Default Screen freezes temporally with GeForce FX 5500 on Ubuntu Gutsy games

I'm having the same problem as the thread 94874 (http://www.nvnews.net/vbulletin/showthread.php?t=94874) testing these games: Alien Arena, Boson, Frets on Fire, GL-117, Neverball, Nexuiz, Open Arena, Planet Penguin Racer, Scorched 3D, Torcs, Trackballs, Trigger, Vega strike, Warsow.

Motherboard: Asus K8V SE Deluxe
CPU: AMD Athlon64 3200+
GPU: NVidia GeForce FX 5500

Procedure:
1. Fresh install of UbuntuStudio 7.10 (32bits)
2. Update packages and rebooted
3. Enabled new NVIDIA resctricted driver
4. Tested Compiz (works well) and left disabled
5. Installed that games
6. When testing each game the graphics freezes during 5 to 30 seconds, but sound and game runs, and after the game continues normally. This happens each minute (aprox.). If I prepare a SSH console from another computer to see with TOP what do the processes, I see when graphics freezes that the Xorg process is using more than 90% of CPU.

It happens booting both 2.6.22-14-generic and 2.6.22-14-rt kernel.

I've tried to download and install NVIDIA-Linux-x86-169.12-pkg1.run , but it asks for kernel sources to compile something. I've installed the "linux-source" package but the installer stills not being satisfied.

Default Re: Screen freezes temporally with GeForce FX 5500 on Ubuntu Gutsy games

Read

http://www.nvnews.net/vbulletin/showthread.php?t=72490

on how to install other drivers manually in ubuntu.
Ubuntu allready provides two different drivers,
nvidia-glx and nvidia-glx-new, try both of them first.

Then make sure to read instructions carefully,
as otherwhise there will be no X11 for you.

Please provide nvidia with a bug report,
best would be after the error occured.
Read the instructions for bug reports (see sticky posts) first.

Please do also try to disable the composite extension
and similar things.

Default No screens found

Oh thanks, reading the 72490 thread I've installed NVIDIA-Linux-x86-169.12-pkg1.run

* I needed to create a directory "nvidia" manually because the installer failed to create some file (I don't remember the path)

BUT:

- I only can start Xorg if I boot with the same kernel as when installing (2.6.22-14-rt). If I boot with 2.6.22-14-generic Xorg returns a "No screens found" message.
- First person shooter games as Alien arena or Nexuiz now doesn't freeze, but car race games as Trigger and Torcs still freezes (during less time)
- I cannot (?) set a screen vertical frequency higher than 50Hz.
- If I try to set desktop visual effects (compiz), the appearance configuration tool asks to enable nvidia-glx-new driver. Can it be a problem for the actually used driver?

Default Dificult to see TV

Other problems: before of installing the new driver, I could see TV (Pinnacle PCTV stereo card) with TV time, XawTV and zapping applications, but now the TV card is not accessible.

tvtime says:
pwc: Invalid argument
Cannot open capture device /dev/video0

Yes. As the nvidia driver depends on certain things on the kernel it will be compiled against the current Kernel (usually the one /usr/src/linux points to) and only work with this kernel. You can specify another kernel as an option in the nvidia Installer. Please read either the README or the installers help.

Please provide nvidia a bug report,
generated by nvidia-bug-report.sh.
Read the sticky thread on how to report bugs,
but it is rather simple: Just run the nvidia-bug-report.sh script. It will create a file in the current directory.
(g)zip this file and add it as an attachment to your forum post.

Usually the nvidia driver reads out valid and sane
frequencies out of the monitors EDID.
On some monitors this is broken, so you have to add

Option "UseEdidFreqs" "false"

to your device section in the xorg.conf file.

Make sure that HorizSync and VertRefresh
are set to sane values before adding this,
as your monitor might not be able to display
the selected frequency otherwhise, so you end up
with a blank screen. (Switching to a VT with
CTRL+ALT+F1 works)

Please read the Readme file, especially the Appendix
(App. B in current READMEs) with the description
to those options.

Are you sure that the nvidia driver is loaded?
Please check either with lsmod or /proc/drivers/nivida/...

If yes: obviously it is not recognized by ubuntu,
that's why ubuntu wants you to install the driver
provided by ubuntu.

If you are sure that the driver is loaded you can run
compiz manually with compiz --replace --sm-disable --ignore-desktop-hints ccp --indirect-rendering &
on a terminal. I recommend installing and using fusion-icon.

As for the TV card: I can't see any connection to the nvidia driver,
please read through dmesg and /var/log/messages to get a hint
why it is not working anymore.

hope this helps,

Fuchs

Default Advancing

- The problem with the TV card was that using the new VGA driver the video devices order has been inverted: /dev/video0 is now /dev/video1 , and /dev/video1 is now /dev/video0.
How can I restore the original order? (It's for a PCI TV card [0] and USB webcam [1])

- To solve the only-one kernel used by NVidia installer, I've backed up the /lib/modules/2.6.22-14-rt directory, booted with 2.6.22-14-generic and made the installation for this, and after restored the 2.6.22-14-rt that had a good VGA boot.
Now both kernels boot with the new installed drivers, but the behaviour is identic (games, video devices order).

- I've added
Option "UseEdidFreqs" "false"
to the Device section in xorg.conf file, but frequency stills 50Hz in "Screens and graphics" and "Screen resolution" Ubuntu desktop utilities.
Section "Monitor"
Identifier "Monitor genèric"
HorizSync 30.0 - 70.0
VertRefresh 50.0 - 120.0
Option "DPMS"
EndSection
(I don't know if it's the correct syntax, but I haven't written those parameters)
I've open the /usr/share/doc/nvidia-kernel-common/README.Debian file, but nothing appears about HorizSync/VertRefresh and there are'nt any "Appendix" linbe.

- Driver loaded? lsmod command returns some lines about nvidia:
nvidia 7827040 24
i2c_core 26880 5 tuner,nvidia,saa7134,ir_kbd_i2c,i2c_viapro
agpgart 35284 2 nvidia,amd64_agp
Attached Files
File Type: zip nvidia-bug-report.log.zip (28.6 KB, 105 views)

Default NVidia + Xorg = 100% CPU

The problem occurs with or without games, and booting in any way.
Related threads:
http://ubuntuforums.org/showthread.php?t=124450
http://www.ubuntu-es.org/index.php?q=node/45201

I've tried a lot of solutions proposed on internet, but the only effective is returning to non-proprietary driver. Disabling the NVidia proprietary driver the Xorg process doesn't grow consumption in my PC from 3% to 97-99% of CPU.

The problem was produced at any time: using the desktop and not using, playing a game and not playing, with screensaver and without, killing each other processes and not, just booted and started M.Firefox or 2 hours later.
But I've disabled the NVidia's propietary driver 1 month ago, and hadn't any lock nor Xorg collapse.
