in the last few weeks, I’m facing up a very strange issue with my Antergos KDE OS.
When at home, everything works fine with and without Internet connection.
As soon as I connect the PC to my office network I get long delays (30s or more) in loading a few applications. I have this issue with LibreOffice, Thunderbird, VMWare Workstation Player, etc.
When connected to office network, I’ve also noticed a long delay when I use Okular to print a file (Okular loads very fast but, as soon as I ask to “Print”, I have to wait 30s or more before to get the “Print — Okular” window).
There other apps, e.g. GIMP, that work always fine. GIMP loads always very fast and no delay issue with printing.
Before getting this issue, I worked a few months in the office without any issue when connected to the network. It’s about 2 months that I’ve this delay issue. I’m not aware of any change in the office network. I don’t know whether the issue started after installing new packages or after some package upgrade.
In the last few days, supposing that it the delay was an issue with “QT printer discover”, I’ve played with avahi-daemon configuration (“use-ipv4=no”,
“use-ipv6=no”) and tried to set “QT_DISABLE_PRINTER_DISCOVERY=1” but no results at all.
I have no idea what I should look at to understand more and fix the issue.
Thanks in advance for your support,
