我正在尝试将我的 Mobility Radeon HD 4650 与 Kubuntu 14.04 一起使用。我发现专有驱动程序无法与 Kubuntu 14.04 和新内核配合使用,因此我必须使用免费的 Radeon 驱动程序。这是我的笔记本电脑:http://doc.ubuntu-fr.org/toshiba_satellite_p300-27z/
但我有两个问题:
- 安装后(使用“nomodeset”使安装工作正常;没有“nomodeset”它会冻结),我的屏幕只能在 1152x864 分辨率下工作,无法选择 1440x900,而 12.04 和 fglrx 驱动程序可以正常工作。
- 我的笔记本电脑很热;使用专有驱动程序则不会这样
我尝试了更多方法,但没有任何效果,所以我需要你的帮助。
谢谢

译自这里:
系统启动后,编辑并添加以下内容/etc/default/grub
至行尾:GRUB_CMDLINE_LINUX_DEFAULT
spaceradeon.dpm=0
重要的是删除任何nomodeset
存在的GRUB_CMDLINE_LINUX_DEFAULT="quiet splash radeon.dpm=0
默认设置,但不要替换您可能已经拥有的任何其他内核参数......
然后执行:
sudo update-grub
为了解决发热问题,我们将卡本身置于低功耗模式:
sudo nano /etc/init.d/ati-power-save
添加以下行:
#!/bin/sh
# ATI power save
echo profile > /sys/class/drm/card0/device/power_method
echo low > /sys/class/drm/card0/device/power_profile
(如果您想要更好的性能,请根据需要替换为、或low
。default
将auto
提供最佳 性能,同时也提供最高的 T°。)mid
high
high
保存文件并使其可执行:
sudo chmod +x /etc/init.d/ati-power-save
现在创建允许在每次启动时执行脚本的链接:
sudo update-rc.d ati-power-save defaults 99
