我有一个带有板载英特尔显卡和 nVidia 显卡的 Ubuntu 15.10 安装，我正尝试使用 udev/loginctl 在多座环境中进行设置。
虽然我在主英特尔服务器 (seat0) 中获得了输出，但另一个带有 nvidia 的座位 (seat-1) 拒绝启动。相关配置和日志文件已附上。
我尝试过 nouveau 和 nvidia 二进制驱动程序。Nouveau 驱动程序出现段错误，而 nvidia 驱动程序则拒绝被服务器识别。
我正在遵循这里给出的说明： https://wiki.ubuntu.com/MultiseatTeam/Instructions https://help.ubuntu.com/community/BinaryDriverHowto/Nvidia

答案1
删除 seat0 udev 规则。所有没有规则的设备都附加到 seat0。
对于 seat1 创建下一个 udev 规则：
SUBSYSTEM=="pci", DEVPATH=="/devices/pci0000:00/0000:00:05.0/0000:02:00.0", TAG+="seat", TAG+="master-of-seat", ENV{ID_AUTOSEAT}="1", ENV{ID_SEAT}="seat1"
将 /devices/pci0000... 替换为您的 nvidia 卡
重启或者触发 udev
使用
sudo loginctl attach seat1 /sys/devices/pci0000....
将显卡、键盘和鼠标安装到座位 1
在 /etc/X11/xorg.conf.d 中为 nvidia 卡创建一个文件：
/etc/X11/xorg.conf.d$ cat 20-nvidia.conf
Section "Device"
Identifier "Seat1"
Driver "nvidia"
BusID "PCI:3:0:0"
Option "ProbeAllGpus" "FALSE"
MatchSeat "seat1"
EndSection
成功，
