Ubuntu / Apple :: Mini DisplayPort And Samsung SyncMaster 2433?
Jan 19, 2010
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've a Samsung SyncMaster 943, widescreen I also have a GForce 8400 GS This monitor supports (as seen on website) a 1440*900 resolution. I've installed the nvidia driver (from homepage) with version 195.36.24 The NVidia X Server Settings shows only a 1360*768 as max possible resolution. So, I've edited xorg.conf, restarted PC but got no luck... here it is my xorg.conf

I've installed my mythbuntu 9.10 and the ati driver 9.11 via DVI connection to the monitor and all work correctly. Today I bought an HDMI cable because I want to use only this cable to send video and sound to the monitor and as so I connected via HDMI and I started the PC. After the computer starts, it showed correctly the booting information and mythtv but as soon as I exited from mythtv to use the pc as a desktop I found that the chars, the icons as so on were very big. I've tried to run the Ati contol center and the resolution of the monitor was correctly 1680x1050. I've tried to restart the computer with the DVI and all come back to usual, so I tried to switch off the monitor unconnet the DVI and connect again the HDMI and when I switched on the monitor the display was again ok. After a restart of the system the situation was the one I've told before (big chars, etc.).

I upgraded my system to ubuntu 10.04 last night. After the process completed, I restarted my system and there were 2 problems:
1. No flash plugin was found and adobe could not find one on their site.*
2. my flatscreen monitor (Samsung syncmaster 2333) was detected, but the display is fuzzy. I have tried lowering the resolution but this does not work. Is there a fix for this?
Alternately, is it possible for me to revert back to 9.10? I am a Linux novice and I'd rather stick with what works, even if it means I am a release behind.

I've read about a half a dozen threads now on various problems such as mine but haven't found a solution which worked. I recently purchased a new LCD screen which has a native resolution of 2048x1152. After I plugged it in via DVI cable windows 7 picked up on the new display immediately and adjusted my resolution, but when I booted into Ubuntu I don't see either the circle thingy (initial splash screen), I don't see the Ubuntu with the slider deal flashing, and I don't ever get to the desktop. The hard drive is not active and all that happens is I see a flashing cursor then even that goes away after a second or so. I can get to Ubuntu's desktop if I boot to the recovery mode, login, then run "gdm", then it starts up just fine and defaults to the native resolution of my new monitor. How can I fix it so I don't have to do that?
Summary:
- Bought new LCD screen, SyncMaster 2343, resolution 2048x1152 via DVI
- Will not boot normally to Ubuntu 9.10
- See a cursor for 2 seconds, then goes away, no HD activity occurs
- Can boot to recovery mode, type GDM, everything is great
- Windows 7 picked up the new monitor right away, no problems
- Video card is ATI x850
- Running in a dual boot config, partitioned out to win7, winXP, and Linux Ubuntu 9.10

I have changed to Debian 5.0 on this old Gateway box, and the video is the GeForce NV34 FX-5200. I set it up with a Dell monitor and everything works great, I have several screen resolutions avail. But now I changed to the Samsung SyncMaster 731N and now I have only 2 resolution choices. 600x400 and 800X600. Besides move back to the Dell, how can I get the card to work with the monitor?

I'm using an Apple bluetooth keyboard, model A1016 the one with a white bottom inside clear plastic. The machine is a Mac Mini (2,1) and I also have an Apple bluetooth mouse. The mouse works fine on Ubuntu 10.04. The keyboard has issues.
When I add the keyboard using the bluetooth applet, I find that I can't assign a specified PIN. I have to use automatic PIN, and then type the random number presented. That works until I reboot the machine.
After reboot the bluetooth applet menu shows both the mouse (connected) and the keyboard (not connected). If I tell it to connect the keyboard, nothing happens. The only thing I can do is delete the keyboard, re-add it, with a new random PIN.

I set up my Mac Mini to dual boot Windows 7 and Ubuntu. I started with Windows only, and allowed it to rewrite the partition table (GPT/MBR). When I tried to install Ubuntu, it didn't see Windows until I used Gdisk to delete the GPT portion. Then it recognized the Windows partition and installed Ubuntu as per normal. Now when I boot, I get GRUB and the option to boot Ubuntu or Windows 7. The only problem is that the USB keyboard (Aluminum or standard PC keyboard) doesn't work until an OS is loaded.
Is this an EFI problem? I'm starting to think that EFI is required for USB keyboard support at bootup since it replaces the BIOS functionality. Is this even remotely accurate? Did I mess things up by not going the rEFIt route? I'm not sure what I can do at this juncture as I can only boot into Ubuntu.
I could install OS X, rEFIt, then Windows and Ubuntu, keeping rEFIt as the boot loader, but if there's an easy solution I'd like to avoid that. More importantly, I'd like to understand what's going on.

I've got a final revision of the G4 Mac mini, the 1.5GHz model, dual booting 10.04 LTS and OS X. One of the issues I've had is that the internal speaker doesn't work under Linux, or so it's been reported on various post and sites. It turns out it's a simple matter of flipping some ALSA control options. With an ALSA mixer you must enable both the Speaker and the Headphone to get audio to play over the internal speaker. It will still play over the external headphones/speakers if they are still plugged in. I'm not sure if this is a problem with the ALSA, OSS, PCM or snd_powermac drivers or just something setup wonky in the configs. I've used both GNOME ALSA Mixer GUI and the alsamixer command line tool to do this. The alsamixer tool will mostly work in an X-term, as the F-keys don't pass though. It is fully functional on a console login. I also noticed that audio plays back per-user. When I switch from X to a console he sound is cut off, and when I get logged in as the same user the audio comes right back in.

