Finding the right name for your Intel graphics chipset

The output of lspci does not always provide enough information about graphics card and integrated graphics chipsets :

fool@localhost:~$ lspci -nn |egrep “VGA|Display”
00:02.0 VGA compatible controller [0300]: Intel Corporation 4 Series Chipset Integrated Graphics Controller [8086:2e32] (rev 03)
00:02.1 Display controller [0380]: Intel Corporation 4 Series Chipset Integrated Graphics Controller [8086:2e33] (rev 03)

In this case, this information “Intel Corporation 4 Series Chipset Integrated Graphics Controller”  is not sufficient to find the right name of this Intel graphics chipset.  There are two solutions to solve it :

fool@localhost:~$grep -i chipset /var/log/Xorg.0.log

[    17.764] (II) intel: Driver for Intel Integrated Graphics Chipsets: i810,
[    17.770] (II) intel(0): Integrated Graphics Chipset: Intel(R) G41
[    17.770] (–) intel(0): Chipset: “G41”

fool@localhost:~$dmesg |grep -i agp

[    1.008912] Linux agpgart interface v0.103
[    1.009057] agpgart-intel 0000:00:00.0: Intel G41 Chipset
[    1.009142] agpgart-intel 0000:00:00.0: detected gtt size: 2097152K total, 262144K mappable
[    1.010058] agpgart-intel 0000:00:00.0: detected 32768K stolen memory
[    1.010181] agpgart-intel 0000:00:00.0: AGP aperture is 256M @ 0xe0000000

With this information, it will be much more easier to use the right driver and tune the Xorg configuration file. (if necessary)

Hope this helps !
