OpenSUSE Hardware :: Force X To Output Video Signal
Jan 25, 2010
I have a new cluster of four OpenSuSE servers serving VM's for a development lab. I have been fighting the good Linux/OpenSuSE fight against established Windows environment and I am embarrassed by certain hardware behavior in X.The four machines are in a cluster with an inexpensive TrendNet TK-407 KVM. The Linux Boxes are Dell T3500's with NVidia Quadro NVS290. I am not running the NVidia proprietary driver.
The behavior is that X keeps placing the display in sleep/powersave mode. If I boot the machine everything works until X takes over upon which point it decides that the display is not there and places it into standby.I don't care whether the KVM may or may not be responding correctly to some monitor protocol, and neither do I care to know or learn about the various DPMS or monitor protocols. The important thing here is that Windows experiences no such behavior. The solution I seek is to configure X to force the signal out of the card, disregarding any DPMS or other protocols.

Is there a way VLC to use vdpau as video output? Mplayer and Gnomemplayer can use it and the video playback uses as little as 2-4 % CPU power even on 1080p movies. Xorg and Kwin continue to use pretty much CPU power in video playback process , I suppose there is no way to limit them or there is ?
Open Suse 11.4 86x64, KDE4-4.5.6, NVidia 275.xxx.xxx

[code]...
you can find a cutout of an output generated by "iwlist s" command for a cell. Does anybody know what Quality, Signal level and Noise level mean? What is the definition of them? I searched for it and could not find good information on it. What do these Extra:*** fields for? What does it show in the example above? How were those values computed?

On an Asrock ION 330HT-BD box Im running Ubuntu 9.10 (2.6.31-17-generic) with the nVidia driver 185.18.36. The Asrock box uses the nVidia ION chip and the nVidia driver appears to be working without any problems.
My problem is, that I what to use the box as a MythTV frontend with an (old) SD Plasma screen as display, which have a native resolution of 852 x 480 and I cant get the box to output a 852 x 480 signal. The Plasma is connected with a HDMI -> DVI cable. No matter what settings I have tried in the /etc/X11/xorg.conf file, the box keeps outputting a 1024 x 768 (or higher) signal
Questions:
1) Is the nVidia ION chip capable of outputting a 852 x 480 signal?
2) If Yes to above, how do I configure my xorg.conf file?

A friend of mine recently broke his laptop's screen. He knew I wanted to setup a small personal server so he gave it to me. I used an old monitor and wiped the HDD and installed Ubuntu. At the end I chose to upgrade the freshly installed OS. When I rebooted the computer after upgrading I couldn't get any images on the monitor. I tried to unplug/plug it several times but it doesn't work. I keep getting the "No signal" message on the screen.
Is there a way for me to somehow force the computer to use the secondary display? And if not is it possible to install and configure all the packages to run a VNC server on it without seeing anything?

When I run a script with nohup, the output is forced to the out.log file by default; is there a way to force the output to the screen instead of the file? I need to be able to see when my script gives me a "process started" message, and I don't want to clog up the system with log files.

I'm having trouble getting 1080p out my xfx 9800gt that has an onboard hdmi socket. No doubt my HDTV is 1080p (panasonic TH-427PZ70B a few years old now), and it will do and has run at 1080p 60hz.
It auto detects the display as simply panasonic-tv and outputs at 1080i. As I've been running mythtv with tv tuners this actually worked quite well as dvb-t is interlaced anyway and most ofthe HD video files I play are 720p. However I would like to run it at 1080p for all the usual reasons- especially as I have some 1080p files I'd like to enjoy in all their glory!!
This doesn't seem to be ubuntu specific as mandriva behaves the same, and makes no difference if I use the open source (default with 9.10), the official nvidia package or as I've just tried 10.04 with default and nvidia.
I've searched around for nvidia hdmi 1080p etc but can't seem to dig up anything useful. Surely I should be able to force the graphics card to output standard 1080p 60hz?
Should I be able to do this through xrandr by setting a modeline or in xorg.conf or nvidia control pannel!?

I run a number of Ubuntu 9.10 boxes attached to multiple daisy-chained KVMs. None of the PCs are using any GUIs - they all run in console mode. I often reboot them remotely via an SSH session, etc. If a monitor isn't actually active on the PC when it reboots, Grub2 uses a low-res video mode, despite having a higher-res video mode set correctly in Grub2's configuration. If I reboot WHILE THE MONITOR is attached to the Ubuntu PC via the KVM, the video mode is set correctly as configured in Grub2's config files. If I reboot WITH NO MONITOR attached, the video mode is ignored and I'm stuck in a low-res mode next time I attach to the PC via the KVM. How can I force Grub2 to honor the configured graphics setting, despite not having a monitor present at the time it boots?

