Created attachment 694366 [details] dmesg after some screen corruption Description of problem: 1. After some time working with the system it starts to corrupt pieces of the screen. It happens mainly using LibreOffice and Firefox. If you close the session and start a new one it works fine ... for some time. 2. As you Resume after hibernation or Sleep you get a totally corrupted screen, the system hangs up and you have to reinitialize. I reported similar bugs on F16 (870358) and F17 (879554).

It's a regression fault as far as it worked fine until Kernel 3.4.11 on F16
I have just tested Kernel 3.7.7-201.fc18.i686 and using five minutes Firefox and LibreOffice Impress I got spots on the screen and I found with dmesg this error: nouveau [ PFIFO][0000:01:00.0] CACHE_ERROR - Ch 4/0 Mthd 0x0060 Data 0x8000000f It seems the same as before. Regards

Workaround is to disable display power management. Migration to xorg-x11-drv-nouveau-1.0.6-7.fc17.x86_64 seems (so far) to solve the issue.
replicated the steps but couldn't get the spots or a corrupted screen. What i did. 1. Sleep 2. Resume 3. Run libreoffice. #5 minutes wait. 4. No error. 5. Ran Firefox. #5 minutes wait. 6. Ran both firefox and libreoffice. #5 minutes wait. No error yet. I think what Frantisek Reznicek suggested should be working, migrate to xorg-x11-drv-nouveau-1.0.6-7.fc17.x86_64 Did i do anything wrong in replicating the process ?
I'm sorry but I can't try it again as far as I had to migrate to another distribution due to this persistent error. In my case and until F18, Kernel 3.7.7-201.fc18.i686, Hibernate and Resume was enough to replicate the corruption. Always and immediate. Just using Firefox or LibreOffice was not so fast. You had to spend some time, some activity, but no more than five minutes. Regards
This message is a reminder that Fedora 18 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 18. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '18'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 18's end of life. Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 18 is 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 change the 'version' to a later Fedora version prior to Fedora 18's end of life. 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.
Fedora 18 changed to end-of-life (EOL) status on 2014-01-14. Fedora 18 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed.
