KMS + Radeon quick mini guide

[legume]

Bleh, updated xf86-video-ati from git today, and X doesnt start anymore.

You need to update libdrm and then rebuild xf86-video-ati.

You need an updated libdrm, otherwise you will get an unresolved symbol.

The only problem is that you might end up with a blank screen if you forget to load fbcon (the framebuffer console).

This is exactly the reason why I compile everything into the kernel.

Why should I have to remember to load the framebuffer console?

[Kurko]

Console works well in full resolution with KMS but when I start Xserver it freezes. Graphic adapter is Mobility radeon HD2600.

Xserver output:

rebuild the 3 libdrm, xf86-video-ati , mesa again from git in the correct order
and git pull them beforehand

[netkas]

yeah, figured, just reinstalled lbdrm and video-ati from ppa.


Is there any way to fix such incompatible problems durring configure.sh stage ?

like, if version of libdrm isn't decent - ask for update.

[Kurko]

I rebuilt libdrm, xf86-video-ati, mesa from git but I still get same error

[agd5f]

Make sure you updated your libdrm tree properly. Here is the relevant commit:

[Kurko]

I copy /usr/local/lib/libdrm.so.2.4.0 to /lib and now this works perfectly

[hmmm]

What demo's are you using to check shader performance?
