Unhappy New Widescreen Monitor Problems...Flickering and Blanking

I just got a new 22" widescreen monitor and am having trouble getting it working right in Linux (several distros). When I try to use the full resolution (1680x1050) it begins to flicker as I move the mouse or windows around. After just a second or two of flickering, the monitor blanks and then turns back on momentarily. I have tried Ubuntu, PCLinuxOS, and SuSE, but the symptoms are always the same, both while running live CDs and installing to my hard drive. I have the following configuration:

Acer AL2216W bd with HDCP
Nvidia GeForce MX 440 128 MB 8x AGP
DVI connection

The only way I have seen it not flicker is at 1280x1024 resolution, stretched and ugly. The setup works in windows except that I can only go to 1440x900. But there is no flicker.

I have verified in each distro that my video card was recognized correctly. I even installed the newest drivers directly from Nvidia. My monitor is recognized correctly and the resolution is automatically recognized. As far as I can tell, the horizontal and vertical refresh rates fall within the range of my monitor.

There was one particular xorg.conf that worked in PCLinuxOS without problems (it had been backed up by the Nvidia install, and I later restored it) until I tried to install an X11 library and rebooted. Then the problems occurred again and I gave up.

PLEASE HELP! This is very frustrating, as I am trying to make a switch to Linux in the near future (however if I cannot get this monitor working, I may not).

Maybe that video card does not have the capability to run that monitor at it's standard resolution?

What does /var/log/Xorg.0.log say in this section, especially the last time it's in that log:

Xorg.0.log snippet
I checked my Xorg.0.log for openSuSE. I noticed that it says "NV" instead of "NVIDIA", and I remember reading that the default NV driver has problems at times. I haven't yet installed the latest Nvidia drivers, as this was a last-ditch effort to see if SuSE would set it up correctly out of the box. However, in other distros, I installed the Nvidia driver and it installed properly, except that it defaulted to 1280x1024 (stretched) resolution and I couldn't change it. I was able to change it in my hardware settings, but KDE seems to use a different source for its resolution list and I could not go above 1280x1024.

Here is a (rather large) snippet of my Xorg.0.log:

The NV driver supports only the most basic nvidia features.

That video card of yours is pretty old, is it not?

Some months ago I replaced my 19" CRT with a 22" LCD monitor, and promptly had to replace my 6 year old nvidia GEForce GTS card in order to use it.

Yup, it's old
Yeah my card is actually pretty old. But when I was running at 1280x1024 with my CRT monitor I was amazed at how fast it ran compiz fusion.

I was hoping to scrape some more life out of my PC, figuring out which linux distro to use along the way. I'm hoping to build a new PC soon (as my hardware is too old to just be able to upgrade the video card). It looks like I may just have to take the plunge.

What baffles me about this whole situation is that I actually had this setup working fine for one session in PCLinuxOS, which makes me think that it's not necessarily my hardware that's the problem. I wish I would have backed up my xorg.conf at that point!

Just as I suspected. Here's your problem:
Quote:
(--) NV(0): Chipset: "GeForce4 MX 440 with AGP8X"
It's only designed to run up to 1024x768@60Hz on a digital flat panel display (DFP), because of it's pixel clock maximum (which is not greater than 135MHz for DVI).

But check out the available display modes for you monitor in it's manual. If you run that card, you may possibly get SXGA 1280x1024@63Hz. And that probably doesn't look very good.

If you want to run that Acer monitor as WXGA+ with 1680x1050 then you need 146.25MHz pixel clock, which your card cannot do.

Two suggestions: buy a new card, and use the Nvidia driver. A GeForce 6200 or better will work okay.

I bought an AOC 203Vw+ 20" widescreen monitor this week, and ran into the same problem. No flickering or blanking, but I couldn't display the monitor's 1680x1050@60Hz recommended/maximum resolution -- and everything it would display looked horrible.

However, I found a way to trick /etc/X11/xorg.conf into displaying that resolution anyway. It looks very nice, but I don't know if this might be damaging the card or monitor. Today I'm going to buy a new video card. NB: My card is a GeForce FX 5200, which is more card than yours to begin with.

Notice: Use these settings with full knowledge that it causes the driver to bypass the card's capability, and afaik could damage your hardware.

That being said, the line I added to my /etc/X11/xorg.conf file is:
Code:
Option "ModeValidation" "NoMaxPClkCheck"
in the Monitor section. Here's my xorg.conf from there to the end:

You can see I tried several custom modelines, none of which were helpful. Because my card wasn't designed to run a monitor at 146.25MHz dot clock.

My advice is to use your monitor's specific HorizSync, VertRefresh, DisplaySize, and get a new video card.

I suggest you try
Code:
    Option         "HWcursor" "off"
in the Screen section.

Looking at the Xorg.0.log, the driver seems to think your 1680x1050 mode is ok.

Thanks for the suggestions...
I tried your suggestion, Bruce, (adding Option "ModeValidation" "NoMaxPClkCheck") and it went back to 1680x1050 resolution without a hitch and looks beautiful. However there's still some flickering and blanking, though a little less than before. I think you're right...my video card just wasn't meant to produce this output. But at least I had a chance to try out compiz fusion at full resolution. I'll be putting together a core 2 duo soon with a GeForce 8500 soon that will blow away my current setup.

Though I am quite impressed that my old school MX 440 did as well as it did with compiz fusion and everything. I installed linux with the hopes of using it, though doubting that I'd be able to get it working with any kind of decent framerate. But even at 1680x1050, it does well enough to show it off.
