Intel-AMD混合显卡Ubuntu 23.10系统中AMD RX 6650 XT无法激活的问题求助

我组装了一台搭载Intel-AMD混合显卡的主机，系统是Ubuntu 23.10，但一直没法让我的AMD显卡“激活”——显卡上的HDMI接口完全没有输出。虽然它能被识别为PCI设备，右键菜单里的“使用独立显卡启动”选项也存在，但选了之后完全没效果。有没有大佬能给点建议或者可以尝试的方案？需要更多信息的话尽管问，谢谢！

系统信息 #

• 主板：GIGABYTE B660M DS3H AX DDR4
• GPU：Radeon RX 6650 XT (MSI)

执行lspci -k | grep -EA3 'VGA|3D|Display'的输出：

00:02.0 VGA compatible controller: Intel Corporation Alder Lake-S GT1 [UHD Graphics 730] (rev 0c)
DeviceName: Onboard - Video
Subsystem: Gigabyte Technology Co., Ltd Alder Lake-S GT1 [UHD Graphics 730]
Kernel driver in use: i915
--
03:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Navi 23 [Radeon RX 6650 XT / 6700S / 6800S] (rev c1)
Subsystem: Micro-Star International Co., Ltd. [MSI] Navi 23 [Radeon RX 6650 XT]
Kernel driver in use: amdgpu
Kernel modules: amdgpu

我已经尝试过的方法 #

DRI_PRIME #

通过“使用独立显卡启动”打开终端时，能看到DRI_PRIME=pci-0000_03_00_0。我还手动执行了export DRI_PRIME=1，但不管哪种情况，执行glxinfo | grep Device的输出都是：

Device: Mesa Intel(R) UHD Graphics 730 (ADL-S GT1) (0x4692)

而且不管有没有用独立显卡启动选项，vblank_mode=0 glxgears和glmark2的表现完全一致。

VGA Switcheroo #

我尝试启用vga_switcheroo，确认/etc/boot/config-*里有CONFIG_VGA_SWITCHEROO=y，然后在/etc/default/grub里把GRUB_CMDLINE_LINUX_DEFAULT改成了"quiet splash amdgpu.modeset=1"，重启后发现/sys/kernel/debug/里并没有vgaswitcheroo目录，应该是我的机器没有“硬件多路复用器”？这意味着什么？会是问题所在吗？
