Binary package hint: nvidia-glx
I tried using the nvidia-glx proprietary graphics driver on Ubuntu Feisty. However, the driver is completely unusable on my system, it messes up the entire screen with graphical noise and a lot of glitches, for example:
1) When scrolling up or down in any widget, the lines get mixed up. This applies to lists as well as textboxes and every other control that has scrollbars. I observed it in Gedit, Gnome Control Center, Synaptic, Gnome Terminal etc. pp.
2) Using the driver causes the System to crash withaut any apparent cause. I haven't been able to find any steps to reproduce these crashes, they seem to happen randomly.
3) The area that was obscured by a window or menu is not properly redrawn when the window is moved or the menu is closed. The formerly-obscured area is filled with graphical noise, every now and then mixing in what seems to be distorted pixmaps from some kind of cache (see below for the origin of these pixmaps)
4) The pixmaps that show up in these areas seem to originate from some kind of cache. For instance, on one occasion i spotted the background image from a website which i visited with firefox some minutes earlier. On another occasion, it showed what looked like a distorted screenshot of evolution, probably cached by the X server.
5) The most interesting observation is: This "screenshot" of evolution was actually from evolution running on Edgy Eft, wich is installed on another partition of the same machine. I was quite perplexed by this, but its a fact: I never configured evolution in Feisty, so there are no emails in my inbox. The "screenshot" however clearly showed emails that i had received earlier that day when running evolution on Edgy Eft. On this machine, Edgy and Feisty are installed in different partitions, but they share a swap partition. My guess is that Edgy's X server cached the pixmap of evolution, that it got stored in the swap partition, and that later, when I was running Feisty, it somehow was rendered onto the desktop instead of the background image.
This behaviour makes the proprietary nvidia driver unusable. The free nv driver works correctly, but using it means to completely sacrifice any 3D acceleration. I noticed these things in every 1.0.9xxx version of nvidia's driver that i have tried, including the driver currently included in ubuntu's repository (1.0.9631+2.6.20.2-8.6). The 1.0.7xxx and 1.0.8xxx drivers worked flawlessly.
Painting random pixmaps from some X cache is also a serious security breach; showing a "screenshot" of evolution, with emails recently received by a different user running a different operating system installed in a different partition is clearly unacceptable.
I have added my xorg.conf, two screenshots, and a theora screencast teo give you an impression of this bug. On one of the screenshots, you can spot a distorted pixmap of the Alacarte menu editor, which i opened and closed some minutes an earlier. the title bar is clearly visible at the bottom of the image. |

I am confirming this bug because it seems similar enough to mine and I have gotten the same results. I too have the same problems even after installing the drivers from nvidia. I would like to note that this did not occur in feisty until one patch came out, then everything stopped working. I believe it was around the time when the 2.6.20-5 kernel was out. |

I changing the status back to unconfirmed because this was caused by a hardware error (at least for me). |

Just to rule something out, can you check that disabling powernowd as described in https://bugs.launchpad.net/ubuntu/+source/linux-restricted-modules-2.6.20/+bug/109643/comments/9 doesn't make any difference? |

Setting back to unconfirmed as reporter no longer has this hardware. With the original reporter gone I would recommend closing this bug... |
