So, yeah, compiz has this wonderful thing where you can set it to "unredirect fullscreen windows". What I find this means is that I can run games under XGL in full screen mode and get extremely good performance. Except Vendetta. For some reason, when launched from within XGL, Vendetta only sees a max resolution of 1024x768 (instead of 1280x1024) and crashes if I set full screen mode. I should note, for the record, that Vendetta works fine under normal X. Further info:

Just wondering if you guys had any thoughts...

I wasn't going to bother anyone with this, but I have exactly the same problem.. I don't know if you have heard of xlaunch. It's a script (in the portage-xgl gentoo overlay) making it possible to launch opengl applications in a new X server. Since a week or so, vendetta crashes while updating.

I used to run a second X server for OpenGL games, but the latest nvidia driver has been crashing on me when XGL + another X server (I know, techinically Xgl uses 2 X servers, so I guess the nvidia drivers have problems when there are 3 X servers running?). After finding that a good-ish number of OpenGL games work fine with that unredirect option, I was kinda hoping that VO would. Alas, but no.

Yeah that is about the same as that xlaunch script, just manually starting a second X server. I guess we have to wait for the nvidia 9*** drivers..

I wonder what will come first, new player-flyable ships or the nvidia drivers.

.

Or you could just not use xgl... I gave it a go for a couple of weeks and it eventually started to annoy me. The virtual desktops do not scale very well, four is clearly not enough for my use (I need at least 8), the whooshing things take time I want to spend doing more useful things, the whindow wobbling makes it illegible whilst moving and is annoying. The transparrencies and zoom and window shadows are nice though... but do not really justify running xgl. So, I have it off.

Oh sure, that's not the problem, I know I can just NOT use it. 4 virtual desktops just happen to be enough for me and most of the REALLY fancy effects (like wobbly) I've turned off, since it gets annoying. Some other effects I DO like, and since you disliking compiz/xgl is no reason to quit using it, I'll be waiting for the new nvidia drivers :)

Indeed. I'll probably go back to using it if they manage to get their desktops to get recognised as proper virtual desktops, so I get little previews of them all at the bottom of the screen and can easily switch between them.

Ah, so you probably don't use Gnome. since it works in Gnome for me. I hate the fact that it is impossible to change the number of virtual desktops even though I only use 4.. Things just have to mature and I think the change of course started by quinn storm and Beryl may be beneficial, but I'm still waiting for the Nvidia drivers..

hmmm... not sure how, but I seem to remember seeing an XGL demo on youtube that had usable desktops on all 6 faces of the cube.. I dunno, I'm waiting to migrate until it's fully supported in non-GNOME environments..

edit- KDE?? I *like* to pretend I'm using a UNIX machine, okay? no fancy-schmancy HAL-filebrowser for me :P~~

If you're using KDE, I guess you'll have to wait for KDE 4.

Edit: Oh. and there is http://www.kde-apps.org/content/show.php?content=46021

roguelazer: OMGWTF!! NVIDIA BETA DRIVERS WITH DIRECT RENDERING UNDER XGL :P

Yay, I switched from XGL to AIXGL and from Compiz to Beryl and am using the beta drivers, so far everything is running fine..

Yay

Ah, so you probably don't use Gnome. since it works in Gnome for me.

Correct, I use KDE on the machine with the good graphics card. I have GNOME on my Debian machine... but that has a Geforece2 card that needs legacy drivers, and they do not currently compile against SMP 2.6.16, 2.6.17, or 2.6.18 kernels (at least not in testing, unstable has a .17 build coming my way).

I hate the fact that it is impossible to change the number of virtual desktops even though I only use 4

You can you can you can!

Run gconf-editor
Navigate to / -> apps -> compiz -> general -> screen0 -> options
Set size to the number you want.

It will make a shape with 2+size faces (where 2 are top and bottom). I am not sure how well it works for size <4, but it worked nicely with a 10-sided thing. The problem I then had is it was hard to navigate directly to some desktop as it was not KDE-friendly.

Oh. and there is http://www.kde-apps.org/content/show.php?content=46021

From description I'd want to wait till around 0.5 to use that..

maybe everyone is looking for this...

i run Ubuntu with XGL/Compiz and i couldnt get really any games to play in full screen or in full speed. I was also getting video errors and the games were always crashing, after i did this all games work perfectly. let me know how you go.

I'm pretty sure that all that it runs the game on Xgl's parent X server. Probably not a great idea, because that means xgl loses direct rendering, and those xhost lines are really bad for security unless you have X firewalled away.

it just allows you to run selected apps/games outside of XGL witch is why it works, i am using it and it works great. as for the security issue, i am yet to have any issues, maybe change it around some if you like.

I think it's like xlaunch, but not necessary anymore if you have the new nvidia drivers.
