updated and.....isn't difficult

Re: [solved] dell inspiron 7520 pre installation suggetions (?)
oh i almost forgot .. i did this :
# echo > /etc/modprobe.d/radeon.conf blacklist\ radeon and loaded it in rc.local with - modprobe redeon
now i aslo added " echo OFF > /sys/kernel/debug/vgaswitcheroo/switch " line right after that ..
is that correct ?! or should i remove one of them ?

Re: [solved] dell inspiron 7520 pre installation suggetions (?)
i have no experience about dual-gpu....but seems right
the only way to know if it's right, is to try

Re: [solved] dell inspiron 7520 pre installation suggetions (?)
anyway i found the solution .. I just had to do a little bit of extra then the arch wiki told me .. here is my rc.local code
#!/bin/bash
#
# /etc/rc.local: Local multi-user start-up script.
#
sleep 1
modprobe radeon
sleep 2
echo ON > /sys/kernel/debug/vgaswitcheroo/switch
echo IGD > /sys/kernel/debug/vgaswitcheroo/switch
echo OFF > /sys/kernel/debug/vgaswitcheroo/switch then you need to black list radeon module. and for cpu frequency scalling i used laptop-mode-tools package. good luck if anybody is having the same problem as me..