I just upgraded from Ubuntu 9.04 to 9.10 today, and went to watch a movie on my hard drive. I typically do this with an S-Video cord on my TV. In Ubuntu 9.04 I did so simply by plugging in the S-Video cord, then pressing FN+F4 on my keyboard. Worked like a charm.
After the upgrade the same key combination just changes my resolution setting.

This morning, I ran yum update and discovered it was an upgrade from 5.3 to 5.4. Nice, but.... The upgrade went well, no errors, did a reboot to reset everything and now no video output. Good thing I did full system disk backup prior to the upgrade. I am wondering if anyone else has this problem?
I will attempt to boot from a CD/DVD but just thought I would check here first.

I have an OggVorbis video file that only plays the audio on Centos 5.5 using SMPlayer, and mplayer from the CLI. This video works OK if I boot into Fedora 12, where I created it with recordmydesktop. the xvinfo output for F12 and CentOS 5.5 is the same:

On my pc, video playback is not as it should be. Somehow, not all video frames are displayed. In smplayer, I have video output set to x11 (slow). If I set it to anything else, it's worse. How do I know exacly what video output to choose ? Is video output determined by the video card ? My video card is ATi Radeon 9200 SE. What video output should I set in smplayer ?

Im trying to be able to output video to my tv with a low end atom cpu box(link below) running debian lenny. I realize it wont likely be true HD video. I also realize I wont be getting surround sound. My tv is a little bit older so it doesnt have a monitor input or I would have tried that. It does have HDMI and component though and i have a DVI to hdmi adapter and audio cables that will work once I have a video out solution. It does have a PCIE expansion bay but the power supply is only like 150w so i dont know that Ill be able to use a regular video card. I had considered some sort of usb output but dont know if any of that will work on linux. Any suggestions? Im pretty novice with the whole computer on my tv area and dont have alot of money to build a whole new system or i would just do that.

Excuse me if this is in the wrong place, I am new to the forum and Debian.
Today, while installing Ubuntu, I had a strange issue with my laptop in which after installation, I heard startup sounds and had no video display. After hours of frustration and about 7 install disks, I plugged my laptop into another monitor, and low and behold, it appears both of my desktops are on the external monitor. After trying to solve this issue, I decided to give the Debian Gnome live CD a try, but I now have the same issue.

I can't seem to figure out how to get the S-Video output working on my T41, and most of the info that I seem to be finding is for older versions before xrandr so files and settings don't seem to match.
I know that it's not a hardware/cable problem because this exact setup works fine under windows (even though there i'm working with a hacked video driver setup since one doesn't exist for any of the "modern" versions of windows, ati radeon 7500 (mobile))

Hardware: HP dv3505ea laptop
Ubuntu: 10.04 LTS
uname -a: Linux adventure 2.6.32-28-generic #55-Ubuntu SMP Mon Jan 10 23:42:43 UTC 2011 x86_64 GNU/Linux
HDTV: Panasonic TX-L37D28BSA
I'm having trouble getting any output from my laptop's HDMI socket. I've had a search and can only find sound problems, mine is no visible output whatsoever.
Let me describe the setup: Laptop has a HDMI socket which I have never used before, HDTV has 4 HDMI inputs, I just bought a HDMI cable to connect the two to try it.
After connection I go to System->Preferences->Monitors and the TV is detected fine with the correct description and offers me 3 different resolutions. xrandr also works and gives me the same thing:
Code:
However none of the options display ANYTHING on the TV. The screen remains black, not even a flicker.
I have connected the laptop to the TV before using an analogue VGA (monitor) cable which worked in the same way with no problems.
Could this be an encryption/DRM/DVI problem? I have suspicions about the cable too because it is new and I haven't seen it work, but it wouldn't detect the correct TV description and resolutions would it? It was sold as an XBOX360/PS3 HDMI cable, is there a difference? It looks like a standard HDMI male-male cable.
Other things I've tried:
Log off and log back on to restart the X server
reboot
Some more stuff:

I was experimenting with transcoding video with ffmpeg. using the command
Code:
ffmpeg -i moviename.avi moviename.mkv
outputs the .avi into .mkv, but the output quality is very, very bad, while the original is dvd-quality.

