  • Ticket #314 – Description

    initial v1  
    33* {{{GL_VERSION}}} at least 1.1
    44* checks the driver properties against our blacklist: we simply refuse to work with the "nouveau" Linux driver (too buggy) and "Humper" (the driver in {{{VirtualBox}}} - also buggy, but worse!)
    5 * then some other irrelevant checks.. (required extensions, etc - does not get that far)

    1414The (unavoidable?) problem with this approach is that if and when {{{VirtualBox}}} fix the driver issue, we will still end up ignoring it and {{{OpenGL}}} will remain disabled.. Unless we can somehow load the driver version from the DLL and detect the versions that do work?

     16Interestingly, running the {{{OpenGL_test.exe}}} command, which is installed as part of xpra and runs the exact same code, does not seem to be able to crash the VM - though I did get this error instead (you have to run it many many times to hit errors):
     17* this in stdout:
     18{{{
     19OpenGL Warning: SHCRGL_GUEST_FN_WRITE_READ (28) failed with ffffffdb ffffffea
     20}}}
     21* and an alert:
     22{{{
     23The instruction at "0x05451a1f" referenced memory at "0x00000008". The memory could not be "read".
     24}}}
     25Looks like a bad pointer somewhere. Note: I reproduced the exact same values above twice..
