All the windows are funny, I don't know, it's hard to explain. I would take a screenshot but I don't know how. Oh yeah, I'm using XFCE4.2.

EDIT: Got the next best thing.

EDIT: Ok, just started up beryl-manager in terminal and it's giving me the following:

Anyone got any ideas then?

If you are using the same X1900XT that is in your sig your probably out of luck for now. I believe the fglrx driver only works with XGL at the moment, although AIGLX support is rumored to be on the way. I'm using XGL with a X1950 Pro and it is working great.

It is partially working as you have seen yourself, but too much "partially" and not enough "working".

Hmm, well I tried emerging xgl but it says no ebuilds to satisfy xgl. I've added the keywords and unmask.

Are you using the xeffects overlay? you can get it from layman if you aren't. It should have xgl for you, the version I'm using from it is x11-base/xgl-0.0.1_pre20061108

Ok, I've now got the overlay and XGL installed and I've also installed GDM, the only problem I've got now is, when I run gdm, it'll go to a black screen with the watch cursor and just hang there untill I Ctrl+Alt+Del.

Did you follow the instructions here: http://wiki.gentoo-xeffects.org/XGL#GDM

Also, did you verify that DRI was working before setting up Xgl?

Yep, followed that howto you linked. Not sure about the DRI, I think I did, can't remember for sure though.

EDIT: I just read in another thread that DRI is not used with XGL.

EDIT: Ok, I've just made another xorg.conf and run aticonfig and when I run gdm, it works. The problem is though, the screen is all messed up. I'm sure I've missed adding something in the xorg.conf but can't remember what.

You don't get DRI when using XGL, but XGL needs it to work initially. What happens with XGL is that you get 2 X servers, the normal one and the XGL one that runs on top of it. The normal one needs DRI so it can display XGL, but XGL itself doesn't get DRI, and that is where all your apps run. So it is a good idea to check and make sure opengl and DRI works fine before switching to XGL.

Can you post your xorg.conf? Mine is quite simple at the moment, this is a relativley new install, but works great for me with XGL:

also, you've probably already done this since you were following the howto, but you need to make sure beryl is starting when you login as well: http://wiki.gentoo-xeffects.org/Beryl#Gnome_Users

How do I copy from terminal? I thought it was Ctrl+Shit+C but that doesn't seem to work.

Copy and paste into links? I don't know... never needed to before.

When you say the screen is all messed up, is it like the image you posted at the beginning?

No, it's all garbled and when I login using the GNOME login I can just about make out in the background that it's in Xorg, XFCE hasn't been loaded.

EDIT: Here's a photo of it.

I've seen things like what you got in your pic there before, usually has to do with memory not being written to or read from the right place.

Just to make certain everything hardware wise is set up properly, comment out the changes you made to gdm's custom.conf and try logging on like that. If you get in okay, run glxinfo to make sure you have DRI working, and then try an opengl program if you can (glxgears if you don't have anything else). (glxinfo and glxgears are in the mesa-progs package).

Tell me how that works out. At the very least you should be able to post your xorg.conf and /var/log/Xorg.0.log files more easily from XFCE then from the terminal. It will be easier to find problems if I can see both of those.

Just checked glxinfo and DRI is working and I get 112884.020 FPS in glxgears. I'm make the changes to the custom.conf and see how that goes.

EDIT: I just tried setting Beryl as my Window Manager but it's coming back with an error:

Nebvin · Posted: Thu Dec 28, 2006 11:41 pm Post subject:

Yeah, if you commented those lines in custom.conf then Xgl wont run, so Beryl will give you that error. It appears everything else is working good though, except you might be loading an incorrect session in gdm (should be able to pick XFCE from the sessions menu in gdm, it should be easy to find, just depends on the theme you have).

So we know your hardware is setup good. (which is disappointing because I'm running out of ideas to get this working for you)

You can put those lines back into gdm's custom.conf and try again

At the moment, I can't think of anything else to try other then recompiling xgl, beryl, and all their dependencies. go back to the wiki I posted above and make sure you emerge those packages it asks for again. Perhaps your troubles are from not having the xeffects overlay from the beginning.

Okay, thanks for your Nebvin, really appreciate it.

If I can figure out how to copy the text in terminal, I'll post the xorg.conf.

EDIT:

Looks pretty good, there are some redundent parts due to the way the file was created, but it is set up right. Some things to try:

Add this line to disable AIGLX in the ServerLayout section:

Jimi... · Posted: Fri Dec 29, 2006 6:51 am Post subject:

Well, I decided to reinstall Gentoo, I made a load of cockups before so it was probably for the best.

I've still got a problem getting Beryl to autostart though, I followed this howto using the startxfce4 method. And even though I can get it to start fine by starting it through terminal, I can't see any difference and when I try to select Beryl as the window manager when you click the ruby or whatever it is, it looks as if it's changing, but doesn't.

EDIT: This is the output in terminal when trying to load a theme in emerald.

you mentioned above that when you started X you got a black screen?

I had the same problem although i did get the nvidia logo before the black screen.

I added the following lines to my monitor section which seemed to solve the problem

Jimi... · Posted: Fri Dec 29, 2006 11:14 am Post subject:

Hi, thanks for your suggestions. I'm running 0.1.4. Unless you use XFCE4.4, the methods listed in the howto I linked are the only ways to autostart Beryl, for XFCE atleast.

EDIT: I got Beryl and XGL working, Beryl still won't autoload and I'm still getting that screen corruption, but for some reason, it doesn't happen all the time.

Glad to hear you've made progress.

If you are still getting that display corruption like you showed in http://img179.imageshack.us/img179/9138/pc280017te0.jpg there is a couple other things to try as well, although my advice at this point is just boiling down to trial and error. What kernel are you using? What version of ati-drivers are you using? I'm using 2.6.19-beyond2 with ati-drivers-8.32.5. Although unlikely, your version of ati-drivers might be causing it, or something wierd with your kernel.

Doesn't work rmh3093, Beryl still doesn't boot and I still get a corrupt display.

I'm using the 2.6.18-r6 kernel and the same drivers as you Nebvin.

Have you tried disabling gdm and using the startxgl script to see if you get any improvement?
