我在使用 radeon 模块启动时遇到问题。出现黑屏。如果我将“blacklist radeon”添加到 blacklist.conf，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 dv6-3125er 视频 Radeon 5650 和英特尔 ubuntu 11.04

答案1
我也遇到了同样的问题。系统无法在加载 Radeon 的情况下启动。我这样做了：
添加blacklist radeon到末尾/etc/modprobe.d/blacklist.conf
在 ' 之前添加这些行出口 0' 在/etc/rc.local
modprobe radeon
echo OFF > /sys/kernel/debug/vgaswitcheroo/switch
记得让 rc.local 可执行。
现在将重新加载 radeon 模块，重新启用 vgaswitcheroo 并关闭 ATI 卡。更凉爽，更安静
答案2
您可以在将 radeon 模块列入黑名单的情况下启动，然后在 rc.local (modprobe radeon) 中加载它。这使我的系统启动稳定。
答案3
哦，正如你所见，你不需要 radeon 卡，对吧？你对集成 GPU 很满意？如果是这样，只需删除（使用 synaptics）radeon 的 xorg 驱动程序（软件包名称类似于 xorg-driver-ati 和 xorg-driver-radeon 或类似名称）即可。问题是这些驱动程序无法与 ubuntu 11.04 的默认内核正常工作
我刚刚这样做了。英特尔卡的工作方式与以前一样。vga_switcheroo 已到位。一切都很好，但是当然你不能使用 radeon 卡。
