I haven’t been able to give this project 100%. It’s not complete as yet, so, I thought I would post a progress reports :-
My PC had a partition with Leap 15.5 loaded. As an experiment, I installed the RTAI 4.19 kernel onto it. Initially, I thought I had done something wrong, because it booted with the Debian splash screen, but it did boot as 15.5. It was not happy. Applications like Dolphin were struggling, networks not working correctly… I didn’t bother looking at any logs, thinking there would nothing I could do with what I’d find.
I then used Gparted to remove that partition, and installed Leap 15.1, via USB ISO. It went well until I got to the point where it asks to setup the network. This machine doesn’t have Ethernet (it’s too far away from a port), it uses a USB WiFi dongle (RT5370), about 5-6 metres from the access point (works well with Windows, Debian and Leap 15.5). I couldn’t get Leap 15.1 Setup to connect, so, I allowed it to install via the ISO, and I would do an update later…
It seemed to install okay. About 1/3 through the update it froze, and I had to use the power switch. I tried it again, and it froze again at about the same place.
The WiFi signal strength was showing 65%, this was not right, I was guessing that the RT5370 driver was bad, and that an update may install a better driver…
I found a powered USB hub with a 5metre lead, so could get the antennas very close – it went from 65% to 85%, but enough to allow the update to complete. Unfortunately, the WiFi didn’t improve.
But another problem came up – after around 3-4 minutes of On time the machine would just switch Off, without warning. It was like the power supply in the machine had gone faulty. It was working okay with either Windows or Debian running. I then noticed when I turned the machine back on immediately after it shutdown, the BIOS settings were showing the CPU core temperatures at very high (over 100’C), but cooling down. Using ‘sensors’ under Debian the cores were about 55’C.
It was tricky with a very limited On time to install sensors into 15.1, but when I did, it was showing rubbish – one core at -17’C, another at +21’C… It was time to get Gparted out again…
With the better WiFi signal things went better this time. I have managed to do the updates, but the WiFi is still not good…
I see on the web that there are several replacement drivers for the RT5370, but these are focused on the Debian Raspberry Pi.
Does anyone have a suggested replacement?
Can I find and install the 15.5 driver?
