I get an unusable screen for desktop. The screen flickers, there are horizontal stripes running across the screen, screen occasionally goes blank, screen is shifted to the left and wraps around, screen would sometimes corrupt, resolution selected is not the native resolution of the monitor. Mouse co-ordinates also seem offset, I have to click a little above a button to make it click. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1.Boot the live cd. Actual results: Unusable screen. Expected results: Usable desktop.

Do things improve if you add nouveau.tv_disable=1 to your kernel boot options? This is, assuming you don't actually have a TV connected?
Things that improved after adding nouveau.tv_disable=1 No more horizontal stripes. Didn't notice any screen corruption. Slightly less flickering. Things that did not improve. Flickering is less but still noticeable. Screen occasionally goes blank and comes back. Screen is offset to left and wraps around. Mouse co-ordinates are offset.
Resolution selected is not the native resolution of the LCD either. I could not find system-config-display to change the resolution.
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 It is Fedora's policy to close all bug reports from releases that are no longer maintained.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
