Seems like the God of Tech took a break and then resumed smiting me. This time, it's my monitors that were afflicted.

I have a dual-monitor system here, two fairly similar monitors but one was connected via HDMI and the other was connected via VGA. After restarting after a system upgrade (nothing that I deemed unusual at that time anyways), the monitor connected via HDMI stopped working. Worse, the remaining monitor started behaving weirdly. A bit confused and a bit rattled, I started changing things at random, switching cables around, turning off one monitor, turning the "working" monitor on and off again, and lost track of which changes led to which behavior. This has gone on for a good eight to twelve hours.

In the end, I asked someone for help, which turned almost disastrous. Both monitors stopped working almost for real. It turned out that a change in configuration made things worse, and all I had to do to gain some semblance of proper operation (sans one monitor) is to disconnect the supposedly broken one. It also turned out that my computer recognizes that the broken monitor is connected to it (when it actually is), but it doesn't know what to do with it, and thus explains the weird stuff happening with my display.

Long story short, I might need an exorcism, lol! Exorcism muna kasi mejo kulang sa pera pambili ng bagong monitor at possibly video card.
