HowTo: minimize CPU usage when scrolling websites with Beryl

[franestepona]

As the title says, I was looking for a solution to minimize the CPU usage since I surf the web quite a lot and it was a little bit annoying. I´m using Swiftfox, but it should work in firefox as well. The problem was the sooth scrolling, to inactivate it go to Edit-Preferences-Advanced and uncheck smooth scrolling.

Scroolling still requires lot of CPU usage, but much better now, hope this help some of you.

I found disabling the "disable gl yield setting" in the advanced beryl options in beryl-manager greatly improved scrolling.

Where is that option? Cant find it

[ffi]

In the right click menu of beryl-manager (the thing in the system tray)-> "Advanced Beryl Options"-> "Disable GL Yield Setting Use this to fix some redraw bugs" and untick the option.

Well looks like iI dont have that option, I'm using beryl-manager 0.1.4. Thanks for the advice anyway. I'll try to find that option in the next updates.

This option is not available in 0.1.4 and I do not remember it ever being available in 0.1.3 CVS.

Strange :???:

maybe it's graphics card specific?? I have an nvidia 6600GT

[franestepona]

Yeah that could be a reason, I have an ATI mobility Radeon. I'll check that out to see if i can find that option somewhere. But maybe it's just that my graphic card dont support it. Thanks for the advice anyway.

Confirmed a no-go on a ATI Mobility (using the radeon freedom drivers).

Too bad, the option isn't there because disabling it fixed the exact problems you described....which I think might have appeared since Beryl 0.14, but I am not sure, I could have been playing around with settings too ](*,)

and to think my obssion with xgl/compiz started hoping it could fix the smooth scrolling problems of Opera, which turned out to be a very very long standing bug of Opera Linux/Mac/BSd and Solaris and which was finally fixed this month (for Linux at least not Mac :p )

Anyway it still might be useful for other nVidia users....

Using todays SVN with the /etc/drirc "hack" (http://bugs.beryl-project.org/trac/ticket/37) not only fixed the maximized window problem but also boosted overall performance. Maximized browser (Firefox) shows a 100-130% FPS boost. Scrolling is still jittery but not as much as before. This is using radeon driver. Note: using the ati xorg driver should also work since ati is just a wrapper to three different drivers, including radeon.

Off topic, but what gtk theme is that? I like it.

I don't have the option here on Beryl SVN 0.1.5

[franestepona]

The gtk theme is BlueHeart combined with "fadeout" emerald theme. By the way AgenT How did you did that trick?

[franestepona]

Uh sorry I just realized you posted the link, thanks I'm gonna try that out.
