Ubuntu :: Possible To Use Both Displayport And Vga At The Same Time
Dec 25, 2010
I have a T500 laptop that has both a vga and display port output. How well is display port supported in ubuntu? When I google ubunt u, I get a whole bunch of "why isn't this working". Also, Is it possible to use both displayport and vga at the same time (so I could have three screens)?
I have an 27" iMac which I wish to use as display for my Ubuntu machine using it's mini Displayport as perTo that end I bought a new Intel DH67GD motherboard and 2600k CPU and a Displayport->Mini Displayport cable.However it seems that X doesn't detect the displayport connection correctly. When I boot the Ubuntu machine the iMac correctly switches to that input and Intel motherboard screen appears on the display followed by the grub interface.However it seems that when X should start it doesn't recognise the Displayport connection. The iMac goes back to displaying it's own screen and the X logs don't seem to recognise the connection

I have a MacBook Pro 5,2 with the Mini-DisplayPort for external video. I have the displayport-VGA adapter which works (albeit sometimes at an unideal resolution) with an array of projectors, LCDs and other stuff. Everything except for my nice Samsung SyncMaster 2433. When I plug it in, I get the weird rainbow screwed up look with only the far left hand column looking normal and the rest looking like I've got the wrong refresh rate or something. However, the same setup works when I boot from Karmic to OS X. Note this also didn't work in Jaunty. I'm using the NVidia 185.18.36.
It also did not work through a KVM switch (long shot) but oddly the "Monitor Out" works when I run this monitor through my Dell projector. if I unplug the projector and then plug the monitor in directly without rescanning for displays, the monitor continues to work.
I have finally decided to reach out for help because I've been messing around for 3 days with xorg.conf and I'm a beginner and not getting it right. What I want to do is to use only my external monitor (1920x1200) via DisplayPort when my computer is docked. And then my laptop display (1280x800) when undocked. I am using Ubuntu 10.04.
I have setup System->Preference->Monitor: Unchecked <same image in all monitors>, turned off laptop display, and set External monitor to 1920x1200. After doing this everything works when in Xwindows. The resolution is correct when I am docked, and when I am undocked it defaults to my laptop display.
The ONLY problem with using the System->Preferences->Monitor is that when I start up the computer when docked the external monitor goes to the incorrect (laptop screen) resolution at the initial login screen. After I login the resolution corrects itself but it's messy with reinitialization of the screen and my icons being all messed up. I think this happens because these settings only take effect after logging in.
I believe I have to edit the xorg.conf to get my setup working at the login screen. Can someone please tell me how to this.
Apparently you can't get EDID information through a Displayport->DVI adapter. That means that a default install of Lucid (or Natty!) does not recognize the resolutions of any monitor connected with such an adapter.
I'd rather not create an entire multihead xorg.conf just to specify NoDDC. Is there any other way to pass that option to X?
I have a Dell Latitude E6400 with Karmic (Intel graphics chip). Currently, I am trying to connect a 22'' TFT using a DisplayPort to DVI adaptor plug. Unfortunately, it doesn't even seem to find the screen. xrandr does not list it:
[Code]...
I know from another guy who connected an HDMI TV over DisplayPort, and this devices is listed unter "HDMI1", and not "DP1". So I am not quite sure where it would be listed even if it found the screen.
I'm using Jessie 8.3 on Dell laptop Latitude E7240.
Now when I plug the laptop in the Dell eDock docking station, external monitor connected through DisplayPort and it is detected (according to xrandr output).
BUT nothing shows on the monitor (it stays black) and I get errors repeating in the kernel log:
[ 71.064428] [drm:intel_dp_complete_link_train] *ERROR* failed to train DP, aborting.
I'm reloading my X301 Lenovo laptop with linux but need to make sure that whatever distro i choose will support displayport out. I'm currently running XP on it and DisplayPort -> HDMI (via converter) -> Sony 40" 1080 TV works great. Just Shift F7 and I'm off and running.
I tried Mint 10 and Debian 6.0.1 last night (via Live DVD) and while they both recognized the displayport, and I could set the resolution on a second monitor to 1920x1080, the output was scaled incorrectly and didn't show any user mouse movements etc... just the wallpaper basically.
I have a laptop and an external monitor connected via displayport. I can configure both displays via settings with correct resolution and arrangement. However, this configuration is not sticking, and every time I shut down the laptop or close the lid I will need to fight with black screens and more to bring the same configuration again. Basically, it seems that the monitor is "stealing" the primary role to the laptop's native screen (I have it configured as secondary, but also being primary the configuration gets messed).
After many trial & errors, this is the routine I have found to make things work every time I boot / awake the system:
1. Boot. Laptop's display shows the booting sequence. 2. When the login screen should appear, laptop's display goes black, monitor shows background. 3. If I press F9 to increase brightness, the brightness icon appears in the monitor, but it is stuck at the minimum. 4. The only way to leave this point is by pressing F7 (project screen) and then F9 again to increase brightness. Then the laptop's screen does light up.
This is when I'm lucky. Sometimes the configuration goes mad and I get mirrored displays and different resolutions, without touching the settings myself. Also, if I unplug the displayport I run the risk of getting stuck with a black screen in the laptop, without any way of recovering the GUI other than rebooting (Ctrl Alt F2 will still show the command line screen).
My system is Debian 8 testing up to date, running in a Lenovo T430 with Intel components. I'm not sure the monitor is relevant here, but in any case it is an Eizo CS240.
I occasionally use a DisplayPort->HDMI cable to connect my laptop to my AV-Receiver, however I only get the picture to the AV-Receiver, but no sound. I read that not all DisplayPort->HDMI cables support sound, so I tested Windows7 on the same machine and it transmitted sound over that cable just fine. So I conclude that it is a Linux driver problem.
