I have just installed OpenSUSE TW a few days ago and whenever I start some programs they take atleast 30 seconds to start. Firefox, thunar, and flameshot are the applications I’ve experienced this issue with. Alaritty, xterm, and emacs does not seem to have the same issue.
What could be the reason?
Some technical info:
TW version: 20221215
WM: dwm
How much memory and what CPU
When you start “firefox”, it has a lot more code to load. And then it looks through cache, probably builds a cache directory, before it can get started. Simpler applications such as “xterm” don’t have to do that much work.
I haven’t timed “firefox” here, but it does take a while when first loaded. For me, the slowest is “virt-manager” which takes several minutes.
32 GB RAM
i7-10750H 6 cores
If I strace firefox it stops and polls for ~20 seconds before continuing.
Can you share the log (with timestamps) via SUSE paste?
With this hardware I see no reason for any delays . Maybe a DSN Issue???
What log are you referring to?
@malba I suspect @gogalthorp is referring to the strace output.
In firefox settings, check the proxy setting and disable.
Are you using you ISP DNS servers, or a third party one (google, openDNS etc).
Firefox is the only application from the ones you are mentioning which I use as well and on one of my machines I sometimes (usually after a Tumbleweed update) see a similar delay on Firefox start up as you do.
Searching the internet for quite a while I found
zypper in -f gsettings-desktop-schemas
should help (some GTK3 problem?).
I tested it and it did indeed remove the startup delay.
Maybe it’s worth trying …
I think the problem might have something to do with the display manager. If I try changing from “console” (where i started X11 with startx) to SDDM described in this guide, I get put straight into DWM and all applications seems to start with no delay.
Now how do I resolve this issue where the display manager does not start?
What log are you referring to?
The strace log you mentioned in the reply above.
Timing Firefox is straight forward. It runs in the app slice. Startup takes some five cpu seconds :
