Ubuntu :: Media PC Won't Boot / Display To HDTV Till Lcd Monitor Is Plugged In
Mar 3, 2010
I am trying to build a media pc, and successfully so till this one little/big problem. I want to be able to turn on my tv, and pc, and have the pc display onto the TV. Ports used are HDMI(pc)->HDMI(HDTV)
But for some reason Ubuntu will not fully load with just the TV plugged in (all i get is a black screen, not even a "no signal" message).Once a LCD monitor is plugged into the VGA port. Then I see a glossy white Ubuntu symbol on the LCD monitor. Then the Ubuntu loading screen appears on both the LCD monitor AND the TV. in mirror mode. And I can see the desktop on both monitor AND TV.
I am using an ATI RAEDON HD 4200 chipset that is on the mobo. I have downloaded the proprietary drivers and installed them. A few things I have tried are the instructions on this page, finding my modeline using a modeline calculator and also going off of a suggestion from a thread on this website, stripping down my xorg file so that the Xserver would autodetect it. Which i think I did wrong because after that, it wouldn't display on TV at all.
So I think it's a problem with the resolution not changing back. But I don't see any menu, like the HP Logo, on my monitor at all. Thought It might be the blue cable, changed it, nothing. Plugged it back into TV and it works fine.
I have a system I use as a file server running Ubuntu 10.04. I don't have a screen hooked up to this system. When this system reboots, if there is no screen, X wont start on it. This then prevents me from using VNC to get to the desktop.If a monitor is plugged in at the time it boots, then everything works, and I can then remove the monitor. But moving this monitor between computers and crawling under desks is not enjoyable.How can I fix this so X starts on boot even when no monitor is plugged in?The error I get in /var/log/Xorg.log* looks like this:
grep -EnC2 "EE|WW|fatal|error" /var/log/Xorg.0.log ... 331- (II) Primary Device is: PCI 01@00:00:0
I have an old computer (Pentium 4) without a monitor. To make the most of it I installed Ubuntu server on it and have been using it for almost a year. A couple of months ago I don't really recall what I did but since then it doesn't start-up unless a monitor was plugged in.
I've tried pinging it but it doesn't respond when no monitor is plugged in. meaning it's not even booting correctly.
I'd like to know what the problem is and how to fix it. And I'd really appreciate any help in diagnosing the problem. I just don't know where to start.
I am running on ubuntu 10.04 and using the latest nvidia driver. What I experience is a random black screen, my monitor goes dead and won't turn back on till I hardboot. I had this issue on windows and solved it by downloading rivatuner and telling it to force my 9700m into staying in 3d performance mode at all times. I know it has nothing to do with temps or anything like that. All I need to know is how I can duplicate what I did with rivatuner on windows
Okay, so here is the deal I have been using Ubuntu for awhile as a network monitoring system and have now changed it to being my main system and was wondering why when my machine is hooked up to my HDTV via a VGA port on the back of VIZIO television, I am only getting a max resolution of 800x600? If anyone can help me with this problem it would be awesome.Any additional information needed please include you terminal commands because I am still just so terrible with those.
I'm running 10.04 as a DVR (mythtv). If the computer boots with the TV off it won't detect the settings, and when I turn the TV on nothing displays. I have to ssh into the computer and reboot it to get it to detect the display.Any idea how I can go about solving this? How can I disable autodetect and force it to use a specific setting?
I setup 10.04 on an older Athlon XP 3000+ ASUS A7N8X board with a Radeon RV250 video card. It works fine and dual boots with XP on the LCD monitor I have. I took it to my mom's an connected to a iiyama Vision Master 450 CRT. When I boot, I get the grub menu, and if I pick Windows XP, it boots fine. If I pick Ubuntu, the screen goes blank, as small underline cursor appears at the top left, and then the monitor goes into sleep mode and the keyboard is no longer responsive.
I cannot seem to gain access. I cannot hit CTl-ALT-F2 (or ALT-F2) to get to text login (screen is sleeping and no keyboard control). I tried Live CD, it shows a graphic at the bottom of the screen and then goes blank as well! Seem like something with monitor resolution, but I cannot seem to figure out how to force it to work. I can't seem to figure out how to get into command line mode on boot either.
