fvwm crashing on launch of X session
Last modified: 2007-11-30 17:11:59 EST
Description of problem:
I installed fvwm-2.5.21-4.fc6.x86_64.rpm, and when I tried to launch my session
from the login screen, I get an error that the session lasted less than 10
seconds, and it quits, returning my to my login prompt. dmesg has the following

Manual install of fvwm 2.4.20 from a tarred source works fine.
Version-Release number of selected component (if applicable):
Everytime I tried to launch X
Steps to Reproduce:
1. Install fvwm rpm from the Fedora extras repo.
2. Log in via X GUI startup
Error - session < 10 sec - quits back to login screen.
Successful launch of fvwm.
Thank you for the bug report. Without a stack trace from the crash it is
very hard to determine what caused the crash. Please see
http://fedoraproject.org/wiki/StackTraces for more information about
getting a useful stack trace.
Specifically, you'll need to install fvwm and fvwm-debuginfo. This yum command
yum --enablerepo=extras-debuginfo install fvwm-debuginfo fvwm
Once that's done, try starting X using the "failsafe session". Once the xterm
appears, try running fvwm using gdb as given here:
If it crashes again, please grab the stacktrace and append it to this bug.
This turns out to not be a "bug" with the software, but was caused by having
depreciated values in the fvwm2rc config file (that worked in 2.4.20) that
prevented the Xsession from launching. The 'MenuStyle', 'FvmwButtons', and
'wmconfig' syntax were the culprits.
