if you're testing Rockhopper!, please do us a great big favor and give us feedback. we've had hundreds of people take the software this month, and NOT ONE user has bothered to provide us with feedback. total absense of user input makes it next to impossible to develop software.

Fantastig HOWTO's and guides...I actually got compiz/xgl working rather quick surprisingly enough. :)

One thing however, I get tearing on video, and while that was easily fixed before using nvidia-settings and setting gl vblank or vsync to enabled. But nvidia-settings is no longer working. I get a ERROR: NV-CONTROL extension not found on this Display. Even though there are no errors in my xorg log, and in fact it mentions that it's loading the extention with no WW's or EE's.

I searched around, but couldn't really find anyone else mentioning they were having this problem, so I figured it was something I did wrong.

As an FYI I'm running a GeForce 6200 AGP...nothing spectacular, but nothing too out of the ordinary either.

Again, sorry if this question has been answered already elsewhere...


I have same thing. I think it's normal. As of now only mesa libraries can be used and not nVidia as one of the GL_whatever is missing. As you are not using nVidia library, nvidia-settings cannot work.

Hopefully nVidia said next driver will include support.

PostPosted: Wed Feb 22, 2006 10:00 am    Post subject: gxl and TV or video overlay on nvidia Reply with quote

I got running Xgl on GeForce4 Ti4200 with nvidia-kernel-1.0.8178-r3 and nvidia-glx-1.0.8178, pentium3 800Mhz cpu.

When I use mplayer to play TV or some avi, using xvideo (-vo xv), it is like a slideshow, even hard to quit.
Using opengl output (-vo gl / -vo gl2) it is much better, but you can still see that some frames are dropped, because it is not fast enough. For bigger resolution of avi you can even see how frames are redrawn - you can see boundary-line between frames moving across the screen...
Using x11 output (-vo x11) it is fast enough, but video cannot be scaled to fullscreen.
Tried also xine with the same results - xvideo unusable, opengl dropping frames...

I am using
Code:
/usr/bin/Xgl -ac -accel xv:fbo -accel glx:pbuffer
in startx.

I have seen something mentioned about pixel shaders needed to have accelerated xvideo, but my graphics card (gf4 ti4200) is supposed to have pixel shaders 1.3 hw support.

Has anybody some idea to get performance improvement for TV or movie playback in Xgl?
Or has somebody some more exact information what graphics card / pixel shaders version / driver version is needed to have xvideo really accelerated?

Well isn't this interesting. I've had Xgl+compiz working for awhile, grabbed the latest overlay and tried building.

Code:

I managed to get it working!

2 things now could make my life better

1- How can you make XGL automaticaly boot instead of normal xorg? I copied a script startxgl that I run at each boot...

2- My video picture in xine isnt quite good... It's fuzzy or doubled... why?


Effects are great! I love that cube

I got the same thing I think. Switching xine/mplayer from xv to x11 fixed it.

I tried opengl driver and X11 driver... can't help

My trouble looks like this http://bleh.mine.nu/Screenshot-1.png

What you see the pink thing at the bottom is the UI... It's that way only in Xgl

Hm, I feel stupid having this problem, but I've gone over the wiki a few times but still have the "GLX_EXT_texture_from_pixmap is missing" http://gentoo-wiki.com/HOWTO_XGL#GLX_EXT_texture_from_pixmap_is_missing problem.

I have a 6600GT running the 1.0.8178 nvidia driver. All necessary packages seem to run fine, and I'm using the CoffeeBuzz overlay from Feb 24. As suggested, within normal xorg I run:
Code:
Xgl :1 -ac -accel glx:pbuffer -accel xv
in one terminal and then
Code:
LD_LIBRARY_PATH=/usr/lib/opengl/xorg-x11/lib/ DISPLAY=:1 compiz
in a separate terminal. Here is the output I get:
Code:
$ Xgl :1 -ac -accel glx:pbuffer -accel xv
_XSERVTransSocketOpenCOTSServer: Unable to open socket for inet6
_XSERVTransOpen: transport open failed for inet6/brick:1
_XSERVTransMakeAllCOTSServerListeners: failed to open listener for inet6
Could not init font path element /usr/share/fonts/OTF, removing from list!
Could not init font path element /usr/share/fonts/CID/, removing from list!
FreeFontPath: FPE "/usr/share/fonts/misc/" refcount is 2, should be 1; fixing.

and
Code:
$ LD_LIBRARY_PATH=/usr/lib/opengl/xorg-x11/lib/ DISPLAY=:1 compiz
compiz: GLX_EXT_texture_from_pixmap is missing
compiz: Failed to manage screen: 0
compiz: No managable screens found on display :1

I also tried running compiz with
Code:
LD_LIBRARY_PATH=/usr/lib/opengl/nvidia/lib/
, just for good measure. As suggested in the wiki, I've tried remerging mesa with opengl set to xorg-x11, but that didn't help.

