Hi All, I'm trying to run Mavis Beacon Teaches Typing 20 on my Ubuntu 9.10 64 bit with wine 1.1.37, but it is extremely laggy. The mouse stutters ever 2 seconds or so, making it difficult to click on anything. Running it from command line, I noticed this error message: Code: err:winediag:X11DRV_WineGL_InitOpenglInfo Direct rendering is disabled, most likely your OpenGL drivers haven't been installed correctly I am using the ATI open source driver, and from what I can tell DRI is working. glxinfo says: Code: display: :0 screen: 0 direct rendering: Yes server glx vendor string: SGI server glx version string: 1.2 I've searched the error using the search function, but the search doesn't seem to bring back anything relevant. Using google found this forum thread, http://forum.winehq.org/viewtopic.php?t=7370&sid=446054b5899e48d75f706a500416ccfd The solution appears to be installing the 32bit DRI drivers, which I believe are ia32-libs. The version installed on my system is 2.7ubuntu17. I found this bug: https://bugs.launchpad.net/ubuntu/+source/wine1.2/+bug/506320 Which appears to be specific to nvidia (and doesn't fix my problem). I also tried LD_PRELOAD=/usr/lib32/libGL.so wine Mavis.exe, and that made it even slower. Anyone else run into something similar? Any thoughts appreciated.
