do glxgears work?
yes.
if so, what is your pixel-depth? Gem wants to create a 24bit buffer, so if you are running your X in 8bit/palette mode it will bail out.
xorg.conf says 24, using proprietary ATI driver for the HD7700
DefaultDepth 24
this is what Gem requests: { GLX_RED_SIZE>=4, GLX_GREEN_SIZE>=4, GLX_BLUE_SIZE>=4,
GLX_DEPTH_SIZE>=16,
GLX_STENCIL_SIZE>=8,
GLX_ACCUM_RED_SIZE>=8, GLX_ACCUM_GREEN_SIZE>=8, GLX_ACCUM_BLUE_SIZE>=8,
GLX_DOUBLEBUFFER }
verbose output of glxinfo indicates doubleBuffer =1 rgba are all =8 depth =24 stencil =8 accum are all =16 doubleBuffer =1
system spec: Intel Core i5 Radeon HD7700 graphics card. Ubuntu 10.04
I am wondering if the ati proprietary driver might be to blame, but I am not sure how to check this... Ed
looks good: Visual ID: 6b depth=0 class=DirectColor
bufferSize=32 level=0 renderType=rgba doubleBuffer=1 stereo=0 rgba: redSize=8 greenSize=8 blueSize=8 alphaSize=8 auxBuffers=0 depthSize=24 stencilSize=8 accum: redSize=16 greenSize=16 blueSize=16 alphaSize=16 multiSample=0 multiSampleBuffers=0 visualCaveat=None Opaque.
check the output of glxinfo, whether your config supports such a setting.
