Dumkiwi: I am not really sure about the KDE ebuilds. Roderick will have to take a look at it. I am pretty sure it requires patching, but I am in no way positive.

ok l33t5!, help me to the last holy Xgl trouble.

I managed to start Xgl on my new lappy [acer aspire 5672 - ati x1400 - intel 945GM - centrino duo].

What i've done:
- xgl-coffee overlay updated and installed [only xorg-server is <1.1.0]
- compiled kernel with agp support as module, back-end included
- no framebuffer support in character device [ATI radeon fb et similia]
- last ati-divers [8.25.18]
- xorg.conf [i've tried 26 different conf ... this one works]

yeah, i know ... i setted it at 60 sec ... i think there's a problem with gnome-session/dbus and compiz ... maybe it's gnome-2.15's fault

Strongly believing that x11-base/xgl overwrites (incompatible) xorg-server.pc.
That files belongs here to two packags
$ equery belongs xorg-server.pc
[ Searching for file(s) xorg-server.pc in *... ]
x11-base/xorg-server-1.1.0 (/usr/lib64/pkgconfig/xorg-server.pc)
x11-base/xgl-0.0.1_p20060606 (/usr/lib64/pkgconfig/xorg-server.pc)
$
In the later Xgl version, sdkdir= is empty and e.g. -DXFree86LOADER is missing in Cflags.

E.g. after emerging xgl it is not possible to correct&direct re-emerge xf86-video-ati, you'll
then get an error regarding missing symbol gRADEONEntityIndex

I am still having this problem and can't seem to figure out a workaround, except for disabling compiz.

Basically, my shift key doesn't work. I am sure that it is compiz because the shift key works in gdm under xgl and it also works fine if I boot the normal xorg server without compiz. I have removed every compiz plugin setting in gconf that had the shift key in it but to no avail.

I wasn't sure exactly what the howto meant when it referred to the water plugin and changing the 'ctrl' key to 'none'. Ie. it is not clear if one should enclose 'none' in angled brackets, set it to disabled, or just delete it. I tried just setting it to 'none' but that didn't help.

There were a few earlier posts that indicated disabling the 'workarounds' checkbox under the 'place' plugin would do it but that did not work for me.

I am at revision 237, although this same problem existed a few weeks ago, I was just out of town and was hoping it would magically fix itself in the newer version.

One more bizarre thing, in gnome-terminal the key combinations ctrl-shift-t, ctrl-shift-w, etc. all work fine. I think this means that the keyboard is setup fine and that the shift key is sending the right signal but that something [ie. compiz] is intercepting the 'shift' key and not behaving properly.

Does anyone know how to solve this or have any ideas how to track this problem down// [my capslock key is going to wear out soon].

Thanks

EDIT: Ok, it seems to work now, it required a reboot (to reload the gconf db I guess...). I am too frustrated now to isolate which plugin was causing it but if I remove every reference to shift in the compiz plugins, disable the workarounds for the "place" plugin, and put "none" in for the water plugin, and then reboot, my shift key works. Hope that helps someone in the future! (yay for punctuation marks!)

Star Dancer thats an odd one, it all works fine for me, what compiz version are you using?

If you haven't tried it yet I would suggest you try compiz-quinnstorm-9999 (its the CVS ebuild not the snapshot)

Vulcano23, while xv runs under Xgl, I find that running video on the underlying xorg-server is the only way to get decent performance, especially for fullscreen video. This works fine with MPlayer, but I don't use MythTV so I can't give you any input there.

My xvinfo is identical to Jupiter1TX's, and xvinfo for the underlying server (display :94 on my system) just gives video-card-specific information.

Thank you both for the replies!

It seems the xv implementation is still very basic. I was able to use mplayer in Xgl, but it seems Mythtv uses some, more sophisticated features of xv and wont work.

In particular my guess is that it uses the following attributes (this is part of the dump from xvinfo in xorg):

neg is a very experimental plugin, if it gives you problems please unload it and report your problems here.
Your assistance will be greatly appreciated.

