I’ve been working on an experimental internet access point for my car based on a raspberry pi that auto-joins various sundry wifi’s it can find or relaying out through my phone.
It doesn’t work right yet. But I’ve noticed something awful.
If I join it’s ESSID, then my gnome desktop FREEZES up, sometimes for two whole minutes at a time, when the internet to the AP is down. I have a clock widget in the top of my gnome desktop, and it displays seconds and the seconds stop ticking. I also have a pingtime widget and a cpu temp widget, and I know the highest temp is under 75 C when the freeze begins, and I’ve handled much higher temps before. I know that the ping stops updating as well (it normally updates every 5 seconds).
Does gnome have some sort of gnome-specific /var/log/messages general log of what’s going on and what’s failing that I could check?
I really think it’s gnome. my gui session locks up but ctrl-alt-f3 or whatever gets be to a tty that I can log into and look on htop and I don’t see anything unexpected. Firefox taking up all my ram like normal, gnome using a lot of cpu like normal, but no better details than that.
