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 (IntelĀ® 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.
