Created attachment 510711 [details] photo With the nouveau driver on a geforce 6200 connected to a VGA LCD panel, the right edge of the screen's image is "cut off", as the attached photo demonstrates. This does not occur with the integrated intel graphics on that machine or with the proprietary nvidia drivers (however the nvidia drivers seem to butcher the fonts for some reason, as if it squeezed the image into place). This is not an issue of adjusting the LCD screen: - auto adjustment does not solve the problem - manual adjustment reveals that the input image is the one being cropped; changing the horizontal position on the monitor moves the image but it is still cut off.
To my knowledge this appears to be a hardware limitation (a mode's width/height must be a multiple of 8). Nouveau is programming the CRTC for 1360x768, while it is rendering to 1366x768 still, hence the chopped off bits :) I presume the NVIDIA binary driver works around this in some way or other, are you able to post a verbose Xorg.0.log from running it for me? ("startx -- -logverbose 999" should do it). If you're feeling really keen, you could also grab and install http://cgit.freedesktop.org/~currojerez/tvdump and run this while the NVIDIA binary driver is running. It'll capture the relevant setup and we can see what they did a bit better. Thanks!
I have been unable to "startx --logverbose 999", it would try to start, black screen then throw me back at the terminal (I had stopped X/gdm with "service prefdm stop" beforehand)... however, here is the register dump from tvdump.

This message is a notice that Fedora 15 is now at end of life. Fedora has stopped maintaining and issuing updates for Fedora 15. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At this time, all open bugs with a Fedora 'version' of '15' have been closed as WONTFIX. (Please note: Our normal process is to give advanced warning of this occurring, but we forgot to do that. A thousand apologies.) Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, feel free to reopen this bug and simply change the 'version' to a later Fedora version. Bug Reporter: Thank you for reporting this issue and we are sorry that we were unable to fix it before Fedora 15 reached end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged to click on "Clone This Bug" (top right of this page) and open it against that version of Fedora. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
