switch VGA controller

Hello, first of all, Id like to apologize if I'm asking stupid question, but I am very new to linux.

My question is, I encountered this problem (flickering screen on VGA output of my dell notebook):
https://bugs.freedesktop.org/show_bug.cgi?id=28306

but thing is if I exec lspci

Code:
# lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation Core Processor Integrated
Graphics Controller (rev 18)
01:00.0 VGA compatible controller: nVidia Corporation GT218 [GeForce 310M] (rev
a2)
There are two controllers. So how do I know which controller is used for external monitor ? Maybe if I switch it it would fix the problem? Or am I completely wrong ?

You will find a line like ths in the output of "lsmod"
video 13188 1 i915

So my system is using th i915 driver for the intel GPU. For the nvidea you might get
video 13188 1 nouveau
or similar.

You can probably control which is used from the BIOS.

Re: F14, F13 & F12 Nvidia driver guides

Even when I install it exactly accordingly to tutorial It hangs out after "Starting atd:". I tried kmod, akmod.
I can get into other terminals though. My lsmod displays nvidia in i2c_core, and there is no nouveau. Any ideas ?

Re: switch VGA controller

I have both i915 and nouveau there.

I've read that the flickering bug happens on i915, so I want to enforce my all my vga to be rendered by my Geforce 310M. Is it possible ? That would maybe help me with problem.

Re: switch VGA controller

1/ BIOS ?

2/ You can probably blacklist the i915 drver like
siu -
<passwd>
echo "blacklist i915" >> /etc/modprobe.d/blacklist.conf
^D

reboot

Re: switch VGA controller

1/ There's no such option in bios.
2/ I added blacklist i915 to the end of blacklist.conf file but it is still listed in lsmod.

Try running

Code:
su
cp /etc/X11/xorg.conf /etc/X11/xorg.conf.backup
nvidia-xconfig
It looks like the monitor isn't being detected.

Tried, still no help - still system hangs at startup (I can only switch to other terminal).

By the way maybe this could help ? I have no idea though.
Code:
# lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation Core Processor Integrated
Graphics Controller (rev 18)
01:00.0 VGA compatible controller: nVidia Corporation GT218 [GeForce 310M] (rev
a2)

You need to disable the intel card if possible in the mobo bios.

Hi, I can't disable in in bios because:
1/ There is no such option.
2/ I dual boot with windows, and I'd like to have it there (I guess)

I tried to disable it by appending "blacklist i915" >> /etc/modprobe.d/blacklist.conf , but it still is in my lsmod.
So is there some other way how to disable it, or have I done something wrong ?

I have very good reason why I am installing proprietary drivers, I have bug with external monitor flickering on VGA output and I'm hoping this would fix it.

Hi, I tried to disable it by adding to grub:
agp=off
now when I write 'lsmod'
in 'video' there is nothing (not even i915, not noveau). Maybe there should be nvidia ?

Before installing akmod
lsmod
Code:
video 21637 2 i915, nouveau
After installing akmod
lsmod
Code:
video 21637 1 i915
After adding the agp=off to grub
lsmod
Code:
video 21637 0
Maybe that helps ?

Re: switch VGA controller

I use Dell Vostro 3300, I believe it has no Optimus technology implemented, so I should be able to switch between GFX... or not ?

Edit: Thanks for merge. I'm new to this forum wasn't sure whether to post it as separate issues or no, and where to post it.
