gdm-3.18.2 screen flicker
 
I try to build GNOME base on these
LFS : Version 7.9-systemd
BLFS : Version 2016-03-22 (systemd edition)

All GNOME version 3.14.x and 3.16.x change to 3.18.x
and using GDM-3.18.2 as display manager.

When I tried to start GDM
Code:
systemctl start gdm
screen keep flickering, and no graphical login screen.

Try to check status
Code:
# systemctl status gdm
● gdm.service - GNOME Display Manager

I had similar problems with gdm for systemd. It compiled correctly but would not launch. You can try the command
Code:
journalctl -b
to see if there is any clue why it doesn't start. The solution for me was to use lxdm. Inside this thread, one of the responders provides a link on how to compile lxdm for systemd. I am an xfce user, but you can use lxdm as a login manager to launch any desktop environment.

I had to rebuild Polkit and Polkit-gnome to get GDM to work.

Installing lxdm using this options:
1. Pam lxdm
Code:
auth      substack    system-auth
auth      optional    pam_gnome_keyring.so
account    include      system-account
session    optional    pam_systemd.so
session    optional    pam_keyinit.so force revoke
session    include      system-auth
session    optional    pam_gnome_keyring.so auto_start
2. configure options
Code:
./configure --prefix=/usr                                  \
            --sysconfdir=/etc                              \
            --with-pam                                      \
            --enable-gtk3                                  \
            --disable-consolekit                            \
            --with-systemdsystemunitdir=/lib/systemd/system
LXDM can load GNOME :-(

Those are the same entries I used.

I used the config options mentioned in the link, a little bit different from yours. Looks like you figured it out yourself. As long as it works, that's all that matters. In addition, I had to put the following info in ~/.xinitrc
Code:
exec dbus-launch --exit-with-session startxfce4
export $DBUS_SESSION_BUS_ADDRESS

It should load them all. I use it to load xfce, fluxbox, openbox, sawfish, and icewm. Anyway, looks like you got it to work.

--------------
As a follow up to gdm, I recall from the link I provided that gnome-session is one of the requirements for gdm. I could not get gnome-session dependencies to compile. In addition, one of the posters mentioned that gdm does not work with the proprietary nVidia driver. I prefer to use the proprietary driver. Hence the reason I decided to stick with lxdm.

anak_bawang 07-21-2016 08:24 PM
After one and half hours googling

1. First fix permission of gdm
Code:
# chown -R gdm:gdm /var/lib/gdm > /dev/null
# chown root:gdm /var/log/gdm > /dev/null
# gtk-update-icon-cache -q -t -f /usr/share/icons/hicolor
2. Start gdm, and see the journal log
Code:
# journalctl -b
...
/usr/bin/gnome-session: line 15: /libexec/gnome-session-binary: No such file or directory
...
3. Edit /usr/bin/gnome-session script file
Change this line : exec ${exec_prefix}/libexec/gnome-session-binary "$@"
With : exec /usr/libexec/gnome-session-binary "$@"

4. Start gdm, it works. I can login to gnome. After logout, I can not re-login. Need to reboot :-(

5. Try with LXDM

Try to load icewm (I had to built it to test LXDM), it is okay.

Now trying to load gnome with LXDM.
Error, and the message on screen is
Code:
Oh no! Something has gone wrong.
A problem has sccurred and the system can't recover.
Please log out and try again.
Click logout, back to login screen.

6. Another problems, not found solution yet. Any suggestion, please.

i am not a gnome user so I can't replicate the error. Does lxdm load fluxbox? I notice your lxdm config options are different from the BLFS documentation.

Yes, it can load fluxbox, IceWM, openbox, sawfish.

plasmonics 07-25-2016 07:19 AM
Regarding the error "A problem has occurred. The system cant recover ...", I faced something similar trying to launch xfce4 from lxdm. After at lot of googling, I had to add two lines to ~/.xinitrc. (See post #8). Could a similar fix be required to launch Gnome?

anak_bawang 07-25-2016 08:46 PM
No. It does not work :-(