Fairly new to debian and linux and general. I have an install of debian wheezy (to run LinuxCNC). I went in the graphical interface to the 'monitor' section and changed the screen resolution. I had two monitors, one labeled monitor and another (I think) Lenovo Monitor.
There was a check box in the screen monitor window that said something like, "Don't use this display." I figured it might turn off the lenovo and default to the generic monitor listed. I clicked it and my monitor turned OFF!! I tried another monitor (Dell in this case) and same thing, no video output.
I asked on the LinuxCNC forum and googled, but I just dont' seem to be able to figure out what or how to get to the solution.
I have been able to Ctrl-Alt-F1 to open a terminal. But, I can't find any the right files and found that the xrandr command 'should' work, but doesn't.
Whenever I issued the xrandr command (other than man xrandr), I get "Can't Open Display"
I did find two outputs VGA1 and LVDS1 in this file /var/log/Xorg.0.log and this coincides with what I saw in the monitor window. These are the 'output' types and if the xrandr command worked I'd issue something like : xrandr --ouptut LVDS1 --auto
I read about xorg.conf, but I could not find any xorg.conf files in the etc/X11 folder. In some of the info I found, the xorg.conf was replaced in this or a recent version of Debian by something else and confuses me.
One person had a similar issue and he got to this directory: $HOME/.e/e/config/standard" and found files such as:
"e_randr.cfg" plus "e_randr.1.cfg" thru "e_randr.9.cfg"
But, I can't get to that folder. How to turn on my monitor display?

I'm using Debian Lenny with an nVidia 8400GS. Before I changed motherboards (and graphic cards, as apparently AGP doesn't exist anymore) this set-up worked fine, but with the new hardware, I can't use the TV as a second screen anymore: there's simply no image going through. All that's visible on the screen is "No video signal".I've tried the proprietary nVidia driver and nvidia-settings, but nvidia-settings doesn't even see the second screen. I've tried adding it manually to xorg.conf, but again, nothing.

I'm trying to record my desktop and tested some solutions. While I was impressed how small .mng files could be, it is a disadvantage that I can't capture audio with it and many users won't be able to open these (browser / Windows). I have been very impressed by the xvidcap instruction videos: 4:30 in only 9MB, which makes 180MB for 90 minutes. This would be suitable. With Camtasia my professor even records 90min in 100MB. The problem is that xvidcap hasn't been updated since 2006 and seems to be dead. RecordMyDesktop needs 6MB for 1 minute or 540MB for 90 minutes, which is too much. Could anybody give me some hints on how to capture very small video files, which are still clear enough to read text in a format most users can open? It would also be cool to be able to show specific PDF or HTML pages synchronised to the video.

I've been running Ubuntu for about 2 years now. When I first put it on my Dell it was 9.0x. My HDMI port worked just fine to connect to my Plasma to watch movies on. I've only ever connected it 2-3 times. Since Fall '08 I haven't used it again. I never needed to.
Since that time, it stopped working. When available I upgraded to 9.04, 9.40 and now (effective 10.23.10) 10.04. It just doesn't work anymore. Neither VGA or HDMI. I can only assume S-Video will be the same story. Video card is an NVIDIA GeForce 8400m GS. Driver is version 173. I installed NVTV tv out (Nvidia Video output controller). It does nothing. When NVTV is typed into terminal, it says; Fatal: No supported video card found.

In the control centre under multi media selector for configuring GStreamer it has Autodetect and two other setting, X Window System (No Xv) and X Window System (X11/XShm/Xv) etc. When I test the X Window System (No Xv) the test card in full screen is far better then autodetect, should I keep this setting, the reason I ask is I can't notice the difference when watching video.

I've just installed Xubuntu 10.10 on a ThinkPad R50e and on a R51. I want to get them working as fast as possible. Of cause, all updates are done and all codecs for gstreamer have been installed, too.
Parole Media Player tells me to not be able to initialise Xv output, so no video appears on screen.
Then I've started to search for the cause of trouble. Seems to be an Intel grafics adaptor handled by the Vesa module, which I don't know how to change to the correct Intel module (which is installed, by the way).
I've googled for this issue and found few other people talking about. But there was no solution, at least none that I could understand.
Now, I would be really glad if you could help me to find a working solution during the next few days.
Code:
~$ xvinfo
X-Video Extension version 2.2
screen #0
no adaptors present
Code:
~$ lspci

I'm running Ubuntu 10.10 w/ an ATI HD 4350 and trying to output to a CRT television over S-Video @ 640x480. Problem is the screen blanks out after ten minutes no matter how I configure my screensaver or power management settings. I've done some research regarding commands in Terminal, but I can't find anything straightforward.
