Weird resolution issue

MagnusB · June 17, 2008

I have just installed Mandriva on a desktop with a nVidia card:

03:00.0 VGA compatible controller: nVidia Corporation NV44 [GeForce 6200 LE] (rev a1)

And today I was messing about with the fonts, as they are a bit blurry, and checking nVidia Display Settings I saw the resolution was set to 1280x720, same with System - Preferences - Screen Resolution, but drakconf showed the resolution to be 1366x768 (the correct one). Just to be sure, I took a screenshot and checked, it was 1280x720. I found that strange, so I thought I had to change xorg.conf, but cat /etc/X11/xorg.conf | grep Mode gave me this:

ModeLine "1366x768" 85.5 1366 1435 1578 1790 768 771 781 798 +hsync -vsync

So clearly xorg.conf is correct, but the Screen Resolution utility does not allow me to increase the resolution above 1280x720. Could it be limitation in with hardware? If so, strange, I ran the max resolution on this screen with a much older Intel card. And I seem to remember that this same card allowed me to run it at 1366x769 in Windooze.

Running Mandriva 2008 Spring (Powerpack), currently in GNOME but I have KDE installed as well, and running Compiz. Will check if I get the correct resolution in KDE, but I would prefer it to be correct in GNOME as well...

Please attach your complete /etc/X11/xorg.conf file here for us to see? You can attach it as a .txt file if you like.

Funny thing is that nVidia settings display it as CRT-0, doubt that it matters though.

Try logging into kde and using the KRandRTray tool(Menu>Tools>System Tools>KRandRTray). That will put the KRandRTray icon in your kicker on the right hand side. Right clicking on that icon will give you a list of the screen resolutions and refresh rates available.

but the Screen Resolution utility does not allow me to increase the resolution above 1280x720

Open the Mandriva control centre>hardware>set up the graphical server>resolution. From the drop down list choose other, this should give you a much bigger list of resolutions. Does that solve the problem?

The Mandriva Control Center is set to 1366x768, but the actual resolution is 1280x720. That is why I find it so weird..

EDIT:

Same issue in KDE, KRandR won't go above 1280x720.

Post your /var/log/Xorg.0.log . There's probably an error preventing 1366x768 from working.

drakx11 is prescriptive not descriptive: that is, the resolution it shows is the one you tell it to try and set via xorg.conf . It doesn't detect what resolution is actually being *used* and tell you what that is - it just shows what you're *trying* to use. :)

MagnusB · June 19, 2008

Post your /var/log/Xorg.0.log .

It said: "(WW) NVIDIA(0): No valid modes for "1366x768"; removing."

Complete log attached, the only thing I notice is that it calls my screen CRT-0, while it isn't a CRT screen. But since it is just a name, that shouldn't matter?

Xorg.txt

In kde, open a console and run:

$ kdesu XFdrake

enter the root password when prompted and the mandriva graphics configuration utility, XFdrake, should come up. Tick the "Monitor" button, then select Generic Flat Panel 1360x768. Go back and hit the Test button in XFdrake and see if it works. I also think there is something not right in the monitor detection which may be screwing things up. I'm hoping by manually setting it to Generic Flat Panel 1360x768, the problem might go away.

MagnusB · June 20, 2008

Didn't work, don't think it is a issue with the screen detection, I think it has something to do with the nVidia driver. I tried nvidia-xconfig as well, but no change.

pmpatrick · June 20, 2008

Just to make sure I'm on the same page, you have this ViewSonic lcd:

http://www.pcwb.com/catalogue/item/A0419279?cidp=Ciao

If that's the case, nothing jumps out at me in your xorg.conf file that looks wrong. I think the nvidia driver is the likely cluprit. I would check the nvidia ReadMe or errata file if one is installed on your system. There may be something you can do in xorg.conf to work around this problem.

MagnusB · June 20, 2008

It looks like it, but it is actually 15.something, I guess they have just rounded it off. I am pretty sure it has something to do with the nVidia driver, and I just noticed it was a newer version available in the repository (I use 169.12 I think).

But when I installed it, urpmi did not remove the old one, will this matter? I am used to debian based distributions, I feel a bit lost in Mandriva at times, but I can't help loving it :)

EDIT:

That was not a good idea, no X after the "update". Changed to vesa, got actually 1280x1024, I think, which more or less confirmed it to be a driver issue....

ianw1974 · June 20, 2008

I'd hazard a guess that you had the wrong driver. If the newer one didn't work, this could be that your kernel source isn't installed, or that not all of the dkms packages are installed. Or that the newer one didn't support your card.

Do you have all repos enabled? Including the plf-free and nonfree repos?

Also, please post output of:

rpm -qa | grep -i kernel

rpm -qa | grep -i dkms

uname -r

so that we can see what you've got available.

MagnusB · June 21, 2008

This is after removing the newer version of the driver:

kernel-desktop-latest-2.6.24.5-2mnb1
nvidia-current-kernel-2.6.24.4-desktop-1mnb-169.12-4mdv2008.1

kernel-desktop-2.6.24.5-2mnb-1-1mnb1

nvidia-current-kernel-desktop-latest-169.12-1.20080612.4mdv2008.1

kernel-desktop-2.6.24.4-1mnb-1-1mnb1

kernel-headers-2.6.24-6mnb1

kernel-desktop-devel-2.6.24.4-1mnb-1-1mnb1

nvidia-current-kernel-2.6.24.5-desktop-2mnb-169.12-4mdv2008.1

dkms-2.0.19-4.3mdv2008.1
dkms-minimal-2.0.19-4.3mdv2008.1

dkms-nvidia-current-169.12-4mdv2008.1

2.6.24.5-desktop-2mnb

I also compared those nvidia packages to the one available for the newer driver, and found that the nvidia-currrent-kernel was missing. I also ran a test last night, using the Linux Mint 5 live CD, where I could run at 1366x768 using the nv driver (I think, xorg.conf is not complete under a live session, it seems). The newest version in the repositories is 173.14.09, just checked with the nVidia site, the newest available from them is 177.13

And I have all repositories enabled, even PLF, was one of the first things I did, using Easy-Urpmi here. I don't have any of the backports or testing repositories enabled, though.

MagnusB · June 24, 2008

Well, it is pretty much a driver issue. I get the correct resolution if I use nv in both Mint and OpenSuSE 11, but the second I install the nVidia driver, I am thrown back to 1280x1024. This is the case with both 169.12 and the one available through Envy NG, and the one available in OpenSuSE. Seems like I have a choice between accelerated graphics and correct resolution.
