garf Posted September 19, 2016 Share Posted September 19, 2016 Hey all, I've recently installed Linux Mint 18 on to a dual boot on my laptop. I've been running houdini on windows 7 for a while without any problems. On Linux, however, I'm finding that Houdini will crash immediately I wake the laptop from sleeping (i.e. lift the lid up). Any ideas? Houdini 15.5 Apprecntice Thanks Quote Link to comment Share on other sites More sharing options...
malexander Posted September 20, 2016 Share Posted September 20, 2016 On Linux, the Nvidia driver has no way of notifying the application that a suspend/resume cycle has nuked various GL objects. We attempt to do a test for this in Houdini when a redraw hasn't occurred in a while, and while the test did seem to work for some earlier driver versions and Linux distributions, it's not a sure thing. Nvidia has recognized this issue and added a GL_NV_robustness_video_memory_purge extension, but I've yet to see that pop up in a driver. Once it does I will see if it can be integrated into Houdini.

lukeiamyourfather Posted September 20, 2016 Share Posted September 20, 2016 This happens on Windows 10 as well. The overwhelming majority of times I've woken the machine up from sleep Houdini crashes. I sent an email to support a year ago or so and the answer was basically deal with it.
