Issue Report: Segmentation Fault on startup after Ubuntu update
I updated Ubuntu 12.04 32-bit on Sunday after installing the recommended AMD drivers, and Steam now does not start, though it worked fine before, and the console shows

line 287: 11426 Segmentation fault (core dumped) $DEBUGGER "$STEAMROOT/$PLATFORM/$STEAMEXE" "$@"

The login window does come up, and if I enter the wrong password, it does recognized that it's wrong and does not continue or crash, so verification is working.

I'm running a Phenom II X2 with an Radeon 6850.

Can you post the output of `glxinfo`, `glxgears`, and `fglrxinfo`?
KvotheTheArcane Dec 10, 2012 @ 7:58pm 
glxinfo: too long to paste, see pastebin[pastebin.com]

glxgears

27003 frames in 5.0 seconds = 5400.600 FPS
(the gears show)

fglrxinfo

display: :0 screen: 0
OpenGL vendor string: Advanced Micro Devices, Inc.
OpenGL renderer string: AMD Radeon HD 6800 Series
OpenGL version string: 4.2.11903 Compatibility Profile Context

I have fglrx-updates installed rather than fglrx. Might that matter?

Line 287 is
else
$DEBUGGER "$STEAMROOT/$PLATFORM/$STEAMEXE" "$@"
fi

which happens when $DEBUGGER is not gdb or cgdb. DEBUGGER isn't set earlier in this script (I think), but I have gdb, so perhaps if I set $DEBUGGER as an environment variable to gdb it may work?

I'll also try echoing $DEBUGGER

Okay, so debugger is actually unset, so it's running without one.
KvotheTheArcane Dec 12, 2012 @ 5:00pm 
Should I try running with GDB?
KvotheTheArcane Dec 12, 2012 @ 5:03pm 
Oh, haha, steam.sh is replaced by auto-update and loses my debugging code. Luckily it runs at least once so I can get the info

I don't remember exactly how, but I think there's a way of starting X in low graphics mode on purpose. Try googling that and logging into steam that way. Also, can you paste ALL of the output from steam at startup?
