fedora 28 vga_switcheroo 问题和 ati radeon 问题

fedora 28 vga_switcheroo 问题和 ati radeon 问题

我使用 Fedora 28 和 Dell Inspiron 5000。它具有混合显卡。我必须在不插入电源适配器的情况下启动。登录后,我可以插入电源适配器。在关机之前我必须记住断开电源线,否则 linux 会死机。

我只用电池使用 Fedora 没有问题。但是当插入电源适配器时出现问题。例如 vlc 视频播放器冻结,或 lspci 命令失败。

我想问题出在 vga_switcheroo 支持上。

是否可以禁用 vga_switcheroo 并仅使用集成卡?

这就是vgaswitcheroo的当前状态。丢弃卡可以采用 DynOff 或 DynPwr 之间的值。

# cat /sys/kernel/debug/vgaswitcheroo/switch
0:IGD:+:Pwr:0000:00:02.0
1:DIS: :DynOff:0000:01:00.0

这是 dmesg 的摘录,显示了内核错误:
