我使用的是三星第三代英特尔 i5 笔记本电脑，配备 Radeon HD8750 和英特尔 HD4000，以及 Ubuntu 14.04
我的笔记本电脑目前只使用集成显卡。它甚至没有提到独立显卡。我认为两个显卡都打开了，这就是为什么我的笔记本电脑耗电量更多并且变得非常热。
在我之前的笔记本电脑上，我使用 bumblebee 在两个显卡之间切换。是否有任何类似的工具可用于 ATI，或者是否可以禁用其中一个卡（三星在启动菜单中没有提供此选项）。
请提出一些建议来解决这个问题。如果您需要，我可以发布任何命令的输出。

我在这里先向您的帮助表示感谢！
答案1
它可能被检测到了，看看这一点lspci -v：
超微半导体公司 [AMD/ATI] Mars [Radeon HD 8670A/8670M/8750M]
...
正在使用的内核驱动程序：radeon
您可以通过删除驱动程序来关闭它，或者按照说明radeon使用vga_switcheroo这里：
使用 vga_switcheroo
确保 vga_switcheroo 可用后，您可以使用这些选项在 GPU 之间切换。请做好锁定的准备（立即或一分钟后），此文件的存在并不意味着该机器受支持。
echo ON > /sys/kernel/debug/vgaswitcheroo/switch打开断开连接的 GPU（当前未驱动输出），但不切换输出。
echo IGD > /sys/kernel/debug/vgaswitcheroo/switch将集成显卡与输出连接起来。
echo DIS > /sys/kernel/debug/vgaswitcheroo/switch将独立显卡与输出连接起来。
echo OFF > /sys/kernel/debug/vgaswitcheroo/switch关闭当前断开的显卡。
X-Windows 会话中还有几个有用的选项：
echo DIGD > /sys/kernel/debug/vgaswitcheroo/switch当 X 服务器下次重新启动时，排队切换到集成显卡。
echo DDIS > /sys/kernel/debug/vgaswitcheroo/switch当 X 服务器下次重新启动时，排队切换到独立显卡。
cat /sys/kernel/debug/vgaswitcheroo/switch允许您验证混合显卡的当前状态。通常，会有两行输出 - 一行应指示“Pwr”，另一行应指示“Off”。
请注意，您必须以 root 身份运行这些命令sudo。您还可以使用上述命令检查当前设置的操作cat- 示例输出（请注意，您可以通过将最后一组数字与lspci卡片旁边的数字进行比较来判断哪张卡片是哪张）：
0:IGD:+:Pwr:0000:00:02.0
1:DIS: :DynOff:0000:01:00.0
我认为如果只设置使用集成卡，则可以关闭独立卡。
注意：我尝试让 AMD 卡在第二代 Intel i5 笔记本电脑上运行 - 但由于没有连接到任何视频输出，所以没有成功...我不得不通过 SSH 来修复这个问题。因此，在机器上运行 SSH 服务器以便您可以远程访问它可能是一个好主意。
