I use debian amd64 with Nvidia graphics hardware[GeForce GT 755M],so I followed wiki that debian gives: https://wiki.debian.org/Steam

but every time I run steam it gives this:
$ steam
Running Steam on debian 8 64-bit
STEAM_RUNTIME is enabled automatically
[2017-03-03 20:55:50] Startup - updater built Jan 19 2017 01:22:13
Looks like steam didn't shutdown cleanly, scheduling immediate update check

Hello @ccxxccxxy, this usually is an indication that your 32 bit opengl driver is not setup properly. Are you able to use a 32 bit opengl application outside of steam?

If you are using an optimus laptop, I may be less hassle to get the integrated graphics working with 32 bit opengl before trying to use nvidia.
