Well after fighting with xvidcap, animate, convert, mplayer, mencoder and finally ffmpeg, I finally managed to get a video made! Woo!

Quality is poor, it didn't capture completely smoothly, and I think I rushed through the action, but I'm gonna have a break before I attempt to make any more.

http://rapidshare.de/files/11356766/xgl_zoom_rotate.avi.html (800x600 mpeg4 2Mb)

My desktop is usually 1920x1200, but I made the Xgl window 800x600 so it would be a reasonable size - That's why my fonts look so big. It's much harder running Xgl from an already running X server than it is to just run it from the command line.

I didn't realise there was such a long wait on rapidshare... So I'll be nice a little longer:

EDIT: REMOVED VIDEOS

(Oh, and I borrowed irondog's video

)

Thanks, got it compiled that way too. Doesn't change the fact that E17 works very slowly and resizing windows is slow. Also xv is slow. glxcompmgr effects work fast and look super though

Is there any way to get DRI working under Xgl?

I think you need ati r200 or below for good dri support. And thanks for solution to my problem irondog. It worked like a charm! Now installing gnome-light for xgl testing

.xinitrc is for the normal X server, and has nothing to do with Xgl.

I have 2 scripts, one to start from the command line after I log in, and one to run from an existing X server:

Can you run any X programs? eg. xterm?

Maybe there's something in people's setups that are causing such a difference in stability? I'm on ~amd64, 2.6.15-archck1, gcc4.0.2, nxsty's glibc-2.3.90.20051211, xorg 7, kde 3.5, nvidia (6800nu) and I everything compiled from scratch (toolchain first) when I changed over to gcc4 and the tweaked glibc, with -Bdirect and nptl(only).

32 vs 64 bit and gcc versions seem to be the main differences between our setups. Does anyone else have KDE / qt stable, or am I just lucky?

boniek · Guru Joined: 26 Mar 2005 Posts: 373

Some glitches (like improper shadow rendering) and slow (and I mean really slow) widget rendering. Thats with kde 3.5 and Xgl. Fast, without glitches. Thats Gnome 2.10 and Xgl

. Ati proprietary driver 8.20 and r300 chipset (radeon 9500), 32bit athlon-xp system, gcc 3.4.4.
I can't seem to get Xgl to work when starting from bash (without any X server running) though. It just hangs. Zapping serwer and running ps aux shows it as <defunct> process. Any ideas?

I'm having trouble emergeing the xgl build mentioned above.

To start with, I had to comment out all the patches, as they all fail. Maybe this was the start of my problems.

Anyway, while building, I get:

I could use some help getting my Xgl build going, but first some questions: What exactly is kdrive and how is it different from the regular X server? How much of the code is shared between the two?

Ok, so onto my problems... First, I had compiling problems with the xserver from cvs. I'm using an ebuild I grabbed from here which I've had to modify slightly to make it work right on my amd64. I've got mesa, glitz, cairo, xgl, glxcompmgr all from cvs. I had to comment out some of the patches those ebuilds used (one-liners) b/c they didn't apply cleanly but that doesn't seem to have affected the making of any of them. The first compile error I got was this:

I've deleted my overlay directory and started again. Without commenting out any of the patches, my build fails at:

Anyone have an idea how to get round the bug with the new portage release with hanno's ebuid overlay ??

irondog · Posted: Fri Jan 20, 2006 4:30 pm Post subject:

I'm using portage-2.0.53. No big problems here. But I used and posted a work-around here to get it all working. I've no idea whether this work-around has anything to do with the portage bug concerned or not.

Alright, I finally got mine up and running. It's like 3AM and I don't even wanna go to bed now. My first impression is that the graphical response to the user is much better with the sweeter eyecandy (than say, windows or regular X). I LOVE the way windows move, menus appear, alt-tab highlights the currently selected window (with transparancy!), windows make cool intros and exits when minimized and restored, etc. This is really amazing.

I do notice that my CPU use goes up to about 50% when doing something cool-looking, but I can live with that. Is that something that could be subject to later optimization or is it not really something that can be fixed? I also notice that sometimes moving stuff on the screen will make a sort of skip in the redraw, kinda like it missed a frame in drawing. Other than that the rendering is pretty good. I don't have any artifacts on the screen yet.

Now for some problems I've already noticed. These are mostly with the X server itself and I'm sure they'll all get fixed eventually.
1. nVidia's twinview is broken. I've got no xinerama stuff going on with this thing. I can live with that for now.
2. My xmodmap seems to be broken. It thinks I only have 7 buttons now, x11r7 thought I had 13. I actually have 9 and my config says so :-)

3. gnome panels don't get their always-on-top way with glxcompmgr running (or ever started, it doesn't come back). This problem happened with xcompmgr as well and is a known bug I think.
4. I just maximized a window, unmaximized, now every time I try to move it it gets HUGE, then returns to normal when I let it go. Other windows aren't doing this, though it is reproducable with any window.
5. resizing windows is a bit awkward with the wobbly motion making it move as I resize it. That might be better left off or done in some other way.

Wait - there's more! I just checked glxinfo, which says I'm not using direct rendering. If this looks this good with software rendering, 1) that explans my CPU usage, and 2) how amazing will this be when I figure out what's wrong? This is the only error I get in my Xorg.0.log:
