Dear all,
In case anyone experiences problems with Alma Linux, NVIDIA graphics
boards and the NVIDIA graphics driver, here is what worked:
somehow, the nouveau graphics driver seems to sneak back in, even if
blacklisted. When nouveau is in use, the ugly graphics are obtained with
ccp4mg.
There are several procedures mentioned on the web to install the NVIDIA
driver.
This one worked,
https://www.linuxcapable.com/how-to-install-nvidia-drivers-on-almalinux/
. All the nvidia or cuda packages installed by any alternative procedure
must be removed first.
The other approaches mentioned on the web didn't work in my hands (and
led to big problems).
The procedure mentioned in linuxcapable seems to set SecureBoot on, and
then this HP Z4 computer doesn't boot any more. One has to enter the
BIOS and have "Legacy support enable, Secure boot disable" set (and saved).
Just in case.
Fred.

Dear all,
Perhaps a reader of the bb will have a solution for this problem. ccp4
is version 8.0 and is up to date. All graphics programs (coot, but
also other non-ccp4 software such as chimeraX, Pymol...) run fine on
the Alma-Linux 9.3 system. There is a problem however with ccp4mg: the
images appearing on the screen are... wrong and quite useless (see
enclosed png screen capture). There is no error message at program
startup.
I have disabled and blacklisted the nouveau graphics board driver and
installed the NVIDIA driver. Made no difference.
So has anyone seen this behaviour before and has a solution to propose?
Thank you.
Regards,
Fred.
