Re: JW199D and Ubuntu Hardy Heron 8.04


I love my new HG and am running it on an AMD64 with Ubuntu 8.04. Generally it works fine but I get one artifact. Periodically I get an apparent random set of horizontal lines. They come and go when the screen refreshes. I thought it might have something to do with the refresh rate settings but no matter what I tried I could not make them go away.

Would appreciate any ideas you have.

Do you get these lines when you're using any other OS on the machine?

You can download a Live CD for different distros and see if you get similar random lines. is a great source for these.

The other culprits are loose VGA cable connection to your monitor, or loose fitting card on the motherboard (unless it's built in).

If you can't get the lines to go away, then you may want to invoke the 3-year warranty on the JW199D.

Hi. Update drivers for Ubuntu?

There's probably no need as long as the aspect ratio is set to your liking:

System > Preferences > Display

However, if you need a better experience in Ubuntu, you might consider looking into your video card. There are some proprietary drivers out there, notably Nvidia, which are also free to download and use, though you'll never get the source code.

There is no need for drivers at your problem. Just check out the area around the buttons (and the buttons) for "locked in press status" case. In other words I suppose that one of the buttons is pressed and keeps the OSD on. Try pushing them to feel the click of the button.
Post back with the results.
Thanks and regards

it's your graphics card not the monitor that often has proprietary drivers to drive compiz and other effects.

If this is not a laptop, then it is easy to interchange.

Nvidia is one such vendor that supplies special drivers for Ubuntu

I have a Compaq FP 5314 that flashes on and off at about every four seconds. It works on XP and shows everything up to the OS coming on. That is all the bios type info, but then starts flashing as above....

The problem is that UBUNTU is setting the screen-resolution to some values that your monitor does not support, e.g., 1920-by-1080, or not setting it to 60Hz.

During boot-up, your monitor uses 800-by-600, so it "initially" works, both with UBUNTU and XP.

Windows "detects" the monitor, and selects "usable" settings.

Attach a new monitor to UBUNTU, and then set the video-resolution to 1024-by-768 and to 60 Hz -- your Compaq should support those settings.

Did you try booting from the Ubuntu cd and ran the desktop live cd demo ? That will bypass the windows drivers and uses ubuntu stuff only so if that worked your instal should have worked. It sounds like it doesn't like your video card as a guess.

I've never had that problem in a install but I would bet they have on the ubuntu support forum.

I think you will be able to get your answer there. If you can't find it using the search ( I tried. didn't) then post it and give a bit more info such as ubuntu version, and so on. Lots of good help there. Once you get it running you will be quite happy with it.

Monitor displays breifly then goes to blank screen

The green power light indicates that the monitor is receiving from the computer correctly. I suspect it is going into high voltage shutdown. There is a safety circuit that monitors the high voltage and shuts the monitor down if it sees anything amiss. So the monitor comes on and then shuts off. High voltage problems are generally not worth trying to repair. Another example of a worthless safety feature. High voltage failures are not dangerous, and adding the safety circuit just kills the unit when it may have some life left or worse, sometimes it is the shutdown circuit itself which fails!
Hope this helps.
