Install-configure Ati Mobility RadeonHD 5660 drivers

[Vagonini]

Hi all,
I have a fresh, (safe mode), installation of Sabayon 9 on my notebook HP Pavilion dv6 (AMD64 Quad Core Phenom, 4GB Ram and Ati Mobility Radeon HD 5660 graphic card) and i would know how to install the ati drivers, so to be able to use glx, direct rendering, opengl, etc for gaming...
This is my situation at this time,

eleuth@theros ~ $ eselect opengl list
Available OpenGL implementations:
[1] xorg-x11 *
[2] ati
[3] nvidia
eleuth@theros ~ $ cat /etc/X11/xorg.conf | grep "Driver"
Driver "ati"
Driver "ati"
eleuth@theros ~ $ glxinfo | grep direct
direct rendering: Yes
eleuth@theros ~ $

but I haven't updated my system after the first installation, because of the black screen that it would be if I did it..

Excuse my English....

ATI drivers should be installed and working out of the box! Running

Code: Select all

glxgears -info | grep GL_RENDERER


should also give you an idea on what driver that is in use. Although the cat xorg.conf variant works just as well.

What eselect is concerned you could run (from root):

Code: Select all

 eselect opengl set 2

That black screen is apparently a common problem after updates, have you upgraded the kernel? Newbie tip: Don't do it if it isn't necessary, at least until you're more comfortable using Sabayon.

You should read https://wiki.sabayon.org/index.php?title=En:Entropy#Fresh_Install_-_What_to_do.3F if you haven't. If you have - read it again!

Good luck!

 eselect opengl set 2

If you select the ati OpenGL library then xorg.conf must contain Driver "fglrx", not Driver "ati".

AMD Catalyst (a.k.a. FGLRX) closed-source driver package ati-drivers (plus the package ati-userspace in the case of SL):

Code: Select all

$ eselect opengl list
Available OpenGL implementations:
  [1]   ati *
  [2]   xorg-x11
$ grep Driver /etc/X11/xorg.conf
        Driver      "fglrx"

Open-source driver package xf86-video-ati:

Code: Select all

$ eselect opengl list
Available OpenGL implementations:
  [1]   ati
  [2]   xorg-x11 *
$ grep Driver /etc/X11/xorg.conf
        Driver      "ati"

For the open-source driver, see Getting rid of Catalyst.

To set the OpenGL library for the closed-source driver, as root user do:

Code: Select all

eselect opengl set ati

To set the OpenGL library for the open-source driver, as root user do:

Code: Select all

eselect opengl set xorg-x11

Can I install both the closed and the open drivers, then choose among them editing /etc/X11/xorg.conf ?

[Fitzcarraldo]

No, because there is more to it than just the contents of xorg.conf.

I did upgrade as wiki comand, eselected drivers and opengl setting fglrx and ati, but now I have blackscreen once again...
