    <p>It turns out the problem was that the open source Nvidia graphics
      driver, nouveau, was being used.  The fix is to use the Nvidia
      proprietary/OEM graphics driver.  See

        <p>Hi</p>
        <p><br>
        </p>
        <p>I had to change my hard drive and reinstall everything. When
          launching chimerax, it starts but freeze. Have to kill it. OS
          ubuntu 22.04. No special message in the log when using
          chimerax --debug</p>
        <p>Any idea ?</p>
        <p><br>

        <p>Thank's</p>
