Description of problem: When X is started the screen is often corruped with "dithered pixels". Grephics look rough around the edges and small fonts are unreadable. The proprietary nVidia driver from ATrpms does not suffer from this problem. The problem is much more bothersome when it happens on install as it requires a restart or text install. The same problem occurs under FC5 and FC6T1. System is a Lenovo 3000 N100 laptop. Version-Release number of selected component (if applicable): xorg-x11-drv-nv-1.2.0-3.fc6 How reproducible: Happens frequently, not always; but problem is always resolved by restarting X one or more times. Steps to Reproduce: 1. Start x from installer, command line, or runlevel 5. 2. 3. Actual results: Screen is often corrupded with dithered pixels, unreadable fonts. Expected results: Clean X display.

Please attach /var/log/Xorg.0.log from a run of X that displays the problem. Also, try adding the line Option "FPTweak" "-1" to xorg.conf under the line for Driver "nv".
Naturally, after seeing the problem consistently before reporting, I can't reproduce it now. Perhaps recent updates fixed it. Leaving FPTweak line commented out for now. If the problem does not recurr will close this bug.
Created attachment 134524 [details] /var/log/Xorg.0.log with problem
Have managed to replicate the pixel dithering problem and submitted the log file; however, I doubt it shows anything unique to the problem. I have discoverec that switching fromn X to a virtual console and back will "toggle" the problem more or less randomnly without any effect in the log. No such problems with the nVidia driver rebuilt from Axel Thimm's kmdl src.rpm.
Fedora Core 5 and Fedora Core 6 are, as we're sure you've noticed, no longer test releases. We're cleaning up the bug database and making sure important bug reports filed against these test releases don't get lost. It would be helpful if you could test this issue with a released version of Fedora or with the latest development / test release. Thanks for your help and for your patience. [This is a bulk message for all open FC5/FC6 test release bugs. I'm adding myself to the CC list for each bug, so I'll see any comments you make after this and do my best to make sure every issue gets proper attention.]
The issue is still present in current FC6 with updates. It is a minor annoyance with the work-around of switching to a virtual console and back, and is not present with the proprietary nvidia driver.
thanks.
Fedora Core 6 is no longer supported, could you please reproduce this with the updated version of the currently supported distribution (Fedora 7, 8, or Rawhide)? If this issue turns out to still be reproducible, please let us know in this bug report. If after a month's time we have not heard back from you, we will have to close this bug as CANTFIX. Setting status to NEEDINFO, and awaiting information from the reporter. [This is mass-filed message to all open Fedora Core 6 bugs related to Xorg or Gecko. If you see any other reason, why this bug shouldn't be closed, please, comment on it here.]
Since there are insufficient details provided in this report for us to investigate the issue further, and we have not received feedback to the information we have requested above, we will assume the problem was not reproducible, or has been fixed in one of the updates we have released for the reporter's distribution. Users who have experienced this problem are encouraged to upgrade to the latest update of their distribution, and if this issue turns out to still be reproducible in the latest update, please reopen this bug with additional information. Closing as INSUFFICIENT_DATA. {This is mass-closing of all obsolete bugs; if this bug was in your opinion closed by mistake, please, reopen it with additional information; thanks a lot and I am sorry for bothering you in such case.}
