I dont like Microsoft operating systems and wanted to try something different. I installed Linux. The installation process was very painful. Getting it to cooperate with the hardware was worse, and of course there is no real support. I finally got it halfway working. At that point, I found it was hard to learn, harder to get used to, and hardest to do anything useful since none of the programs were familiar. Two days…
I've been using linux for over a decade and never even _heard_ of this or something similar happening. AFAIK the only typical way to configure these things is through the BIOS, well below the OS level. It sounds like something got borked and the computer repair shop decided it was easier to blame linux than to figure out or explain what happened.
Or they decided this was an opportunity to make an easy sale of some replacement hardware.
