newbie@debian:~$lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation Core Processor Integrated Graphics Controller (rev 02)
01:00.0 VGA compatible controller: nVidia Corporation GF106 [GeForce GT 555M SDDR3] (rev a1)
看硬件有两块显卡,
newbie@debian:~$grep -B2 'Module class: X.Org Video Driver' /var/log/Xorg.0.log
[ 166.363] (II) Module intel: vendor="X.Org Foundation"
[ 166.363] compiled for 1.11.1.902, module version = 2.17.0
[ 166.363] Module class: X.Org Video Driver
--
[ 166.368] (II) Module vesa: vendor="X.Org Foundation"
[ 166.368] compiled for 1.11.0, module version = 2.3.0
[ 166.368] Module class: X.Org Video Driver
这是没有 xorg.conf 时系统就只有 interl 的 vesa 驱动, 不能发挥硬件性能.
那块 nvidia 显卡装了二进制驱动后, 启动nvidia 驱动后的日志

明明是找到了二块硬件, 但 nvidia 驱动显示 No devices detected, 怎么弄? |
