View Full Version : Bug: Ubuntu 7.10 freezing only when using Desktop Effects (ATI)

Hi Ubuntu'ers,

I removed Windows XP from my stationary computer and laptop last week and installed Ubuntu 7.10. My stationary computer is a:

Intel(R) Pentium(R) D CPU 2.80GHz
RV380 [Radeon X600 (PCIE)] ATI Technologies Inc
2GB RAM

I did try to enable the restricted ATI driver, but that messes up Xorg completely. Disabling the restricted drivers makes everything work. Almost...

A completely fresh install of Ubuntu will freeze during usage with Desktop Effects enabled. The issue is very random and blocks Ctrl + Alt + Backspace. Also, I cannot switch to other terminals. I can move the mouse, but nothing reacts to clicks. The keyboard doesn't respond at all.

I haven't experienced this issue on my laptop which is an IBM T40.

Disabling Desktop Effects all together completely removes this issue. However, the cool effects and modern look disappears :)

I realize that other topics on these forums are very similar, but I found it hard to get a proper solution to fix this problem, and sometimes the issues differ substantially (one poster concluded that the freeze-up only happened during heavy usage, I've experienced it while doing work in the terminal).

Is there a solution? If no, I hope the information I provided can help fixing the bug. If yes, can someone point me in the right direction?

Regards,
Dan

BTW, I really loooove the recent versions of Ubuntu :)

I'm having the same problem with a Radeon 9600. It seems that not only Compiz, but also Google Earth causes the complete lock-up. I can only assume that any 3D acceleration will lead to it eventually.

I've seen a lot of posts, but no solutions.

Anyone?
