Radeon模块引导问题

Question

我在启动radeon模块时遇到了问题。出现黑色屏幕。如果我添加“黑名单radeon”到blacklist.conf，我可以正常启动。但是我需要没有radeon模块的vgaswitcheroo。笔记本电脑hp展馆dv6-3125 hp视频Radeon 5650和英特尔ubuntu 11.04

Answer 1

我也有同样的问题。系统不会在radeon加载后启动。我做了这个：

将blacklist radeon添加到/etc/modprobe.d/blacklist.conf末尾

在/etc/rc.local中的“退出0”之前添加这些行

modprobe radeon
echo OFF > /sys/kernel/debug/vgaswitcheroo/switch

记住要使rc.local可执行。

现在radeon模块将被重新加载，vgaswitcheroo将被重新启用，ATI卡将被关闭。更凉爽、更安静

Answer 2

您可以使用列入黑名单的radeon模块启动，然后将其加载到rc.local (modprobe )中。这使我的系统启动稳定。

Answer 3

哦，正如所见，你不需要radeon卡，对吧？你对集成GPU满意吗？如果是这样的话，只需删除(使用synaptics) radeon的xorg驱动程序(包名类似xorg- drivers和xorg- drivers之类的东西)，问题是这些驱动程序在ubuntu11.04的默认内核中无法正常工作。

我就是这么做的。英特尔卡和以前一样工作。vga_switcheroo就位了。一切都很好，但你当然不能用radeon卡。
