I've been trying to use the Expo feature in Ubuntu as I have in Kubuntu. But whenever I toggle windows to pan out everything becomes incredibly slow. i'm pretty sure this isn't a hardware issue. Has anyone else experienced this? I'm using a g7-1070us currently.

Can you please provide some background on the Toggle/Expo feature?

I'm not at my laptop now but it's a feature under KWin. It displays every window in your workspace or all workspaces visually. It's accessible either by keyboard shortcut or I think placing your mouse in the top left corner?

I believe you are referring to Present Windows. This is a Desktop Effect - and so dependent upon the number of windows and the performance of your GPU. What graphics card/driver are you using?

I have an integrated graphics card with my g7-1070us http://www.newegg.com/Product/Product.a ... 6834157801.

I don't think this should be a problem honestly. I've used similar features on Ubuntu with this computer as well as old computers with perfect response times.

Intel graphics are usually fine. Does this slowness persist once you have finished using the desktop effect?

No it's only when I activate it.

What do you have under "scaling method" in the desktop effects control panel? (System Settings > Desktop Effects)

Crisp. That's faster I believe? And yet still slow on my system.

I just switched the Compositing type from "Xrender" to "opengel" which sped things up remarkably however.

Actually I take that back. OpenGL tends to crash now. Hmm

It is expected that XRender is slower, however OpenGL should be stable never the less. Which graphics card and driver are you using? The Proprietary Nvidia drivers are usually fairly good for Nvidia hardware, and the Open source driver works very well for Intel hardware.

I used an integrated graphics card and have whatever driver Kubuntu must have originally installed. I reenabled opengel after a reboot and it works fine again. Not sure why it failed before when I enabled it, enabled Xrender, then enabled opengel again.

Glad to hear that OpenGL works properly and the effect is speedy as expected under OpenGL.
Marking as solved.
