[SOLVED] Can not enable Radeon driver

Hello!

I've gor ATI video card:

# lspci | grep VGA
01:00.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI PITCAIRN [Radeon HD 7800]

Once I tried catalyst - it was unstable for me so I decided to use open source driver. Here is my configs now:

# ls /etc/modprobe.d/
modprobe.conf
# cat /etc/modprobe.d/modprobe.conf 
options radeon modeset=1
# ls /etc/X11/
xinit  xorg.conf.d
# ls /etc/X11/xorg.conf.d/
10-evdev.conf  10-quirks.con

As you can see there is no xorg.con file. I have catalyst removed:

# grep fglrx /etc/mkinitcpio.conf 
# grep fglrx /etc/rc.conf
# pacman -Qs catalyst

Here is installed drivers:

# pacman -Qs xf86-video
local/xf86-video-ati 1:6.14.6-1 (xorg-drivers xorg)
    X.org ati video driver
local/xf86-video-fbdev 0.4.3-1 (xorg-drivers xorg)
    X.org framebuffer video driver
local/xf86-video-vesa 2.3.1-1 (xorg-drivers xorg)
    X.org vesa video driver

Syslinux.conf fragment:

LABEL arch
    MENU LABEL Arch Linux
    LINUX ../vmlinuz-linux
    APPEND root=UUID=aa295752-aaa6-44fb-a80a-d6a20fd46db6 ro
    INITRD ../initramfs-linux.img

I was thinking about using radeon driver with late KMS start:

# grep MODULES /etc/mkinitcpio.conf 
MODULES="dm_mod"
# grep MODULES /etc/rc.conf 
MODULES=(radeon)

initramfs regenerated

Xorg.conf.log

The problem is - there is no KMS nor powersaving available. I belive I am on vesa driver sad How to enable radeon driver to have it's benefits? I think it is not using for some reason (and if I force it by removing vesa package or creating xorg.conf I will have no X started).

Re: [SOLVED] Can not enable Radeon driver

Support for your card was added to xf86-video-ati *after* 6.14.6 was released. You need the git version of xf86-video-ati, and possibly the git version of mesa.

Re: [SOLVED] Can not enable Radeon driver

Thanks for the reply! The option 'wait for the next xf86-video-ati release' also available though I see no release schedules so it'll be hard to estimate waiting time...
