I am new to Linux and I am using Debian Testing with KDE Plasma installed during the installation process(i.e. tasksel).
I had a problem with my brightness controls (the Fn keys or the brightness slider was not working too) so after googling I finally got a solution. And that was to create a file
/usr/share/X11/xorg.conf.d with some text in it and after a reboot the Fn keys and slider started working/changing the brightness.
But I noticed an issue after doing this: After login when the KDE Plasma Splash screen started flickering after the loading(circling) was over and even the kde application launcher, the panel started flickering when I hovered mouse on them (but a little fast).
So I removed
20-intel.conf file, rebooted and all the flickering stopped. But I need to change the brightness too. Also the brightness file in the
4422465 which seems strange to me. Also there is another folder named
/sys/class/backlight but its brightness file has value 7.
So how do I enable brightness control as well as fix the flickering issue too?
Does it have something to do with the
acpi_video0 folder or do I need to add its conf file and if yes what should it contain...
Thank You in advance..!!!
