Description of problem:
I recently installed F11 and updated to latest. My screen will (seemingly randomly) go blank for a short while (0.5 to 1s) and then resume normally. This causes no disruption in my work and productivity other than the fact that I don't have my monitor available to me for ~1s. This happens at unpredictable times. About once every other day. I am using the r128 driver. lspci labels my device as "01:00.0 VGA compatible controller: ATI Technologies Inc Rage 128 Pro Ultra TF".
The bug occurs at inconsistent intervals and is unpredictable however occurs several times a week.
$ rpm -qa xorg-*-r128
This bug appears to have been reported against 'rawhide' during the Fedora 11 development cycle.
Changing version to '11'.
More information and reason for this action is here:
I have the exact same problem, different driver (using the radeonhd driver).
I doubt it's the driver, I suspect gnome power manager.
I have this same problem, usually it occurs about 1-2 seconds after the display wakes up after having been asleep. I'm using the intel driver, and this was happening on fedora 10 also.
I experienced the 1 second flash of the display with Fedora 11 as well. I never saw this with 10. kmod-nvidia-185.14 from rpmfusion. GeForce 6800 Ultra.
I wonder if it is related to:
I fully agree with Thomas's assessment.
I have the same problem too, using F10 and the "ati" driver, which inturn loads the radeon module for my "ATI Radeon HD 3600 XT" (ChipID = 0x9598).
I have a Dell 30" LCD on an nVidia 7800gtx which randomly goes to sleep while I am actively using the system. If I don't touch the mouse it will stay asleep - and moving the mouse wakes it up and back to normal.
Same problem with my two F11 64 bit machines. Happens the same with or without the latest nvidia driver in use. Card in both is nvidia gforce 7200. For me it looks a lot like when the screensaver or the power manager starts.
Possible dupe of Bug 500377 ?
Fedora 11, intel driver. If you can tell me how to catch any useful data on this, I'll be glad to try.

X server log after screen blanking
I've seen almost 20kB of references to "Calling BlankCRTC" and related messages at the end of my (attached) Xorg.0.log. The screen blanking has only occurred about 3 or 4 times. Blanking started to occur after upgrade to F11.
Seconding comment #4, looks like a dup of https://bugzilla.redhat.com/show_bug.cgi?id=459323
As a workaround I've turned off the screen saver on idle, and since then have not had the random blanking again.

I meant to say comment #8, dup of https://bugzilla.redhat.com/show_bug.cgi?id=500377
If everyone is in agreement, I think this bug is a dupe of bug 499061.
Bug 499061 specifically mentions that, despite settings, blanking occurs after two minutes of *idle* time - whereas I am experiencing screen blanking even right in the midst of keyboard/mouse use.
Chris, it seems more random than a set amount of time. I've seen it without using keyboard+mouse (before my screensaver timeout) and I've seen it while typing and moving the mouse. The symptoms of this bug, bug 500377, and bug 499061 are all nearly exactly the same. I don't think idle time is a factor.
I have the same problem, with: nehalem box with nvidia, lenovo x200 with intel graphics and acer laptop with nvidia.
Have no idea what triggers the blanking, it can happen during the activity or when hardware is inactive. :( It could be dupe either 500377 or 499061.
and seems all of the mentioned bugs here and this one are dupes of bug 501534.
oops, I meant bug 501601 ...
Same problems here, totally random and unprovoked screen blanking on an x86 FC11 desktop with NVidia chips and an x86_64 FC11 laptop with Intel graphics. My guess is gdm, not power management as it happens with or without power management running.

Even though you have gnome-power-manager off it could be DeviceKit using DPMS on your monitor to turn it off, couldn't it? I'm still thinking this is a dupe of bug 499061.
After setting the display sleep timeout to "Never" in gpm, I haven't seen my screen blank. It's been two weeks since I've changed that setting and several reboots. Try setting your display sleep to "Never."
I'll concede it might be gpm. Although my setting was the default 30 minutes, it happened at random times, with activity. I have set sleep to never...we'll see how it goes...
I also have the same issue, running F11 x86_64 and using Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller rev 12. I've set my display sleep to never and will see if it reoccurs.
Same problem here:
Linux hostname 18.104.22.168-217.2.3.fc11.x86_64 #1 SMP Wed Jul 29 16:02:42 EDT 2009 x86_64 x86_64 x86_64 GNU/Linux
Dell Precision WorkStation T5400 with dual 20" LCDs running @ 1600x1200.
and compiz enabled:
Same error happens on my desktop pc (HP Pavillion a6228.ac - nvidia) and one of my laptops IBM T43.
I have the same problem with the Intel i915 driver. Because I use my laptop for presentations it can be disturbing. If I move my mouse the screen comes back.
(In reply to comment #25)
Additionally I noticed that the screen doesn't go completely black but dims for something like 95%.
The last time it happened the screen didn't came back until I changed the screen lightness.
I observe the same since I installed F11 on my Lenovo T61.
00:02.0 VGA compatible controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (rev 0c)
My system now also randomly suspends :(
I do have updated my system yesterday with all 50 available updates. No available updates today.
Since this bugzilla report was filed, there have been several major updates in various components of the Xorg system, which may have resolved this issue. Users who have experienced this problem are encouraged to upgrade their system to the latest version of their packages. For packages from updates-testing repository you can use command
yum upgrade --enablerepo='*-updates-testing'
Alternatively, you can also try to test whether this bug is reproducible with the upcoming Fedora 12 distribution by downloading LiveMedia of F12 Beta available at http://alt.fedoraproject.org/pub/alt/nightly-composes/ . By using that you get all the latest packages without need to install anything on your computer. For more information on using LiveMedia take a look at https://fedoraproject.org/wiki/FedoraLiveCD .
Please, if you experience this problem on the up-to-date system, let us now in the comment for this bug, or whether the upgraded system works for you.
If you won't be able to reply in one month, I will have to close this bug as INSUFFICIENT_DATA. Thank you.
[This is a bulk message for all open Fedora Rawhide Xorg-related 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.]
I've encountered this issue quite frequently in the past, but I don't seem to recall seeing it recently (not for a few weeks at the very least). I'm on an (almost) up-to-date F11 install (Intel graphics) with the testing repository enabled.
My apologies for the vague time frame - I really need to remember to write this stuff down somewhere. :P
My screen still randomly goes blank. I can restore it by increasing the screen brightness with one time pressing Fn + cursor-up.
My system is up-to-date with X11 patches.
Could you please reply to the previous question? If you won't reply in one month, I will have to close this bug as INSUFFICIENT_DATA. Thank you.
[Note please, that this is machine generated comment for large amount of bugs; due to some technical issues, it is possible we've missed some of the responses -- it is happens, please, just a make a comment about that; that we will see. Thank you]
Works for me for months.
No issues here for months either. F12 32 / intel / KMS enabled.
I couldn't take all the deadlocks in X (an infinite loop problem of some sort in another bug) anymore so I switched to the vesa driver for a few months. Trying the intel driver for the last two weeks though has been flawless. Hurrah.
My system still has the problem. As I describe in my comment #31. I'm running an updated F11 system. I'm not planning to upgrade to F12 (yet). What can I do to help solve this problem?
This message is a reminder that Fedora 11 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 11. 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 '11'.
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 11'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 11 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:
Fedora 11 changed to end-of-life (EOL) status on 2010-06-25. Fedora 11 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.
I no longer experience this issue. Removing NEEDINFO.
