I seem to be having a problem when I boot up my computer. I use Kubuntu 13.04 but I thought I would try XFCE since my computer has had graphics issues in the past (which is actually the reason I use Kubuntu). But now when I boot up my computer it just endlessly pulses blue around the Kubuntu logo. I got the Xorg.0.log log and this is what the last few lines say:I have a Compaq Presario 5430US with 1GB of RAMCode:[ 33.393] (EE) NOUVEAU(0): [drm] failed to set drm interface version.[ 33.394] (EE) NOUVEAU(0): [drm] error opening the drm [ 33.394] (EE) NOUVEAU(0): 820: [ 33.394] (II) UnloadModule: "nouveau" [ 33.394] (EE) Screen(s) found, but none have a usable configuration.
