Hello List, I've recently upgraded to X4 and I'm having problems with DRI. I'm using a Matrox G400 and a 2.4.0-test5(from the woody .deb) kernel.
With the mesag3 package from woody installed, glxinfo shows direct rendering is enabled but if I run some of the GL xscreensavers i.e. superquadrics and lament, they appear to be using s/w rendering. This is in comparison to the old 3.3.6 + utah_glx combination which was much faster and appeared to give higher quality too. If I replace mesag3 with xlibmesa3, glxinfo shows that direct rendering is not enabled but the screensavers run the same as with mesag3. In /var/log/XFree86.0.log I found the line:- (EE) MGA(0): [drm] MGADRIScreenInit failed (DRM version = 1.0.0, expected 2.0.x). Disabling DRI. which looks like it might be the cause of the problem but if so, what do I do about it? TIA LeeE
