Hi I'm experiencing a bug that makes working with my laptop a pain in the ***.
I'm using linux mint 12 with gnome 3. Kernel Version: 3.0.0-13-generic on an dell vostro 3550 laptop with intel core i7 and amd radeon hd 6600m (hybrid graphics)
Because I don't want to use the radeon card (too much power consumption i used this fix for hybrid graphics that turns off the radeon card and lets linux use the intel integrated card:
added "blacklist radeon" to /etc/modprobe.d/blacklist.conf
echo OFF > /sys/kernel/debug/vgaswitcheroo/switch
After I boot everything works fine for about 20-60 minutes then, without any good reason, my screen starts flickering when editing text or browsing or similar stuff. (How often depends on the stuff I do, if i use a text editor it's like once per second). The bad thing is that i loose mouse focus every time it flickers. If I want to mark some text it will stop marking it, if i right click to open any menu it will be closed before i can click on an item. It's very annoying.
Every time the screen flickers these lines are added to the Xorg.0.log:
[ 12867.010] (II) intel(0): EDID vendor "LGD", prod id 739
[ 12867.010] (II) intel(0): Printing DDC gathered Modelines:

I searched the web and asked in forums but there doesn't seem to be an easy solution to this. Most of the people say it's a driver issue, so I thought about upgrading the intel driver. The thing is that I'm kind of a linux noob and I don't want to mess things up if I compile the driver from source.
My questions are:
what should i do to fix it?
Do you think it's a driver issue and will be resolved by installing those intel drivers: http://intellinuxgraphics.org/2011Q4.html
How can I install them? I tried ./configure for the xf86-video-intel driver and it says:
configure: error: Package requirements (xorg-server >= 1.6 xproto fontsproto pixman-1 >= 0.16 ) were not met:
But xorg-server should be installed right?
Maybe it has something to do with the hybrid graphics stuff and the fix i used to turn of the radeon card?
