I followed the tutorial to set up Xorg, but i have a little trouble.

From xorg.log...
Code:

[KMS] drm report modesetting isn't supported.


and dmesg...
Code:
[drm] radeon kernel modesetting enabled.


Maybe i should just install uvesafb and don't bother...?

dmesg http://pastebin.com/mEPkwpqM
Xorg.log http://pastebin.com/ckRxsZdY

Jozpod,

Make friends with wgetpaste and put your kernel .config onto a pastebin please.
Post your lspci output too.

Use whatever driver you want.
It will be like keeping a Ferrari just to drive to the corner shop - but its your Farrari.

Is radeon a module or builtin ?
If it'a a module, firmware needs to be installed where kernel can find it.
If it's builtin, firmware needs to be in the kernel too.

:roll: Also, if 'radeonfb' in dmesg refers to CONFIG_FB_RADEON, then you somehow managed to find a significantly outdated guide (or didn't read it right).

I looked for similar problem...
https://forums.gentoo.org/viewtopic-t-950682-view-previous.html?sid=6f4bb614f7d6e493bf17720ed8a995ab

and looks like i set two framebuffers...

Anyway, here is the paste of old config and lspci. New kernel on the way...

Jozpod

You have two video drivers in the kernel and they are fighting ovor the hardware
Code:
CONFIG_DRM_RADEON=y
...
CONFIG_FB_RADEON=y
CONFIG_FB_RADEON_I2C=y
CONFIG_FB_RADEON_BACKLIGHT=y


The kernel part of the Radeon driver CONFIG_DRM_RADEON, give you a framebuffer console for free. CONFIG_FB_RADEON must be off.

Finally it shows something meaningful in /proc/fb :
Code:
0 radeondrmfb


Thank you!
