Fixing USB Keyboard & Mouse Boot Problems in Ubuntu

Sometimes on startup, Ubuntu does not recognize my USB Keyboard & Mouse. This problem is frustrating as Windows seems to recognize them.

It took me a while to recognize the root of the problem was with the USB 3.0 ports on the Motherboard. By moving the usb connections to the USB 2.0 ports on the motherboard this problem was solved.

Problem: USB Keyboard and Mouse dont work on boot up.
Solution: Move the connectors to the devices from a standard USB 3.0 port to standard USB 2.0 port(check with your motherboard manual for specifics)

How to Restore Previous Session in Chrome

Losing your open browser tabs after a sudden system crash, unexpected reboot, or accidental window closure can completely disrupt your workflow. While Google Chrome is highly stable, structural errors can still wipe your active workspace clean.

If Chrome failed to show its automatic “Restore tabs” pop-up, don’t panic.

Here are the 4 fastest ways to restore your previous browsing session in the modern version of Google Chrome.

1. The Emergency Keyboard Shortcut (Ctrl + Shift + T)

If you accidentally closed a single window or an entire tab arrangement, you can instantly force Chrome to re-open it using a native hardware override shortcut.

  • Windows & Linux: Press Ctrl + Shift + T simultaneously.
  • Mac: Press Cmd + Shift + T simultaneously.
  • Tip: You can press this key combination repeatedly to sequentially open previously closed windows and tabs in the exact order they were terminated.

2. Using the Chrome History Menu UI

If the shortcut fails to pull up the closed window, your previous session is usually cached inside your local profile history layer.

  1. Click the three vertical dots (Menu) in the top-right corner of Chrome.
  2. Hover your cursor over History.
  3. Look for a section labeled Recently Closed.
  4. If an entire group of tabs or window was shut down together, it will display as a single item labeled “X Tabs” (e.g., 8 Tabs). Click on that specific group item to restore all pages instantly in a fresh window shell.

3. Configure Chrome to Always Restore Tabs on Startup

To prevent losing your workspace in the future, you should force the browser to cache your live environment automatically whenever it shuts down.

  1. Type chrome://settings/onStartup into your address bar and press Enter.
  2. Under the On startup configuration options, select the radio button for Continue where you left off.
  3. Close the settings tab. Chrome will now permanently remember your active tabs even after an abrupt system termination.

4. Advanced Session Recovery from Local Profile Data

If a severe crash corrupts Chrome’s memory state and wipes your history panel, you can manually extract your old tabs from the local filesystem profile data before they are overwritten by a new session.

  1. Close all active instances of Google Chrome.
  2. Navigate to your local user storage folder on your machine:
  • Windows: Press Win + R, paste %localappdata%\Google\Chrome\User Data\Default\ and hit Enter.
  • Mac: Open Finder, press Cmd + Shift + G, paste ~/Library/Application Support/Google/Chrome/Default/ and hit Enter.
  1. Locate the files named Current Session, Current Tabs, Last Session, or Last Tabs.
  2. If your current session is empty but Last Session has a substantial file size, delete the empty Current Session file, and rename Last Session exactly to Current Session. Re-open Chrome to load your recovered tabs.
Why did Chrome not ask to restore my tabs after a crash?

This typically happens if Chrome processes a background service extension as running normally during the shutdown, or if you opened a brand new blank window immediately after the crash, which overwrites the temporary crash cache storage file

Can I restore closed tabs after restarting my computer?

Yes, as long as you haven’t cleared your browser cache, you can press Ctrl + Shift + T upon launching Chrome or navigate to the History menu under ‘Recently Closed’ to retrieve the exact window layout from your previous desktop boot.
