Re: [PD] Can't create gem window on a beagleboard
Well, I'm not aware of such details, to be honest. Since Gem is installed the Pd version my beagleboard has, I tried to do something with it. The objects are being created, but no gem window..

Re: [PD] Can't create Gem window
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.

Re: [PD] Can't create Gem window
After adding
export LIBGL_ALWAYS_INDIRECT=1
to $home/.bashrc
glxgears works fine, but not Gem. Still the same. ?!
glxinfo gives me a lot of output, and the table seems to indicate better-than
the values you gave below, e.g.
Vis Vis Visual Trans buff lev render DB ste r g b a aux dep ste
accum buffers MS MS
ID Depth Type parent size el type reo sz sz sz sz buf th ncl r
g b a num bufs
0x23 0 TrueColor 0 32 0 rgba 1 0 8 8 8 8 0 24 8 16
16 16 16 0 0
I can't find GLX_DOUBLEBUFFER
Could it be that I need to add some lines to xorg.conf (wherever it is in Lucid
Ubuntu)
