[Ubuntu-x-swat] [Bug 877438] Re: [8xxx] Unity/compiz has sluggish performance on dual-head with nvidia driver
Have been reminded of this bug, and thought I'd post a follow-up on my own experiences. I noticed that my desktop would run smoothly at first, then once I had a few windows open, it went slow. I used the nvidia-smi utility to monitor the memory usage on the GPU, and noticed that as I opened more windows, the memory usage would reach 90-95%. Once it reached that level, the desktop became very slow. If I closed windows until the memory usage dropped before 90%, everything sped up again. My solution was to purchase another video card. The old one had 256 MB of video RAM, the new one has 1024, and thus I don't reach that troublesome state any more. People with laptops may not be able to apply this solution. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to nvidia-graphics-drivers in Ubuntu. https://bugs.launchpad.net/bugs/877438 Title: [8xxx] Unity/compiz has sluggish performance on dual-head with nvidia driver To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/877438/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp

PS. On current desktop, with one browser (Chrome), Thunderbird, Pidgin, and six terminal windows, I'm using 400 MB of video memory. One could argue that this is excessive? It implies that you really need a minimum of 512 MB of video memory to use Compiz now.. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to nvidia-graphics-drivers in Ubuntu. https://bugs.launchpad.net/bugs/877438 Title: [8xxx] Unity/compiz has sluggish performance on dual-head with nvidia driver To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/877438/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
