View Full Version : Unsolved Window Blur freezes system completely

Whenever I enable Window Blur my system completely freezes. Ctrl+Shift+Backspace doesn't work, the mouse won't move, nuthink. 's a bit annoying, cos transparant windows without blurred background look a bit shoddy.

I'm using Ubuntu Hardy Herron 64bit, my graphics card is an ATI Radeon X800 using the open source drivers that come with Ubuntu, I have 2GB RAM and an AMD Athlon 64 X2 Dual Core 4200+.

Any help with this would be grately appreciated.

Thanks.

This is an issue with the open source drivers, which do not properly support the needed functionality for blur. If you want to use blur, you'd have to use the fglrx drivers.

Or, afaik, Xgl, which will remove direct rendering, but might be preferable to fglrx

It doesn't work with Xgl + the open source drivers, either. It slows down X till it's unusable, and never blurs anything.

The reason for this is that compiz is essentially kicked into software rendering mode because mesa panics and quits out. Yeah, you'll have to use fglrx & Xgl at the moment as those are the only drivers and setup that support things like fbos and fragment programs. I don't understand why people insist on using the free driver and Xgl / AiGLX or fglrx and AiGLX. Unless you only want to use free software, which is fine by me.

But if you are going to use fglrx, use Xgl. It's faster anyways.

Blur works just fine with fglrx without Xgl :-)

Not anymore(especially since it became horrible after the new codebase came in), though you do get tearing on AiGLX :(
