XGL (part 2)

[Ricky]

As of a few days ago, when I try to start Xgl I get "no screens found" when I try and start with the following command:

Code: Select all

Xgl -ac -accel xv:pbuffer -accel glx:pbuffer -layout Single

my xorg.conf is here: http://s88382932.onlinehome.us/files/xorg.conf

(standard X starts up fine. On a somewhat related note, I would get "no screens found" before when trying to start Xgl in 24-bit depth, but it would work find in 16. Plain X can do either.)

[Treborius]

using Overlay 17 I can't compile xgl, I get this error:

Any thoughts?

Fixed in revision 18

i have this error with revision 21 again ...

[Belgabor]

How can i increase the shadow size? I thought it was a plugin but it turned out that it isnt that. Is the shadow built into compiz? How do i change the size?

You can't. The shadow is now done by the decorator which at the moment you can't configure. Obviously you can try hacking the source, but you're on your own there (at least from my side).

[Seph64]

Is there anyone here who knows why XGL and gnome Window Selector/Switcher functions don't play nicely together? The Window Selector/Switcher function keeps crashing when in Xgl/Compiz. Just curious.

[rob2687]

Works fine here. Could be a bug.

[StringCheesian]

Thanks, I got it to compile cleanly now, great work everyone
It runs great overall, and I need to play with it some more, but there are a few things I'd like to notice:
First of all, when I play a video with mplayer -vo xv, it will play just fine, until I go fullscreen. At that moment my cpu usage goes 100% and I get ~1fps.
Resizing the window is fine, without much increased CPU, until I reach a certain 'magic' point, afterwhich it gets 100% cpu usage and ~1fps

Is that magic point a power of 2? Like when windows get wider or taller than something like 256, 512, or 1024? Maybe XGL is not handling it very well when the window gets larger than your video card's maximum texture size.

[piwacet]

Wow this is good stuff. Got everything working on AMD64 3800 X2 with Geforce 6200 PCI-E with 256MB on-card memory.

Using xfce4. Have imwheel hack that allows me to switch desktops with mouse-wheel when mouse pointer is over desktop or taskbar.

Everything works well, including opacity.

Thanks everyone for help and input on this forum.

Excellent. Care to share how you setup xfce4? The solution on gentoo-wiki doesn't seem very complete to me. My solution was to create the startxgl script as described on gentoo-wiki. Then copy xinitrc from /etc/xdg/xfce4/xinitrc to ~/.config/xfce4, comment out the session manager stuff and then start compiz from there. I also couldn't make the session manager technique work very well except to delete any existing sessions so it falls back to the default and then ensure that I didn't save any new sessions on exit which again doesn't seem like a great solution so still better to go without the session manager and use the custom xinitrc script it seemed to me. Anway I'm always interested in better ways to do it.

Sorry I'm in a bit of a rush right now but I'll post my scripts:

Code: Select all

magenta@Nautilus ~ $ cat .startxfc
Xgl :1 -ac -accel xv:fbo -accel glx:pbuffer &
DISPLAY=:1 xfce4-session &

Code: Select all

magenta@Nautilus /etc/xdg/xfce4-session $ cat xfce4-session.rc

[General]
SessionName=Default
SessionName[de]=Standard

# Disable management of remote clients by default. The user
# has to explicitly enable this for security reasons.
DisableTcp=True

# This the default session launched by xfce4-session if the
# user hasn't saved any session yet or creates a new session.
[Failsafe Session]
Count=4
Client0_Command=compizrc
Client0_PerScreen=False
#Client1_Command=xfce4-panel
#Client1_PerScreen=True
Client2_Command=xftaskbar4
Client2_PerScreen=True
Client3_Command=xfdesktop
Client3_PerScreen=False


# Default splash screen selection.
[Splash Screen]
Engine=mice

(I don't like the xfce4 panel, hence commented out.)

Code: Select all

magenta@Nautilus /usr/bin $ cat compizrc
DISPLAY=:1 LD_LIBRARY_PATH=/usr/lib/opengl/xorg-x11/lib compiz gconf &

DISPLAY=:1 gnome-window-decorator &

DISPLAY=:1 imwheel -f -k &

And, lastly, imwheel:

Code: Select all

magenta@Nautilus ~ $ cat .imwheelrc
"xfdesktop" 
None, Up, Alt_L|Control_L|Right
None, Down, Alt_L|Control_L|Left

"xftaskbar4"
None, Up, Alt_L|Control_L|Right
None, Down, Alt_L|Control_L|Left

I would start this with

Code: Select all

.startxfc

In my user's home directory (make sure it has a valid path). (No X-server running, do it from console, this will start the x-server for you.)

[Milridor]

Great work!!

Everything is working fine for me but gnome-window-decorator

I get this error:

The program 'gnome-window-decorator' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadValue (integer parameter out of range for operation)'.
(Details: serial 120 error_code 2 request_code 94 minor_code 0)
(Note to programmers: normally, X errors are reported asynchronously;
that is, you will receive the error a while after causing it.

option to change this behavior. You can then get a meaningful

It must be a permission problem because as root, it works

Everything is really working good here. Can anybody tell me how to set the options for compiz plugins? In gconf-editor I cannot see a plugins section. So please, how is this done?

I don't know, I can't see the current size when resizing, I'll try to play with some of mplayers options and see if I can find out something that way.
I saw that there are also people that have mplayer and fullscreen video working properly :s

--edit
It's a bit weird:
I have a video of 768 x 432, and when I scale it to (about) 964x542 it sometimes runs fine (fast) (although the screen is fux0red at some scale levels), and other times it is really slow. So this is the breaking point, depending on ... what?

everything ok for me, but Xgl becomes totally too slow when I'm emerging something. Is there a solution for this?

As of a few days ago, when I try to start Xgl I get "no screens found" when I try and start with the following command:

Code: Select all

Xgl -ac -accel xv:pbuffer -accel glx:pbuffer -layout Single

my xorg.conf is here: http://s88382932.onlinehome.us/files/xorg.conf

(standard X starts up fine. On a somewhat related note, I would get "no screens found" before when trying to start Xgl in 24-bit depth, but it would work find in 16. Plain X can do either.)

Try changing the resolution in 24-bit depth to 1024x768. Probably has something to do with the amount of memory on the card, I guess.

[vdemeester]

Note that if you want have a compiz version installed and you ant to add a feature like the alt-tab patch (link), and if you have another plug-in compiled (without compiz - like a opacity plug-in), you have to re-emerge compiz and the plugins.

I think I could explain this better but.. oO

[MusclePup]

Well I got Xgl and Compiz working (somewhat) on a ATI Mobility IGP U1 this chip has had full DRI excel. for sometime now and gl stuff screensavers and other programs worked well. Now that Xgl and Compiz are running I can see there are many redrawing problems... it seems that if you don't open any windows the desktop will draw correctly and effects like the menus looks nice and are useable but still not up to speed with what I have seen this chip do ( xcompmgr works better with this chip currently ) I also don't get any window decorations like many others say. So what do you think? are these above issues related to the OSS radeon driver , Xgl or both ?

I would love to see Xgl working on older hardware also... my G3 400Mhz iMac and it's 8MB Rage 128 pro with OSX 10.4 produce smooth effects so I have hope.

[Da Fox]

I also don't get any window decorations like many others say.

Define "window decorations"
Are they not just the title bar and window border? :/
