downgrade - may be. I use 18.104.22.168 kernel.
By the way I have another Slack11 box with another Ati card and it runs fine -for now
. But I can't get a new card.
And you say this is a driver problem? not x.org's? But There are other big distributions that use x.org 6.9 from some time now. May be there soon will be a better driver. Thanks for the advice.
