挂起后，蒸汽客户端在启动时冻结，但在重新启动后再次工作。

Question

蒸汽工作正常，但当我应用以下步骤时，它会挂起：

1. 起动蒸汽
2. 停止蒸汽
3. 暂停我的笔记本电脑
4. (醒后)开始蒸汽

现在蒸汽客户端在启动时挂起。我只看到一个空白弹出窗口，没有任何内容。我认为这应该是登录弹出(“连接到蒸汽帐户”)。

唯一的解决办法是重新启动我的系统。如果我尝试killall steam && steam，它仍然会再次挂在同一点上。

以下是控制台输出：

我尝试了几种推荐的解决方法，例如：

• killall steam && rm ~/.steam/steam/appcache
• mv /etc/fonts/conf.d/10-scale-bitmap-fonts.conf{,.BAK}

但是，只有重新启动才能修复开始问题。

我正在使用Ubuntu14.10(64位)。(我的窗口管理器是i3。不要认为这是相关的，但我读到了关于xmonad的问题。)

Answer 1

我可以通过安装32位版本的libnss3来解决这个问题：

sudo apt-get install libnss3:i386

它解决了~/.steam/error.log中的以下错误：

[0102/162746:ERROR:nss_util.cc(1018)] Failed to load NSS libraries.

(我仍然不知道为什么在重新启动之后不会出现问题。)
