我运行了软件管理器，现在 startx 不再启动。启动笔记本电脑并登录后，屏幕停留在登录页面上（我尝试了 gdm 和 lightdm）。
切换到控制台并startx手动启动时出现以下错误：
mktemp: failed to create file via template ‘/tmp/serverauth.XXXXXXXXXX’: Permission denied
xauth: file does not exist
xauth: unable to link authority file , use -n
use: X [:<display>] [option]
-a # default pointer acceleration (factor)
-ac disable access control restrictions
-audit int set audit trail level
-auth file select authorization file

我找到了多个类似的问题并尝试了各种方法。
确保我有足够的空间磁盘：这是一个df输出，它似乎不是问题。

我的 .Xauthority 文件的权限在启动时是错误的：
root@blackbox:~# ls /home/florian/.Xauthority -al
-rw------- 1 root root 155 Mar 23 17:10 /home/florian/.Xauthority
但是如果我chown该文件并重新启动，我仍然会遇到同样的问题。
我已经卸载（使用purge）并重新安装xserver-xorg并运行，dpkg-reconfigure xserver-xorg但没有运气。
更新如果我在重试启动之前停止显示管理器，startx我会收到以下错误：
xauth: timeout in locking authority file /home/florian/.Xauthority

我发现的唯一解决方案是以 root 身份运行startx，然后它就可以工作了，但我不需要这样做！
更新 2到目前为止我发现的最佳解决方案是切换到虚拟终端，删除 .Xauthority 文件，然后运行“startx”。但我每次启动时都需要这样做。
答案1
删除 Xauthority 然后：
alt + ctrl + F1然后 ：
sudo pkill -9 Xorg然后：
startx
希望这可以帮助
答案2
尝试删除您的.Xauthority文件：
sudo rm /home/florian/.Xauthority
然后重新启动系统（使用您的普通用户帐户）
答案3
修复了这个问题：
sudo chmod 1777 /tmp /var/tmp
答案4
您收到此错误是因为您的用户没有权限访问您的 /tmp 文件夹。更改您的 /tmp 文件夹的权限，它应该可以正常工作。
chmod 755 /tmp -R