I've been attempting to boot Ubuntu on my Mac Mini with absolutely no success. I tried 32-bit and 64-bit versions of 10.10 and 10.04. In all cases, I see the little keyboard and man at the bottom of the screen and then the screen goes black (i.e. my monitor stops receiving input).
My monitor is connect via the HDMI-to-DVI convertor, so is this a driver issue related to that?

Just bought a new Mac Mini, no optical drive. Using a USB drive, I can get to the EFI grub menu, and boot to the installer menu, but from there the keyboard (USB) doesn't work at all. I've tried every combination of boot flag and am at my wits end. Booting using BIOS results in a "Boot error" message, no grub.Update:Using the 11.04 amd64 iso, I have a slightly different problem. Eventually after grub, I get kicked to a minimal shell (dropbear maybe?) with the complaint "unable to find a live medium." However, from other searches, this may be an issue with a corrupt USB disk, and not a problem with the Mac/EFI boot process.

Anywhere from 2 -> 6 times a day, my computer will freeze up. If any audio was playing, it will repeat the last few seconds over and over again. I've been dealing with the problem for a couple of months now, with no solutions.

I am installing Ubuntu 10.04 on my new Mac Mini. It has 2 500GB hard-drives, and I have created a partition for Ubuntu. During installation, however, Ubuntu is not able to detect my disk drive, neither my network interface. So I am not able to 'Partition Disks' which is part of Ubuntu installation. Did any of you encounter this problem? Any solutions or workarounds? Should I setup my disks in anyway before installation or use boot args?

I just purchased a new Mac Mini 2010 to replace my older Mac Mini 2006 Intel. The problem I am having is that when I boot Ubuntu from the MM 2010 CD-ROM the initial menu that allows you to select a language is displayed, but after that the screen goes blank and stays blank. I am using the HDMI port to DVI output and I am wonder if that could be a cause of the blank screen. Is there a boot command that I can use to allow Ubuntu to display with the HDMI port or other item I need to fix to get Ubuntu CD installer video display to work with my MM 2010?

I want to give a new life to my old Mac Mini that has become too weak for Mac OS ...I successfully installed the Ubuntu 9.10 PPC version (alternate) on the machine. EXCEPT for the support of the wifi antenna. Network manager says: "device not ready". I suppose there is a standard tweak to get over this hurdle.

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 syncmaster 171v, 17 inch monitor which is pretty nice, except that it auto-shuts off after every 2 minutes. Only associated drivers I have found at samsung are for magictune which seems to only work for a 'certain' list of video cards. me not having one for my ubuntu machine. When i plug it into my XP machine (which has one of the special cards, (AGP, ugh), it seems to work, but haven't tested out the long duration.
My current fix for the problem right now is taking the power cord out and plugging it back in. All the buttons on the monitor will not respond after the auto shut off of a whole two minutes. Seems i have a pretty useless monitor if it only works for my old XP machine, and im getting really tired of unplugging it and plugging it back in.

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.

I just got a Samsung SyncMaster T260HD monitor. It works straight out of the box with Windows but I can't seem to get it to work with Linux, which is my primary OS for day to day work.
The computer boots up but when going into graphical mode on Linux the monitor gives me a "Mode not supported" error and doesn't display anything.
I booted up windows and, using PowerStrip, grabbed the exact ModeLine that should be used to get the equivalent setting in Linux and added it to my xorg config file but it doesn't seem to help. the ModeLine is:
ModeLine "1920x1200" 153.9 1920 1984 2016 2080 1200 1203 1209 1235 +hsync -vsync
This is the modeline for the working display settings in windows but it doesn't seem to work in Linux My complete entry in the xorg.conf file for the monitor is
Section "Monitor"
Identifier "Monitor0"
ModelName "SyncMaster"
DisplaySize 518 324
[Code]....
I'm running Scientific Linux 5.4 (clone of Redhat Enterprise Linux 5.4) but I've tried booting with a recent Linux Mint Distro as well as Ubuntu 9.04 and had the same problem.

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:

Connecting my Laptop's Displayport to the HDMI of my TV works fine under Windows Vista in 1080p (1920x1050).
Under Linux the Brightness alternates between high and low every other second.
Otherwise, the picture is fine and sharp. However, the ever alternating brightness makes it unusable.
Anyone any idea what is the reason for this is and how to fix it?
Software: openSuse11.2 (64bit), nvidia 190.53, X.org 11.0. Hardware: Dell m4400, nvidia Quadro FX770M, Sony KDL-37W5810.

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.

so I've got a openSuse 11.3 machine with KDE. As graphic card I've got a 9500GT and as display a syncmaster 570b. Now both work fine with other products (9500GT works fine on my other display and my Windows laptop works fine with the syncmaster 570). I beleive it's because of the frequency. here's a list of frequencies supported by the 570: Technische Daten zu Samsung Syncmaster 570B - TFT Monitor bei dooyoo.de
I also installed nvidia drivers via yast2. But how do I change the frequency? I've been trying to solve the problem for hours. Oh yeah when I connect my 570b to my 9500gt, I sometimes get a picture and sometimes don't. However when I get a picture colors are very strange and it flickers hardly.

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.
