screen brightness suddenly dimmed and now won't go above 50%

in flag

I was just working on my computer doing nothing particularly interesting and my brightness suddenly dimmed and won't go back up above 50%. I can control the slider and I tried manually adjusting with echo x | sudo tee /sys/class/backlight/intel_backlight/brightness but anything above 5000 or the halfway point on the slider just doesn't get any brighter. Restarting doesn't do anything either. It could be a hardware issue but since I'm not dual booting I can't think of a meaningful way to test that, has anyone had this problem?

I am assuming this is a laptop? There is probably a key combination to adjust the display brightness.

@Nmath yes there is a key combination which does work to control the brightness but not above 50%

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
