联想T60安装Ubuntu 16.04.3LTS更新重启后黑屏求助

Hey there, let's work through this black screen problem you're having on your Lenovo T60 after updating Ubuntu 16.04.3 LTS. Older machines like the T60 often run into graphics driver hiccups after system updates, so let's break down practical fixes step by step:

1. Boot into Recovery Mode First #

Since you can't get to the normal desktop, start by accessing Ubuntu's recovery menu:

• Restart your T60. As soon as the Lenovo logo pops up, hold down the Shift key to bring up the GRUB boot menu.
• Select Advanced options for Ubuntu, then pick the latest kernel version labeled (recovery mode).
• In the recovery menu, choose root to open a full-permission root shell. Enter your user password when prompted.

2. Fix Graphics Driver Conflicts #

The T60 uses an older ATI Radeon X1300/X1400 card, which often clashes with updated open-source drivers. Let's repair or switch drivers:

• First, make your filesystem writable (it's read-only in recovery mode):

  mount -o remount,rw /
  

• Refresh your package list to ensure you have the latest info:

  apt-get update
  

• Reinstall core graphics packages to fix any corrupted files:

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

• If the open-source driver still causes issues, try the legacy proprietary ATI driver (it's unsupported now but works well for older cards like yours):

  apt-get install fglrx fglrx-amdcccle
  

  After installing, initialize the driver config:

  aticonfig --initial
  

3. Force Compatibility Display Settings #

Sometimes the update switches to a resolution your T60's screen can't handle. Let's force a safe mode boot:

• From the GRUB menu, highlight the default Ubuntu entry and press e to edit boot parameters.
• Find the line starting with linux, then replace quiet splash with nomodeset.
• Press Ctrl+X or F10 to boot with this setting. Once logged in, go to System Settings > Displays and set the resolution to your T60's native option (usually 1024x768 or 1400x1050).
• To make this change permanent, edit the GRUB config:

  nano /etc/default/grub
  

  Update the line GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" to:

  GRUB_CMDLINE_LINUX_DEFAULT="nomodeset quiet splash"
  

  Save with Ctrl+O, exit with Ctrl+X, then update GRUB:

  update-grub
  

4. Roll Back Problematic Updates #

If the black screen started right after an update, a faulty kernel or package might be the culprit:

• In the root shell, list recently installed kernels:

  apt list --installed | grep -E "(linux-image|linux-headers)" | sort -V
  

• Identify the latest kernel version (the one you just updated to). Remove it with:

  apt-get purge linux-image-<version>-generic linux-headers-<version>-generic
  

  Replace <version> with the actual kernel number (e.g., 4.4.0-116-generic).
• Update GRUB to remove the old kernel entry:

  update-grub
  

• Reboot with reboot and check if the system starts normally.

Quick Tip for Long-Term Stability #

The T60 is a solid old machine, but Ubuntu's default desktop can feel heavy. If you run into more performance or display issues later, consider switching to a lighter flavor like Xubuntu or Lubuntu—they use leaner desktop environments that play nicer with older hardware.