The wiki also mentions remerging "glx", but there is no such package (I tried remerging nvidia-glx in xorg-x11 mode, and that didn't fix anything):
Code:
emerge -va mesa glx



Then, just for good measure, I remerged everything with the opengl modes suggested in the wiki:
Code:
emerge mesa
eselect opengl set nvidia
emerge nvidia-glx glitz xgl
eselect opengl set xorg-x11
emerge compiz
eselect opengl set nvidia


But I still have the GLX_EXT_texture_from_pixmap problem. Has anybody else encountered this and fixed it? Thanks in advance.

I've got the same problem as strc (on a 6200 card). I can run compiz with --test-mode to get a blue window, but I get "GLX_EXT_texture_from_pixmap is missing" when I try and run it on its own. I also get the same problem if I use the latest cvs of glxcompmgr.

what revision of the overlay are you folks using? try "svn up" in /usr/local/<your-xgl-overlay> to update it and remerge the works. I don't understand how this can still occur if you've used a mesa cvs build.

Oh damnit, I think I know what's wrong. The CoffeeBuzz overlay is at rev 30, but somehow my portage overlay didn't see the alpha version of mesa (only mesa-6.4.2-r1 in the main portage tree). Now I've emerged the CoffeeBuzz mesa-6.4.3_alpha20060224 by path, under xorg-x11 opengl mode.

Now compiz no longer complains about that extension. I get a solid blue screen; I can start a borderless xterm, but gnome-window-decorator won't start:
Code:
$ DISPLAY=:1 gnome-window-decorator &
[1] 30767
$ gnome-window-decorator, Failed to load shadow images

[1]+  Exit 1                  DISPLAY=:1 gnome-window-decorator


Now I'm recompiling nvidia-glx, glitz, xgl, and compiz to use the new mesa. Things are looking up now. Thanks for your swift reply!

I was still using mesa 6.4.2 somehow, pointing emerge at the cvs mesa ebuild fixed it.

A big thanks to CoffeeBuzz for his effort .. everything works ;)

just two question ... direct rendering is supposed to be enabled or not?, i remember it was only ati's stuff ... but now?
did anyone managed to use gdm? i modified it to use xgl ... but it starts x ... i don't mind typing everytime ./startxgl ... but i'd like to end my session, and not to kill it. I got problem too with dbus-session, it isn't exported and some progs don't find it.

I have Xgl running OK now using Xfce4-session (Coffebuzz overlay rev 33, xfce4-session-4.2.3). I have all the basic plugins loaded and functioning fine. However, I have a small issue with my normal userid:

My normal user account can run Xgl and compiz rootless perfectly with all extensions enabled, but when I try to use it within Xfce4, X crashes. The perplexing thing is that a newly created user can run Xgl+compize in Xfce4-session perfectly. I tried cleaning my config files in ~, removing everything but necessary config files (.mozilla/, etc), but that doesn't change a thing. Also I did a diff on 'env' for my 2 user accounts, and the only difference is the username. It seems I'm not the first person with this problem, so has anybody figured out what the fatal config file is? Here is the output of X crashing when I run it under my main acocunt:
Code:
$ startxgl

Any ideas why one user wouldn't have a problem, while another user doesn't? Thanks in advance.

Having not found anything in man emerge or man portage, is there any way of telling emerge to use the overlay directory rather than from the mirrors? Every time I do a world update, it tries (and often succeeds) to downgrade mesa back to 6.4.2 .
Thanks

Theoretically, if the overlay is done right, and your mesa ebuild has a higher version than the one in /usr/portage, it shouldn't downgrade unless you have a dependency on that version by something else (which is probably safe to ignore).

I'd suggest masking the old version, or finding the ebuild (using emerge -puDt) that requires it and adding one modified to not require that mesa version to an overlay.
