When I start up Ubuntu 16.04 some applications take too long to run the first time I open them, including Chrome and any PDF viewer. Others, like nautilus, start up immediately.
The first time I try to use a PDF viewer like okular, it takes too long to open. After it opens a PDF file for the first time, other files open quickly. Even if I close all and open some after a long time, it happens quickly.
How can I speed up these programs opening on the first run?
I got the same problem out of the blue on my new notebook. After that I did a new ubuntu installation on a desktop machine, and the problem didn't happened there.
After some research, I found the solution here on the Arch Linux Forums
Close all your apps (like Chrome) and try running the following command on a terminal:
gnome-keyring-daemon &
After that, open Chrome again. It might ask for your account password again once. For me this solves the delay problem. Chrome and gnome-terminal are opening very fast now (< 1 sec delay instead 30 sec delay).
For you knowledge, Chrome was throwing the following error before this fix:
Gkr-Message: secret service operation failed: Did not receive a reply.
Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.
I logged Chrome startup with strace, and this message alone took 25 seconds to appear. I guess this is a system message, not only for Chrome, because I was having the same issue with gnome-terminal starting up as well, and this fix solve that issue too.
gnome-keyring-daemon already running. This answer helped askubuntu.com/a/911755/61218
You could install preload and ureadahead and see if that helps.
Both can work together as far as i know - so they shouldnt conflict with each other.
preload is an adaptive readahead daemon that prefetches files mapped by applications from the disk to reduce application startup time.
See its man page for more.
You could install preload via
sudo apt install preload
ureadahead (über-readahead) is used during boot to read files in advance of when they are needed such that they are already in the page cache, improving boot performance.
Install it via
sudo apt install ureadahead
While ureadahead is most likely installed already anyways.
I seems that the bug is caused by the dbus-user-session package (see https://bugs.launchpad.net/bugs/1689825), which prevent gnome-keyring-daemon from starting.
Uninstalling dbus-user-session can fix the problem.
sudo apt-get purge dbus-user-session
