I applied nvidia’s instructions found in your ‘here’ link, downloaded and installed the driver but it did not work.
I believe the problem to be Jad’s kernel an " 2.6.19-5-rt " which
cannot be unlocked I was informed, although the transaction proceeded after being questioned and answered ‘yes’ on things that I did not completely understand as a computerr newbie that I am.
It is not very important as I am quite happy with mesa as it is except for the wobbling windows. It seems that most people want special effects whereas I am trying to get rid of them!
If I could only ‘concoct’ a command to do so I would be very happy.
I understand that it could be done if the nvidia drivers were there. I did not have this problem before I changed to my new mobo.
Playing with the distro a window popped up informing me that I had not activated the newly installed nvidia driver. So I did follow the instructions and gave as root the command required in the terminal, I cannot remember exactly what it was, I think “nvidia-config” or something like that, rebooted and there was no window any longer!!!
So I had to reinstall. I am writing this after reinstalling.
Things are difficult in life!