I have an Nvidia card and I am using ubuntu 10.04. Before installing the ubuntu nvidia restricted drivers, the boot screen with the ubuntu logo would cover the entire display area of the monitor. But now, after installing the Nvidia driver and fixing the display resolution of the boot screen with the Plymouth fix, the boot screen doesn't expand to fit the entirety of the monitor display area. How can I fix this? There is a good 2 inch off from either side of the display while booting.
I'm trying to get my secondary display (DVI-Out) working on a laptop (built-in monitor & external display) and I'm afraid I made quite the mess of it installing the proprietary driver only to learn that my old ATI card is no longer supported and having to clean that up and reinstall the original distro driver!Anyways, I reverted back to the open source driver and all is ok. That is until I reboot. If I reboot with the DVI display connected then both displays are brought up in 640x480 res and look terrible.
What do I have to do to be able to leave my DVI display connected when I start up the machine and get it to render the way it does when I plug in the display after the machine is running?I suspect I need to create an xorg.conf file but these fancy modern Linuxes these days don't come with one (or maybe they no longer need it anymore).
I have been experiencing this peculiar issue with Ubuntu 9.10. Whenever the system boots, the audio doesn't work but when I do a 'sudo alsa force-reload', the volume icon gets muted and on unmuting it the audio works. This is the information regarding the audio device I get on doing lspci
The computer is used as a server and I connect remotely on it with VNC. It has no monitor. It was working fine until I upgraded to Lucid. Now, it only works with a basic vesa driver (800x600 max res). The log says:
NVIDIA(0): No display devices found for this X screen. Screen(s) found, but none have a usable configuration.
If I plug a monitor, it work fines. Is there a way to disable monitor detection?
I have an Asus eee901 netbook and it's got an Intel 945 graphics card. If I boot it up, log in, attach an external monitor and then open the Display Settings dialog the screen goes black and the laptop appears to crash. Leaving it for a minute or two does nothing.
However, if I boot up with the external monitor attached then I can open the Display Settings dialog and configure both screens.
This is quite annoying as I've got to reboot if I want to connect an external monitor.
Additionally, if booted with the monitor attached and I choose a configuration where the width of the combined screens is greater than 2048, the screens go black and the same lock up appears to occur. Could it be that the Display Settings dialog isn't checking for the maximum display width the driver supports and is then crashing in both scenarios?
I installed Karmic on an older PC I had laying around, and the only trouble I am having is with screen resolution. It uses an old ATI chipset (onboard) for video, and it doesn't seem to do EDID correctly, so I can't display anything higher than 800x600. I have tried creating an xorg.conf, but it's still not working. How can I tell Xorg to ignore the fact it can't detect a widescreen monitor and display something larger than 800x600? I noticed the log says the sync's are out of range, but I am not sure how to fix it.
I've been troubleshooting a friends computer and we've pretty well hit a brick wall. The issue at hand is the video card will not output properly. To be specific, it's an NVidia card with both DVI and VGA ports. We want it to output via the VGA and ignore the DVI because there's nothing plugged in there (the monitor we want to use doesn't support DVI). At any rate, the only time we can get the VGA to work is when we have another monitor plugged into the DVI port and dual head the system. When we do this it also adds an extra "Unknown Monitor" to the display panel. When we just use the DVI the extra "monitor" disappears. now we don't want to have monitor sitting here useless just so we can use the vga out, but there seems little else to do. We tried installing the Nvidia proprietary drivers through the software manager and yum and it failed both ways.
This is really frustrating because it seems like it should be such a simple thing but nothing works. Does anyone else have similar issues? is there something i can do to fix this? I apologize if i've not provided enough info, but ask and i'll post anything you need to diagnose.
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.
I also tried to install Nvidia driver but it crashed the xserver and I had remove the driver.
My Monitor is LG 700E and Graphics card is from intel. as I am not able watch any video.
So I just got a new 1gig HDD and added it to my ubuntu server but if the HDD is plugged in when the computer is off, it will not boot. But if I turn it on and then plug it in, everything is fine.
I dont know whats happening when it tries too, there is no monitor. What logs should I check and what should I look for?
whenever Ubuntu boots, it searches for an external hard drive that I no longer have plugged in. It hangs on the Ubuntu load screen for a while, then says that it cannot find the drive and I have to press (S) to skip the attempt.
