Fedora :: Monitor Becomes Inactive (goes Blank) When Watching Video
Jul 18, 2011
I run LXDE with Openbox as WM on Fedora 15. When I watch videos with Totem or VLC, the monitor doesn't register any activity, and goes into power saving mode (goes blank) after a certain amount of time (about 10-15 mins). How can I prevent this from happening? (I just switched over to Fedora from Arch, using GDM and Openbox. I didn't have this problem on that installation, so it's probably not hardware related.)
So after I installed the ATI Radeon 3400 series video card in my machine, the Xserver cant start! after it loads, it takes me to the init 3. When I tried startx, the screens either go blank or doesnt let me.
I tried to install everything following this website: [url]
I wanted dual monitors but now I cant even get one. The xwindows doesnt appear.
Things I tried: 1. Deleted the xorg.conf and reconfigured (didnt work). 2. sax2 -r -m 0=versa (didnt work) 3. reconfigured the ATI radeon driver from init 3 (didnt work) 4. copy and paste the oold version of xorg.conf (didnt work) 5. tried to run set apt or dpkg-reconfigure command (commands not found) 6. tried xconfig and prompt the best I coudl (didnt work). 7. aticonfig commands (As shown in website) (also didnt work)
I have the live CD to run it from there but I dont know what to do once I get to the terminal.
Is there any way I can revert to previous configuration since the ATI driver gives me some problems? Like a restore function in windows?
How or what files I should change for the X-server to run properly (is there any other file than xorg.conf?....)
The monitors I have: 2009W Dell Monitor 1398 Dell Monitor (I wan to get the dual exntended monitor but it seems to gave me only the mirror image, thats why I tried to reconfigure the video card)
VideoCard: ATI HD Radeon Mobile 3400 Series
Computer: Dell Optiplex 680 (i believe) with SUSE 11.26 and x86_64 bit
My VLC player blocks screensaver while playing, but my monitor still turns off when watching for some time. I did a few searches, but I don't see any good keywords so I'm starting a new thread.
Problem is that with all kernel-xen x86_64 from current kernel-xen-2.6.18-194.26.1.el5.x86_64 back to kernel-xen-2.6.18-128.el5.x86_64 after kernel boots monitor goes blank and says "no video, going to power save".
Google finds similar problems and sugestions was to add "nomodeset". With this option monitor also blanks after kernel boot, but says "out of range". Other options to modify xorg.conf does not apply, becouse there is no X installed.
I try with multiple monitors, without success. This happens only with 64bit kernel-xen. All other 32 and 64 bit kernels and 32bit kernel-xen works fine, video is ok. This happens to 6 servers, all are same hardware, used as cluster. Installation with "linix text" allways is fine, video disappears after first reboot when standart kernel is booted. I also tryed with almost all possible "vga=xxxx" kernel options and none of them works.
I installed Xubuntu 10.04 on an old HP and I decided to swap the hard drive to an Old Dell Dimension 2300. Once I did that I logged in and continued to do stuff. I got a few Instant messages before I noticed I had no sound. I tryed to watch a video and I get the same result. I typed the following;
Previous Fedora releases allowed me to connect to my external monitor via an HDMI-DVI cable to use as my main monitor from my laptop. However, after I did a fresh install of Fedora 15, I have this problem that when I login to gnome 3, both laptop screen and external monitor go blank. I cannot ctrl-alt-f2 to go to terminal. I end up having to ssh from another machine and reboot. Each time, the reboot doesn't even work since I have to go and kill Xorg before it starts to reboot.plymouth and gdm seem to be fine and show up the external monitor. It is only when I login to gnome3 that I get the blank screens.
I have installed Fedora 15 64bit live with no apparent errors and I get to the "Welcome" where it says just a few more steps before I can start using Fedora after filling in the details hit the "Forward" button in the lower right hand corner. The problem is I can't see the forward button, its like I need to page down or something but everything I have tried isn't working. I then decided to use the Fedora 15 64bit DVD thinking a driver was missing or something and it is still the same issue. I am using a Thinkpad T61 laptop with an external monitor and the external monitor goes blank when it boots to the welcome screen, but I can scroll over to the external and see the mouse cursor on the external. It seems that if I could see the welcome screen on the external monitor that I might be able to see the "Forward" button. Both installs went without a hitch, the DVD install found my internet connection and downloaded a bunch of stuff and the DVD install took about two hours to complete, again with no errors reported. I hope I am not being daft here and missing something obvious.
