Hello:
I'm using CEGUI from a while ago and everythings rocks!..
Now I have an Elografics machine with a ProSavage DDR video card and I have some problem with the render opengl. Every sample i tried it I get black screen with no errors, I checked the log. I have DRI, DBE and opengl installed and working fine. I run some others opengl sample and some times I get the same error and in others everything run fine. I tried with the latest version of CEGUI from the svn and I see the screen but I get 3 fps max. Can you give me some tips to find the problem?
I'm using archlinux and I test it with glxgears and the render was Mesa DRI with 4 apgx.
Could be drivers problems?, I'm using savage driver.
Thank you..

Hi,
Is it 0.6.2 that gives you the black screen? Just trying to establish which versions do what - especially since the svn code is so radically different
It could be a driver issue, the mention of Mesa seems to indicate that perhaps you're running the Mesa software renderer?
What kind of output do you get from glxinfo? Pay particular attention to the various vendor strings and the "direct rendering" line, where a no would normally indicate an unaccelerated GL implementation of some kind.

Hi,
Yes it should work in theory; especially in 0.6.2 code the renderer is using only the very basic functions. While the speed issues experienced definitely sound like an issue with hardware acceleration, the 'black screen' in the samples for 0.6.2 should never really be seen.
While I do not have access to a machine with that particular video card, I will run a test later under Mesa just to be sure we've not introduced an issue somewhere.

Hello:
My output of glxgears it's:
GL_RENDERER = Mesa DRI Twister 20061110 AGP 4x x86/MMX/SSE
GL_VERSION = 1.2 Mesa 7.2
GL_VENDOR = S3 Grapics Inc
I have the AGPSize: 128MB.
I have another 2 machine using Mesa DRI with openchrome and Intel driver and work fine.
Can I do use another of mesa render?
Salu2..

Can you post the output of glxinfo instead, I want to see what extensions are reported. There was a bug in 0.6.2 related to detection of GL extensions, basically you will only see the issue if ARB_multitexture is not reported and the GL version is lower than 1.3; I think this is the likely culprit. (The issue is fixed in both svn trunk and branches/v0-6).

This tells me the issue is definitely somehow related to the driver / video card in use. As such, I think you're seeing the issue from above.

Not really, no (I'm no expert on such matters!). I would have thought that so long as X was up and running, the fact that you have a window manager running on top of it (or not) should make no difference; unless it's some oddity related to glut that needs this (I really don't know, though).