So I generally wonder whether this can be made to work easily or not. Does anyone here have experiences with this topic, especially with nvidia graphics cards managing the display port? (I did find older posts about HDMI audio, but they were all concerned with ATI graphics.)
pavucontrol / phonon do list a "High Definition Audio Controller Digital Stereo (HDMI)"-device, but sending sound to it does not do a thing. Furthermore, my dell laptop only has a displayport, but no HDMI connector.
It takes me a while to log in the splash screen just sits there for ages before i get to the desktop. Never used to be this slow and I'm not sure why. Firstly, I'm running Ubuntu 11.04, standard DE. I do have conky starting up in a script but it has the & at the end of the line so I didn't think this would cause it (or is there some special case for log in time on how & is treated?). However as a test I will comment out the line in the script and see if it is the cause.
However just for general knowledge and in case that isn't the problem, how does one go seeing what is happening during the time from when one log's in and the desktop is displayed? Is there some kind of log that shows the date/time that can be enabled or is there a debug mode that can be enabled somehow via special keys or maybe from grub?
I have several file servers in our offices and I am relatively new to Ubuntu / Linux. I get notices that there are updates for the server software from time to time. Is it typical to update everything when available or should I follow "If it ain't broke, don't fix it..." mentality?I would hate for everything to be working fine and then have an update throw me a curve.
I am running my Ubuntu 32 bit server on top of Windows 7 64 bit with VirualBox. It's a 2 core Atom. It's been working good for about half a year. But the last about 6 weeks the system time only in Ubuntu is going slow. About -8 per 24 hours! I can only guess because I have more things running in my Windows 7 and Ubuntu.
I can set it right by coping the hareware time to system time with this command:
Code: hwclock --hctosys
I want to run a crontab to have that command run every minute. But it don't seem to run.
For like windows you can resore your os to a state of peace kind of. If you messed up your vital files you could go back in time and restore you computer to a selected time. I was wondering if you could do that for ubuntu
Ever since I installed Ubuntu Natty, from time to time, for no particular reason, the entire computer screen freezes, and I am forced to hold the power button on my laptop to restart things with a hard reset. I cannot explain why it happens.
Such an issue never occurred in any of the past installations and versions of Ubuntu. This is a fresh installation of Natty by the way.
Also, I can currently be running a lot or nothing and it does this. Thus, it does not matter what I am actually doing (ie, what programs I might be running).
It has occurred about 10 times since I freshly installed Natty 6 days ago.
I started out with Kubuntu RC, then installed ubuntu-desktop and updated all the way to the current state of packages.Anyway, from the moment I installed the RC, from time to time the boot splash appears, the dots light up/turn off and then the booting hags. No key seems to work.I the do a hard reset and everything works just fine.As not to open another thread:- how can I see the Ubuntu splash screen? (currently I can see the Kubuntu one)- how can I turn the splash off and have it boot in text mode?
When booting Fedora 11, my system hangs for a very long time on starting udev. Sometimes I get an I/O error. However, my hardware is fine. I do eventually get in to the system.
I am using Debian linux. I have 100 timers running. If a timer expired which will generate a signal and it was mapped to a same function handler. All the timers are mapped to one function handler. The problem is if the timer expires one at a time, the function handler called at a time. But if the 2 timers expires at a time, the function handler is called one time only instead 2 times. Is it possible to invoke the function handler as many times based on timer expirary happens simultaneoulsy?
I've got fedora 11 set up to use network time protocol to sync my laptop's date & time when I'm on-line. The question is simple really, I've added a local universality's time server (what is public) and it's live. but it's added to the end of the default time servers what come with fedora. How do I get fedora to just use the local time server, is it a case of removing the default time servers for fedora, but there is a box what says advanced options which are. sync system clock before starting service ???? & use Local time source (( is that the same as the local ntp server that I've got set up ))Hope some body can help me with the network time protocol part of Date/Time settings.
Since the upgrade from Lenny to Squeeze on my Notebook Toshiba Satellite Pro U200 with Intel Pro/Wireless 3945 ABG I have wireless connection problems.The connection breaks time to time and sometimes cannot connect automaticaly after restart. BTW I didn't change anything on the wireless or network configurations on the notebook and on the wiereless router.
In the right upper corner of your screen,you can see if you have a network connection or not.Most of the time I do not have one according to Networkmanager (?).So I have to enable my wired connection manually.I already tried a lot to change my settings so I would have a network connection at boot,but it doesn't seem to work....Firefox is in Offline modus when I logon..
I boot Ubuntu off of an external hard drive just so I don't deal with partitions and crap on the same drive my Windows 7 Ultimate is on. This is a Gateway laptop, BTW. Anyway, after I boot Ubuntu, when I boot into Windows again my time is off by a few time zones.
I installed Ubuntu inside windows(Win 7).Both works good.I found that system time is wrong in both OS.Every time i Change it manually but it changes again on reboot!
I have a Insprion 14R (N4010) and when I hibernate it will usually restore without a problem, but maybe 15% of the time it will reboot while loading. I would like to figure why, since I'd rather not lose anything... My swap space is 5.9GB, I have 4GB RAM (video uses 1gb, so I have 3gb usable)
I'm looking for a program that will digitally display the time in three different cities - all showing at once. I don't care if it is a panel applet or stand-alone. I'm using Suse 11.3 and Gnome.
I have a linux (Slackware) machine and the time/date is like, June 23rd 2003, 10:00am (It's 11 here) and I am not able to set the time to have it correct. I change the timezome to Montreal but the time is still wrong.
Is there a way to force it to sync with my domain controler or even another online NTP server?
