Since I got several Intel powered PC, It’s is essential to know how graphics card works, thus I could get the fastest performance of my PC or Server.
Detect Graphics Card
Use lspci we could get the output of all PCI equipments, get the VGA related information via:
$ lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09)
To know the detailed information of this equipment:
$ lspci -v -s 00:02.0
00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) (prog-if 00 [VGA controller])
Subsystem: Hewlett-Packard Company Device 161c
Flags: bus master, fast devsel, latency 0, IRQ 57
Memory at d4000000 (64-bit, non-prefetchable) [size=4M]
Memory at c0000000 (64-bit, prefetchable) [size=256M]
I/O ports at 4000 [size=64]
Expansion ROM at <unassigned> [disabled]
Capabilities: <access denied>
Kernel driver in use: i915
Kernel modules: i915
Memory at c0000000 (64-bit, prefetchable) [size=256M]
shows the Intel Video Card with 256MB of video RAM. Or you can get the detailed via : sudo lspci -v | more
.
If you want the graphic ways, simply install following tool:
$ sudo pacman -S hardinfo
$ hardinfo
The picture shows as following:
lshw could also shows the result:
$ sudo lshw -class display

Get the config from Intel Doc
Refer to following link:
http://en.wikipedia.org/wiki/Comparison_of_Intel_graphics_processing_units, for example, My cpu is Intel(R) Core(TM) i5-2520M , then find the “Core i5-2xxxM”, it shows the graphic card is HD Graphics 3000.
Configure Intel Graphics Card
Install driver:
$ sudo pacman -S xf86-video-intel
32-bit 3D Support:
$ sudo pacman -S lib32-intel-dri
