I am using NIS + autofs + NFS4 for home directories Abstract from my F13_install "log" If SElinux is enabled then it is necessary to use SELinux Management to set Boolean ssh allow host key authentication if direct ssh from another machine is required. Also setsebool -P use_nfs_home_dirs I have tried adding a new local user on a client machine and the problem is not there Not a definitive test as the new user will have different defaults. I have tried adding a new user to the server (Centos5.5) and logged into the client - "justtheflight" crashes. This suggests that it is the NFS mount that is causing the problem I have no idea why this should be! The new users should have "default" settings for the options below I have not tested all these yet The sandbox does crash but the nosandbox does NOT - see below > > Some hints regarding browser config: > - take a look at your config and change to default options for the time being > Tools button > Options > Under the Hood: > Content settings: > JavaScript <--- allow all sites, no exceptions > Plug-ins <--- allow all sites, no exceptions > try all ON and all OFF > Use DNS prefetching ... <--- test with ON and OFF > Enable phishing and malware ... <--- test with ON and OFF > Change proxy settings: > Direct internet connection <--- yes, if you can > Translate ... <--- turn it OFF > - extensions > Tools button - Tools - Extensions > If you have any, try to disable them all,later one by one, then restart > the browser and see what happens. > > Debugging: > http://code.google.com/p/chromium/wiki/LinuxDebugging > >From a terminal (gnome terminal, xterm, etc): > $ CHROME_IPC_LOGGING=1 google-chrome --log-level=0 --enable-logging=stderr >& > .chrom.log http://www.justtheflight.co.uk/ > This will generate a log file .chrom.log in your home dir.
