我正在尝试配置“使用 RandR 1.4 卸载图形显示”,但 xrandr 仅检测到 Intel 显卡:
$ xrandr --listproviders
Providers: number : 1
Provider 0: id: 0x45 cap: 0x2, Sink Output crtcs: 3 outputs: 3 associated providers: 0 name:modesetting
显卡(笔记本电脑 Acer Aspire V3-772G):

The NVIDIA X Server Settings tool.
This program is used to configure the NVIDIA Linux graphics driver.
For more detail, please see the nvidia-settings(1) man page.
兰德尔:
$ xrandr -v
xrandr program version 1.4.1
Server reports RandR version 1.4
PS 我不确定如何检查是否提供了适当的驱动程序接口
o A Linux kernel with CONFIG_DRM enabled and the appropriate driver
interfaces present:
o drm_gem_prime_export
o drm_gem_prime_import
o gem_prime_pin
o gem_prime_get_sg_table
o gem_prime_import_sg_table
o gem_prime_vmap
o gem_prime_vunmap

我在 Slackware 上有类似的设置:
# lspci | grep -E 'VGA|3D' 00:02.0 VGA 兼容控制器:Intel Corporation Haswell 集成图形控制器(rev 06) 01:00.0 VGA 兼容控制器:NVIDIA Corporation GK106M [GeForce GTX 765M](rev ff)}
我的 xrandr 只显示一张卡:
xrandr --listproviders 提供者: 数量: 1 提供商 0:id:0x47 上限:0xb,源输出,接收器输出,接收器卸载 crtcs:4 个输出:4 个关联的提供商:0 名称:Intel
但我的 nVidia 卡似乎仍然可以工作(我使用 bumblebee / optirun)
$ optirun glxinfo | grep“OpenGL渲染器” OpenGL 渲染器字符串:GeForce GTX 765M/PCIe/SSE2
$ optirun glxgears -info GL_RENDERER = GeForce GTX 765M/PCIe/SSE2 GL_版本 = 4.5.0 NVIDIA 352.30 GL_VENDOR = NVIDIA 公司
如果我不运行 optirun,则使用 Intel 卡:
$ glxinfo | grep“OpenGL渲染器” OpenGL 渲染器字符串:Mesa DRI Intel(R) Haswell Mobile
$ glxgears-信息 运行与垂直刷新同步。帧率应该是 与显示器的刷新率大致相同。 GL_RENDERER = Mesa DRI 英特尔(R) Haswell 移动 GL_VERSION = 3.0 梅萨 10.5.4 GL_VENDOR = 英特尔开源技术中心
