Thanks Clotilde again.

I switched the graphics card driver and it has fixed the problem.
The switch I made was from Nouveau display driver to Nvidia dreiver.

Thanks,
Abhinav

Hello,
probably a driver/graphic card problem. Maybe trying the legacy driver for your card could help.

    Hi,

    I installed pymol ( pymol-v1.7.0.5-Linux-x86_64.tar.bz2) on my
    ubuntu (12.04 LTS) desktop and this was working fine.
    Later, I upgraded my Ubuntu to 14.04 LTS and now pymol has become
    extremely sluggish. Even rotating a small molecule like ATP takes
    a while.

    Any suggestions on how to fix this?

    Coot and rasmol are not affected by this Ubuntu upgrade.

    Thanks,
    Abhinav

    Greetings,

    We'd like to announce the release of Incentive PyMOL 1.7.0.5, which is a 
bugfix release. Applicable bugfixes have also been pushed to the sourceforge 
SVN repository as Open-Source PyMOL 1.7.1.3 (SVN rev 4076).

    Fixed bugs include:

    Incentive PyMOL (for licensed users):
      - don't disable all shaders if geometry shaders are not available
      - many z-depth issues for labels and connectors in immediate, shader, and
        ray tracing (all renderings should now look almost exactly the same)
      - background in front of text with use_shaders=0
      - label picking broken with use_shaders=0
      - character rendering in ray tracing
      - clipped text in multi-line labels (shader on and off)

    Open Source and Incentive PyMOL:
      - cartoon memory leak
      - CGO colors ignored with ALPHA
      - hidden groups flash in scene based movies
      - "A > find > polar contact > just intra-side chain" broken
      - "scene auto, update" broken
      - small solvent_radius crashes Surface generation
      - grid_mode support for volumes

    Some of these changes have been in the SVN repository for a couple of weeks.
