Created attachment 408959 [details] o/p xrandr -q, xvidtune (screenshot), lsmod and Xorg.0.log for various kernels Description of problem: After updating to 2.6.33.2-57.fc13.x86_64, the X screen is flickering. It is not noticeable always. But, especially when you go to certain websites etc, it becomes noticeable. It is also very much noticeable in the login screen of kdm and also during machine start-up and shut-down screens. However, it strains the eyes a lot. It mostly appears as horizontal flickering. But, while looking at the blank desktop it appeared as some sort of concentric waves. Version-Release number of selected component (if applicable): 2.6.33.2-57.fc13.x86_64 How reproducible: Always. Steps to Reproduce: 1. Start the machine 2. You will notice it when the machine boots-up 3. Open firefox and visit a site like http://meld.sourceforge.net/ and you will see the entire body of the page flickering Actual results: The screen flickers Expected results: The screen should not flicker Additional info: Please see the attachment. I could not see much difference between the command o/p taken with various kernels. However, it is very clear that the screen behaves well under 2.6.33.1-24.fc13.x86_64 & 2.6.33.2-41.fc13.x86_64. But, it flickers under 2.6.33.2-57.fc13.x86_64

Why there is no response on this bug? http://intellinuxgraphics.org/ has released new kernel. When will Fedora get the new driver in its kernel. Windows 7 has no screen flicker on my machine. but Fedora has. it is hurting my eyes!
sorry to pile on here. I've got the same flickering issue with F13 on a dell inspiron 1464. for what it's worth this does not happen on ubuntu (running 2.6.32.x). I have not tried downgrading my F13 install to the 2.6.32 kernel. happy to get more info if needed. kernel /vmlinuz-2.6.33.5-124.fc13.x86_64 ro root=/dev/mapper/vg_t150-lv_root rd_LVM_LV=vg_t150/lv_root rd_LVM_LV=vg_t150/lv_swap rd_NO_LUKS rd_NO_MD rd_NO_DM LANG=en_US.UTF-8 SYSFONT=latarcyrheb-sun16 KEYBOARDTYPE=pc KEYTABLE=us rhgb quiet [root@t150 xinit]# lspci | grep VGA 00:02.0 VGA compatible controller: Intel Corporation Core Processor Integrated Graphics Controller (rev 12) [root@t150 xinit]# modinfo video filename: /lib/modules/2.6.33.5-124.fc13.x86_64/kernel/drivers/acpi/video.ko license: GPL description: ACPI Video Driver author: Bruno Ducrot srcversion: FAF8A980798680EB6026B6B alias: acpi*:LNXVIDEO:* depends: output vermagic: 2.6.33.5-124.fc13.x86_64 SMP mod_unload parm: brightness_switch_enabled:bool parm: allow_duplicates:bool
Fresh Fedora 13 install last night, also did updates. I noticed an update to intel video drivers, which fixed the freezing problem when compiz was turned on. However, it hasn't fixed this screen flicker issue. # lspci | grep VGA 00:02.0 VGA compatible controller: Intel Corporation Core Processor Integrated Graphics Controller (rev 12) # modinfo video filename: /lib/modules/2.6.33.5-124.fc13.x86_64/kernel/drivers/acpi/video.ko license: GPL description: ACPI Video Driver author: Bruno Ducrot srcversion: FAF8A980798680EB6026B6B alias: acpi*:LNXVIDEO:* depends: output vermagic: 2.6.33.5-124.fc13.x86_64 SMP mod_unload parm: brightness_switch_enabled:bool parm: allow_duplicates:bool
Fresh install of FC13 with all the latest updates. I am having the same problem. Also acer 5740 with intel HD graphics. Is their no fix in 3 months?

I recently tried compiling a bunch of drivers from working kernel source against the new kernel and used them with latest kernel. Strangely even that did not fix the issue. I don't fully remember what all drivers I tried compiling that way. But, I looked at my lsmod info and compiled the whole set of folders which I felt are related to my video drivers. If someone is interested and thinks this will help, I can repeat this experiment and post the details here.
The same problem in my dell 1464 core i5 and 2.6.33.6-147.fc13.i686.PAE

But, it > flickers under 2.6.33.2-57.fc13.x86_64 2.6.33.2-42, -43, -46, -47, -49, -53 and -56 kernels are in koji, if someone wants to try to bisect this. Start with -47 and go from there: http://kojipkgs.fedoraproject.org/packages/kernel/2.6.33.2/ If -47 works, try the next one halfway between that and -57. If it fails go the other direction -- just keep splitting the difference until there are no kernels left between the working and broken one.
I tried 43,47,53 and 56 from the above location. Till 53 it was fine. 56 is having this issue (http://kojipkgs.fedoraproject.org/packages/kernel/2.6.33.2/56.fc13/x86_64/kernel-2.6.33.2-56.fc13.x86_64.rpm).
This is probably caused by the big drm-next update in -56. Here's what went in between -53 and -56 (the acpi-sleep patch would only affect things if someone did a suspend/resume cycle): * Mon Apr 19 2010 Adam Jackson <ajax> 2.6.33.2-56 - drm-intel-next.patch: 2.6.34 as of today, plus anholt's for-linus tree as of today, plus most of drm-intel-next except for the AGP/GTT split and a broken TV detect fix. Tested on 945GM, GM45, and gen5. - drm-intel-make-lvds-work.patch: Rebase to match. - drm-intel-acpi-populate-didl.patch: Drop, merged in -intel-next - drm-intel-gen5-dither.patch: Use better dither on gen5. * Mon Apr 19 2010 Matthew Garrett <mjg> - linux-2.6-acpi-sleep-live-sci-live.patch: Try harder to switch to ACPI mode * Mon Apr 19 2010 Adam Jackson <ajax> - linux-2.6-intel-iommu-igfx.patch: Disable IOMMU for GFX by default, just too broken. intel_iommu=igfx_on to turn it on. (Adel Gadllah) Also, can someone try 2.6.34.1-29 from koji and see if it's fixed there?
still flickering whit 2.6.34.1-29 from koji
Works with kernel 2.6.35-0.57.rc6.git5.fc15.i686.PAE from rawhide
2.6.35-1.fc14.x86_64 is working for me.
i installed 2.6.35-2.fc14.x86_64 just now. no flicker now. my eyes feel cool:) I can concentrate my coding work now. will wait for fc14.
Great, now how do we get this fixed in f13?
Confirmed that 2.6.35 fixes the issue (I'm on an Asus U50F). Chuck: just download the kernel source and compile it yourself. Piece of pie.
2.6.35 fixed it for me as well (dell inspiron 1464). thanks!
The cost to using 2.6.35 is that our system become unstable. my wireless connection can not reslove dns well. it often lost connection. How can fedora expands its market if it can only make fun for linux fan instead of normal user. The time we spend on it may cost much more than Microsoft windows license fee.
Hello, I'm facing the same problem. But I'm currently using ubuntu here. I want to change to fedora. But how can I fix this problem? How can I update/upgrade to this kernel? PS: I'm posting this with a anonymous acc (BugMeNot) because I don't like to register too much :)

Nobody from Fedora is claiming that 2.6.35.2 is ready for production use. (It's in the Fedora 14 alpha release.)
This message is a reminder that Fedora 13 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 13. 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 '13'. 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 13's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 13 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 please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. 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
Fedora 13 changed to end-of-life (EOL) status on 2011-06-25. Fedora 13 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. Thank you for reporting this bug and we are sorry it could not be fixed.
