It is my T410’s spec.:
ThinkPad T410 (2522-B53)
i5-520M(2.4GHz), 4GB RAM, 320GB 7200rpm HD, 14.1in 1440×900 LCD, Intel 5700MHD, CDRW/DVDRW, Intel 802.11agn wireless, WWAN option, Bluetooth, Modem, 1Gb Ethernet, UltraNav, Secure Chip, 9c Li-Ion, WinXP Pro
Its Intel 5700MHD graphic card can not be recognized by Ubuntu 12.04 LTS (Precise Pangolin).
Found the solution here: “Intel HD Graphics card not recognized in System Info”
Typing it in terminal:
sudo apt-get install mesa-utils
Then I can see the driver is “Intel® Ironlake Mobile”.
