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? 2. the same applies if the modesetting is used - not accelerated? 3. also there is no problemos if nouveau noaccel=1 is used - not accelerated? Perhaps this is flaw within the greeter application then? -- You are receiving this mail because: You are the assignee for the bug.
