Ubuntu Networking :: No Network On Boot With HDMI Screen?
Jan 15, 2010
I've been experiencing a really strange issue regarding networking. I just installed Ubuntu 9.10 for use as a server/media box, which is connected via HDMI to a TV. Everything seems to be working fine, but there's one peculiarity: the machine doesn't connect to the network (so I can't SSH to it or anything) until it loads on the HDMI display. While it's not a big deal to turn on the HDMI display and wait for Ubuntu to show GDM, I was wondering if anyone knows why I'd have to start up GDM for the machine to connect to the network, and if there's a way to fix it.
I did notice after unplugging the HDMI cable and rebooting that networking started without any trouble after boot. But it's also not very convenient to have to unplug the HDMI cable every time booting!
Not sure if it's relevant, but the graphics card is an ATI Radeon HD 4350, and I'm using the binary ATI driver (otherwise HDMI doesn't work).

I installed ubuntu 10.4.I am getting no screen on my display by HDMI. I installed after that the nvia driver but it won't work 800*600 by 60hz .My display works fine with Windows 7 on my other computer. I do my first steps with an open scoure OS so does Ubuntu support HDMI?

I have an Okano 42" LCD TV, which I connect to my laptop via HDMI cable. Unfortunately, it doesn't fit the screen at the TV's resolution of 1920x1080, and there are about 40 pixels that run over the edge of each side on the TV, making the Ubuntu toolbars invisible.The standard NVIDIA control panel doesn't have any options for correcting this (in windows it had settings for adjusting the stretch/position of the screen), so I was wondering whether there are any common tools that ubuntu users can use to adjust the relative position and stretch of a screen?
BTW I think the cause of this is that my dodgy TV isn't correctly reporting its resolution to the laptop, and unlike most branded TVs, I don't have any system settings that can be adjusted to correct this (I know the panasonic counterpart can fix this in the system menu)..

So yesterday I had plugged my laptop into one of the tv's at work using HDMI, it worked great but no matter where I played in the setting's I could not figure a way to play the movie and be able to close my laptop lid with out it going into a sleep mode. I tried it in the power management but could not get it to work.

When I did this in Win 7, the best resolution to use for TV display was 1280x720. When I hook my laptop up in Ubuntu, this resolution is unavailable. Why are there less resolutions available in Ubuntu? Is there a way that I can override this? Lastly, Win 7 will remember to reconfigure my resolution when my TV is connected and then switch it back to the monitor's native resolution when disconnected. Is this possible in Linux? I have to attach screenshots because I'm new to the boards and you need 15 posts to link to sites,

I have a system running a very basic LTS install (10.04). Ubuntu has been setup with very little additional packages. No GUI. Once it's booted to a prompt for the first time I add the following packages,
cups cupsys ssh pi memtester nfs-common
aptitude safe-upgrade
At this time I don't have additional information on exactly what packages are installed. I did not perform the installs myself. I will update this thread when I get more details from my IT counterpart on how the system was setup.
This is used for a headless(no monitor, no keyboard) system running some custom applications.
Here are two problems.
1. If I plug into an ethernet network after I boot, the network never connects. I need to reboot with the network connected in order to get an IP. What is the service to "auto connect" to a network?
2. I have a network printer configured on lpd called myprinter. If I am connected to the network when I boot, I can print to this printer just fine using:
Code:
However, If I boot disconnected from the network and print to myprinter, the jobs obviously cannot print. They get spooled. Using 'lpstat -t' I can see that the spooled print jobs are assigned a job number and that myprinter is trying to connect. I shutdown, reconnect my ethernet network and boot up. All my printer configuration is blown away.
/etc/cups/printers.conf has been wiped out to look like this:
Code:
My 'good' printer configuration is copied to printers.conf.O
To recover from this, I need to stop cups, copy printers.conf.O to printers.conf, restart cups, and re-setup my network printer.
So, What causes my printers to get wiped out? I've repeated this on 4 systems with the same setup.

I've just finished installing Ubuntu Server 10.4 onto my ASRock ION330. I don't have a spare monitor lying around, so I've plugged my TV into my machince via HDMI. This works, but the text is tiny. There are too many rows and columns of characters (or equivalently, the font is too small). When I try changing the TV resolution to a smaller size, it just cuts out the rest of the text. So from the command line, how do I make the text bigger?

