    Natty fresh install snow artifacts, X hogs cpu

    A few days ago I did a wipe and fresh install of 11.04 on my desktop machine, and am experience video issues. I've got a GeForce 210 video card, dual monitors, running the NVidia proprietary drivers.

    The first issue is that the X server frequent hogs the CPU. HiTop frequently reports it in excess of 70%. And I've noticed that occasionally X will launch of VT8 instead of VT7 (currently, for example, vt7 shows "mountall: Disconnected from Plymouth", so is this an issue with Plymouth integration?).

    UPDATE: kdeinit is another frequent CPU hog. Currently, HiTop is reporting two instances of "kdeinit4: kded4 [kdeinit]" at 101% and 98% with "/usr/bin/x :0 vt8 -nr -nolisten tcp -auth /var/run/xauth/A:0-HVk6oc" between 6 and 60%.

    UPDATE 2: the kdeinit problem seems to be the same as this thread, which references this bug report. Fortunately, kill -9 kills it without apparent side effect.

    The second is severe snow artifacts, with near-zero visibility when I drag windows around. This happens with or without desktop effects enabled.

    Am I alone?

      Thanks for the reply. I've had a look at the link you provided, but I don't think it's applicable in this case as I've got a fresh Natty install, and I specified for it to install the proprietary drivers automatically at install time. I would guess I've got the Ubuntu-supplied drivers (but how would I check?).

      NVIDIA X Server Settings shows the following:

      NVIDIA Driver version: 270.41.06

      X Server:
      Server Version 11.0
      Server Vendor String The X.Org Foundation
      Server Vendor Version 1.10.1 (11001000)
      NV-CONTROL Version 1.26

        BUMP

        Anyone? This is a fresh Natty install, all wallpapers are disabled, no widgets. Even at idle, CPU usage regularly climbs to over 50%. The two culprits, according to htop, are X and plasma-desktop, both consistently in the low-to-mid double digits with spikes up to 78% or more.

          BUMP.

          Haven't seen the snow in a couple of days, but CPU usage continues to run high. Anyone?
