--- Comment #5 from Ilia Mirkin <imir...@alum.mit.edu> --- (In reply to poma from comment #4) > dunno whether it is proper position, but comparing with the > NV50_3D(ZETA_ENABLE) in src/nvc0_accel.c > your patch fit like this: Yes, this is what I had in mind. On my local branch I've replaced a bunch of the 0xbla values with names :) Thanks for testing, it was a long shot though. > Nevertheless it still has no effect. > > With regard to your question - GL, I tried the following: > options nouveau noaccel=1 > > and it has a positive effect - Greeter Background is displayed correctly. > > After all this, if I understand it correctly: > 1. Family : NV30 / Chipset: NV34 (NV34) / GeForce FX 5200 > because it has no problemos in this case - per se is not accelerated? Nope, it's accelerated. Just all the acceleration logic is different, it's very different hardware. > 2. the same applies if the modesetting is used - not accelerated? Right. Or perhaps it's using glamor to implement EXA? Depends on the modesetting version. > 3. also there is no problemos if nouveau noaccel=1 is used - not accelerated? Right, not accelerated. You can be more targeted and set Option "AccelMethod" "none" in your xorg.conf which will only disable 2d accel via the ddx. Or you can try setting it to "glamor" and see if the problem goes away. > > Perhaps this is flaw within the greeter application then? Perhaps. Would be nice to know wtf the application is doing in the first place, then we may be able to work out where the issue might lie. At this point I don't know if it's using X or GL for drawing this stuff to the screen, which are very different paths. -- You are receiving this mail because: You are the assignee for the bug.
