Fedora Hardware :: Monitor Sleep During Rhgb Since 2.6.35.9-64
Dec 23, 2010
I'm not sure, but I think this is hardware. Anyway, I have two different boxen running FC14. One has a Nvidia 9800, the other a Nvidia NV96. The former I use as a desktop, the latter a server. I've let the server go with whatever the system autodetects for video, but the desktop I've played with a ton: nouveau, nvidia, etc.
Anyway, since I upgraded both to 2.6.35.9-64, both go to sleep at some point during rhgb. I can't find anything in boot.log, messages, or what have you to try. This happens even if I go to runlevel 3, so unless I'm misunderstanding the boot sequence, this is way before X starts.
Now, just upgraded to 2.6.35.10-72 tonight, and the behavior slightly changed. Before, it would show the rhgb loading screen for a few, but then the monitor would sleep before it completed. As of this kernel, it just goes to sleep right away.
The only quirky thing I can think is that I'm running DVI out into a KVM. I have been making sure to have the machine as the active video when it boots, so it should still be able to feed EDID info to the machine, but I did notice when trying to track down nouveau/nvidia problems on the desktop that X was having trouble reading my EDID all the sudden.
I'm assuming there's some automagic default now that's putting my monitor out of range. The only way I've been able to keep the desktop running is to not have the nvidia driver installed, but also not have a driver type specified in xorg.conf. If I do that *and* specify a modelines, I can boot with rhgb off at runlevel 3, then manually start X. From the Xorg.0.log, it appears to be falling back to vesa, which is the only thing that works.
How can I debug this? If the monitor sleeps but there are no messages in boot.log, messages, or Xorg.0.log, how can I even figure out what rhgb is doing?

I have an odd problem since preupgrading from Fedora 12 to Fedora 14.
My power management settings are set to never put the monitor to sleep, yet after a certain amount of time, lo and behold, the Fedora box has gone blank and I have to enter my user information and password to get back to my gnome session.
In the power management preferences I have "never" selected for both putting the computer or display to sleep.
In the screensaver preferences "Lock Screen After" is *not* checked. (And if I click "advanced" I also note that "Power Management Enabled" is also *not* checked).
I'd just as soon not have to "log on" to this machine every time I'm away from it for a while.

I just upgraded a F9 to F11 using the network install. After the successful install message, I rebooted to find the boot stuck on a grub prompt. After determining that somehow grub had not been installed properly, I used the rescue mode to re-install grub. When I then rebooted, I saw a blank (black) screen during the rhgb sequence, with just the multicolor progress bar moving from left to right. As the bar reached the right side, the standard F11 login screen appeared. The system is an old Omnibook 8000 laptop. Here is my grub.conf
Code:

I have Ubuntu 10.04, and I have my power settings set so that my display is never supposed to go to sleep, yet it still does after 10 minutes of being idle. Has anyone else had this issue?

I am running Ubuntu 9.10 on my desktop and everynow and then I get this annoying problem. If I walk away for a bit, just upstairs to use the bathroom, sometimes when I come back the monitor is off and the power light is blinking. You know, like what monitors usually do when they are still powered on but the screensaver is done playing. However, this happens to me well before the 10 minutes that the screensaver is supposed to end.
It does not always happen, and I can't really isolate what may be causing it, as I never take a note of what I'm doing when I go pee. HOwever, I rarely do anything other that run VLC, Chrome, Firefox, or OpenOffice Writer.
The problem is that the screen won't wake up. Moving the mouse does nothing. Jamming some keys does nothing. Trying to go to text terminal does nothing. I have to either REISUB or hold down the power button on the tower.

I am trying to install Ubuntu 10.04 on my PC using NVIDIA GeForce 9150LE graphics and HP w2207h monitor. After using the Wubi installer and rebooting my computer, i select the ubuntu boot menu option and it says it is preparing to continue with the installation. after a countdown before it begins, my monitor goes to sleep. i used an eMachine monitor that i used in a previous installation of 9.10 that worked fine and reached the exact same problem. When booting from a live CD and selecting try without installing the screen comes up with a blinking underscore, and both monitors went to sleep. I believe its a problem with the graphics chip, but i dont know how to fix it.

I just recently got my old box back and now I'm running 10.4. I've had some minor issues that I have got through but now there is one which seems to really be frustrating me. At any random time my monitor may go black as if it is in sleep mode. The problem is when it does this, no mouse movement or keystroke will wake the thing up. So I am forced to press the power button. When I press the power button the Ubuntu logo pops up on the screen as if it magically woke up but it is too late because now the computer is shutting down... When I go to System>Preferences>Screensaver I get to the options for the screensaver and I have about 2 seconds before that triggers the screen going black.
I can't even start until I know that my screen won't shut off at any random moment!

