lightdm+i3wm无法自动登录

我按照archwiki上面配的
装了lightdm和lightdm-gtk-greeter

/etc/lightdm/lightdm.conf

[Seat: *]
session-wrapper=/etc/lightdm/Xsession
autologin-user=martinit
autologin-user-timeout=0
autologin-session=i3

$ groups
autologin wheel martinit

然后还是没用，还是要密码。。。。。。
lightdm的log如下：

Re: lightdm+i3wm无法自动登录

不明白为啥你的配置文件里面是 i3，日志里却是 i3.desktop。
按理说装了 i3-wm，应该会找到的呀。

其实也可以不用配置 autologin-session，而是根据 ~/.dmrc 机制自动登录。

哦可能是我之前写的i3.desktop 弄错了。。。。
现在我把autologin-session注释了，.dmrc中写的是Session=i3，log如下:

正常的自动登录的日志是到这里的倒数第二行就截止了，不懂为啥你这里运行的怎么就多出了这最后一行又终止了 pid=640，这也太突然了。

会不会是不是 wiki 里提到的这个原因呢？
If autologin fails with a blank screen or if the login screen immediately returns, you may need to set logind-check-graphical=true.

Re: lightdm+i3wm无法自动登录

我又看到以下错误，有没有什么关系呢

Re: lightdm+i3wm无法自动登录

这个应该没啥关系吧，登录界面的日志就是这样的。

感觉现在的问题在于，明明自动登录成功后，为啥很快的以 1 退出了，又返回到登录界面了。

可以试下重启后，以密码登录后，看下 .xsession-errors.old 里有没有异常的东西，它应该记录了自动登录过程中 xsession 留下的日志。

貌似找到问题了，这是怎么个情况呢

去看看你的 Xorg 是怎么了呗，日志文件应该是那个跟 lightdm 在一起的 x-0.log。

Re: lightdm+i3wm无法自动登录

折腾一圈儿，破案了。。。。。我装了nvidia专有驱动就好了。
我的笔记本是intel的核显+nv的独显，由于是老本子我就没打算用独显（MX130，跟核显差不多性能），就只安装了intel的显卡驱动，这时lspci里写的nv用的驱动是nouveau
但是，这是为啥呢

Re: lightdm+i3wm无法自动登录

你说这一大串backtrace不是每次开机都有的。。。

我觉得

可能系统启动太快了，LightDM 服务在图形驱动加载前就启动了。如果是这样，将下面配置加入 lightdm.conf 文件:

   [LightDM]
   logind-check-graphical=true

设置后 LightDM 会等待图形驱动加载完成后再启动 greeters/autostarting 会话。

可能还是和这个有关。

或者尝试

/etc/mkinitcpio.conf:
MODULES=(nouveau)

Re: lightdm+i3wm无法自动登录

Xorg 的 modesetting 驱动挂了。应该是它的 bug 吧。
