登录循环 – “BadValue（整数参数超出操作范围）” – 16.04

我使用手动安装的NVIDIA 361驱动程序运行Ubuntu 16.04 LTS。 将驱动程序升级到v367之后，我现在被锁定在Unity之外，并且登录循环中出现以下错误 ： .xsession-errors ：

X Error of failed request: BadValue (integer parameter out of range for operation) Major opcode of failed request: 154 (GLX) Minor opcode of failed request: 3 (X_GLXCreateContext) Value in failed request: 0x0 Serial number of failed request: 32 Current serial number in output stream: 33 openConnection: connect: No such file or directory cannot connect to brltty at :0 

我也在Xorg日志中发现了这个：

然后这进一步下降：

对此错误消息的Web搜索不会产生许多相关结果。

我已经尝试降级到v364然后回到v361无济于事我试过清除xserver-xorg，xserver-xorg-core，nvidia *，lightdm无济于事我试过重新安装ubuntu-desktop无济于事

完整的重新格式化和重新安装将极具破坏性，我想不惜一切代价避免这种情况。

.xsession-errors中的错误消息始终保持不变。 如何在不重新格式化和重新安装的情况下，将我的设置和/或包和/或库清除/恢复/重置为理智状态？

Answer 1

在/usr/share/lightdm/lightdm.conf.d/50-xserver-command.conf +iglx添加到xserver-command。

 [SeatDefaults] # Dump core xserver-command=X -core +iglx 

之后你要么重新启动，要么重新启动Ctrl-Alt-F1，登录和sudo service lightdm restart 。

奇迹般有效

Answer 2

我解决了这个问题。 虽然我尝试手动卸载手动安装的361驱动程序，但它无法清理所有共享对象，因此我遇到的本质上是库问题。

在使用apt 清除所有NVIDIA软件包之后 ，我解决了以下问题：

1. 通过运行以下命令找到所有361驱动程序共享对象文件，不包括任何垃圾文件夹，主文件夹和Steam游戏文件夹：

    locate so.361.45 | egrep -vi "trash|steam|^/home" 

2. 删除可疑的共享对象文件（一些包含单词nvidia而其他文件只包含nv ）。

3. 运行ldconfig 。

4. 运行ldd $( which glxinfo ) 。

5. 检查ldd的输出并确保没有任何条目指向任何陈旧的NVIDIA 361.45共享对象。

6. 重启。

7. 通过apt安装NVIDIA 364驱动程序。

8. 重启。
