Set-up
I'm using Fedora 31 on a notebook without any display attached. (I got this notebook for free, because the display was broken and I still use it as a server for various tasks).
Furthermore, I'm using a wifi USB dongle because I accidentally cut through the onboard wifi antenna. If I need to get work done, I connect using ssh or vnc.
Description
After upgrading from Fedora 30 to 31 I noticed that after a while I wasn't able to connect via ssh anymore. I figured this might be related to power/energy settings.
So, I connected with vnc and toggled the following setting:
At this point, I got disconnected immediately and I haven't been able to connect properly every since.
At first, I attached a display of mine, but after the Fedora bootscreen, no desktop was shown. As a result I plugged my Ethernet cable in and wanted to check what was wrong by means of xrandr. However, this command only returned Can't open display.
I then went ahead and tried reactivating my WiFi by means of nmcli and discovered the following:
- After the boot, I have to execute
sudo rfkill unblock wifi - Afterwards, I need to activate it via
sudo ifconfig <wifi> up - Now,
sudo iwlist <wifi> scanshows my SSID again. (nmcli dev wifi list is empty though…) nmcli connection up id <SSID>returnsError: Connection activation failed: No suitable device found for this connection (device <wifi> not available because device is not available)
This question describes my problem, but the solution does not work for me.
