I mentioned this problem about a month ago on the Pd list but it was cluttered with a bunch of other issues and may not have been explained well.<br><br>I have seen 3 different machines completely lock up between 10 seconds and forever when a Gem window is open. All that is required is that the Gem window is open. Redsquare, for example, will trigger the symptom if the gem window on that patch is opened. The lock up doesn't happen immediately but happens sporadically. It also happens continually. During the lockup, even the mouse won't move and the screen is not updated. After the lockup, suddenly the machine will be OK --- until it locks up again a few minutes later.<br>
<br>Other opengl apps don't lock up. For example, I can run glxgears all day with no problems.<br><br>The machines all had the following in common:<br>- ubuntu Intrepid (1 had 64 bit one had 32 bit)<br>- nVidia proprietary driver that comes with Intrepid (I tried 3 different versions of the driver. Same symptoms)<br>
- AMD branded processor<br>- Gnome/metacity or Gnome/compiz<br><br>One of the machines had 64 bit Hardy and ran fine. Then when changed to 32 bit Intrepid the symptoms came up.<br><br>One is a laptop, the other two are desktops.<br>
<br>Does anybody else have Intrepid/nVidia/Gnome? It would be interesting to see if he/she is also having the same problem.<br><br>
