嘗鮮試用FreeBSD10.0 Release，發現安裝Intel集成顯卡時候跟FreeBSD9.0不同http://www.linuxidc.com/Linux/2014-02/96132.htm ，主要就是彈出錯誤：unknown type name GLDEBUGPROCARB。
過程如下：
1、通過portsnap升級ports trees，首次使用通過命令：portsnap fetch extract，否則可以使用命令portsnap update
2、依照http://blog.csdn.net/cheviko/article/details/18909803 rebulid 各個pkg，
a) 升級libdrm：portmaster libdrm
b) 升級libGL：portmaster libGL #通過安裝完成的提示可以看出已經同事安裝了libGLU
c) 升級libGLU：如果在上一步同時完成則不用操作，否則:portmaster libGLU
d) 升級dri：portmaster dri
e) 升級xf86-video-intel：portmaster xf86-video-intel #安裝提示現實已升級了xorg-server
f) 升級xorg-server:如果上一步沒有提示已升級則: portmaster xorg-server
但是升級libGL時發現跳出錯誤：unknown type name GLDEBUGPROCARB
解決方案：刪除the packages graphics/dri and graphics/libGL
命令：
pkg delete -f dri
pkg delete -f libGL
3、Xorg -configure 生成xorg.conf.new文件，此時可能出現黑屏，不用擔心用 ctrl+alt+del重啟
4、配置文件[FILE]/etc/X11/xorg.conf[/FILE]，我的筆記本是1366*768的寬屏設置，從/var/log/Xorg.0.log 中讀取以下信息：
(II) MGA(0): Supported additional Video Mode:
(II) MGA(0): clock: 69.3 MHz Image Size: 310 x 174 mm
(II) MGA(0): h_active: 1366 h_sync: 1398 h_sync_end 1430 h_blank_end 1470 h_border: 0
(II) MGA(0): v_active: 768 v_sync: 771 v_sync_end 776 v_blanking: 786 v_border: 0
將按照ModeLine的格式配置：
ModeLine <name> <clock> <4 horiz. timings> <4 vert. timings>
配置結果：
Section "Monitor"
Identifier "Monitor0"
VendorName "Monitor Vendor"
ModelName "Monitor Model"
ModeLine "1366x768" 69.3 1366 1398 1430 1470 768 771 776 786
Option "DPMS"
EndSection
5、正常情況下您的鍵盤鼠標都無法使用，需要更新鍵盤鼠標驅動：
portmaster xf86-input-mouse
portmaster xf86-input-keyboard
6、正常情況下，現在您可以正常使用喽。
