Chrome doesn't start (window doesn't appear) on Fedora 20 Linux

(To the moderator: please do NOT mark this as a duplicate of https://groups.google.com/a/googleproductforums.com/d/topic/chrome/tdlOv4V4jDk like you did last time.
That discussion is mainly for Windows 8 - it's really difficult for users to go through the 100+ unrelated posts there to find a solution (and there is none anyway). I'm reposting this since all my posts there didn't succeed in restoring my original post. I still don't see why all 'chrome not starting' issues related to different OSs should be muddled into one topic).

I have google chrome version 35.0.1916.153 on a Fedora 20 x86_64 machine (upgraded from Fedora 18). google-chrome no longer starts - its window doesn't appear. I upgraded to this version of Chrome from an older version to find that the problem persists.  Running google-chrome just gives

$ google-chrome
 PID namespaces supported Network namespace supportedbut failed: errno = Operation not permitted
<hang> <no window appears and this doesn't return>

The list of processes shows

$ ps -ef | grep chrome
user     26747 14220  1 20:22 pts/4    00:00:00 /opt/google/chrome/chrome

user     26753 26747  0 20:22 pts/4    00:00:00 [chrome-sandbox] <defunct>
user     26755 26641  0 20:22 pts/6    00:00:00 grep --color=auto chrome

I tried creating a new user account and running chrome - that doesn't work either. I'm able to run it as root though! - but that's obviously not what anyone wants.

Ultimately, chrome-sandbox becomes defunct. Without any error or warning message being output, I can't see why this is not a bug in chrome.

This post (https://code.google.com/p/chromium/issues/detail?id=110756) appears to be related but there's nothing there to solve this. In addition, I have another Fedora 20 system where google-chrome works with the same kernel version. So this doesn't appear to be a kernel related issue alone.

With an update to chrome version 36.0.1985.125, the error message has been improved and made more accurate, but still the same problem.

$ google-chrome
The setuid sandbox is not running as root. Common causes:
  * An unprivileged process using ptrace on it, like a debugger.
  * A parent process set prctl(PR_SET_NO_NEW_PRIVS, ...)
Failed to move to new namespace: PID namespaces supported, Network namespace supported, but failed: errno = Operation not permitted

I have kernel version 3.14.4-200.fc20.x86_64

I found the problem. The posts at


have the solution. The partition where chrome is installed shouldn't be mounted with nosuid flag. Getting rid of nosuid from the entry for /opt in /etc/fstab solves the problem.

From some of the comments there,

#10 ev...@chromium.org
We hope to eliminate our SUID-based sandboxing in the near future.
But for now, we require the SUID helper for sandboxing.

I wish the error message could be further improved by adding the following as a common cause.

* The file system on which chrome is installed is mounted with the  nosuid option