I can't get debian 5.0.4 i386 to load I can get as far as root for crash repair during boot-up but much further than that and my monitor turns off. Ubuntu 8.04.4 live cd (kernel is 2.6.24 i believe) works but says I have to enter noapic in the boot string. APIC is on and greyed out i.e. not accessible in BIOS --- might be non-compliant Only thing I can think of is to add acpi=off in GRUB entry but the change doesn't seem to work or take effect. I added it to the relevant entries in menu.lst in grub and it still didn't take effect. Grub must be getting its config info somewhere else...

Running openSuSE 11.3 w/ a KDE 4.x desktop. Every time I'm using KTorrent, when I come back into the office and "wake" the monitor, I find KTorrent has crashed and I have to restart it. So I'm guessing that KTorrent is crashing either when my monitor goes to sleep mode or when I'm waking it up. I've tried changing some settings but when the system is running, I cannot seem to access the monitor control panel. Pressing the menu button on the side of the monitor does not bring up the monitor menu. There used to be an easily noticed "Desktop Settings" in KDE 3 but I'm not finding the equivalent in KDE 4. How to keep this Samsung SyncMaster 997DF 19" CRT from going into sleep mode?

Whenever I boot into ubuntu 10.04, my monitor just automatically goes into sleep mode. As soon as I select to boot into ubuntu, the monitor just sleeps. There's no getting out of it. Booting into windows works fine though, so the problem has to be ubuntu.

I've been using Ubuntu for about a month now, gotta say I'm loving it. I've been spending more time in Ubuntu than W7 now. I've been trying to get Steam to work with Ubuntu without the whole thing exploding on me. I've got WINE and winetricks already pretty much set up, and Steam works flawlessly. The problem appears when I try to launch Team Fortress 2. The monitor instantly goes to sleep, but if I wait a few seconds, I can hear the in-game music, which means that the game is loading correctly.
I'm using the 10.04 LTS release, Wine 1.1.42. Kernel version 2.6.32-22-generic. My graphics card is a Radeon HD 4850, running Catalyst 10.5.

infact im kinda of a "pre-life" Ubuntu user I have burned a CD-R disk with the ISO image of Ubuntu with infrarecord however... When Insert the disk and boot a screen pops up and I press enter then the language thing comes up and I select english but here is where the problem is, Its seems that for only a few seconds I can control my keyboard then it stops working...So everytime I try to click "try Ubuntu without install" I cant and it just sits there
after it sits for maybe ten seconds it looks like it is rebooting but then it says "Monitor going to sleep." and if I try to turn it back on its just a black screen. Also if I like Ubuntu (which I probably will) Im going to run a DBAN and install it from scratch and I dont really want any problems :/

My monitor falls to sleep when I get to the Grub Menu and choose "Ubuntu". It will get to the purple-ish loading screen to a minute before the monitor falls asleep. I am using 10.10, and this is my first experience with Linux. As much details as I can think of: I recently installed Ubuntu 10.10 after playing with it on a live CD. I chose to install it alongside Windows 7. The install was quick and smooth, and booted up as it should. When I get to the GRUB menu, I had more choices than I thought I would (I figured I could nix them later.)
These options were:
Ubuntu Linux
Ubuntu Linux (recovery mode)
Memory Check
different Memory Check
Windows 7
I chose windows 7, to make sure ol' semi-reliable, slow, and resource hogging OS worked. As expected, it ran through some stuff white-text-black-screen stuff to make sure all it's files were there (probably due to the fact I had to give some of my hard drive space to ubuntu). As far as I could tell, this did not modify any files, and it checked out with windows. I restarted using windows at this point....

Ubuntu 10.04
Under Preferences > Power Management I have changed the settings to never put the computer to sleep and never to put the display to sleep.
My display still goes to sleep and I am prompted for my password when I leave the computer unattended.
I would like to be able to hit the "Lock Screen" app I added to the top panel to lock my screen, but otherwise I would like it to just stay on.

You know that glitch where your monitor doesn't come back after switching off for power saving? That's gotten WAY worse since switching to Lucid. It used to happen every other day or so, now it happens 2-3 times a day. Songbird used to keep it from switching off on Karmic, but Songbird doesn't work on Lucid so that's out the window.
Also: as similar error happened when restarting after the glitch happened this latest time. Ubuntu started running its routine disk check and I hit C to skip it. The screen went down like it does in the Monitor Sleep glitch. I reset again, it did it again. Eventually, I just let it do the check. This has NEVER happened before.

I'm running a fresh 10.04 x86-64 on a thinkpad w500, using the default video driver. The monitor shuts off randomly, sometimes while I'm using it and requires me to trigger sleep mode and waking up to bring back the screen. When it shuts off, everything else seems to be running. (i.e. its not going to sleep) I've turned off screensaver, sleep, hibernation and installed the Caffeine util to no avail.