I have now for two days been battling against my computer. The problem I'm having is that I'm not able to use fglrx as it only gives me a black screen at the time when login screen should appear. I have tried installing from packages, and also building my own packages from the downloaded .run file from amd's website. I have tried reinstalling, reconfiguring, removing xserver-xorg-video-ati and so on, but the problem is basically the same even though sometimes it made the screen turn off instead of just black as it's now and have been for the most setups. I've tried running without xorg.conf and tried making one using aticonfig -initial , either ways the result is the same, blank and black screen.
I can confirm with dmesg | grep fglrx that the module is loaded (even now though I'm actually using radeon driver). The X log in /var/log is just an empty file, so no help there. Actually I started of with this yesterday but with a Debian/lenny installation, and had the same problem (the turning off screen variant). In Debian I couldn't even start X using any other driver (even though I maybe could now after I learned a bit more of how package tools work) so I installed Ubuntu instead. In Ubuntu everything loads but is using the radeon driver as default... Ubuntu though suggested on launch to upgrade to the propriety fglrx driver on launch, but that only made my screen to turn of on next launch...
The reason I really need/want to use fglrx is that I have my receiver connected through the HDMI cable and using it for sound. This works in Windows. As I understand I need to use the fglrx driver to do this in Linux, or do I ? Actually the HDMI out is shown in the mixer settings, but I don't get any sound through it... Guessing that I need to access some CCC settings that I cannot start when using radeon driver. Or should it be enough to get HDMI-out sound just having the fglrx loaded though not using it for graphics? How should I proceed with this situation? Trying to get fglrx to work or trying to get audio to work using radeon driver? And what can I try more? I have actually used both Linux and FreeBSD a bit in the good old days of the late-nineties (remember Slackware 96 ) but don't think I ever had this hard solved problem... My system is:
Ubuntu 10.(4? latest netinstall) x64
C2D E6600 on P5B-deluxe
4GB RAM
ATI HD4350 (1 hdmi, 1 dvi, 1 vga), monitor connected on DVI

i am trying to instal kubuntu 9.10 on my desktop. i have an ati radeon hd 4600 with a hdmi cable going into the 22" lcd. The problem is i cant view the whole desktop, like i can only see a part of the corner, and all of the icons are massize. The search bar at the bottom comes to half my screen size, making installation impossible to see. Plus i can only use live cd mode using safe graphics mode. i am new to linux finding this quite confusing.

I ordered a DELL studio 1536 with AMD turion rm-74 and vista preinstalled. Although it is still in production, I plan to install ubuntu on it and install an xp/vista guest in virtualbox. However, I am wondering if I can do it. There are many questions, partial answers are welcome:
1- Can ubuntu (32 bit or 64 bit) recognize the 1920x1200 screen, webcam, HDMI etc etc? any tricks if it can?
2- Is it possible that I ghost the vista so that I can restore it later in the virtualbox? and can I upgrade it to win7 from vbox? DELL says it is eligible for free upgrade, a very weird option nowadays.
3- To what extend will the guest OS control the machine? For example, is it possible to output a website video (e.g. live TV in bloomberg.com which is only available in windows) from the guest to the HDMI?

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.

Where the script is for Gnome 3. When I plug the HDMI cable, the desktop expands to include both, but disables the backlight on the laptop monitor. I have to restart gdm3 or the laptop for the brightness control to bring it back up. First, why would it turn brightness to 0, and how do I change the default of that so it stops. I plug and unplug the HDMI regualarly while I wait for a new desktop and the laptop has to pull double duty.
I just switched from Ubuntu 14.10. It never blacked out a screen on plug in or removing. That means that there must be some way to do it, however, it used Unity and this is Gnome 3.
I installed KDE. It works as well. I will use it for now, but would like to get Gnome 3 to work. My default is gdm but I think I saw I can switch it to kdm.

