[9800GT] Problem after the installation Nvidia driver

I have fixed the problem, for some reason when I installed the drivers it created a graphical mode for my monitor in 1680x1050 at 60Hz that did not work.

Using nvidia-settings as root I switched the mode frequency to Auto and applied and it fixed the problem straight away. I saved the setting in /etc/X11/xorg.conf and now everything is clear again.

The question now is what did it do that on a fresh install....

It looks like the settings don't stick, I have to go to the nvidia-settings everytime I login, change the frequency from Auto to 60hz and then Apply. Even if I run the tool as root and save the settings after I reboot I have the same issue.

Sounds roughly similar to bug #940742.

I'm a bit confused by your last two comments. In #2 you said you changed the mode frequency to Auto in xorg.conf, then in #3 you have to change it from Auto to 60Hz. Couldn't you just set it to 60Hz in your xorg.conf directly?

Your xorg.conf is not attached to this bug btw, can you attach it?

Hi Bryce,

I changed the setting from Auto to 60Hz in Nvidia-settings but even if I save the config to xorg.conf when I restart the fonts become blurry again.

I have also tried to remove my xorg.conf completely and regenerate one from Nvidia-settings but it doesn't help.

I ran Nvidia-settings as root.

I have attached my xorg.conf. not sure if it is very relevant as I deleted it to try again from scratch several time.

Many thanks,
Fernando

I do have the same problem, tried to write directly the xconf but no luck

Hi,

I did a full re-install today as soon as I installed the nvidia drivers through Jockey the fonts became blurry again at next reboot

Are you able to set the preferred rate via xrandr? I.e.

  xrandr -r 60.0 -s 1680x1050

If so, you could stick that in your .xsessionrc file.

Alternatively, try this in your xorg.conf:

Section "Screen"
    Identifier "Screen0"
    Device "Device0"
    Monitor "Monitor0"
    DefaultDepth 24
    Option "TwinView" "0"
    Option "TwinViewXineramaInfoOrder" "CRT-0"
    Option "metamodes" "1680x1050_60 +0+0; nvidia-auto-select +0+0"
    SubSection "Display"
        Depth 24
        Modes "1680x1050_60"
    EndSubSection
EndSection

Further, make sure you do not have a ~/.config/monitors.xml file (it won't work with nvidia).

When I run "xrandr -r 60.0 -s 1680x1050" I get "Rate 60.0 Hz not available for this size"

I tried the settings in the xorg.conf and it doesn't work either.

I don't have a ~/.config/monitors.xml file

Something worth mentioning is that I am using the VGA Out of the card, not the digital output.

I run xrandr on its own I get the following:
xrandr: Failed to get size of gamma for output default

I notice several bugs reporting similar problems with older nvidia cards: 877438 (8xxx cards), 940742 (6xxx cards), 943643 (9800), 958251 (8600), 962191 (7100). The problems include generally degraded performance, fuzzy fonts, and/or lagging in games, which did not exist in earlier versions of the nvidia driver.

We've recently added a new 295-33 version of -nvidia to Ubuntu. The changelog doesn't specifically list a fix for this type of problem, but it does list a few performance fixes, and would be worth re-testing. Update to nvidia 295.33 and report back here whether or not it improved the performance.

Note, you might be seeing crashes, corruption, or other assorted problems, but these may be separate bugs, let's just focus on the performance regression on this bug report.

Hi Bryce,

Thanks a lot for looking into this bug, I also believe this comes from the nvidia driver itself.

I am already running the new 295.33, I received the update form 295.20 sometime last week I believe

ii nvidia-common 1:0.2.42 Find obsolete NVIDIA drivers
ii nvidia-current 295.33-0ubuntu1 NVIDIA binary Xorg driver, kernel module and VDPAU library
ii nvidia-settings 295.33-0ubuntu1 Tool of configuring the NVIDIA graphics driver

Thanks fmo

Xorg does not work with nvidia-current on my 9800GT.
My graphics card only works with the nouveau driver:

I had the same issue ( 12.04 ) . It was solved when i switched to new monitor D-SUB -> DVI . Fonts were blurry with binary blob but not with nuoveau .

This bug has finally been fixed in latest beta 304.22!
