Introduction

This page contains links to the best fixes for the most common Ubuntu problems.

If you think problem's link could be improved or could have a better link, please propose the change in this Ubuntu Forums thread for further discussion.

Warning! Please note down any errors and warnings you encounter as many issues are actually similar but not identical. Thus, a solution applied might not have any effect or might even worsen the problem.

Useful tools for recording errors and warning messages include a text editor, the Print Screen command, etc.

Log Files

Below are a few locations where you can find logs which might aid you in reproducing or pinpointing the errors:

/var/log

Some of these logs in /var/log can be accessed via System ======>Administration ====> System logs

/home/user/.xsession-errors

Any file with a "." in front of it is a hidden file. To view all hidden files, press Ctrl + H. If you wish to view all hidden files permanently and are using Nautilus, go to Edit =====> Preferences ====> View. Under "Default View", check the box "Show hidden and backup files".

You can use Text Editor to view the .xsession-errors.

/home/user/.bash_history

This is a hidden file and again, you can use Text Editor view .bash_history. .bash_history can be very useful for pinpointing commands responsible for certain error messages.

If you do not want to open .bash_history, you can launch the terminal and then in the terminal, press Ctrl+R. Then, use your arrow keys to cycle through the commands.
