I have a Dell Inspiron 17r laptop on which I am running Ubuntu 11.10 (64-bit). The laptop has the following specifications:
Intel i7-2670QM (2.20 Ghz, 6 MB, 4 cores)
nVidia GeForce GT 525M (2 GB)
6 GB DDR3 SDRAM
It comes with hybrid graphics, according to the output from lspci:
I installed Bumblebee by following the instructions here:Code:user@user-laptop:~$ lspci | grep VGA 00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) 01:00.0 VGA compatible controller: nVidia Corporation Device 0df5 (rev ff)
Everything installed correctly, however, I am not sure whether the nVidia card was successfully disabled.
Question 1: How can I check whether Bumblebee disabled nVidia card?
Question 2: I think the Intel card is HD 3000, do I need to install any drivers for this card?
My main concern is about the overheating problems, as I have been reading a lot of threads about people having problems with Intel Sandy Bridge and overheating. Also, the fan on my laptop is constantly spinning, even though I am only browsing the Internet for instance. It is not terribly load however.
Question 3: Do I have such a processor (based on Intel Sandy Bridge technology)?
In order to monitor hardware temperature, I installed ls-sensors package. Using only Firefox with three tabs and writing this post in gEdit, I get the following readout:
Question 4: Would you agree that the temperatures are a bit high? If so, what can I do to lower them?Code:user@user-laptop:~$ sensors acpitz-virtual-0 Adapter: Virtual device temp1: +54.0°C (crit = +100.0°C) temp2: +54.0°C (crit = +100.0°C) coretemp-isa-0000 Adapter: ISA adapter Physical id 0: +51.0°C (high = +86.0°C, crit = +100.0°C) Core 0: +43.0°C (high = +86.0°C, crit = +100.0°C) Core 1: +44.0°C (high = +86.0°C, crit = +100.0°C) Core 2: +51.0°C (high = +86.0°C, crit = +100.0°C) Core 3: +50.0°C (high = +86.0°C, crit = +100.0°C)
I would highly appreciate any input on the issues above, because I am quite happy with this laptop otherwise.
Thank you in advance.
