You are using the fallback vesa driver btw, and probably your currently radeon driver doesn't support it ![]() It may actually be more recent than I thought.Especially for Debian, that could be an unupdated kernel issue anyway I attached my xorg.0.log after rebooting and running modprobe radeon So restarting removed the radeon stuff from modules again so modprobe command doesn't add it permanently.Ġ0:01.0 VGA compatible controller: Advanced Micro Devices, Inc. So reboot should start with radeon driver. modprobe radeon Didn't output anything and then lsmod | grep radeon returned 4 values. Okay, now that my days work is done, with the thing I needed Debian 8 for, I can now go back to changing stuff to fix the brightness issue. Now to clarify, every time I restarted with a change to acpi_backlight=* the xrandr -verbose changed Identifier, like right now it's 0x197Īnd I did make those changes in anything requiring the Identifier that I used to test, every time. So I have no clue what's breaking and where, also manually installing driver using insmod on the /libs/modules/3.16.0.6-amd64/kernel/drivers/gpu/drm/radeon.ko throws an error "insmod: ERROR: could not insert module radeon.ko: Unknown symbol in module"Ĭd /libs/modules/3.16.0.6-amd64/kernel/drivers/gpu/drm The Udev rule isn't working for me, as I've pointed out above my brightness max is 0, and current brightness is -19, and changing the value whatsoever resets it to 0, except by using udev, it doesn't change it at all leaving it -19, and I tried in udev through 8 restarts as of writing this, changing it to -20, -50, -80, 10, -10, -4, -42, -1 (I tried positive 10 just in case, and -42 was I gave up and just tried it)īoth return nothing but I did install xserver-xorg-video-amdgpu as well as followed this I have used Linux since 2010, I do know enough to get by, and know enough, to know where to look for answers, and how much to search before giving up and resorting to forums. ![]() Here's the results, acpi_backlight=vendor as I said above in my reply, created a new symlink to the asus-nb-wmi folder, acpi_backlight=native removed the link and changed nothing else in the system., acpi_backlight=none did nothing more than native.Įach reboot I tried setting brightness using xrandr -output 0x17e -brightness 0 and xrandr -output 0x17e -brightness 1 and xrandr -output 0x17e -brightness 0.2 and xbacklight -set 10 and fn + f5/f6 and manually changing the file in the /sys/class/backlight/ * filesĪs for the kernel module, I already double checked it's listed in lsmod both "asus-wmi" and "asus-nb-wmi". I do believe I told you I read from the ArchWiki article already, anywho.
