X31 + Compiz Fusion Not Working

[camdecoster]

I recently installed Linux Mint 4.0 on an X31 and can't get Compiz Fusion working. When I try to enable desktop effects I get a flicker and then an error message which says something like "unable to enable desktop effects." I know the 16MB Mobility Radeon isn't super powerful, but I thought I had read on this forum that folks had gotten CF to work. Could my configuration me hosed? Where could I look to fix things? Any responses are appreciated.

I had Beryl running in PCLinuxOS 2007, but the window titlebars went blank when maximised. That is a common problem with the X31 when using Beryl, as there is not enough VRAM. I know Beryl is an earlier verision of Compiz Fusion, before they both merged back, but I thought I'd mention it.

I got it working last night by adding the following to the Device section of my xorg.conf file:

Option "AGPMode" "4"
Option "AGPSize" "64" # default: 8
Option "RingSize" "8"
Option "BufferSize" "2"
Option "EnablePageFlip" "True"
Option "EnableDepthMoves" "True"
Option "RenderAccel" "true

I found those instructions on the ubuntu forums at the following link (last post on the page):

To be honest though, I don't really know what all those options do.

There is a Linux area in this forum. You will find more help there I think.

I am using Kubuntu 7.10 and compiz-fusion is working on my X31 (specs in the sig) - despite being a little slow and sometimes hesitant its usable. I used the following steps:

Commands:

apt-get install xserver-xgl
apt-get install compiz compizconfig-settings-manager compiz-kde emerald

<reboot>

compiz --replace

Update:

I had to uninstall xgl server and go with the ATI driver instead. This improved the performance significantly.

Here are the updated steps:

* Remove the XGL server if installed:
# apt-get remove xserver-xgl

* MAKE BACKUP OF THE /etc/X11/xorg.conf
# cp xorg.conf xorg.conf.backup

* Reconfigure the Xserver
# dpkg-reconfigure xserver-xorg
chose the ati driver

Make the Device section in xorg.conf look like this:

Code: Select all

    Section "Device"
  	Identifier	   "ATI Technologies Inc Radeon Mobility M6 LY"
  	Driver		   "ati"
  	BusID		  "PCI:1:0:0"
  	  Option	  "UseFBDev"		"true"
          Option          "AGPMode" "4"
          Option          "AGPSize" "64" # default: 8
          Option          "RingSize" "8"
          Option          "BufferSize" "2"
          Option          "EnablePageFlip" "True"
          Option          "EnableDepthMoves" "True"
          Option          "RenderAccel" "true"
    EndSection
  

* reboot
* # compiz --replace
