停止 fglrx 在引導時載入/解除安裝 fglrx 模組而不解除安裝它

  • November 19, 2014

我在筆記型電腦上安裝了 Fedora 19，它具有 Intel 集成顯卡和獨立 AMD 顯卡。我一直在使用該radeon驅動程序，它適用於大多數東西——儘管我最近嘗試了該fglrx驅動程序，發現它速度更快，並且具有更好的電源管理，儘管一些基於 OpenGL 的程序無法正常執行。

那麼如何fglrx在啟動時禁用驅動程序載入，使其回退到radeon驅動程序上？

我已經嘗試通過編輯/etc/modprobe.d/blacklist-fglrx.conf文件來做到這一點

# Advanced Micro Devices, Inc.
# radeon conflicts with AMD Linux Graphics Driver
blacklist radeon

通過註釋該blacklist radeon行，並添加 `blacklist fglrx_pci

  • 項目清單

`在它下面。這只是導致 GUI 登錄螢幕無法載入，所以我不得不切換到 TTY 並編輯回原來的樣子。

lspci -k``fglrx已安裝（與未安裝的唯一區別Subsystem: Lenovo Radeon HD 6370M/7370M未顯示，並radeon用作 AMD 驅動程序* - 當剛剛列入黑名單時，我認為唯一的更改radeon是使用）：

這是安裝程序製作的 RPM （安裝程序提供直接安裝或為 openSUSE 或 RedHat 建構包，我使用最新的 RedHat 64a 選項），這是從中提取的 RPM 安裝/解除安裝腳本。

我知道modprobe在系統啟動時嘗試使用刪除模組 - 這不起作用，導致modprobe: FATAL: Module fglrx is in use.

將驅動程序列入黑名單*（並刪除/etc/X11/xorg.conf- 安裝後需要創建一個fglrx（看起來像這樣），而 Fedora無論如何都不需要一個）*的工作原理是使用 radeon 驅動程序 - 這裡的問題是，很多應用程序都沒有不行，Gnome Shell 和 GDM 顯示： 哦，沒有什麼問題 GDM 和 GNOME 錯誤螢幕

但是，解除安裝驅動程序並重新啟動始終有效。

例如，將此黑名單應用於/etc/modprobe.d/blacklist-fglrx.conf：

# Advanced Micro Devices, Inc.
# radeon conflicts with AMD Linux Graphics Driver
#blacklist radeon
blacklist fglrx
blacklist amd_iommu_v2
blacklist fglrx_pci

並刪除xorg.conf導致上述 GDM 錯誤。然後我可以（並且已經）切換到 TTY，並用於systemctl從 GDM 切換到 LightDM 並登錄到 Xfce（這似乎工作正常）。諸如此類的應用程序cairo-dock因分段錯誤而失敗。glxinfo給出：

name of display: :0.0
X Error of failed request:  BadRequest (invalid request code or no such operation)
 Major opcode of failed request:  153 (GLX)
 Minor opcode of failed request:  19 (X_GLXQueryServerString)
 Serial number of failed request:  12
 Current serial number in output stream:  12

systemctl將此顯示為 GDM 的狀態（在我切換到 LightDM + Xfce 之前），即使它崩潰了：

gdm.service - GNOME Display Manager

這裡還有來自/var/log/gdm/:0.log, /var/log/Xorg.0.log&的日誌/var/log/Xorg.0.log.old- 我檢查了每個日誌的時間戳，我認為 GDM 和舊的 Xorg 日誌是正確的日誌 - 後面的 Xorg 日誌是來自目前 Xfce 會話的日誌，也應該是相關的。

我認為問題是在某個地方仍然有一些配置告訴它使用 fglrx 驅動程序，或者有一個更新檔版本的 libGL（或類似的東西）安裝了 fglrx 需要 fglrx（在這種情況下這可能是無法解決的…… ….）。

我最終只寫了一個腳本，可以用來安裝和解除安裝驅動程序，以及設置xorg.conf我的系統需要它：

#!/bin/bash
if [[ ! $(whoami) = "root" ]]; then
   echo -e "\033[1;31mPlease run this as root\033[0m"
   exit 1
fi

if [ "$1" = "enable" ]; then
   echo -e "\033[22;34mInstalling fglrx... ('/usr/share/fglrx64_p_i_c.x86_64')\033[1m\033[0m"
   sleep 3
   sudo rpm -ivh /usr/share/fglrx-amd-RPM/fglrx64_p_i_c-14.301.1001-1.x86_64.rpm
   if [ -f "/etc/X11/xorg.conf" ]; then
       echo "Backing up 'etc/X11/xorg.conf'"
       mv "/etc/X11/xorg.conf" "/etc/X11/xorg.conf.bak.$(date)"
   fi
   echo "Preparing /etc/X11/xorg.conf"
   echo -e 'Section "ServerLayout"\n   Identifier     "aticonfig Layout"\n Screen      0  "aticonfig-Screen[0]-0" 0 0\nEndSection\n\nSection "Module"\nEndSection\n\nSection "Monitor"\n   Identifier   "aticonfig-Monitor[0]-0"\n Option      "VendorName" "ATI Proprietary Driver"\n Option      "ModelName" "Generic Autodetecting Monitor"\n   Option      "DPMS" "true"\nEndSection\n\nSection "Device"\n Identifier  "aticonfig-Device[0]-0"\n   Driver      "fglrx"\n   BusID       "PCI:1:0:0"\nEndSection\n\nSection "Screen"\n   Identifier "aticonfig-Screen[0]-0"\n    Device     "aticonfig-Device[0]-0"\n    Monitor    "aticonfig-Monitor[0]-0"\n   DefaultDepth     24\n   SubSection "Display"\n      Viewport   0 0\n        Depth     24\n  EndSubSection\nEndSection\n' > "/etc/X11/xorg.conf"

elif [ "$1" = "disable" ]; then
   echo "\033[22;34mUninstalling fglrx... ('fglrx64_p_i_c.x86_64')\033[1m\033[0m"
   sleep 3
   sudo rpm -ev fglrx64_p_i_c.x86_64
else
   lsmod | grep fglrx
   echo -e "\033[22;34mThe options for the script are 'enable' 'disable'\033[1m\033[0m"

fi
exit

我也許可以嘗試拆開rpm 腳本，看看它在安裝/解除安裝期間做了什麼，但我認為上述解決方案更簡單。

使用modprobe命令。假設驅動程序稱為 radeon 和 fglrx，您可以：

modprobe -r radeon 
modprobe -r fglrx

為了檢查這些是否真的是正確的模組，請執行lsmod

假設這些程序可以滿足您的需要，您可以編輯您的模組
