https://bugs.freedesktop.org/show_bug.cgi?id=89730 --- Comment #11 from poma pomidorabelis...@gmail.com --- This also works but it looks like another variations on a theme - not accelerated. Section Device Identifier video0 Driver nouveau Option ShadowFB on EndSection Option ShadowFB boolean Enable or disable use of the shadow framebuffer layer. Default: off. If this option is enabled, the driver will cause the CPU to do each drawing operation first into a shadow frame buffer in system virtual memory and then copy the result into video memory. If this option is not active, the CPU will draw directly into video memory. Enabling this option is beneficial for those systems where reading from video memory is, on average, slower than the corresponding read/modify/write operation in system virtual memory. This is normally the case for PCI or AGP adapters, and, so, this option is enabled by default unless acceleration is enabled.

If you're comfortable modifying code, you could start hacking away at xf86-video-nouveau. Take a look at src/nv50_exa.c -- there are a bunch of functions like NV50EXAPrepare*. In each of them, Just put as the first line (after variable decls) something like NOUVEAU_FALLBACK(poma\n); If you do it in all the prepare functions, I bet that the background will start to work. (And you will basically have no accel.). Figure out which operation is the one that causes all the trouble (by starting to remove the fallbacks). Once you figure out which high-level op it is, I can provide further instructions to narrow down the specific operation further. -- You are receiving this mail because: You are the assignee for the bug. ___ Nouveau mailing list Nouveau@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/nouveau

https://bugs.freedesktop.org/show_bug.cgi?id=89730 --- Comment #9 from poma pomidorabelis...@gmail.com --- (In reply to andrew p. from comment #7) Some clarifications: - Greeter is usual GTK3 application. - No WM or compositor run in greeter session. - Greeter creates one GtkWindow for each monitor. - Greeter uses standard cairo functions to draw monitor's window background. There are no login or panel windows - just child widgets inside fullscreen window. This grey color looks like default window color - just set background=#default to see it. So, the question - why gtk draw semi-transparent panel correctly (using parent window background as base) and do not do it for free space. Add allow-debugging=true option to lightdm-gtk-greeter.conf to get more informative log. Some questions: 1. What happened if background is color (#0f0)? I don't expect that there will be any difference, just interesting. 2. Another gtk theme? Or empty theme-name=. Color codes work OK, theme also does not affect the final outcome. background color (#0f0) - green, works OK as any other. I saw very similar bug some time ago - laptop with archlinux and catalyst. In some cases gtk didn't draw whole windows except some widgets (text entries - blinking cursor). But this bug is gone now.

There's a weird bug where if you do some crazy things you can get stale window contents... this doesn't feel like that one though. Could be a compositing or who knows what issue. In a *perfect* world, there would be a simple stand-alone app that reproduces this, and we can use that to debug.

[Nouveau] [Bug 89730] NV50: LightDM GTK+ Greeter Background - inconsistent display
https://bugs.freedesktop.org/show_bug.cgi?id=89730 --- Comment #3 from poma pomidorabelis...@gmail.com --- (In reply to Ilia Mirkin from comment #1) I may be slow... but I don't fully comprehend what the problem is. Note that I'm not familiar with lightdm beyond it being an xdm replacement. Is it using X or GL to do the displaying? I note that CSS is being used -- do you know what processes this? Perhaps you can get a lightdm person to help with debugging? I left a note on the ligh...@lists.freedesktop.org, so devs can comment here. LightDM is the display manager - it starts the X server and greeter (login screen) - in this case LightDM GTK+ Greeter. -- You are receiving this mail because: You are the assignee for the bug. ___ Nouveau mailing list Nouveau@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/nouveau
[Nouveau] [Bug 89730] NV50: LightDM GTK+ Greeter Background - inconsistent display
https://bugs.freedesktop.org/show_bug.cgi?id=89730 --- 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. ___ Nouveau mailing list Nouveau@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/nouveau
