Yesterday, I wanted to open Steam, but it didn't open. After some digging, I discovered the error:

ILocalize::AddFile() failed to load file "public/steambootstrapper_english.txt". [2018-03-28 08:21:21] Startup - updater built Nov 23 2016 01:05:42 SteamUpdateUI: An X Error occurred X Error of failed request: BadValue (integer parameter out of range for operation)

After reinstall steam (both from the Ubuntu repos and from steampowered.com) I saw several people suggesting things with runtime (but I couldn't find the Steam Runtime in my reinstall), and deleting libstdc++.so.6. This all didn't work for me.

Strange thing is, I reckon it stopped working when I installed the nvidia-390 driver, but I can't install the driver that worked for me because apt always install nvidia-390. My third screen, connected to my Intel HD Graphics, also stopped working with this driver. So, how do I get Steam working?

Hardware: CPU: Intel Core i5 6400 GPU: NVIDIA GeForce GTX 1060 Software: Ubuntu 17.10 with KDE & SDDM installed (though it's not Kubuntu)


When your nvidia drivers are properly installed you can confirm this by issuing from a terminal


which should give you output similar to

whereas when nvidia drivers are in an inconsistent state you will see this


Failed to initialize NVML: Driver/library version mismatch

which is probably the case here ... I suggest you reinstall the drivers

  • Whoops. Forgot to mention I switched to Solus. Even though that's the case, I highly doubt it was anything else than the drivers. I'll mark this anwser as the solution, even though I had difficulties reinstalling the driver. – TooMuchRAM Aug 3 '18 at 20:02
