Prezados Senhores,
Uma coisa bem desagradável aconteceu com o meu Kubuntu, depois de uma atualização para o kernel 2.6.15-25-k7 não consigo mais logar como usuário na tela gráfica do Kubuntu ( consigo no console ), e mesmo quando logo no console o X não entra, só entrando como root ( logando no console primeiro e subindo o x manualmente ). Isto passou a acontecer logo depois de dar o boot pelo kernel atualizado.
Tentei rodar pela versão mais antiga do kernel e não tive resultado, já fiz uma segunda atualização de kernel ( agora para 2.6.15-26-k7 ) e continuou na mesma.
Abaixo vai um trecho do log do Xorg:

A minha placa de vídeo atual é uma ATI 9800 Pro.
Parece que depois da atualização do kernel a aceleração 3D que antes estava funcionando perfeito ( testei inclusive com alguns jogos ) foi para o brejo ( ô driver ruim este da ATI, ainda bem que em breve trocarei por uma nVidia ).
Toda ajuda será muito bem vinda.
