Radeon模块启动问题
我在使用radeon模块启动时遇到问题。 出现黑屏。 如果我在blacklist.conf中添加“blacklist radeon”，我可以正常启动。 但我需要vgaswitcheroo，如果没有radeon模块则无法使用。 笔记本电脑hp pavilion dv6-3125ervideoRadeon 5650和intel ubuntu 11.04

将blacklist radeon添加到/etc/modprobe.d/blacklist.conf的末尾
在/etc/rc.local ‘ exit 0 ‘之前添加这些行
modprobe radeon echo OFF > /sys/kernel/debug/vgaswitcheroo/switch
记得制作rc.local可执行文件。
现在将重新加载radeon模块，将重新启用vgaswitcheroo并关闭ATI卡。 更冷，更安静
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 radeon）中。 这使我的系统启动稳定。
哦，可以看到，你不需要radeon卡，对吧？ 你对集成GPU感到满意吗？ 如果是这样，只需删除（使用synaptics）xorg驱动程序radeon（包名称就像xorg-driver-ati和xorg-driver-radeon或类似的东西）问题是这些驱动程序不能正常使用ubuntu的默认内核11.04
我就这么做了 英特尔卡就像以前一样工作。 vga_switcheroo到位了。 一切都很好，但你当然不能使用radeon卡。
