Ubuntu 16.04下卸载amdgpu-pro并切换至开源Radeon驱动求助

Hi there, let's get you sorted out switching back to the open-source radeon driver—your Radeon HD7770 (Verde) is fully supported by this driver, so that's the right call for your use case. Here's a step-by-step guide tailored to your setup:

Step 1: Fully Uninstall amdgpu-pro 17.50 #

First, we need to wipe the closed-source driver completely to avoid conflicts:

• Run the official uninstall script (this is the cleanest method if it's available):

  sudo amdgpu-pro-uninstall
  

• If the script throws an error (sometimes happens with older versions), use dpkg to manually remove all related packages:

  sudo dpkg -l | grep amdgpu-pro | awk '{print $2}' | sudo xargs dpkg -P
  

• Clean up leftover configuration files and unused dependencies:

  sudo apt-get purge amdgpu-pro*
  sudo apt-get autoremove --purge
  sudo apt-get clean
  

Step 2: Enable the Open-Source Radeon Driver #

Ubuntu 16.04 includes the radeon driver by default, but amdgpu-pro might have blacklisted it. Let's fix that:

• Check for any blacklist files created by amdgpu-pro in /etc/modprobe.d/:

  sudo nano /etc/modprobe.d/amdgpu-pro.conf
  

  If you see a line like blacklist radeon, comment it out by adding a # at the start. If the file only exists to block radeon, you can safely delete it entirely.
• Update the initramfs to ensure the system loads the radeon driver on boot:

  sudo update-initramfs -u
  

Step 3: Verify the Switch #

Reboot your system, then confirm everything worked:

• Check which kernel driver is in use for your GPU:

  lspci -k | grep -EA3 'VGA|3D|Display'
  

  You should see Kernel driver in use: radeon in the output—this means the switch was successful.
• For an extra check, verify the OpenGL renderer:

  glxinfo | grep "OpenGL renderer"
  

  It should show a line referencing your Radeon HD7770 and the radeon driver.

Troubleshooting Tips #

• If you run into display issues (like wrong resolution or Cinnamon not loading properly), reinstall the Xorg radeon packages:

  sudo apt-get install --reinstall xserver-xorg-video-radeon xserver-xorg-core
  

• After switching, test Factorio again—many users report better stability with the open-source radeon driver on older AMD cards like yours, which should resolve that memory leak issue you saw with 17.50.
