Mobility Radeon HD 4650 和 Kubuntu 14.04

Mobility Radeon HD 4650 和 Kubuntu 14.04

我正在嘗試將我的 Mobility Radeon HD 4650 與 Kubuntu 14.04 一起使用。我發現專有驅動程式不適用於 Kubuntu 14.04 和新內核,我必須使用免費的 radeon 驅動程式。這是我的筆記型電腦:http://doc.ubuntu-fr.org/toshiba_satellite_p300-27z/

但我有兩個問題:

  • 安裝後(使用“nomodeset”進行安裝;沒有“nomodeset”它會凍結),我的螢幕只能在 1152x864 解析度下工作,無法選擇 1440x900,它可以與 12.04 和 fglrx 驅動程式一起正常工作。
  • 我的筆記型電腦很熱;專有驅​​動程式並非如此

我嘗試了更多方法,但沒有任何效果,所以我需要你的幫助。

謝謝

翻譯自這裡:

系統啟動後,編輯並添加到以以下內容/etc/default/grub開頭的行末尾:GRUB_CMDLINE_LINUX_DEFAULTspaceradeon.dpm=0

重要的是刪除任何nomodeset存在的GRUB_CMDLINE_LINUX_DEFAULT="quiet splash radeon.dpm=0預設值,但不要替換您可能已經存在的任何其他核心參數...

然後執行:

sudo update-grub

為了解決熱量問題,我們將卡片本身置於低功耗模式:

sudo nano /etc/init.d/ati-power-save

新增以下行:

#!/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,請替換lowdefaultautomidhigh如果需要的話。 high將提供最佳性能,但也會提供最高的 T°。)

儲存檔案並使其可執行:

sudo chmod +x /etc/init.d/ati-power-save 

現在建立允許在每次啟動時執行腳本的連結:

sudo update-rc.d ati-power-save defaults 99
