Ubuntu :: Will Not Display - No Signal
Jan 16, 2010
When I start Ubuntu, the Ubuntu logo appears, then the screen goes black and "No Signal" appears on the monitor screen.
Earlier today, I installed a new processor, a dual-channel AMD from a single channel AMD. I decided to put the entire computer into a new case since I was dismantling everything. I have two hard drives: one for Ubuntu and one for Windows XP.
When I started it up, I got errors 13 and 17. I went into the BIOS and changed the disk order. Now Grub appears and I can get into Windows, but I cannot get into Ubuntu.

If I turn off the monitors, I get a black screen (the monitors goes to power save) when I turn them on again.
I have a workaround which involves pressing ctrl-alt and f3 and then ctrl-alt f7. That usually works and brings up the graphical login-screen. And I get my session back.
But sometimes when I log in, my session is gone. It is as if I was logged out or the system has rebooted.
I have two monitors and Nvidia.

Have a Compaq Presario SR1915AN desktop with a NVIDIA GeForce 6150 LE it has a dual boot of Windows XP and Debian 5.0.6 which would only run in 800x600 mode.I decided to install Ubuntu 10.10 Desktop as this is what is on another different machine, thought it would be safe.The install wouldn't work, I would get the purple selections screen and first time chose the normal graphic mode, 10 seconds or so in to the install the scrren goes dead and i see the "No Signal Input" display show on the screen. Rebooted and selected text mode install, this time it fully installed but on reboot it again has the screen goes dead 10 seconds after you select from the Grub screen.

I recently upgraded from 9.04 to 9.10 on an IBM Intellistation Z Pro (64-bit).Install went smoothly.Upon restart, everything works fine up until the log-in screen. The normal hardware checks all run and the new white Ubuntu symbol appears but when it switches to the log-in screen, a "No signal" message appears on the display and the green power light goes orange.
I can still log-in remotely from another machine and access all the files and drives, run jobs etc., so the machine did start-up properly, it is just an issue with the display.

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?

Hi I am new to ubuntu and am having major problems setting my displays up. my setup is a hd TV to the Left of my pc monitor, i have managed to configure catalyst to let me have a main display with the second display being an extension of the first, the problem is i cannot seem to swap my primary display, at the minute my HDTV has all the taskbars and everything on it while my pc monitor is just a blank background, i would like it so i could start a film playing for my children, then drag it across to the HDTV while i can still use my pc in the background.

I have a fresh install of OpenSUSE 11.4 64bit and I have installed the AMD Display drivers for my Radeon HD 5970. Everything seems to be working quite well. I have a multiple monitor setup (1280x1024 monitor and a 1920x1080 monitor).
I have my primary display set to 1920x1080, however when I try to enable the second display, I get a CRTC error that the display is over the maximum (1920x1920). If I enable both monitors at lower resolutions, there is no problem.
I have done a fair bit of reading and have been unable to determine where this maximum is set, or how to change it. I'd like to be able to run both monitors at their native resolutions.

When i ssh to server using -X, i always confuse about which display number i should export. It seems to me sometimes the display number has been used by something, so what i can do is only
export DISPLAY=localhost:0 && xclock
export DISPLAY=localhost:1 && xclock
export DISPLAY=localhost:2 && xclock
[code]....

About 50% of the time when I boot my 64 bit Ubuntu 9.10 machine, while Ubuntu is loading, my screen will go black and my monitor tells me it is receiving no signal. From here, I have about a 20% chance of getting signal back if I pound my keyboard to death or turn my monitor off/on multiple times.

Ok, first off I installed the disc after having to holed select for the language to come up then selected the nomodeset option before installing, then I installed, restarted and got no signal. After that I tried to edit the grub like a thread said by changing splash or whatever to nomodeset and it won't allow me to edit.

I did not have any /etc/X11/xorg.conf, so I read on these forums that system-config-display would create one for me. I ran system-config-display and it created an xorg.conf. But now my display is all messed up!! So, I deleted the xorg.conf and nothing changed. Why on earth would the display still be messed up if I deleted the file that was causing it?? Does system-config-display change somethign else?

I have the following scenario that doesn't seem to work normally. I have a windows 7 pc from which I am using putty to connect to my other linux servers (all running redhat 5 and 6). So here is the scenario that works and one that does not work. And I'm trying to figure out the one that does not work. Scenario that works:
From windows 7 (putty) I ssh into Linux_Server_1.
echo $DISPLAY
localhost:10.0
I run xclock and I see it pop up on my windows 7 pc. I am using xming on windows 7 to help me populate the display from linux to windows. One that does not work:
From windows 7 (putty) I ssh into Linux_Server_1. Then from Linux_Server_1 I ssh into Linux_Server_2.
echo $DISPLAY
<no output>
I try to setup $DISPLAY with localhost:10.0 or 0.0 or even my windows 7 pc ip address:0.0 ....etc Then when I try to run xclock I doesn't work.
I get these error messages: Error: Can't open display: <ip of display>
Also as a side note all our Linux servers are sitting on one subnet. My pc is sitting on another subnet. I use vpn to connect to the subnet where the servers sit from my pc.

