Brightness not changing and desktop icons not showing randomly

ng flag

Sometimes after I login, brightness controls don't work neither on keyboard nor from settings and notification area; but I can change it using xbacklight.

I've noticed every time this happens, desktop icons also don't show up. Changed desktop icons to nemo, still have the problem, but icons load after changing displays (external only, built-in only, ...)


Notice that this does not happen all the time, but it happens frequently, and (from my perspective) randomly. (so not a duplicate question!)

I've searched and read a lot, but couldn't find the cause, and the only solution for me (beside using xbacklight and assigning a key combination to it) is to logout and login again and hope for it to work.

Any solution, suggestion, clue, and having the same problem is appreciated :)

Hey Hossein Shojaeifar! I suggest you to ask this question in [unix.se]. Zorin OS is off-topic in Ask Ubuntu. Read this [help/on-topic] article for more information.

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.