After trying ubuntu for an year and suse for a week I finally decided to try out fedora 12. I have a problem with the video. This is what happened, I was watching ..... paused the video and then moved to other tabs finished some stuff and returned back to ..... tab and I noticed that the video is blank. There is some white screen which covered the video part of the page and rest of the page is visible. I don't have any idea why this has happened.
I have Kaffeine version 1.1 and KDE 4.4.4 release 2 installed on OpenSUSE 11.3. During watching video in Kaffeine the powersave will start and after 30seconds will switch my computer off. When I watch video in Xine I do not have this problem (screen saver timeout is set to 10 seconds). I have not found this option in xine-config.
I'm just getting started with Ubuntu 64-Bit. Basically, I have Totem Movie Player and VLC Media Player installed and every time I watch a movie in either one of them. If I tab out of them or minimize them, when I bring the media player back up the screen is black. The sound still works perfectly but I can't see the movie and I've tried several media players out and they all do the same thing. Basically I can't multitask or bring up anything else while I watch a movie or I have to restart the player because of the media screen going black.
I'm not sure if my computer specs will help but here they are: Ubuntu 10.04 Lucid 64-Bit Intel Xeon X3210 2.13GHz Quad 4GB DDR2-800 RAM ATI Radeon 4870 512MB Videocard
My system froze when watching a flash video and I had to do a hard reset. Now when I boot into ubuntu I can't open the software centre or the update manager. Is there a way to check what's wrong or a way to reinstall everything from terminal? Synpatic still opens and works.
I am running openSUSE 11.1 on a Pentium Dual Core 2.5 (E5200) Processor, 2GB RAM and an NVidia 8400GS PCI Express display card.When I intitially installed my system I also installed VLC media player, at that time it was version 1.0.1, Mplayer and SMplayer a few codecs for K3B, handbrake for DVD ripping etc. That was also the only time since my computer has been online, i have never updated it since. And it had no problems whatsoever. Among other things I use my system to watch DVD's. I watched many DVD's and video clips flawlessly.
Now all of a sudden when watching DVD's and video clips the DVD playback flickkers red (the color red). I am not sure what causes it and it is very irritating. It flickkers even more with video clips. With a DVD it dissappears after a while but as soon as you move your mouse pointer or click on the screen it starts to flickker red again.I thought it was my NVidia card that might be faulty, but I booted up from a Puppy linux live-cd and I played a DVD from there and it works 100%.
My system just freezes randomly. It happens about once a day, which is really often imho. It usually happens when I'm watching a video in fullscreen and it suddenly stops. I can't alt-tab or escape out of fullscreen, my mouse doesn't work and the keyboard is unresponsive. I'm forced to restart by pressing my computer's power button. This happens in both vlc and kmplayer and it also happened a few times when i was not watching a video. I was just on firefox, browsing the internet.
I'm new to Ubuntu but I installed Ubuntu 11.04 with no problems. I activated the recommended drivers for my laptop. My laptop is: Acer Aspire 7540G with ATI Mobility Radeon HD 4570 video card and AMD Athlon II X2 processor. So the problems comes very very often. I watch videos on fullscreen or I leave them playing in ...... While playin a video the laptop just freezes. Everything stops working. I think this problems comes up may be every 30-40 minutes of watching a movie. I'm not a fan of holding the shut down button for 10 seconds every 40 minutes so I'll be very grateful if someone helps. I've removed Syn to Vblank from the CompizConfig because otherwise Ubuntu runs really slow on my computer and the videos are playing very slow and with very bad quality. When i removed it everything began to run faster but now I've this problem with the freezing... Any ideas ?
i have for pc connect to my hdtv and sometimes it blinks alot.it like someone is changing the channel. it does it the most when i'm watch a video in movie player. i thought it was just movie player but it does it when vlc player too. oh and it does it too with the nvidia drive on way more.
i tried kde settings: disabled screen saver, disabled monitor power management. nothing worked. even i tried to find something in yast -- no luck. actually screen goes black after about 10 mins of inactivity which is annoying while watching in ex. videos. playing kaffeine is ok - i think it's because kaffeine makes "fake mouse movements". suse 11.3, linux 2.6.34.4-0.1-default x86_64, kde: 4.4.4 (kde 4.4.4) "release 2". adm athlon dual core 4450e (2.3ghz), 2 gb ram, geforce 9600 gso 512 with nvidia driver.
