| ricotz | mlankhorst, hi :), are there (precise) packages for wine 1.6.1 yet? | 12:03 |
|---|---|---|
| mlankhorst | ricotz: erm scott ritchie does those | 16:37 |
| ricotz | mlankhorst, ok, thanks, since you are involved too, i was hoping you had uploaded it somewhere already -- haven't found it on launchpad though | 16:45 |
| ali1234 | i've got a question about RetainPermanent and the various atoms used to signal the existence of such on the root window pixmap | 20:31 |
| ali1234 | first: there's a bunch of different ones: XSETROOT, XROOTPMAP, ESETROOT_PIXMAP_ID, _XROOTPMAP_ID... any more? | 20:33 |
| ali1234 | second: how do these pixmaps get freed? if i set and change the background image using one of these tools, it's going to keep allocating new RetainPermanent pixmaps. how are they supposed to get deallocated? | 20:34 |
| ali1234 | RAOF: in my searching on this topic i saw you discussing RetainPermanent in relation to unity-greeter. can you tell me anything about this stuff? i'm hacking on lightdm-gtk-greeter for xubuntu | 20:36 |
| ali1234 | it looks like unity-greeter defines RetainPermanent but doesn't use it. so how does the wallpaper handoff happen between unity-greeter -> compiz? | 21:01 |
| mlankhorst | ali1234: no idea, magic? :> | 21:02 |
| ali1234 | well all this RetainPermanent stuff sure feels like magic | 21:02 |
| mlankhorst | I guess until compiz starts compositing the old image will exist | 21:03 |
| mlankhorst | because nothing new has been drawn to it yet | 21:03 |
| ali1234 | the problem we have is xfwm starts compositing with a empty grey buffer, and there's a delay before the app that draws the wallpaper starts up | 21:04 |
| ali1234 | xfwm can read the RetainPermanent background at startup to avoid this, but the whole thing seems incredibly bad with magic atoms and unmanaged buffers... | 21:04 |
| mlankhorst | I think you can just read out the uncomposited buffer before starting to composite | 21:17 |
| mlankhorst | or at least delay drawing until you have a background | 21:17 |
| mlankhorst | but I haven't put much thought since I mstly worry about driver issues ;) | 21:18 |
| ali1234 | speaking of driver issues, why does nouveau corrupt the hell out of the display when using RetainPermanent pixmaps? | 21:19 |
| ali1234 | "oh, you wanted your wallpaper? here's some windows that were on your screen earlier today" | 21:20 |
| ali1234 | i think "read out the uncomposited buffer" is what compiz does, that's probably going to be our best option | 21:22 |
| mlankhorst | I guess it uses random vram memory with nothing drawn to it yet | 21:22 |
| mlankhorst | which happens to match window contents in some cases | 21:22 |
