Fedora 8 安装MyEclipse出现java: xcb_xlib.c:52: xcb_xlib_unlock: Assertion `c->xlib.lock' failed.问题的解决方案
第一种解决方法：
java: xcb_xlib.c:50: xcb_xlib_unlock: Assertion `c->xlib.lock' failed.
这是JDK导致的问题
解决办法：
还原到F7的libX11
rpm -e --nodeps libX11-1.1.3-4.fc8
rpm -e --nodeps libX11-devel-1.1.3-4.fc8
到找到下面那两个包，装上
rpm -ivh libX11-1.0.3-8.fc7.i386.rpm --该软件在
rpm -ivh libX11-devel-1.0.3-8.fc7.i386.rpm --该软件在 ... .0.3-8.fc7.i386.rpm
再加上下面两行到 /etc/yum.conf，防止更新linux的时候又恢复到新版本
# List of packages to exclude from updates or installs
exclude=libX11 libX11-devel
第二种解决方法：
首先看报错的信息：
[root@icnote eclipse]# ./MyEclipse_6_0_1GA_E3_3_1_Installer.bin

这 个问题，官方解释这是由于使用了XCB而不是LibX的缘故，关键就在于assert时，Lock问题。一种解决方案是回去使用libx，另一种则是去掉 assert时的检查。今天在linuxsir上看到有人用f9 了，突然想，是不是官方有对xlib的解决方案呢 ？所以update一下：
[root@icnote eclipse]# yum --enablerepo=development update libxcb --注意这里，这是安装libxcb-devel-1.1-1.fc9.i386.rpm软件
--其实也可以本地安装，# yum localinstall libxcb-devel-1.1-1.fc9.i386.rpm 该软件在 ... -1.1-1.fc9.i386.rpm
