[SOLVED] Grub freeze after Catalyst install

Question

Hello guys,
I tried to switch from free to proprietary driver (Catalyst) but, despite I set the option nomodeset in the grub, the shell is frozen and I can't access anymore to my system.
How can I install again the free driver and be again operative?
Thanks.

Answer 1

Sorry If I answer now.
And yes, I run the command
sudo aticonfig --initial
and installed the correct version of Catalyst, not the legacy because I have an ATI Radeon 5650.
I chrooted, removed the Catalyst, installed again the open source driver but nothing, the process is blocked after some seconds I select the GRUB voice and starts to charge the modules.
How can I ripristine again the previous configuration?
I am lost now.
One thing more.
I noticed that, despite I removed Catalyst, when I run
atinconfig
still works, it is not saying that is not in the system anymore.
And this is strange.
Update:
as you requested, I try to explaine better what I exactly did.
I start from a system with the open source driver (xf86-video-ati). Yesterday I decided to switch to the proprietary for gaming reasons.
Then I followed the wiki:
I added the repository of Vi0l0, updated pacman and then:
sudo pacman -S catalyst-hook catalyst-utils catalyst-libgl opencl-catalyst lib32-catalyst-utils lib32-catalyst-libgl lib32-opencl-catalyst
The installation seemed to go correctly but maybe an error could have come here, I am not sure.
The I run:
aticonfig --initial
blacklisted radeon editing the file
sudo nano /etc/modprobe.d/modprobe.conf
adding the line
blaclklist fglrx
and I checked into the directory /etc/modules-load.d/, there it was a file called aticonfig with a single line containing fglrx .
I rebooted my system, adding the option nomodeset in the linux line of my crug configuration and since then it froze.
The system starts to load but after few processes the cursors stops to blink and then it is blocked.
I remember that it happens after it is loading some video driver regarding screen backlight.
I also noticed that when I chroot and then start an X session, it is unable to start it, so there is an error in the video driver.
Now my target should be to ripristine the previous open driver.
Then I removed Catalyst but still aticonfig is working.
What shall I do?
PS.
Going back from work, later today, I will post my xorg.config file.