After I select to boot Ubuntu (I dual boot Vista Ultimate 64.), it just sits at a black screen with the blinking dash.Cannot enter anything and it will just sit there. But if I plug in my Flash Drive it will boot into Ubuntu either before starting the computer or while Im stuck in the black screen.Plugging in the drive while I am in the black screen will make it boot right up. The drive will light up and a couple lines that quickly say something will show up on the screen and then it boots.This Flash Drive contains Ubuntu and is what I used to Install Ubuntu.
i got a external hard drive for christmas and i installed ubuntu on it. then i couldent boot in to anything if the USB wasent pluged in because of GRUB so i removed GRUB and now i cant see my external USB drive in windows to formate it

I have installed ubuntu 10.10 on and external usb drive and now my computer which runs XP will not boot unless the external drive is connected and on. Can I by pass this situation or do I have to uninstall ubuntu altogether and start over?
I want t understand why my 3G modem work only when it's plugged when my computer boot. If I forget to plug it , I need to restart my machine to get it working. I'm using ubuntu 10.04 when I plug the modem during the boot I get the product id changed from 1446 to 141b and dmesg |grep tty show me that the modem attached to ttyusb0 and ttyusb1 when I plug it after the startup I get also the product id changed from 1446 to 141b but dmesg |grep tty show me nothing.
I installed Ubuntu on to a usb hard drive now without that hard drive plugged in i cant get to my windows(it goes to grub recovery). With it plugged in it lets me pick witch OS to use. How do I get it to just boot right to windows when its not plugged in?
This sounds strange, but my laptop (running 11.2) won't boot correctly unless my external HDD (ext3) is on and plugged in. If I don't turn it on, it hangs at the start of udev. If I press ctrl+c, the system continues to boot, but the keyboard and mouse don't activate... don't function, etc. But I can press my power button and it does shut down. Going through dmesg (during a successful boot with the external HDD on), I saw this (not sure if it is relevant):
Code: [2.201029] scsi 2:0:0:0: Direct-Access Ext Hard Disk PQ: 0 ANSI: 4 [2.201450] usb-storage: device scan complete [2.206637] sd 2:0:0:0: [sdb] Spinning up disk...... [6.062434] udev: starting version 146 [6.225262] . The device sdb1 is the HDD.
Now, I don't know much about udev. I can tell you that I have no sdb1 lines in /etc/fstab, and I have no autofs references to it.
I was building LFS on a pendrive this morning when it crashed in the middle of making gcc. I rebooted without my pendrive and I never got into the desktop. Instead, I get a visually pleasing terminal telling me that it couldn't find and that the only way to reboot would be to press CTRL+D. I'm then given a command line and that's that.
Rebooting with the key inside works perfectly.
I reformatted my key and now there's nothing on it. I feel like somewhere somehow I added an entry to the boot process of my system and now I have to remove it. Never dealt with something like this before
I successfully installed linux mint 9 and at the same time update the system. Now that everything is running, I returned the pc to the owner, but when I power it on, no display. You can see the post but no display after that. And 1 more, I press the shift while loading grub2, nope nothing happens. And also tried booting the CD installer, same results.
I installed the system using an old 15" CRT monitor and the owner had a AOC 1619sw LCD monitor. I found this thread from ubuntu which I think was the same problem as mine, [ubuntu] Help! No display/keyboard on boot with differnet monitor - Ubuntu Forums, but no solutions yet.
I have connected (sata cable I mean) the drive where I have got my Ubuntu installation to another pc with windows 7 64 bits (but I think that 32 and 64 doesn't make difference). Windows 7 doesn't boot. So I thought it may be some kind of issue with the hard drive itself (but the drive is healthy), anyway I have plugged one drive from one NAS (you know, NAS drives are linux partitioned and formatted).Same result: windows 7 doesn't boot.
Windows 7 boot sequence hangs and at the next boot prompts "Repair windows installation" "Boot windows normally" (and obviously none of the options works)
Looks really like that Windows 7 doesn't boot if any linux partitioned and formatted drive is present.
I'm having some strange problems with my monitor. It's an LG Flatron L1730S and the graphics card is a Nvidia Geforce 5600FX. The monitor is listed as unknown in monitor settings and is going at 51 HZ with performance and out of range issues in some game. How can I get ubuntu to recognise it, or better yet change the driver?I did some googling and discovered a tool called displayconfig-gtk, but I can't install it in Ubuntu 10.04
