desktop effects could not be enabled

schneidz · 10-03-2009, 05:54 PM

hi, when i click on system -> preferences -> desktop effects, i get this error.
if i type in compiz from the command line i get these errors ('compiz --replace' changes the windows to have no title bars -- i have to type in 'metacity' to get it back to normal):

Code:

[root@localhost ~]$ lspci | grep ATI
01:00.0 VGA compatible controller: ATI Technologies Inc Mobility Radeon HD 3400 Series
[root@localhost ~]# compiz
compiz (core) - Error: Screen 0 on display ":0.0" already has a window manager; try using the --replace option to replace the current window manager.
compiz (core) - Fatal: No manageable screens found on display :0.0
[root@localhost ~]# compiz --replace
compiz (core) - Fatal: GLX_EXT_texture_from_pixmap is missing
compiz (core) - Error: Failed to manage screen: 0
compiz (core) - Fatal: No manageable screens found on display :0.0
[root@localhost ~]# metacity

how do i enable desktop effects on my computer ?
thanks,

First of all, never run X (or compiz) as root.

Second, install compiz-manager via yum and use that to launch compiz.

Third, do you have the drivers from AMD installed?

i think so, my gui works so some sort of graphics driver must be installed. i dont know if the amd one is the default (i didnt physically go to the amd website to download and install anything, so possibly not -- lsmod shows that i am using radeon).

by and by, this is the x86-64 live-usb version.

i get a cube with 4 white sides and two blue sides when i run compiz-manager:

Code:

[liveuser@localhost ~]$ compiz-manager

But compiz requires hardware acceleration, and that won't happen without the manufacturer's drivers.

WARNING:

I also have FC11 and had a Radeon card, but I tried 3-4 times to install the driver and it almost bricked the whole system every time. I got an Nvidia card out of another computer and its drivers work okay (but still some issues, including the text-mode terminals (without X running) not working).

Yeah, the radeon driver that comes with F11 certainly supports 2D acceleration for your card, but no 3D acceleration. You need the proprietary driver. I'm not sure how well it works with F11 these days, but you might find this link helpful:

... this means you do not have HW acceleration.

Wow, that is completely wrong.

Xgl is not necessary and definitely not wanted. That is an informational message only. Xgl has never been supported on Fedora, so even if he had the correct drivers installed, he would still get that message.

^ when i did 'yum install kmod-fglrx' i got kmod-fglrx not found and i have rpmfusion repo installed.

i just installed the driver i downloaded and when i restarted and (after the blue/ lite blue/ white fedora-11 loading screen) the screen would just go black. i tried ctrl-alt-f1, ctrl-alt-f2, ctrl-alt-backspace, ctrl-alt-del -- nothing seemed to do anything.

so i guess i will reinstall the live-usb and go without compiz-fusion (its practically useless anyways but still fun to use).
