By "on various NVIDIA boards" do you mean motherboards which have the nVidia video chip on board and it, rather than a separate, plugin, nVidia video card is what you use for video? If so then I cannot comment because I have always used a plugin video card, and I have never had the problem you describe above with any of the "external" nVidia cards.

Hi Basil, No, these were PCI-X bus, separate video cards. I've seen it on at least three different models. I wonder what I'm doing different? I saw it on both KDE 3.5 and 4.1. Odd.

Look at the BIOS. Whe something like this occurs I normally reset the BIOS to default settings then go thru them to make they are set to what works. For example, Linux expects the BIOS to be in control so I deselect the PnP setting. You are using PCI (Express) card/s - is the Initial Display set to AGP or PCI? is the Onboard Video chip swithced off? and so on. I am at present using 11.2 (latest upgrade) and am not having the problem, neither have I had it since I started using Linux so I guess the answer may lie in the way your BIOS is configured.

Hi Basil,

Good suggestions, but I've seen this on HPs and Dells with different mobos and bioses. I also didn't see it with 11.0 and 10.x. I also don't see it with the OSS NVIDIA drivers that come with the distribution, only with the proprietary drivers downloaded from nvidia.com.

Regards, Lew

Well, I always download the drivers from nVidia and compile them against the installed kernel. So now what's your new reason for your problem? :-) :-) Ah, I know, it's global warming, right? :-D BC -- I work to live not live to work. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

That's it!!! I forgot to pray before Gore's Alter of the Sacred Gases!! I'll let you know how that works...

By the way, I haven't posted any AGW skeptical references recently, don't get me started! :-)

I am not sure whether this is a NVidia-only problem! There was a discussion in the German mailing list [0]: * at least ATI and NVidia are affected * happens only when using KDM4 * changing the design of KDM4 helps * for NVidia cards, adding the 'background="true"' attribute to the background tag in /usr/share/kde4/apps/kdm/themes/SUSE/suse.xml fixes the probelm

BTW, there is a bug report (Intel 945GM): https://bugzilla.novell.com/show_bug.cgi?id=461871

I assume that "KDM4" refers to the KDE logon manager. If so, for the record, I have never used Gnome and yet I have never had the problem Lew mentioned. Same thing on my wife's computer. Ah, perhaps the answer lies in the fact that I have never had anything Intel installed.

I see the horizontal disruptions when changing from an X display to a tty.

As far as I understand, the original poster refers to the artifacts of the previous session when logging in.

[...] And, the background="true" does not solve it as it *was* "true" in /usr/share/kde4/apps/kdm/themes/SUSE/suse.xml.

IMHO, your horizontal disruptions are another problem. Gruß Jan -- Colorless green ideas sleep furiously. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

I've been observing a failure of 11.1 to clear the video buffer on various NVIDIA boards when using the proprietary driver. I first noticed this with 11.1, with various versions of NVIDIA's drivers. The problem appears during the login process when bits and pieces of previous images flash on the screen. This is certainly annoying and is embarrassing to have to explain this behavior to customers. Further, it's a security issue since username/password information might be compromised.

I'm thinking it must be an issue with the X server on 11.1 and really hope it doesn't resurface with 11.2. Anyone else notice it? I used to see this on 11.1 and 11.2 thru RC1. Look at

/usr/share/kde4/apps/kdm/themes/SUSE/suse.xml

make sure line five(5) reads as follows:

<item type="pixmap" id="background" background="true">

What I was seeing, after installing the Nvidia driver something was deleting the background="true" from the line. This caused either a checkerboard or various pieces of the previous desktop to appear at various times during boot.

I am now on 11.2 RC2 with the latest Nvidia driver: NVIDIA-Linux- x86_64-190.42-pkg2.run. Problem has not re-occurred.

Whoot! That was it! Good catch! Not only that, but I found the background graphic (Background.jpg) for the login screen! I've needed to present users with a legal login warning, before they logged in, for a long time now. Windoze can do this. Ssh can present a message before login, but it appears only on ssh connections of course. I can annotate this rather ugly low-res jpg with my text, or come up with a nicer background.

Hope this helps.

I am running a 9800GT with the Nvidia driver 185.18.36 compiled locally against my kernel. I see this occur on login but only on the second monitor (I'm running twinview). This did *not" happen with my previous GeForce FX5500 card running the same driver - it only started when I upgraded to the 9800GT. Yes, I checked the above file and the background="true" parameter is indeed present and accounted for (despite having recently reinstalled the nvidia driver after an X11 update). -- =================================================== Rodney Baker VK5ZTV rodney.baker@iinet.net.au =================================================== -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Actually it looks like it has been fixed on 11.2 RC2 - I just logged out and back in again and both screens are showing the suse background instead of garbage on the second monitor. It has been so long since I did that that I hadn't actually noticed it was fixed :-).

I see it on rc2, but not on ll.3-pre-whatever-is-current w/190.42 on both.
