Hey all! I've browsed through the NVIDIA Linux forums, namely this thread: http://www.nvnews.net/vbulletin/showthread.php?t=114858 and have come to some reasonable conclusions based on what I found there.
1. Firefox uses XRender to display pages now 2. NVIDIA cards are slow with xrender: http://www.larsen-b.com/Article/290.html Possibly meaning that because of a bug in the NVIDIA driver, XRender does some work it shouldn't have to and therefore spikes in CPU usage. Does gnome-terminal use xrender as well? That could explain its poor performance as well. Also: 3. People who experience this bug will have poor scrolling speed (with at least Firefox) in pages like http://www.tuaw.com/ and http://shame.tuxfamily.org/repo/?cat=1 4. According to http://www.nvnews.net/vbulletin/showpost.php?p=1693884&postcount=40 , NVIDIA knows about the problem. They have created a fix, but it simply hasn't been released yet. They say that the fix "... will be available in a future driver release." I don't know how right I am, but we might just have to wait and see. -- [Hardy] Xorg high CPU usage with 2.6.24 kernel and nvidia-glx https://bugs.launchpad.net/bugs/178400 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
