Silence of the fan

I don't have BIOS -- the firmware in my T520 is UEFI. UEFI firmwares provide configuration menus very much like BIOS.

(Yes, I'm aware that I'm being pedantic here. )

No, not pedantic. Well. I don't have UEFI firmware on my laptop and my bois doesn't have any settings for grafic cards to choose from.

So far my 13.10 install is nice and quiet. I am just noticing a delay when I boot into the desktop. My folder view widgets take ages to fill up and kwin generally feels a bit slower than on the 13.04 install (KDE 4.11.2). Applications take longer to load and react. I'll try turning switcheroo off again and see if it makes a difference. I have already tried renaming everything plasma in .kde but that didn't help.

My boot time has increased a few seconds -- the time from after-password to full-desktop is a bit longer. I'm not noticing any overall slowness, though.

It's a configuration option in the firmware menu. The T520 offers three choices:

* Integrated -- Intel graphics
* Discrete -- nVidia graphics
* Optimus -- switchable graphics

I selected the second one. The firmware hides the Intel graphics completely in this mode.

See that's the thing. This and Radeon Integrated + Radeon discrete are the the only hybrid graphics systems I've ever seen. I know that Intel integrated + Radeon discrete does exists and there are ways of working with it but because it's so rare I've just never learnt to do so myself.

I had the same. Slower on boot, but otherwise no difference - until readahead kick in. Now boot is exactly the same as before installing nvidia drivers.