Ok, just to share my happiness with you mates!!!
My gnome-2.15 comes with only custom.conf to set gdm option ... so i thinked ... why not? let's add a gdm.conf

recently I've once again installed compiz and xgl but unlike a few months ago, I now have artifacts all over the Screen especially when moving windows and rotating the Desktop cube.

I'm running compiz-quinnstorm and the latest xgl.
ATI-Card with latest drivers and Xorg 7.0 and qingy as displaymanager.

Is this a known issue?

Thank you in advance for any help.

Er - mind if I ask, what does dbus do?

I am running xgl (quinstorm 13.2) fine, although I get the "cann't connect to dbus" error. Is this important? compiz seems to be running fine. what do I gain from getting dbus to work?

Thanks!

Hi All,

I recently converted to Gentoo from Fedora, and I'm very happy with it so far. I used the XGL howto to get XGL running, and it's been working well. So, I've had Gentoo installed for a few months now and thought it might be time to run a full system update.

But I'm having a bit of trouble doing an:

emerge -uDNv world

I get the follwoing error:

Calculating world dependencies ..... ....
!!! All ebuilds that could satisfy ">=gnome-base/gconf-2.14" have been masked.
!!! One of the following masked packages is required to complete your request:
- gnome-base/gconf-2.14.0 (masked by: ~x86 keyword)

I did update my xgl-coffee overlay first using svnup.sh, not sure wheather that represents a problem or not.

I tried adding gnome-base/gconf to package.unmask, but it didn't seem to change things. Surely I managed to emerge gnome-base/gconf before, what's the problem now?

Any help or advice is greatly appreciated.

Cheers,

jcat

Thanks for the fast reply!

It seems as though I'm running gnome-base/gnome 2.12.3, but emerge aslo says that's the latest verion available.

I assume that some of the compiz stuff is supposed to be part of gnome 2.14 then. Is that where the problem lies?

So, should I be using gnome 2.14 instead? I take it that's the testing version?

Thanks again for your help!

Cheers,

jcat

Compiz is not part of Gnome, but it was written to run under Gnome and has been patched so it also runs under KDE and other environments. The Gnome experience tends to have fewer problems.

You might want to consider whether you want to install Xgl right now. It's outstanding software that has really enhanced the way I interact with my system, but it is alpha software that can require a lot of tweaking before it works with some combinations of hardware and software. If you value stability, it's not yet there for you.

As far as I know, most people running Gnome+Xgl are on 2.14 I don't know if it will run at all with 2.12. You will also be unmasking CVS versions of mesa, and very new versions of cairo and glitz, all of which will require unmasking of a lot of other packages to work. You have to be running xorg-x11 7.0 or later for this all to work.

In short, before taking this step you might want to consider changing over from the stable tree to the testing (~x86) tree and updating all the packages involved before installing Xgl. I run a testing (~amd64) system and find most software in testing to be stable enough for a production system, though others would disagree with that.

You could also stay x86 but keyword everything related to Gnome and xorg-x11 to get more recent releases, and then try installing Xgl.

If you do want to take either of these approaches, there are a lot of people in the forums who will help you out along the way. And if that's not for you just yet, then you might look into downloading the Koroaa Xgl LiveCD to see what Xgl is like.

Sorry mods, I was wondering if this was the correct section! :lol:

Hi sternklang,

I'm already running XGL, and have been for about a month. It's great!

So XGL definitely runs on gnome 2.12

I followed http://gentoo-wiki.com/HOWTO_XGL when I installed and it was a very smooth install, but it doesnt mention anything about using gnome 2.14 or to consider using testing instead of stable because of updating issues. In fact it doesnt mention anything about how to update the system afterwards at all, I think it would be a good idea if the howto included a section dedicated to updating your system after XGL install.

So I might just try and add all the packages I need from testing to package.keywords as you said earlier.

If I did update to testing, what's the proceedure? Are there any good howto's on htat topic? Would there be any implications changing to testing seeing as I'm already running XGL? Would this affect the need to use the xgl-coffee overlay?

So many questions. Sorry to be a pain! :oops:

Hope you can help.

Cheers,
