Subject: kernel: lightdm-gtk-gre segfault at 0 ip
Hello everyone,
I use tigervnc and lightdm on two CentOS 7.4 servers. The following packages are
installed:
kernel: kernel-3.10.0-693.17.1.el7.x86_64
lightdm-1.18.3-5.el7.x86_64
lightdm-gobject-1.18.3-5.el7.x86_64
lightdm-gtk-1.8.5-19.el7.x86_64
lightdm-gtk-common-1.8.5-19.el7.noarch
tigervnc-license-1.8.0-2.el7_4.noarch
tigervnc-server-1.8.0-2.el7_4.x86_64
tigervnc-server-minimal-1.8.0-2.el7_4.x86_64
One is workering for more than one year .
The 2nd one also. but yesterday I have to reinstall it because one disk is
failed and changed. After the installation, I believe I did the same
configuation, but the 2nd one is not working. The VNC connection is just showing
a black screen, then close.
I see the following error logs:
lightdm[32702]: g_object_unref: assertion 'G_IS_OBJECT (object)' failed
lightdm[37158]: pam_unix(lightdm-greeter:session): session opened for user
lightdm by (uid=0)
lightdm[32702]: Error activating login1 session:
GDBus.Error:org.freedesktop.DBus.Error.NotSupported: Operation not supported
kernel: lightdm-gtk-gre[37161]: segfault at 0 ip 000055fa326fc710 sp
00007ffd011f8fc0 error 4 in lightdm-gtk-greeter[55fa326f2000+13000]
The last line above, looks like something related with kernel?
I really lost. Please let me know if you need more information for my problem.
Thanks in advance!
