lately,I meet a question about xdm and gdm

I use openrc init , DISPLAYMANAGER="gdm" in /etc/conf.d/xdm

rc-update add xdm default

Code:

$:~ /etc/init.d/xdm status
xdm crashed

Code:

dc@K650C ~ $ /etc/init.d/xdm status
 * status: crashed
dc@K650C ~ $ sudo /etc/init.d/xdm stop
Password:
 * Stopping gdm ...
 * start-stop-daemon: fopen `/run/gdm/gdm.pid': No such file or directory [ ok ]
dc@K650C ~ $ /etc/init.d/xdm status
 * status: stoped


last week it was supposed like this,which is normal
Code:

dc@K650C ~ $ /etc/init.d/xdm status
 * status: started
dc@K650C ~ $ sudo /etc/init.d/xdm stop
Password:
 * Stopping gdm ...                                [ OK ]
dc@K650C ~ $ /etc/init.d/xdm status
 * status: stoped


now gdm can launch normally, all are fine ,with xdm status crashed
and with xdm crashed , I can't do /etc/init.d/xdm start/stop/restart ,that is the only difference . I can't stop or restart the gdm via xdm

Code:

dc@K650C ~ $ sudo /etc/init.d/xdm stop
Password:
 * Stopping gdm ...
 * start-stop-daemon: fopen `/run/gdm/gdm.pid': No such file or directory [ ok ]
dc@K650C ~ $ /etc/init.d/xdm status
 * status: stopped


the xdm stoped , but the gnome-session is launched , and all as normal .
xdm is not able to control gdm at all after it launchs gdm the first time .

whatever stop/restart xdm , nothing happened to gdm session.

please help me to make xdm stop/restart correct able to control gdm or the DISPLAYER ,thank you.

now the system is all right

and I can't stop gdm once xdm launchs gdm ,except I ps and kill -9 gdm's pid
now /etc/init.d/xdm can't control gdm. but it could last week

and there was no " /run/gdm/gdm.pid no such file " info last week

Hi,

I had the same issue, the quick and dirty fix is to create a symlink from /run/gdm to /run (where you can find the file gdm.pid):

Code:
sudo ln -s /run /run/gdm

Best, Georg

thank you
It works

I was troubled by it for weeks . I had thought it was because I update some software's version ,maybe xdm or sth others , to make them not compatible .

recently I use startx instead of gdm , it works with no "crashed"

thank you again.

and I notice that the ln command had to be done every time cos /run directory is cleared every boot.

A more permanent solution that persists after reboot:

In /etc/init.d/xdm I added the following line:

Code:

ln -snf /run /run/gdm


directly after the start function is called.

Here is a code snip of the start of the start function:

Code:

......

start() {
   ln -snf /run /run/gdm
   local EXE NAME PIDFILE AUTOCLEAN_CGROUP
   setup_dm

......


After a system reboot my xdm is no longer flagged as "crashed", I was able to confirm this worked on both my laptop and desktop installations.
