[RESOLV] Driver xorg-xf86-video-ati doesn"t work for me

Hi,

I have a RADEON HD 7470M

01:00.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI Caicos [Radeon HD 6400M/7400M Series]

SliTaz 3.0 run perfectly but my screen resolution is blocked at 1024x768 [use VESA], and when use radeon driver, xorg doesn't work.

SliTaz 4.0 display a black screen with default vesa driver

SliTaz rolling seem version 3.0 (resolution blocked at 1024x768)

My laptop have intel i3-2350M (Intel® HD Graphics 3000 was integrate in processor).

I run tazx and choose ATI

Xorg config files for two screen

screen0 for ATI Card (driver radeon)

screen1 for Intel HD Graphics 3000 (driver vesa)

EDIT:

I check dmesg.log and found

[drm] radeon defaulting to kernel modesetting.

[drm] radeon kernel modesetting enabled.

It's seem need firmware CAICOS for my radeon card

EDIT:Resolv

[c]# tazpkg install firmware-radeon[/c] (include CAICOS firmware)

[c]# rmmod radeon[/c]

[c]# modprobe radeon[/c]

[c]# depmod -a[/c]

Work perfectly

Re: [RESOLV] Driver xorg-xf86-video-ati doesn"t work for me

Slitaz iso only includes the VESA driver for ati/amd g.p.u.

None of the tazpkgs required for ATI KMS are included unless the package includes files necessary for Intel KMS.

Use boot option [c]sound=noconf[/c] on rolling to override soundconf freeze, report back if your sound works.

Re: [RESOLV] Driver xorg-xf86-video-ati doesn"t work for me

well, as far as vesa refuses to load if there is a kernel module bounded to video card  this does not make much sense if module radeon is auto loaded by kernel, how are users supposed to avoid video modules loading at boot?

maybe kernel video modules should be putted in a linux-video package not inluded in live iso?

Re: [RESOLV] Driver xorg-xf86-video-ati doesn"t work for me

Mojo, thanks for sound=noconf option, boot not freeze, and my sound card work

For Radeon KMS support

1/ I install xorg-xf86-video-ati and firmware-radeon.

2/ In TTY1, i execute rmmod radeon && modprobe radeon && depmod

3/ I modify /etc/X11/xorg.conf.d/60-screen.conf and change vesa for radeon

4/ In TTY1, i execute /etc/init.d/slim restart

Now my resolution is 1366x768 with radeon driver and KMS