I have been trying out the new Slackware 13.37 and I have found that KDE will crash anytime I am watching a full screen video with Firefox 4 and attempt to adjust the audio levels using the keyboard buttons. If I use the mouse to adjust the audio level through the audio mixer gui, it seems to work fine. Both of my laptops ( a Gateway MP6954 and a Dell Inspiron 1520) are exhibiting this same problem. Both have the Adobe Flash Player version 10.2.159.1 installed.
When I try watching HD or avi files with totem the sound and video skips then equalizes on its own, when I try in vlc same thing but I play with the sound until video and sound sync but there is slowness in video.mplayer won't start. I installed the gmplayer front end and I just get that but no video or sound, video won't play.
From time to time system freezes with no particular motive but most often when watching you tube video in full screen mode. How to diagnose freeze, hang, blocking problems in debian jessie system amd 64 gnome 3?
Phenom 9500+ quad core, 3GB RAM, Nvidia 8800GT: 260.19.36 driver.Installed the latest Boxee for Linux. Got my remote setup. Everything works except when I open a video it opens in a tiny box in the upper left hand corner of my monitor.Is there any way to get Boxee videos to play full-screen?
I am doing a new install of i86_64 on a system with a wide 22" monitor. The initial screen displays fine but after selecting "new install" the monitor becomes alternating black and white horizontal bands. the cursor is visible and tracks the mouse. The monitor is an Acer with fixed 37kHz horiz x 60 Hz vert. I assume that the gui is using a fixed (and different ) set of frequencies and is not plug-n-play. I just finished an i386 32 bit installation on another machine which went without a hitch.
I recently upgraded from fc8. I am running two nvidia NVS 285 cards with four monitors and using nvidia driver 190.53-pkg1. I have one card up and running and can edit the config file and make to other two work I just can't get all four to work together.
I'm a newbie so apologies if there is a trivial answer to this.
I (maybe somewhat rashly) tried to connect my tv to my laptop (Dell Latitude D400) running Ubuntu 9.10.
I plugged in the cable, went to the System>Display menu, where it had detected the model and make of tv (Samsung 19" LCD) (I think the resolution was 1650 x 1050 or similar). I clicked the box to activate the second monitor with the "Virtual resolution" adjusted. It told me to log out then log back in.
I accordingly logged out but then couldn't log back in. It had evidently changed the resolution not only on the 2nd monitor but also on the laptop monitor. A box was visible on screen but completely illegible/unclear since the laptop monitor couldn't display that resolution.
After a few restarts and button pushes it is now restarting at a terminal (I enter my username/password at a command prompt on an otherwise blank screen rather than the graphical interface loading up).
Question: are there any commands that could change the resolution back to its original settings then restart the Ubuntu graphic interface? Some thing similar to the "load with last known good configuration settings" option in Windows maybe.
After the login screen, my laptop screen is active but the external LCD monitor hooked to my laptop goes blank which was active to that point.
Here are quite a few details which might help you in diagnosing the problem
alt + clt + f1 takes the monitor screen to command line but alt + clt + f7 fails to bring it back to GUI. The monitor just freezes!!

I have an Acer Aspire 5100 with AMD turion 64X2 and an ATI radion XPRESS 1100 graphics card.I recently installed suse 11.2 (clean install) without much trouble but I've always had some intermittent trouble were the screen would just go blank after boot up (before login screen) this did not happen always and never happened in safe mode or on XP on the same laptop, ergo software fail.Anyway, this morning I have a laptop with absolutely nothing on the screen from start to end. I also get a loud beep followed by two shorter beeps!If I let the boot up progress I can blindly find myself in normal Suse or in safemode or even in XP all without anything on screen
I just replaced my PSU and now my computer is not booting up. To make sure that my new psu is not causing the problem, I put my old one back in but it still doesn't boot up. My system powers on, motherboard led glows, the processor starts running and so does the graphics card. The monitor stays blank though. Nothing shows up on the monitor. Just a blank screen with the monitor led blinking. What could be the problem ? It was working fine before I replaced my psu.
