Ubuntu在双显卡双显屏下遇到问题了,高手帮忙看看

如题,我在笔记本上安装ubuntu,由于笔记本是双显卡(Nidia+intel集成),采用网上那种prime+nvidia方法安装的显卡驱动。
现在问题出现了,安装好后切换到独立显卡nvidia后,系统出现两个桌面(1个大1个小),使用xrandr命令查看,发现有vga、LVDS两个显示屏,

--output VGA --off关闭后,显示正常了,可是怎么设置lvcd为主显示屏呢
使用xrandr --output LVDS-1-0 --primary命令无效,显示如下:
X Error of failed request: BadMatch (invalid parameter attributes)
Major opcode of failed request: 140 (RANDR)
Minor opcode of failed request: 30 (RRSetOutputPrimary)
Serial number of failed request: 38
Current serial number in output stream: 40
怎么样开机后直接显示正常啊,现在每次都要执行命令来关闭vga.
