Full screen fails on Linux with Dual Monitors
Archives Forums/BlitzMax Bug Reports/Full screen fails on Linux with Dual Monitors
| ||
I've experienced this myself, but now two other customers have reported the same error: the game runs fine in a window, but if you try to run it full-screen with two monitors it crashes with this output:X Error of failed request: BadMatch (invalid parameter attributes) Major opcode of failed request: 144 (GLX) Minor opcode of failed request: 5 (X_GLXMakeCurrent) Serial number of failed request: 133 Current serial number in output stream: 133 Locking assertion failure. Backtrace: #0 /usr/lib/libxcb-xlib.so.0 [0xd8d767] #1 /usr/lib/libxcb-xlib.so.0(xcb_xlib_lock+0x2e) [0xd8d90e] #2 /usr/lib/libX11.so.6 [0x5d7c109] #3 /usr/lib/libGL.so.1 [0x637f792] #4 [0xd7fbf98] |

| Wanted to add that I have seen this using Ubuntu 7.10 and 8.04, and one of my customers is reporting it on Fedora 9. |

| I adapted some code (to show my friends) from code adapted from someone who read ImaginaryHuman's "metaballs" post. I am getting a similar error (see below), and am going to try "reinstalling" (am on Debian Lenny with XFCE4) all OpenGL-related libraries, as well as the libraries above, and see if this doesn't fix what's wrong. Also, while using hardinfo, I got a similiar error message sent to the command line ("glXCreateContext failed" when I went to the "Display" section). Edit: The "metaballs" code did not cause the problem, but it is the only program I have so far that I know uses OpenGL. Only graphics are affected, actually. Could someone please move this entire thread to the Linux forums? I have a funny feeling that this is NOT a Blitzmax bug (because Blitzmax has been working fine so far, and because there are glx-type-errors in my Xorg file from as far back as last month). Here is the message I got from the BlitzMax output: Building AlphaBlendingPowerOf_BlitzMax Compiling:AlphaBlendingPowerOf_BlitzMax.bmx flat assembler version 1.67.36 (32768 kilobytes memory) 3 passes, 14906 bytes. Linking:AlphaBlendingPowerOf_BlitzMax.debug Executing:AlphaBlendingPowerOf_BlitzMax.debug X Error of failed request: BadMatch (invalid parameter attributes) Major opcode of failed request: 143 (GLX) Minor opcode of failed request: 5 (X_GLXMakeCurrent) Serial number of failed request: 35 Current serial number in output stream: 35 Process terminated These were the parameters given to /bin/bmk, by the IDE: -x -d -t gui -a -o I am going to try to solve this myself, but I doubt I will be able to. I am not finished yet, though. I will post more the farther I get. On a related note, after reading this post, I am less hopeful that it is a driver/library issue. :/ |

| Ha ha! I fixed it (but I still don't know what the cause was). I uninstalled and then reinstalled the NVIDIA drivers for my graphics card and everything is fine (for now). I was looking and looking for something (since I know little more than the layman does about OpenGL), some clue to the issue, and then I just thought "to hell with that". I was actually gonna reinstall the whole operating system, but decided to try reinstalling the driver first. I still have lots of log files if anyone is bored and wants to read through them (if you want to I will be very forthcoming with all of it (but for people reading this a month afterward, they will be gone, so tell me now or forget it)). And this may or may not say something about how Blitzmax is coded, I don't know: http://www.opengl.org/discussion_boards/ubbthreads.php?ubb=showflat&Number=200168 And maybe this, who knows, but here they are: http://www.opengl.org/discussion_boards/ubbthreads.php?ubb=showflat&Number=253074 http://www.opengl.org/discussion_boards/ubbthreads.php?ubb=showflat&Number=255685 The three links are for those who have time to kill, otherwise this can fade away (into the archives!). Edit: I'm vaguely sure it has something to do with using gdm (Gnome Display Manager, and see here for why), though, because I was a little tired of xdm not letting me shut down the computer from the (graphical) login screen. ...When I discovered my motherboard supported acpi power-off calls (I can press the power button and send a call to the operating system to shut down (safely)). So now all is good. |
