Have a look at the xorg log file. While it's tedious reading, somewhere in the file (usually several places) you will find a line that identifies your display driver/chipset. The log file is located in /var/log and is named something like xorg.log or xorg.0.log. A sample line from my log file is:
(--) PCI:*(0@0:2:0) Intel Corporation 82Q35 Express Integrated Graphics Controller rev 2, Mem @ 0xe0380000/524288, 0xd0000000
/268435456, 0xe0200000/1048576, I/O @ 0x00003430/8
Which identifies the graphics controller as one of the Intel integrated graphics chipsets. Looking a bit farther down, I find this:
(II) intel: Driver for Intel Integrated Graphics Chipsets: i810,
i810-dc100, i810e, i815, i830M, 845G, 852GM/855GM, 865G, 915G,
E7221 (i915), 915GM, 945G, 945GM, 945GME, 965G, G35, 965Q, 946GZ,
965GM, 965GME/GLE, G33, Q35, Q33,
Mobile Intel® GM45 Express Chipset,
Intel Integrated Graphics Device, G45/G43, Q45/Q43, G41
There it is: The intel GM45 Express. (The actual chipset is the 945GME, which belongs to the GM45 class.) You should see similar stuff for your graphics card.
Note that there is also an abundance of information about the monitor that X identifies at startup, what mode is selected and what modes the monitor has reported as supporting - you may need this later on.
