I tried to run Briquolo, but it crashed. I believe that my OpenGL installation/configuration may be flawed in some way, or my NVIDIA drivers may be badly installed.

Binary package hint: briquolo

I think that the installation of my NVIDIA drivers may be bad / 'broken'.

In System Settings --> Monitor and Display --> Hardware tab, I configured the driver for my graphics card as nvidia proprietary. But then my resolution went from 1024x768 to 640x480 on next X startup. I ran "sudo dpkg-reconfigure xserver-xorg", and that got my resolutions back.

If I run Briquolo in Konsole, the following text comes up:
BRIQUOLO v0.5.5

Essai r�solution : rMask=8 gMask=8 bMask=8 BPP=32 => Echec

To exit, I must close Konsole.

When I try a different game, Emilia pinball, I get this error (running it in Konsole):

Thank you for your bug report.

FSHero:
What is the output of
dpkg -l nvidia-glx\* | grep ii
and
lspci
?

[Sitsofe Wheeler (sitsofe)]

FSHero:
Oh and how did you install the binary drivers?

[FSHero (minesh-fshero-mistry)]

Easy part first... the output of dpkg -l nvidia-glx\* | grep ii

fshero@fshero-p2:~/download$ dpkg -l nvidia-glx\* | grep ii

(What does that command show, anyway?)

Output of lspci:

(I think I see where this is going... that first command showed that the drivers are version 71.84. But only recently did NVIDIA 'banish' the Geforce 2 to "legacy status"... is this correct?)

Thanks for the quick reply!

[FSHero (minesh-fshero-mistry)]

Okay, I need to stretch my memory a bit to explain how I installed the drivers.

First, I went to the Add/Remove Programs. I ensure that the "proprietary software" check-box was ticked. I searched for NVIDIA, then checked the "NVidia binary X.Org 'legacy' driver" option. I clicked "Apply". It seemed to install something.

I then went to System Settings --> Monitor and Display --> Hardware (tab). Under Graphics card, I clicked Configure. In the hierarchical list, I went to Drivers, then nvidia. (I think it was nv, previously.) I Selected the Proprietary radio button, as I thought that this would give me the 3D acceleration I wanted. After applying the settings, restarted the computer.

Upon rebooting, my display showed a 640x480 resolution. (It was a desirable 1024x768, previously). After a bit of searching, I came upon this document:
http://doc.gwos.org/index.php/Latest_nvidia_feisty

After skim-reading it, the instructions seemed simple and logical enough, so I went ahead and followed "Method 1". I followed the instructions to get the Legacy drivers (71.84). Everything went fine, except
sudo nvidia-xconfig --no-composite
This showed an error message of some sort, which I cannot remember. However, I think I tried:
sudo nvidia-xconfig
(i.e. o arguments.) I think this worked -- no error messages came up, as far as I can remember.

I restarted the X-server, but again, my resolution was the sub-optimal 640x480. I read ahead to the troubleshooting section, and read the short section on resolution problems. I followed the link (http://doc.gwos.org/index.php/ChangeResolution), and followed the instructions.

After running "sudo dpkg-reconfigure xserver-xorg" and answering the questions it asked, my resolution was back to 1024x768. I was happy :)

However, I tried to run the aforementioned games (Briquolo, and Emilia pinball). They did not work. Also, when I run K-Menu --> System --> NVIDIA Settings, I get only get a few options (I would have expected more...). See my file attachment, above.

P.S. I will be away from this Ubuntu computer for a week, so I will not be able to reply to this until then. I hope the above helps, nevertheless.

FSHero:
You don't need to use nvidia-legacy (which is the 7xxx series of drivers). Your card is compatible with nvidia-glx (which is the 96xx series of drivers). See http://us.download.nvidia.com/XFree86/Linux-x86/1.0-9755/README/appendix-a.html . You may have been better served using restricted-manager as mentioned in https://help.ubuntu.com/community/BinaryDriverHowto/Nvidia . The resolution problem is also mentioned on that link and is mentioned in Bug #91292 (although the sudo dpkg-reconfigure xserver-xorg is not mentioned in that bug and is a good tip).

nvidia-settings doesn't work with the nvidia-glx-legacy drivers which is why the window is empty.

Can you uninstall nvidia-glx-legacy, install nvidia-glx, remove the file /lib/linux-restricted-modules/.nvidia_legacy_installed , reboot, log into X. Can you then run glxinfo and glxgears and report back the results? Can you also upload the /etc/X11/xorg.conf and /var/log/Xorg.0.log produced at the end of all this?

This is more of a support query than a bug report though and you may have received a faster/better response using one of the methods described on http://www.ubuntu.com/support/communitysupport rather than bugs.launchpad.net ...

[FSHero (minesh-fshero-mistry)]

Sorry about the unnecessary posting; I got carried away in my excitement of using Ubuntu... !

Should I still post the mentioned files?

[Sitsofe Wheeler (sitsofe)]

FSHero:
Yes if you are following all the instructions in the previous comment...

[FSHero (minesh-fshero-mistry)]

I did what you said in the post, using "sudo apt-get remove nvidia-glx-legacy", and "sudo apt-get install nvidia-glx". This worked. However, there was no "/lib/linux-restricted-modules/.nvidia_legacy_installed" file. (I only remembered this step after rebooting, though...) I can run my games, and the glxgears!

Attached are the results of glxinfo and glxgears. Also, while glxgears was running, I saw a picture of some gears rotating. (I assume that's normal! :D)

Attached are my:
/etc/X11/xorg.conf
/var/log/Xorg.0.log

[FSHero (minesh-fshero-mistry)]

Woah, got to add attachments in separate posts.
Attached: /etc/X11/xorg.conf

[FSHero (minesh-fshero-mistry)]

Attached: /var/log/Xorg.0.log

Again, sorry for not consulting the Ubuntu forums. So... when is it appropriate to post a bug report.

Finally, thanks for helping, Sitsofe Wheeler.

FSHero:
It's not just the forums that you can go to - there's IRC and http://answers.launchpad.net/ too. Generally speaking you file bug reports when you know what is causing the issue and have reproducible steps that _someone else can follow_ to reliably reproduce the issue. This allows you to file the bug in the right package (in this case although you saw a problem with briquolo I suspect the right package was probably linux-restricted-modules-2.6.20). http://live.gnome.org/BugzillaGuidelines contains a good description of what needs to be in a bug report. If it turns out that something that originally looked like a support request turns out to have a clear underlying bug then bugs can be filed.

Thanks for following up on this. Closing because previous comments suggest the issue has been resolved.
