Well, I think I have more info.
I had a look at the X log file and it is pretty clear that the (default) Radeon is present but does not “load” or activate etc.
The AMD instructions in the release notes indicates that this driver should (must?) be uninstalled before attempting to install any other follow-on driver.
The newer Catalyst driver instruction indicates to un-install the driver by running their own un-install shell.
“aticonfig --uninstall” or sh ati-driver-installer-x86.x86_64.run --uninstall
Neither of the above worked (of course) Then they suggest as a last choice to use Yast to uninstall the (driver) RPM. Which DID work.
Since it was installed but not loaded. it didn’t change anything (display-wise) either.
In following the instructions, they then suggest to go to the /etc/X11/xorg.conf.original-* file and copy it ‘over’ the current one.
This is where I might be at a learning curve. I couldn’t find the file. at least in the format they indicate in the instructions.
I DID find the following in /etc/X11/xorg.conf.d
Is this a new format for conf files? (I confess, I haven’t been studying the release notes for opensuse versions) Instead of 1 big config file, several (specific) small ones?
I am guessing that since I actually didn’t load an ATI driver and then go back to a default or previous driver , I didn’t appear to generate any “conf.old” files.
It appears that I can just continue following the AMD instructions above for the “11.11” driver carefully.
There’s an easier way to install it - using the ATI repo referenced in
the wiki. That’s how I installed it - but I’m probably going to have to
try an older version.
I am not sure that the repo mentioned has the latest driver (11.11) Maybe no one has built the RPM yet?
