X crashes as well? I'm not sure if my problem is related. but Steam client segfault on startup.
Ubuntu 14.04 64bit with AMD card as well. (CEDAR 5450 - radeon driver)
current kernel is 3.13 but Steam has crashed with previous kernel too... it's not working ever since I upgraded from 13.10 to 14.04
16GB of ram, AMD x6 processor
@KopixKat, are you sure it's not this bug in glamor? If it is, then the root of the problem is #3273 / ValveSoftware/steam-runtime#13. Cleanest (but partial) workaround I've seen is to override the libgcc_s.so.1 and libstdc++.so.6 libraries from the runtime with something like...
LD_PRELOAD="/usr/lib/libstdc++.so.6 /usr/lib32/libstdc++.so.6 /usr/lib/libgcc_s.so.1 /usr/lib32/libgcc_s.so.1" ~/.local/share/Steam/ubuntu12_32/steam-runtime/run.sh steam
^ This fixed it. ^
Nothing extracted yet.
Using the FOSS Radeon driver crashes Steam and X upon starting the application.
Neither the [Stable] repositories or the [Testing] repositories can get it working.
When it does run there is an OpenGLX (Missing lib32 libraries) error right before the crash.
