Default LCD native resolution not being recognized through DVI-D connection

Hi all,

First, I would like to say that while researching this in the forum threads, I am impressed with the helpfulness of folks around here. Sure, there is the usual frustration you see in all linux forums, but people are still pretty nice in these parts.

I have been the proud owner of nothing but nForce-based motherboards since they first came out, and have owned at least one motherboard in every generation up through nForce4. (I even have a home theater with 8 foot projection screen based around an nForce2 board with the legendary on-board 5.1 audio!) I have also just switched my linux box to an MSI GeForce 6200TC card (MSI specs) in an attempt to fix some Radeon DVI issues, and I have now replaced them with some GeForce DVI issues...

The system in question is an ECS NFORCE4-A754 board with Athlon64 3300+, running Fedora Core 6 x86_64. The monitor is a 20" Dell 2000FP LCD monitor. I previously had a Radeon 9250 card in the system. However, there is a well-known incompatibility with Radeons and this particular monitor under linux; the monitor does not like the Radeon driver's default 1600x1200 timing, and the Radeon driver has a bug where it ignores modelines. As a result, I am unable to get correct a 1600x1200 display.

I decided to upgrade to the GeForce 6200, but now the default NV driver is not recognizing my Dell 2000FP monitor. It detects a generic digital flat panel display where it thinks "Panel size is 1280 x 1024":

The highest resolution I am able to get is 1280x1024, the resolution it thinks the panel is. I have gone into the Display control panel and selected both the "LCD Panel 1600x1200" and "Dell 2000FP (Digital)" monitor types. When I do this, the resolution appears in the control panel, but when I restart X, the resolution is still 1280x1024 and all higher resolutions disappear from the Display control panel.

I have two Dell 2000FP monitors in my home office. I tried the second monitor/cable to rule out a finicky monitor or bad cable, but I get identical results.

If I switch to the Dsub SVGA connector, the monitor is now recognized and in fact, the box reconfigures itself to 1600x1200 automatically:

I would really like to fix this problem with the NV driver without resorting to the NVIDIA driver. This is a desktop machine, and I want to avoid installing the NVIDIA driver and tying myself to kernel versions, etc.
  1. How can I get the Dell 2000FP monitor to be properly recognized through DVI?
  2. Barring that, how can I change the inferred flat panel resolution to 1600x1200? Is there a magic keyword to set the size or override the size limit/check?

All help would be greatly appreciated! Thanks in advance,

- Chris

Default Re: LCD native resolution not being recognized through DVI-D connection

I haven't made any progress in debugging this issue. I ordered a cheap PCI-Express Radeon X300SE to try out next. When in doubt, throw money at the problem...

The 'nv' driver is actually maintained by the X.org guys, I believe, so I doubt you will be able to get much help from the Nvidia folks who hang around here.

Why do you not want to try the Nvidia drivers? With the nvidia-bug-report.sh, someone here should be able to help you out with any problems.

Thanks for responding, Cambo. I've been around linux for awhile from a user perspective, but I'm still a noob at adminning a box. With the Nvidia drivers, do I need to recompile the driver with every kernel upgrade? Is that a lot less painful than I gather from all the threads I read here?

I've been through a few kernel upgrades. Once the driver has been installed, there is a command 'nvidia-installer' that can be used to update the driver. Calling it with 'nvidia-installer -f' seems to work nicely. That will do a Forced Update, which will also check for any update to the driver. You just need to make sure that when you update your kernel, you update your kernel source files too.

The first time I attempted to install the nVidia drivers a few weeks ago when I first got this card, I ended up with a half-hearted install due to missing packages. It ended up messing up the X configuration enough that it was easiest to just reinstall FC6. (I only need to setup a Samba share and VMware and I'm back in business, so reinstalling is no big deal.)

This time I pre-installed the packages mentioned in the sticky thread, and the installation was nice and smooth. I restarted X and was greeted by a glorious 1600x1200 desktop in its full digital DVI-D glory!

Also interesting is the fact that the nVidia driver does indeed recognize the Dell 2000FP over the DVI-D cable:

This is in direct contract to the nv driver, which clearly complains that it has no idea what monitor it's driving over DVI-D, yet is able to detect the Dell 2000FP over the analog Dsub connection. This appears to be a driver limitation, not a hardware incompatibility.

However, there's yet another wrinkle. (Isn't there always with linux?) There appears to be an incompatibility between the nVidia driver and VMPlayer. When I start VMPlayer, it complains:

Quote:
Failed to autodetect the mouse type. Please set the mouse type and device using Virtual Machine Settings to enable full screen mode for your virtual machine.
Failed to switch to full screen VGA mode.
I'll have to go research this on the VMWare forums, but this didn't happen until I installed the nVidia drivers. I suspect there is some issue with VMWare not being able to render the guest machine directly to the framebuffer.

The reason for all of this is that I got rid of our Windows XP PC, and replaced it with VMPlayer running a WinXP guest. This is the reason a sharp display is a necessity on this machine - this linux box is actually also our primary Windows XP machine!

The new Radeon card arrives by UPS this evening. I'll pop that in just for kicks. Maybe it will just work. In any case, I'll be sure to report back my findings.

Default Re: LCD native resolution not being recognized through DVI-D connection

Well, I made a little bit of progress. I got my tiny little Radeon X300SE (ain't it cute?) and popped it in. The machine rebooted right into a beautiful 1600x1200 desktop over DVI-D with no display artifacting. However, VMWare still starts up with the same fullscreen error message. I'm now suspecting that something in my xorg.conf got tweaked during all this, since it worked fine with the old Radeon card. I know my adventures aren't really GeForce-related anymore, but I did want to come back and update the thread.

Thanks for all your help! Installing the nVidia drivers did seem to get around the EDID-over-DVI-reading bug that the nv drivers had.

Default Re: LCD native resolution not being recognized through DVI-D connection

Hi,

I have the same problem with Ubuntu 7.04, ASUS M2NPV-VM mainboard with NVIDIA GeForce 6150 onbaord and an LG Flatron L2000C (1600x1200) connected via DVI.

I have not tried the nvidia driver yet (because I'm not connected to the net with the PC yet, WiFi USB Stick and WPA, but that's another story).

In the end, the nv driver still seems to have that problem. Have you made any report to x.org about that?

I'm afraid this is a limitation in how the nv driver works on pre-G80 cards.

everytime you upgrade your kernel, just make sure you keep your sources and all links are correct.
the nvidia driver will uninstall previous drivers, create a new install based on your current kernel, and install them, as well as update the xorg config file.
id definitely recommend moving to the nvidia driver.

also, you say your nv driver doesnt detect the resolution correctly, right? is it possible to just force the resolution and rates through the xorg config file? i would just do that (the nvidia driver detects my 2407, but i manually added the correct resolution into my xorg.conf file).

And I assume that my card is "pre-G80"? Thanks for the feedback, Aaron. I also found some comments from you in bugzilla for nv

For the records, I downloaded the nvidia driver:

http://packages.ubuntu.com/feisty/misc/nvidia-glx-new

And used installation method 1 from here:
http://doc.gwos.org/index.php/Latest...E_INSTALLATION

And it works just perfectly
