    Corrupted video images usually mean "bad ram" or "bad driver".  Although I don't know if that how that would apply to an external Thunderbolt display.

     

    That might be the most solid clue you have.

     

    Be sure to check the console log.

     

    This might sound a little strange: How often do you reboot this MAC?

    I can cause my MacBook Pro Retina, 15-inch Early 2013 SSD running OS X 10.8.3 to lock up 100% of the time with the NVDA(OpenGL): Channel timeout! The problem happens using Oracle's java 7 update 21 (build 1.7.0_21-b12) whenever I launch the Java Control Panel and click on the "Settings..." button for Temporary Internet Files on the General tab. Everything locks up except for the track pad cursor / bluetooth mouse. From the Console Log the hang occurs at roughly 9:23. I let 5 minutes elapse before reseting via the power button at approximately 9:28. On this system the hang occurs 100% of the time without any intenstive graphic operations occuring. Anything I can do to resolve this?

    bpskier Level 1 Level 1 (0 points)

    I found at least a temporary workaround to my oracle 7 update 21 java control panel in temporary files settings system hang. The solution was to turn off the dynamic switching feature in OSX which switches to the nvidia GPU on heavy workloads. Apparently when oracle java starts, the system dynamically switches to use the nvidia GPU. The workaround is to keep this dynamic switch from occuring and leave the system using the built-in Intel HD Graphics 4000. http://gfx.io has a nifty tool called gfxCardStatus which can turn off dynamic switching and configure the system to use only the Intel HD Graphics 4000. It seems use of the NVIDIA GeForce GT 650M along with java hits the NVDA Channel timeout frequently at least on my system 100% of the time when in the java control panel / temporary files settings dialog.

  • 423. Re: Mountain Lion freezing
    bpskier Level 1 Level 1 (0 points)

    It seems VMWare Fusion also produces the same system hang with an "NVDA(OpenGL): Channel timeout" when the graphics mode is in dynamic switching mode and the system has switched dynamically to the nvidia GPU. Is Apple aware of the NVDA: Channel timeout problem causing system hangs on MacBook pros and might they be working on a solution?

    Hello users, I am having the same problem with NVDA Channel Timeout when using Final Cut X or firefox. The funny thing is that Apple does not fix this problem. This is very annoying. :/

    You pay for an expensive machine to have system errors or graphics drivers. If Steve Jobs were alive, I think he would have solved the problem. :/

  • 427. Re: Mountain Lion freezing
    appleidseebs Level 1 Level 1 (0 points)

    That you have machines on which it isn't happening is not exactly a persuasive argument. Obviously, the problem is somewhat sporadic.

     

    Apple seems to think it's real, because they responded to my bug report with a "we think we might have fixed this in 10.8.N, please let us know", but as it happens, I can still reproduce it.

  • 428. Re: Mountain Lion freezing
    Csound1 Level 8 Level 8 (35,455 points)

    I own and/or manage a large number of Macs, all run ML, some from new and many from an upgrade. They don't suffer from it either.

     

    Clearly it is not a widespread problem, which only makes it harder to troubleshoot, patience may be required to allow time for an identification of the cause, then a fix can be attempted.

  • 429. Re: Mountain Lion freezing
    appleidseebs Level 1 Level 1 (0 points)

    I can easily go a month without triggering it. Does that mean that for 29 days, I have a Mac which doesn't suffer from this, and then suddenly my Mac does? I don't think so.

     

    Mostly, though, I think that snide remarks like the one a few posts back about how obviously it's not a problem are (1) unhelpful (2) actually substantially anti-helpful.

     

    If you can help troubleshoot, great! If you can't, please don't pop in just to insult people and insist that there's no problem.

  • 430. Re: Mountain Lion freezing

    Show me where I said that "it's not a problem"

     

    Or

     

    Try to stick to the truth rather than your version of the truth.

     

    And do not presume to tell me where or what to post.

  • 431. Re: Mountain Lion freezing
    appleidseebs Level 1 Level 1 (0 points)

    I wasn't referring to what you said, but to what someone else said a few posts back.

     

    You can, of course, post wherever you want. But consider that Apple's discussion forums are overrun by people who do nothing but tell other people their problems don't exist, aren't problems, and don't need to be fixed, and consider how discouraging it is to people who are having a problem. You can do whatever you want, but I can post asking people to please not do things that aren't actually helping anyone. You are not obliged to act on the request; I am not your boss. And indeed, your post didn't strike me as harmful; I was just reminded of the previous post, and failed to indicate that I was drifting a little bit in topic. Sorry!

  • 432. Re: Mountain Lion freezing
    Csound1 Level 8 Level 8 (35,455 points)

    You replied specifically to me, I assumed that I was being referred to.

     

    Imagining that a problem is widespread when it is not makes fixing it harder (believe me, if it was widespread it would be fixed by now)

     

    We're cool.

  • 433. Re: Mountain Lion freezing
    bpskier Level 1 Level 1 (0 points)

    Keeping this on topic, I can reproduce the problem 100% of the time on my MacBook Pro Early 2013 model with retina display, 16 Gbyte memory, 500 GBtye solid state drive, running OSX 10.8.3, dual GPU based system (intel HD 4000 along with NVIDIA). It came installed with 10.8.3 hence I do not have data for 10.8.2 and earlier. It is entirely repeatable each and every time with exactly the same console log messages so long as dynamic GPU switching is enabled. Install Oracle Java 7 update 21 and bring up the Oracle's java control panel and select Settings for Temporary Internet Files. The GUI locks up immediately. The same is true when using VMWare fusion each and every time I bring up a windows virtual machine. Same exact messages in the console log.

     

    If I disable the NVIDIA GPU by tunring off gpu dynamic switching and leave on only the Intel HD 4000 the problem does not occur for either of the two applications. The side affect is the system can't use an external monitor via thunderbolt as this requires enabling the NVIDIA GPU and leads to the GUI hang.

     

    If you don't have a macbook pro, retina, with dual GPUs I doubt you'll experience the problem the same as I do. I have 11 other macs and one xserve. None of the others exerpience the same problem. None the others have a retina display and none of the others as far as I have looked have dual GPUs. It is also possible that the problem is just related to the NVIDIA gpu / driver and is unrelated to dynamic gpu switching. Can't say for sure as I've not done enough testing to elminiate dynamic gpu switching as the culprit for the gui hang.

     

    I've submitted my own bug report to Apple. These are my symptoms. Your mileage may vary.

    We'll see what they say.
