Hi all,
There are previous posts on this topic, but the advice they give doesn't seem to apply to this particular flavor of the error message (at any rate, I didn't have any luck with them). I'm attempting to run the VNL 12.8.2 trial on Ubuntu 12.10. The system is a 64-bit Dell Latitude E6510 with Intel HD 3000 graphics. VNL loads with no trouble and launches the builder, but whenever I try to take any action in the builder (such as adding a new configuration), the whole program crashes, leaving the following crash_log:
X Error: GLXBadContext 172
Extension: 154 (Uknown extension)
Minor opcode: 6 (Unknown request)
Resource id: 0x42010f6
[xcb] Unknown sequence number while processing queue
[xcb] Most likely this is a multi-threaded client and XInitThreads has not been called
[xcb] Aborting, sorry about that.
vnl_exec: ../../src/xcb_io.c:273: poll_for_event: Assertion `!xcb_xlib_threads_sequence_lost' failed.
My libGL.so is from mesa, which I know is a generic openGL driver, but given the Intel HD graphics, I'm not sure I have any other choice. VNL --> About does show the source of my video driver to be "Intel Open Source Technology Center". Has anyone had a similar issue, or could anyone help me out with this? I'm totally stuck, and the Builder is unfortunately the primary functionality of interest.
