Fedora 20 升级内核到3.18 3.19后,双显卡机器无法启动的问题

笔记本为INTEL集成显卡和NVIDIA独立显卡,Fedora 20 发布时内核为3.11,升级后为3.19,系统无法启动,同时3.11内核没有声音:

00:02.0 VGA compatible controller: Intel Corporation Sky Lake Integrated Graphics (rev 07)

01:00.0 3D controller: NVIDIA Corporation GF117M [GeForce 610M/710M/810M/820M / GT 620M/625M/630M/720M] (rev a1)


解决方法为,升级到3.19内核后,增加以下内核参数:

nouveau.modeset=0 rd.driver.blacklist=nouveau rd.driver.blacklist=drm video.allow_duplicates=1
