Steam won't start on Ubuntu 14.04.1

When I click on the icon from the Launcher, nothing happens. When I enter 'steam' in Terminal, I get this:

What to do? :( I installed Steam from the Ubuntu Software Center.

Solution 1:

This will sound crazy, but the solution is to

1. uninstall your Nvidia or AMD driver
   • I.e. sudo apt-get purge fglrx* or sudo apt-get purge nvidia-*
2. reboot
3. start Steam and let it update, while using the open drivers
4. reinstall your proprietary driver
5. and finally reboot again.

Steam has some kind of issue with the proprietary AMD/Nvidia drivers which cause the problem. For more info, have a look here: https://github.com/ValveSoftware/steam-for-linux/issues/3248

Solution 2:

I don't run steam, so cannot try this, but a suggestion from the steam community is that you need to add the libcurl module to your system.

The command suggested is

sudo apt-get install libcurl3:i386
