Ever since installing lightdm to fix the login password loop issue, I receive a popup asking me to authenticate from everything to wifi scans, to color profile, to refresh system repositories. I've tried dozens of different guides, advice, and nothing seems to work.
This problem started when I followed this answer and changed my /etc/default/grub file by modifying the GRUB_CMDLINE_LINUX_DEFAULT
from "quite splash" to "nomodset", then installed lightdm. I reverted it back to it's default value of quiet splash acpi_backlight=vendor
. I also tried changing the permissions of the .Xauthority file, but that didn't work. Also, my brightness buttons seems to be screwed up in that I have to hold them for very long before I notice the brightness changing.
I just want to stop the popup that asks me to authenticate for everything, and am hoping the community here has some advice.
lightdm
would be helpful anyway using standard repository software.... ie. there are holes possibly you should fill to your question that may help get useful answers.
