--Since shifting from windows to manjaro, I have a problem with screen dimness. The solution to this is covered in manjaro wiki>hardware>screen brightness too dim.The one line command solution is
sudo sed "s/(GRUB CMDLINE LINUX=)""/\1"acpi osi=Linux acpi backlight=vendor"/"/etc/default/grub -i
This brings up
sed -e expression #1, char 70: unknown option to 's'
How do i get past this ?
Is there a simpler command line that achieves the same thing ?
Total noob here , so plz keep it simple.
Tips for posting
Use a "keyword search" to make sure your question has not already been asked. For example "failed to verify key" or "sound is muted".
Make sure you include enough detail so people know what you are running. A useful command is
inxi -Fxz; copy and paste the text and format as "code" (e.g. use the </> button above).
If possible, paste text rather than upload a photo. Text is easier to read, searchable, and takes up less space on the server. Please don't upload high-resolution photos.
