Firefox 40+ slow right click in Debian Linux

Just installed latest firefox on debian linux streetch.
Right click on link popup very slow.

SOLVED: [blfs-support] Firefox – slow menu and right-click response

The right click menu in Firefox is now fast again. I disabled Pulseaudio which
tried to load ConsoleKit. This did not work sine I have unstalled ConsoleKit.

=== details ===

I found this:

/var/log/sys.log
Jan 25 09:13:47 lfs pulseaudio[2565]: [pulseaudio] module-console-kit.c:
GetSessionsForUnixUser() call failed:
org.freedesktop.DBus.Error.ServiceUnknown: The name org.freedesktop.ConsoleKit
was not provided by any .service files
Jan 25 09:13:47 lfs pulseaudio[2565]: [pulseaudio] module.c: Failed to load
module “module-console-kit” (argument: “”): initialization failed.
Jan 25 09:13:47 lfs pulseaudio[2565]: [pulseaudio] main.c: Module load failed.
Jan 25 09:13:47 lfs pulseaudio[2565]: [pulseaudio] main.c: Failed to
initialize daemon.
Jan 25 09:13:47 lfs pulseaudio[2562]: [pulseaudio] main.c: Daemon startup
failed.

I commented out the text below in /etc/pulse/default.pa
#.ifexists module-console-kit.so
#load-module module-console-kit
#.endif

I restarted and then the problem with the Firefox menus disappeared.

The root cause is probably that I uninstalled ConsoleKit. This was
intentional, but I failed to recognize the side effects.

Centos 6 No package php-fpm available

After installing epel and remi repository and enable remi-php56, the php packages still not available. The issue is i just uninstall Cpanel from my Centos 6 server. Cpanel disable php packages from showing up in you


#vim /etc/yum.conf
[main]
exclude=php* ..

Just remove php packages from the exclude section of the /etc/yum.conf

It waste 3 hours of my time to figure this out.. 😦

powerdns unable to find backend willing to host for potential supermaster

I got this error when i setup powerdns superslave in debian using sqlite3 backend. The condition to get the superslave working.

  • The supermaster must carry a SOA record for the notified domain
  • The supermaster IP must be present in the ‘supermaster’ table
  • The set of NS records for the domain, as retrieved by the slave from the supermaster, must include the nameserver that goes with the IP address in the supermaster table

A very usefull command to test if the setup is working

to send the notification to the slave and
#pdns_control notify mydomain.com

to request for supermasters zone
#pdns_control retrieve mydomain.com
