Merde alors! Failsafe ... I remember that from my SuSE past ... :-)

I have no idea ... it worked ok for quite some time now and I never
changed the initial configuration and the last re-installation of the
driver because of a kernel update was some time ago. It simply came out
of nowhere, so I think it came with some security update I did.

It must have come to the market sometimes in the first half of 2011 and
is marketed only as OEM for computer manufacturers (machine is a Lenovo).

I tend more to using a different version of the nVidia driver.
Originally the nouveau driver was installed with Kubuntu, but it never
could bring up a decent resolution.

Will do ... thanks for pointing at some solutions!
Talk to you later ... Hans (54 to go)
