Android Studio无法在OpenSUSE上启动（打开的文件太多）

Question

我已经有一段时间没有在StackOverflow上发布文章了，所以请原谅我将其放在错误的位置，但这是问题所在：

我最近为相对较新安装的OpenSUSE系统下载了Android Studio，已经安装了openjdk-devel，并且每当我尝试启动studio.sh时，都会显示启动屏幕，并在整个加载过程中出现70％的错误，然后向控制台发送垃圾邮件有：

我有点机智。 我尝试链接到openjdk和Oracle的最新JDK版本。 我试过玩最大打开文件数（在/etc/environment/limits.conf中设置），但是尽管错误表明打开文件过多，但似乎没有任何作用。 我曾尝试升级到openjdk1.8，降级到1.7，多次重新安装所有内容，但我似乎无法启动它。

这是合法错误还是严重的用户错误？ 关于我可以寻找解决方案的任何想法？

编辑：/etc/environment/limits.conf

 # /etc/security/limits.conf # #Each line describes a limit for a user in the form: # #<domain> <type> <item> <value> # #Where: #<domain> can be: # - a user name # - a group name, with @group syntax # - the wildcard *, for default entry # - the wildcard %, can be also used with %group syntax, # for maxlogin limit # #<type> can have the two values: # - "soft" for enforcing the soft limits # - "hard" for enforcing hard limits # #<item> can be one of the following: # - core - limits the core file size (KB) # - data - max data size (KB) # - fsize - maximum filesize (KB) # - memlock - max locked-in-memory address space (KB) # - nofile - max number of open files # - rss - max resident set size (KB) # - stack - max stack size (KB) # - cpu - max CPU time (MIN) # - nproc - max number of processes # - as - address space limit (KB) # - maxlogins - max number of logins for this user # - maxsyslogins - max number of logins on the system # - priority - the priority to run user process with # - locks - max number of file locks the user can hold # - sigpending - max number of pending signals # - msgqueue - max memory used by POSIX message queues (bytes) # - nice - max nice priority allowed to raise to values: [-20, 19] # - rtprio - max realtime priority # #<domain> <type> <item> <value> # #* soft core 0 #* hard rss 10000 #@student hard nproc 20 #@faculty soft nproc 20 #@faculty hard nproc 50 #ftp hard nproc 0 #@student - maxlogins 4 * hard nofile 65535 * soft nofile 65535 root soft nofile 65535 root hard nofile 65535 # End of file

这是shell的一些神秘输出：

$ whoami
corey
$ ulimit -Hn
256
$ ulimit -Sn
256
$ su 
$ whoami
root
$ ulimit -Hn
65535
$ ulimit -Sn
65535
$ su corey
$ whoami
corey
$ ulimit -Hn
65535
$ ulimit -Sn
65535
$ exit
$ exit // getting back to login shell
$ whoami
corey
$ ulimit -Hn
256
$ ulimit -Sn
256

因此，看起来好像在打开新的外壳程序时正确更改了限制（对于上面的嵌套su而言，即使不先切换到root），但在启动计算机或打开新的外壳程序时也不会更改。 我确认通过运行su USERNAME ./studio.sh终于可以启动该程序了，因此至少可以解决该问题。 有什么线索可说，shell实例是怎么回事？

Answer 1

至于现在，这是怎么回事：

$ whoami        //session 1 (256)
corey
$ ulimit -Hn
256
$ ulimit -Sn
256
$ su            //session 2 (65k)
$ whoami
root
$ ulimit -Hn
65535
$ ulimit -Sn
65535
$ su corey      //session 3 (65k)
$ whoami
corey
$ ulimit -Hn
65535
$ ulimit -Sn
65535
$ exit      //session 2(65k)
$ exit     // getting back to login shell: session 1 (256)
$ whoami
corey
$ ulimit -Hn
256
$ ulimit -Sn
256

su命令使更改登录会话的所有者（即最初通过登录系统创建该会话的用户）成为可能， 而所有者不必先注销该会话。 因此，当您注销两次（从root和corey会话）时，您将返回到原来的限制似乎起作用的初始会话。 我不知道这怎么会是，如果你重新启动系统正常，所以我建议你重新登录下（意味着明确注销和登录） corey ，我敢打赌，从新值limits.conf应最后申请。
