机型: 台式机
Intel(R) Core(TM) i5-4690K CPU @ 3.50GHz
显卡双显卡(集成显卡与外置显卡),双显示器
00:02.0 Display controller [0380]: Intel Corporation Xeon E3-1200 v3/4th Gen Core Processor Integrated Graphics Controller [8086:0412] (rev 06)
01:00.0 VGA compatible controller [0300]: NVIDIA Corporation GK107 [GeForce GT 740] [10de:0fc8] (rev a1)
问题:开机及开机过程中,双显示都同时有显示,但是进入系统后,只有外置显卡有显示。
通过百度查询,有一种说法:使用xrandr 命令,如果只有一个connect的话,基本上就不用弄了,那属于系统级别的问题。而我的电脑,恰恰只显一个connect.(如下),故上报你们,希望能够得到你们的帮助。
