[Mesa3d-dev] [Bug 10488] New: assertion failure in libGL.so.1 when running wine on xvnc4 at 16bpp
http://bugs.freedesktop.org/show_bug.cgi?id=10488
Summary: assertion failure in libGL.so.1 when running wine on
xvnc4 at 16bpp
Product: Mesa
Version: unspecified
Platform: Other
OS/Version: All
Status: NEW
Severity: normal
Priority: medium
Component: GLX
AssignedTo: mesa3d-dev@lists.sourceforge.net
ReportedBy: [EMAIL PROTECTED]
When running any program under wine (e.g. winecfg) on xvnc4server,
assertion fails inside libGL.so.1 from libgl1-mesa-glx package:
glxcmds.c:343: CreateContext: Assertion `mode != ((void *)0)' failed.
A quick look info code shows that it hits a 'FIXME':
...
337 if ( fbconfig == NULL ) {
338 /* FIXME: Is it possible for the __GLcontextModes
structure
339 * FIXME: to not be found?
340 */
341 mode = _gl_context_modes_find_visual( psc->configs,
342vis->visualid );
343 assert( mode != NULL );
344 assert( mode->screen == screen );
345 }
...
This bug originally was reported to Debian BTS,
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=415292
The bug log there contains some backtraces.

[Mesa3d-dev] [Bug 6355] Building GLcore in mesa (suggestion)
http://bugs.freedesktop.org/show_bug.cgi?id=6355 --- Comment #13 from [EMAIL PROTECTED] 2007-03-31 03:26 PST --- Hi Kristian, thanks for reviewing. I should probably mention that out of the issues mentioned in your original mail: - glapi is a non-issue with the patches because the xserver still symlinks those from mesa, I think this should be handled separately - GLcore i/f versioning still needs to be looked someway -- Configure bugmail: http://bugs.freedesktop.org/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are the assignee for the bug, or are watching the assignee. - Take Surveys.

Miniglx currently in theory works hw-accelerated on radeon and intel i9xx hardware using the Linux kernel fb-drivers to do modesetting, and the drm to do the 3D acceleration, when the intel modesetting code is in the drm tree I'll make a miniglx to use that as opposed to fbdev just for a proof of concept and for perhaps an upcoming deployment into a production system..

[Mesa3d-dev] Mesa - Scitech? myOS - Miniature, Linux based OpenGL development system without X
hi, brian suggested this was the best place to post this info and my questions, so here i go: *** project myOS - Miniature, Linux based OpenGL development system without X It is bare bones Linux system, stripped down of everything, but core necessary files to compile and run OpenGL/C code. It has simplified directory structure and cleaned up internal cross referencing. There is complete OpenGL Red Book together with 45 examples converted to use Scitech's drivers. Examples are organized to follow chapters and are ready to compile and run, they look very much like their GLUT version in Red Book. This little collection is really all one needs to learn OpenGL. In fact the whole system being very bare bones and really simple can be used as learning tool to teach Linux basics and C/OpenGL programming... http://one.xthost.info/zelko/opengl.html there are more OpenGL related downloads on that page including old demos that were developed for Voodoo2 using Mesa *** questions 1.) can you please tell me, since Scitech drivers are based on Mesa, why there is no mention of them on Mesa web site? 2.) can you help me figure out, how come no one uses Scitech to do "Linux without X" even tho they are clean, working solution? and, i mean there is not a single Linux project using them, until now.. 3.) i could not figure out 'Mesa minixgl', dont even know what exactly and where is the source code for it, i tried GGI, directFB and looked into other "without X" projects, but they so much trouble to compile, have dependencies that i want to get rid of, hard to isolate, clean or are simply too big. since all the 'Linux without X' drivers are based on Mesa anyway, i assume minixgl might be most simplistic and smallest, therefore best solution for me, so: is minixgl active? can someone point out if there is nice simple link that will download all necessary source of minixgl in ONE file? 4.) im looking forward to Mesa fbdev/DRI project or similar to have wider supported hardware, but meanwhile can you suggest if you know of any other Linux drivers that might be used to create "Linux-OpenGL without X" system? cheers, zelko - Take Surveys.
