Re: [Visualpython-users] Building vpython 5.4 in Ubuntu 10.10

Just an update in case anybody having the same problem as me comes across this. I have found that visual works fine for me in Ubuntu 9.10 and earlier. I also compiled the 9.10 version of the python-visual package (available here: http://packages.ubuntu.com/source/karmic/python-visual ) in 10.10, but got the same error. So it seems that the problem is definitely not with visual itself, but may be related to the intel video drivers (my computer has an integrated intel graphics chip). I also tested this on my macbook (which has an integrated intel graphics chip as well) and got the same resutls: visual works fine in Ubuntu 9.10, but gives the "exceeded max instructions" error in 10.10. On another computer with an nvidia graphics card, visual works in 10.10 with no errors, so I'm assuming this may be a problem for computers with intel graphics cards in general. As you said, it seems like it would be hard to track down exactly what is causing the error, especially since I haven't seen any other problems with the video besides the error when trying to run visual. For now, the best solution for people with intel graphics cards is probably to just downgrade to Ubuntu 9.10 (this is fine for me since I don't specifically need any features of 10.04 or newer).
