似乎关闭显示器会禁用水槽?并且在再次打开电视时不会重新启用。hdmi-output-0:HDMI / DisplayPort(优先级:5900,不可用)
“ 不可用 ”应为“ 可用 ”
我假设您正在使用带有fglrx的ATI卡。尝试
aticonfig --acpi-services=off
不确定此设置是否持久。如果是这样,则再次打开该命令。
aticonfig --acpi-services=on
我怀疑这会奏效。编辑>(没有)
如user53740所发布。注销/恢复音频。打开或关闭显示器会禁用HDMI音频。如果您真的不想注销,可以再次删除hdmi插件,然后将恢复hdmi音频。不要经常这样做。只有在你绝望的时候。
