*facepalm*

Glxgears is not a benchmark!! You get 60fps for an entirely different reason, the exercise of finding out what reason is up to you.

For eff's sake, someone should delete glxgears off the face of the planet! People have been preaching "glxgears is not a benchmark" for years, and yet people still go at it.
Even worse are the people who go "I know glxgears is not a benchmark, but...". Gaaaah, if you know it's not a benchmark, then why are you using it as one??!!

Try reinstalling 302.07, but make sure that you stop the lightdm service as a first step. You may also have to uninstall the previous driver by hand before installing the new one. It took two tries for me to get 295.33 installed correctly. Once it was running correctly, I didn't have any difficulty with 302.07.

Gusar,

I know glxgears is not a benchmarking app, but as it is available to anyone running Linux, it is useful as a comparison. Obviously, I'm not getting 1000 frames per second out of this old card using 295.33, but it shows it is better than using 302.07 (and that is backed up by the real-world "feel" of the user interface).

As a follow-up to my previous post, I tried to revert to the Nouveau driver, but failed abysmally I either had no GUI at all, or when I did, it was in low-graphics 640x480 mode. In the end, I reverted to the 295.33 driver, which is now running very quickly (no GUI lag opening menus or flipping workspaces)

Now, do I risk this stable system by installing 302.07, as Tanker Bob seems to have had better fortune when his 295.33 was stable...

And yet you used it as one. Exactly the crazy mentality I don't get.

What do you think benchmarking is, if not comparing? So no, glxgears is *not* useful as a comparison. Your case is a perfect example. Glxgears showing 60fps has a completely different cause than some performance issue.

Like I said, the 60fps has a completely different cause. So the glxgears number didn't tell you anything. Search around, where the 60fps comes from. And then hopefully you'll facepalm yourself.

Also, let's examine your numbers further: You said 600fps with nouveau, but 1000fps with nvidia-295.33. But you had lag with nvidia. How is that possible, glxgears showed a higher number!
Now you said you're back with nvidia-295.33 but suddenly no lag anymore. Well, what's the glxgears number now, same isn't it?

Conclusion: The glxgears number is completely meaningless. And saying it's not a benchmark but it's useful as a comparison is just dumb. Benchmarking *is* comparing!

I've done this dance so many times. And I'll probably have to continue to do so. It's an exercise in masochism, that's what it is...

Gusar,

I get what you're saying now about glxgears - it's probably an old (bad) habit I have from when I started using Linux in 2005, as a way of checking whether DRI was working (the good old days! )

I see what you mean about the fps figures being unrelated to the lag - the current 295.33 installation is giving approx 750fps in glxgears, yet the GUI is as responsive (if not better) than with nouveau. I admit it - a facepalm moment! As I said above - a force of habit, rather than a useful comparison.

As an aside, when did the '--i-know-glxgears-is-not-a-benchmarking-tool' (or equivalent) switch become the default action for glxgears?

On a final note, I'm happy either way - the GUI is responsive, and 3D apps are now working!

I have an 8800GT, x86_64.

I've been getting hard freezes ever since I upgraded from Kubuntu 11.10 to 12.04. I don't recall what driver version 11.10 was using, but in 12.04 I've tried 295.33, 295.40 and 302.07 and they all lockup randomly.

Usually the freeze happens while I'm away from my PC, which is when a random OpenGL xscreensaver app is running. But lockups occasionally happen when I'm working on the machine. Most of the time the freeze is complete -- the kernel doesn't even respond to any SysRq magic keys.

For now I've returned to 295.40, just to keep the Ubuntu upgrade path clean (also, when I installed 302.07 I was getting "API mismatch" log messages). I've also disabled all the OpenGL and DPMS stuff I can find, as I need this machine to be stable so I can get some work done! If I get another not-too-deep freeze I'll post a bug report.

Please open a new thread if you have any unrelated issues such as the one you just described. Do not bump this thread; it is now irrelevant as both issues it encompassed are fixed in the new 295 and the new 302 release.

Question Re: Please do not use 295.40 or the security patch with GeForce 6, 7 or 8800GTX/GTS c

Hello, I'm a having a similar issue in Ubuntu 12.04 (64bits) as momann and marcnarc describe above (system freezes), but I see this is not the right thread for those issues. (but searches bring me here)
Can you please point me to the right thread?

Thanks, cheers!
Edit: I tried the 32bit version and it's also having the same problem

Re: Linux x64 Geforce series 7 drivers
Are there any planned releases after 295.49 on 6th May? There are still a lot of bugs reported and I'm not sure if anybody is working on them.

I finally managed to get 295.40 installed via the Ubuntu repositories and so far it has solved my problems; locking up, slow, distorted video etc.
Been running for 2 days OK.
