Install the xf86-video-ati package and then create a file called driver-radeon.conf in

/usr/local/etc/X11/xorg.conf.d

and put these lines in it

Section "Device"
Identifier "Card0"
Driver "radeon"
EndSection

then put this line in /etc/rc.conf

kld_list="radeonkms"

Then the radeon driver should be used

It looks like your card is unsupported on FreeBSD11 which GhostBSD is based on.

Try using it on TrueOS which is based on FreeBSD12. Apparantly it's quite stable. Or if you know your way around FreeBSD you can try it on FreeBSD12.

You also probably also need the graphics/drm-next-kmod port and the xf86-video-amdgpu driver (also port only) which are both only available on FreeBSD12 with src installed.

Have a look at this:

For what it's worth I'm using an R9 270 with radeon drivers and it works quite well.

I have a usb key with true os instaled and the brightness work . but true os is not a good bsd .

No, it isn't yet. But it's improving every day. GhostBSD 18 will be based on it.

I have a machine with FreeBSD 12 and it has run fine so far. Very stable.

Hopefully soon the amdgpu driver and drm-next-kmod will be available in FreeBSD/GhostBSD 11 soon.

I created two brightness scripts for the hotkeys

/bin/bsd_brighter.bash

Code: Select all

#!/bin/bash
export value=`sysctl hw.acpi.video.lcd0.brightness | awk '{ print $2 }'`; if [[ ${value} -le 90 ]]; then sudo sysctl hw.acpi.video.lcd0.brightness=$((${value}+10)); echo "${value}"; fi

/bin/scripts bsd_darker.bash

Code: Select all

#!/bin/bash
export value=`sysctl hw.acpi.video.lcd0.brightness | awk '{ print $2 }'`; if [[ ${value} -ge 10 ]]; then sudo sysctl hw.acpi.video.lcd0.brightness=$((${value}-10)); echo "${value}"; fi

# Add your user to the wheel group in /etc/group like this

Code: Select all
