The nv driver is doing a different offset than the nvidia driver with the same config in other ways. This is a driver bug in X. This is not just a problem with nv driver - I have installed Fedora on other machines with different graphics card (e.g. Intel integrated graphics controller) and this problem has occurred. It would be solved by making the installer use a smaller percentage of the screen than 100%, thus allowing for any offsets/borders. It is not 100% clear what you are saying here, but I can make a few guesses. It sounds to me like you are describing that you are getting a virtual resolution (root window size) that is larger than the physical resolution (video mode) when in the installer. For example, your display might be in 640x480 physical resolution, but the root window is 1024x768 (hypothetically), resulting in part of the installer screen being off screen. In this case you would have a desktop that scrolls around when your mouse pointer reaches the sides of the physical display. Does this describe the problem you are seeing? If so, this is not an installer bug at all. It would most likely be that ddcprobe and/or the X server is unable to DDC probe your display. This can occur if you are using a non-DDC capable monitor, or if you are using a KVM switch. It can also occur if the "nv" driver does not fully support the specific nvidia chip on the card you have. THere are other reasons why this may not work also. The installer has a minimum size which is required. If your display can not be detected properly, then you will either get the scrolling virtual desktop, or you will have to perform a text mode installation. Setting status to "NEEDINFO", awaiting response to comment #3. No, it's not that. The problem is that on analogue monitors, the horizontal alignment of the picture produced by the nv driver is a couple of centimetres to the right of the equivalent picture produced by the closed-source nvidia drivers (on both Windows and Linux). This is presumably due to the timing of the signal (which can be adjusted by xvidtune) on analogue monitors; the problem does not occur on digital monitors. For long-term use, this problem can obviously be resolved either through xvidtune or by adjusting the controls on the monitor to re-align the picture. However, for the installer, my suggestion was to deliberately leave an unused border around the edge of the screen, so that the installer window would fit on the screen in its entirety without needing to adjust the alignment controls on the monitor. Since this bugzilla report was filed, there have been several major updates to the X Window System, which may resolve this issue. Users who have experienced this problem are encouraged to upgrade to the latest version of Fedora Core, which can be obtained from: http://fedora.redhat.com/download If this issue turns out to still be reproduceable in the latest version of Fedora Core, please file a bug report in the X.Org bugzilla located at http://bugs.freedesktop.org in the "xorg" component. Once you've filed your bug report to X.Org, if you paste the new bug URL here, Red Hat will continue to track the issue in the centralized X.Org bug tracker, and will review any bug fixes that become available for consideration in future updates.