I am unable to install fedora 10 (both Live_CD and DVD) as the screen freezes at the Login page in LIVE_CD and in the welcome page in the DVD installation. Anyway i have narrowed down the issue by goin via the forum. Issue is with the graphics card only. I have tried the following steps to get around this issue,try removing "rhgb" from the bootline - not worked xdriver=vesa - Worked, i got via the Login page in Live_CD but the desktop is not completely visible and its freezes. vga=ask - not worked as i dont know which option to choose try removing "rhgb" from the bootline I am using 845GV motherboard, onboard Graphics card.

yum install rhgb
It installed rhgb and vte. I added 'rhgb' to the line in my /boot/grub/menu.lst :

openSUSE 11.3 64-bit fully updated, running the latest K3B, 2.0.1. from the Packman repos with the codecs installed. Sometimes it starts up and runs fine, others the splash and then nothing. And again other times it will start and never show up until I reboot and then there it is. When I go to system monitor it will show under CPU% "disk sleep" if that helps. FWIW I have similar issues with Nero 4. I've added myself to the cd rom group and all of that.

I have recently switched to Ubuntu (10.04) after running my system on Centos for years. This mostly due to much quicker startup times. I have a software that runs as a public presentation software on a public "bigscreen" so my Ubuntu runs like a "kiosk" pc that's always on. When i switched to Ubuntu everything worked lika a charm besides the fact that the screen falls in to "sleep"/"powersave" or something.
I think that i have tried everything to prevent this. I use Gnome and i have set all the powersavings features to off. Ive tried turning acpi off and i also turn dpms off at login. Nothing seems to kill the "screen powersaving" feature. As a desperate act i tried to use a software called Coffeine, this software should prevent powersavings. I added Coffeine to autostart to activate for 48h, I need the screen to atleast stay on for 24h.. Does anyone have an ide what cuses this? Dont really want to go back to Centos now... My system basicly looks like this:

This morning I woke up and while my computer was turned on, I couldn't wake my monitor up from "sleep". So I turned off the computer and turned it back on. I noticed that the normal boot screen (which usually shows a monster truck from Abit) was pretty severely distorted.Basically all output to the screen is so distorted visually that I can't tell what's going on. I've attached two images that I took below:
The first image is at the very beginning of the boot (perhaps when the monster truck should normally show <- sometimes it shows and sometimes it is just too distorted to tell anything). The second image is after it's been on for about a minute, and you can see a little text box giving me some sort of warning (which I of course can't read). I can click "OK" or something along those lines by using they keyboard though and progress to a new warning box, but again, can't read what they say. How can I figure out what the problem is?s it definitely a videocard thing, or could this be caused by anything? I don't know if it's a software problem (running Ubuntu 10.04), or if something went wrong with my hardware overnight.

I am facing problem with the fresh installation of Fedora 11. (I have moved from Fedora 9). When I try to view videos on ..... or use the Cheese Webcam Booth, I get blurred lines on the screen and I am unable to see any video or pic.
Also I noticed that the when i go to System > Preferences>Display, it shows me UNKOWN MONIOR.
However, if I got to System>Administration>Display and enter the su password, it shows me correct monitor and the graphics driver.
I am not sure if my original is related to the Unknown Monitor.

My Monitor is LG 700E and Graphics card is from intel. as I am not able watch any video.

I am having problems getting my external monitor to work. When I plug in the monitor, both the laptop screen and the external monitor go black. When I unplug the monitor, the laptop screen works again.
When I startup with the external monitor plugged in, neither screen works or teh computer hangs or something.
I have had the external monitor going on a couple of occasions. I did manage to configure my monitors through System Settings > Display. I turned off the laptop monitor as I just want to use the external. But after rebooting, things didn't work.
I have a Thinkpad E420, Fedora 15

My software and hardware information are as follows. I have Fedora 12 and KDE 4.4.5 installed on a Dell Vostro 1500 laptop. I believe it's a 64 bit processor; it's an Intel Core 2 Duo CPU. The external monitor is a Dell as well.
My problem is that my system does not seem to be detecting an external monitor that I have connected. Everything else is working just fine; however, I would like to have the option of attaching an external monitor. When I plug the external monitor into the laptop, the external monitor remains black and appears to be in power save mode. The results of xrandr -q (with or without the external monitor attached: it doesn't appear to change) are as follows.
Code:
How can I get my laptop to recognize that the external monitor is even connected? Let me know if I can be more specific or provide additional details.

I just upgrade to F14 from F10 on a dual montor setup. Firefox behaives differently on F14 than on F10.
On F10 it followed the mouse pointer's location and show up on the correct monitor
When maximized at close, it is always displayed on the left monitor. When not maximized at close it will open on the monitor where the mouse pointer is located.
About minimize/maximize Firefoxe before closing and it seems to work in some case, but not for me.

I had this problem at first in Fedora 14 KDE. When I try to put it to sleep or hibernate it will go to black screen and then just turn back up. And now on my other computer which runs on Fedora 13. After KDE 4.5.2 update it does the same thing. I think it is same problem but I can't be sure.
