I decided to try, once again, to move from the open source radeon driver to the proprietary fglrx driver. This did not went very well

Following the directions in here, here and here, I configured the kernel accordingly, changed the variable VIDEO_CARDS in make.conf and updated the system:

# vim /etc/make.conf
VIDEO_CARDS="fglrx"
$ sudo emerge --update --newuse --deep world -av

The problem is that, when loading the fglrx module into the kernel, I get an error saying “no such device”. As stated in here, when this happens it probably means that your video card is not supported by the driver. So there is not much to do.

My video card is a Mobility Radeon X1600, and my ati-drivers ebuild shows version 9.11. I went to the ATI page, http://support.amd.com/us/gpudownload/linux/legacy/previous/Pages/radeon_linux.aspx, and chose Catalyst 9.1, which I think is the one I installed. Well, in the Release Notes pdf, my video card shows as being supported by the driver. So…I just don’t know…