I was running windows vista 32 bit (NOW UBUNTU 9.10) on my custom built pc with a TP-LINK TL-WN353GD wireless pci card, before on vista my wifi signal strength would be in the low 70% range with a speed of 54 Mbps from a access point roughly 250 yards away, now with ubuntu 9.10 signal strength in the 15-20% range with a speed of 1 Mbps. My question is, what is the best way to overcome this wifi signal strength and speed problem, it is a noticable performance disadvatange easily seen on a website like ..... where as before videos would play 95% of the time without having to stop and catch up, would a different wireless pci card be a better choice than what I have, or is the problem in the software as in a driver incompatability or lack of correct driver, not sure how to remedy the problem.

I have installed Lucid on my G4 Cube and it works fine except that I only get a video signal on the VGA connector. I would like to use my 15" Apple Studio LCD, but cannot get a signal on the ADC connector. If I boot the the original OS 9 CD, it works, so I don't think it is a hardware problem. I have tried creating an xorg.conf file with many different setting - still no signal to the LCD.

I installed 10.04 1st by making a partition with bootcamp on MacOSX.Then I formatted the partition according to Ubuntu's instructions. I didn't install rEFIt, because I prefer to just hit the alt (option) key.I made the necessary adjustments according to URL...Community Ubuntu Documentation - and everything seemed to be working fine.I upgraded to Maverick and everything seemed to be working fine aswell.But then I noticed, that the wireless signal keeps failing and I'm asked to put the password again and again..
I don't think this is due to the upgrade from 10.04 to 10.10, but I just noticed it recently, maybe because of the air humidity, the signal was stronger a few days a go.. don't know!!Is there anything I can do?Perhaps install a new driver, or another wificlient, like Wifi-Radar??

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?

I installed WICD because I was looking around the internet and the Ubuntu forums said that it was the best fix for the Network Manager not working. I added the source and installed the package like the Ubuntu site said. I go to Applications => Internet => Wicd Network Manager. It says no wireless networks found. I know that the router is working because my sister is right here next to me playing Maplestory on her laptop! When I do the lshw -C network function in the terminal it is only bringing up two things: the network controller and the ethernet controller. I used Yahoo Answers as my first goto and the answers there said that Linux doesn't have the drivers for the router. I have a Netgear Wireless-N 300 Router WNR2000 and a Dell Inspiron 1750, if that helps. Can someone give me a link to the drivers or tell me in detail what to do?

About 2 weeks ago I upgraded my Ubuntu OS from 8.04 to 8.10 and then to 9.04 with kernel 2.6.28 - 10 - Generic.Today I discovered K9Copy no longer works. When I start K9Copy it comes up ok but if I click on anything in the main window (file, copy, etc.) I get a message that says:A fatal error occured.The application K9Copy crashed and caused the signal 11 (SIGSEGV)

I basically destroyed my laptop a couple of years ago. Windows XP wouldn't even start but it didn't come with an installation disk. I tried recovering it but it just died. So a few months ago I put a box of thing on top of it which broke the screen! I was going to chuck it out until I stumbled upon a page which told you you could use it as a web server.
I decided to use it to host my website. I installed ubuntu without a problem however it wasn't until I was about to start it up I found out it was against BT's terms and conditions!! So since I installed ubuntu I thought I might as well make use of it and use it to render my files. When I went to turn it on for the second time and plugged it into the monitor it said input signal out of range!
I can see the login screen but I can't move the mouse or anything. I can't access the terminal, how can fix this?

I have been trying to put together a mythbox for myself. I installed Ubuntu 10.10 and the newest version of the Mythbox backend. My capture card that I am having issues with is a Hauppauge Wintv-HVR-1850 card, I followed the instructions on installation from linuxtv.org and did not get any errors. I tried to set up Mythtv and it didn't get a signal and couldn't find any channels. I would like to know if my card is even working so I tried using xawtv but still could not get a signal from my card.
how I can verify that my card is installed correctly?

I just installed 10.10 on a Dell Inspiron 1300. The wired connection(eth0) works fine but I get no wireless signal when I unplug and try to connect to my network/internet. It shows that wlan0 does exist but it gets no signal. I've used the rfkill to make sure that it wasn't blocked and everything seems to be ok, except I get no wireless signal.
I uninstalled Network Manager and installed Wcid and it found nothing. I even tried installing several signal scanners I found in the package manager. I've removed, updated and reinstalled the broadcom drivers. I still get nothing. The wireless signal from my router is nonexistent according to Ubuntu.
The wireless works fine when I put my windows XP HD in and it also works fine when I put my Mepix or PCLinux OS HDs in the laptop. So I know that the wireless card is not busted.
