Unable to run System Log on Ubuntu 16.04 LTS

  • 772

I am having a difficult time to run syslog GUI. I added a new filter in the System Log. What I did is: click the button at the top right of the GUI window (the button with a gear icon). Then, click the menu item filter-> New -> filled with a filter name (the filter name is words with a space character separated)and a key word of the log I would like the see -> click ok to finish to create the filter.

After that, the system log crashed. Since then, I could not run the syslog gui anymore. Every time I try to start the application, it automatically closed directly.

Here is the log file content related the syslog. It seem KLogPermitNonKernaelFacility is unable to run. Anyone knows how to fix the problem?

[Edit 2.1] After I use:

tail -f /var/log/syslog

I found everytime I try to run syslog, the kernel gives me:

traps: gnome-system-lo[20589] trap int3 ip:7f83223aba6b sp:7ffc2e3b3730 error:0

[What I tried] I tried to uninstall rsyslog and reinstall

apt-get autoremove rsyslog

and then do

apt-get install rsyslog

[Edit 2] Did an uninstall with purge as MicroParsec suggested. Still unable to start the log application

[edit 3]

After edited sudo gedit /etc/rsyslog.d/50-default.conf

from

daemon.*;mail.*;\
    news.err;\
    *.=debug;*.=info;\
    *.=notice;*.=warn   |/dev/xconsole

to

daemon.*;mail.*;\
    news.err;\
    *.=debug;*.=info;\
    *.=notice;*.=warn   
#|/dev/xconsole

The kernel still spit gnome-system-lo[21384] trap int3 ip:7f817444aa6b sp:7fff2713fb00 error:0 and refuse to start syslog viewer.

Thanks in advance.
