How do I set the 'video.allow_duplicates=1' parameter?
by IOACHIMVS from LinuxQuestions.org on (#56B5W)
Hello there,
I'm running Debian 10 Buster on my laptop, and I notice that waking up after a suspension all goes right but a dialogue from XFCE shows up asking me to setup the "new screen" (no other than my laptop's monitor).
Rather than trying to disable that dialogue I've checked systemd's journal in order to know what's going on, and I have found this line, not after the suspension wake up but at the boot of the machine:
Code:Firmware Bug]: Duplicate ACPI video bus devices for the same VGA controller, please try module parameter "video.allow_duplicates=1"if the current driver doesn't work.Assuming that my screen is being detected twice and it's de ACPI's video module I tried making a .conf file at /etc/modprobe.d/ but it seems not to work, probably because of a bad syntax. How should I do so?
I tried with this:
Code:video video.allow_duplicates=1then:
Code:options video video.allow_duplicates=1Does the name of the file matter? I named it 'acpivideo-duplicate.conf' if you're asking.
Thanks in advance.
