登录循环 - “BadValue（整数参数超出操作范围）” - 16.04

Question

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 后，我现在通过登录循环被 Unity 锁定，在.xsession-errors 中出现以下错误：

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

我还在Xorg日志中发现了这一点：

对此错误消息的网络搜索不会产生很多相关结果。

我试过降级到 v364，然后再回到 v361 无济于事 我试过清除 xserver-xorg、xserver-xorg-core、nvidia*、lightdm 无济于事

完全重新格式化和重新安装会产生巨大的破坏性，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。如何在不完全重新格式化和重新安装的情况下清除/恢复/重置我的设置和/或包和/或库到正常状态？

Answer 1

添加+iglx到/usr/share/lightdm/lightdm.conf.d/50-xserver-command.conf.

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

之后，您可以重新启动或 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，但它未能清除所有共享对象，因此我遇到的本质上是一个库问题。

使用清除所有 NVIDIA 软件包后apt，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（有些包含单词，nvidia而有些只包含nv）。

3. 运行ldconfig。

4. 运行ldd $( which glxinfo )。

5. 检查输出ldd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 安装 NVIDIA 364 驱动程序apt。

8. 重启。
