Login Loop - “BadValue (integer parameter out of range for operation)” - 16.04
问题描述
Ubuntu16.04安装nvidia显卡驱动后卡在登陆界面循环登陆，查看~/.xession-errors文件，显示：
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
问题估计
OpenGL出现问题
解决方案
在 /usr/share/lightdm/lightdm.conf.d/50-xserver-command.conf 路径下加上 +iglx 效果如下：
[SeatDefaults]
# Dump core
xserver-command=X -core +iglx
重启图形界面
sudo service lightdm restart
是否解决
解决，再次启动图形界面依然循环登陆，但是xession-errors不报错，显示
openConnection: connect: No such file or directory
cannot connect to brltty at :0
