BT5r3 on Alienware m14x R2 - Problems with Intel HD4000 (Brightness + Resolution)

[WepWapWee]

How can I find out? I got 2 - Intel HD 4000 (Core i7 3630QM) and the NVIDIA GT650m - I would like to use the Intel for normal desktop if that is possible.
I also tried to install the xserver-xorg-video-intel driver from different ppa's.
But when the i915 driver is load (ex. via modprobe i915) my screen starts flickering with all colours.

The BIOS settings of your Alienware m14x laptop should have settings that allow you to control your VGA adapters.
I think the most straight-forward approach is to try to disable the Nvidia card from BIOS. This way you'll know for sure that Intel is used. So you'll focus on getting it to work nice.

I don't have the options in BIOS

Only R1s have that BIOS option. R2 and R3s are Optimus only.

Try installing the nvidia propietary driver. Perhaps the nvidia video card is the one being used. That's perhaps why the module is not loaded (i915)...

Also read the user's manual to see what card is being use by default or how the "Oh my god, here we go again", useless and so "problem issues" Optimus Tech works (at least in Linux)...

Can't fix a problem without knowing what you have in your machine and HOW it works..Don't you think?

Luck.

@maverik35:
which info I should provide? also tested to install the propietary but then optirun isn't working anymore.

I installed the driver from ppa:glasen/intel-driver

during startx the i915 is loaded normally (see /var/logs/Xorg.0.log)

but I have to connect an external screen via VGA to get a picture on screen. notebook still flickers

lsmod: (after startx)

Do I need maybe a /etc/X11/xorg.conf file to get the notebook display working??
