Compiz: was OK, now barely so. Why?

[theYinYeti]

Yesterday morning, I decided to try Compiz, at last. I liked it, and actually found many things good for productivity.

gdm (Xgl) started OK, and compiz ccp started OK too.

 

Yesterday evening, I did my occasionnal urpmi --auto-update --auto-select. Now:

- Either I update-alternatives --config gl_conf and choose "ati", and then Xgl starts, but Compiz fails;

- Or I update-alternatives --config gl_conf and choose "standard", and then Compiz starts, but Xgl fails after logout.

 

The solution so far is to choose the "ati" set of GL libraries, and setup my Gnome session to start ~/bin/compiz.sh, the contents of which is:

#!/bin/bash
export LD_LIBRARY_PATH=/usr/lib
compiz ccp &

 

But I didn't need this trick before. Why now? All I know is that kernel changed from 2.6.22.12-laptop-1mdv to 2.6.22.18-laptop-1mdv, but it is probably irrelevant since the problem remains with the former kernel, so it must be because of another update... I have no idea what else was updated.

 

Do you think there is any side-issue or risk with using the above trick?

 

Yves.

 

[edit:]BTW, the compiz error (without the trick) is: "Fatal: GLX_SGIX_fbconfig is missing".[/edit]