I would like to configure my system to do the following. Previous versions of ubuntu did some of this but now I cant seem to get this working.
1.Browse other Ubuntu systems on the local network by default. Avahi is install on my systems but they cant see each other.
2.From the GDM screen log into another PC. I had this set up in the past so from my laptop I could log into my server almost like terminal services. How do I set this up again?
3.Share files on the local network easily. How do share file with other pc on the network if I don�t want to use samba? What happen to NFS in Ubuntu?

I realise this is an issue that has been covered a lot, one way or another, but at least from what I've been able to find, most of the discussion centres around getting HDMI audio to work. However, I have problems even getting the video to work from my laptop's HDMI output.
I have an HP dv6z-se, with an ATI Mobility Radeon HD 6550 (1 Gb) video card and using F14/KDE. My problem is that when I go to System Settings/Display/Monitor, Fedora doesn't actually seem to realise my computer even has an HDMI output and only displays options for VGA and my integrated screen.
When I plug it into my LCD screen, sometimes I get a 'No Signal' message and sometimes I get garbled static and a message about unrecognised input and the frequency it's coming at.
I read elsewhere in the forum that someone was able to get video working by editing their xorg.conf file, so I went in and tried to see if I could replicate that, but none of the files in my xorg.conf.d folder had anything related to video outputs (as far as I can tell at this point).

I have a TV connected to my 11.4 laptop all the time, when I boot Grub outputs its options on the TV screen, then lizard appears for a couple of seconds and then it switches to notebook monitor to continue booting. Or not. About half the time both screens, TV and notebook, go black and nothing happens.
So far I just reboot and wait until the switch from tv to monitor is successful, if that happens everything boots and loads fine. It's like unwatched milk - everything is okay until the moment you turn away and the milk boils over. Boot hardly ever fails if I sit and watch it but sometimes I get two fails in a row.
Never seen this behavior with 11.3 on the same notebook with the same hdmi always plugged in.It's a Core i5 with integrated Intel and a separate nVidia graphic card, what other info is needed? Grub? Dmesg output? Maybe there's a boot log file somewhere, too.

i'm new in linux and i have a problem with my hdmi lcd under linux. To be more precise , my graphic card is an Nvidia GTX 295 with hdmi output to a Dell 2408W LCD screen and the problem is that linux can't see the hdmi connection, working just with DVI or VGA. I also have Windows 7 in dual boot with linux and in windows it works just fine. To mention that i tried several linux distributions: Ubuntu, Ubuntu ultimate 2.7 and Sabayon 5.4.

I have a new install and I am quite surprised it just misses networking. That is, NO networking. ifconfig comes up with inly lo. Nothing else, most primal. It should use dhcp to connect, bit it fails to create the eth0 interface. Such a fundamental flaw is one I can't work on. Forget looking in network manager in the desktop, that's still being installed, I've checked the basic files in etc against karmic.
idella@squeeze:~$ cat /mnt/lucid/etc/network/interfaces
# Used by ifup( and ifdown(. See the interfaces(5) manpage or
# /usr/share/doc/ifupdown/examples for more information.
# The loopback network interface
auto lo
iface lo inet loopback

The computer is not assigned an IP/connected to the network after boot. It does not do so automagically after a few hours either. I'm required to do:
Code:
sudo /etc/init.d/networking restart A few times before I get a connection.

I have two machines running ubuntu connected through a BiPAC 7401VGPR3 (Billion modem/router). One is a new notebook running Ubuntu 11.04 and the other desktop computer is running 10.04 connected to the printer and external hdd.
I can't find the right documentation to network them so that I can share HDD, printers, devices, etc. I can't get either computer to see each other via network searches.
Also may need to boot into Windows from time to time and access the network from there.

I installed Ubuntu with a partition that was too small for any practical use, so I installed it again, thinking it would simply overwrite the other one as Windows would do. Obviously not. Now I have two Ubunto installations, neither of which work. I get a White Screen after the Ubuntu thing that shows its progress. If I try to boot from the CD, the Ubuntu thing works again, then I get a completely garbled screen which is totally unreadable and unuseable. I should also mention that I originally installed with a 19" square flatscreen from HP, but have upgraded to an Acer H233H. Since I have no clue what to do whatsover Ubuntu is just taking up space. I'd like to be able to use it, and I'd like to be able to get rid of one or other of the installations.
