I Upgraded an Acer Extensa with an integrated nvidia 7050/nv620i, from 10.04 to 12.04.(full reinstall) With the buggy nvidia driver 295.40,the system was unuable.

I downloaded from nvidia site and manually installed the following drivers that doesn't work perfectly:

295.49; 295.33; 302.07 (beta);

The situation was better than 295.40, but still non usable. Moving from one desktop to another keep 2 seconds. Clicking on hour/date applet on top bar, shows the small windows drawing slowly....

What can Nvidia user do ? Is it possible to state which Nvidia series works by sure :

100, 200, 400, 500 ?? Which one ?

For production environment, is changing card brand the only viable solution ?

I am complaining about a card SAID to be supported (discovering that it is false) and ASKING which other nvida card SERIES works PERFECTLY. When running /usr/lib/nux/unity_support_test -p whie get Not software rendered: yes Not blacklisted: yes <-------- .... Unity 3D supported: yes –  Giuliano69 May 12 '12 at 23:19
Thank Uri, but you have MISSED the question. Running /usr/lib/nux/unity_support_test -p and visting nvidia site at nvidia.com/object/linux-display-ia32-295.49-driver.html, the 7050 is said to be supported, but doesn't work. WHAT I asked is WHICH nvidia card family can be used without problem. This means series NUMBERS (8000 ? 9000 ? 100? 200?....). If you don't know which series NUMBER works, please wait someone who knows to give the informations. A "newer card" unfortunately has no information...current motherboard use 7000/8000 cards.. and this are said to be supported... –  Giuliano69 May 12 '12 at 23:39

In 10.04 the following drivers were available:

  • nvidia-96 - GPUs ranging from GeForce series 2 (except for GeForce2 GTS/GeForce2 Pro, GeForce2 Ti and GeForce2 Ultra) to Geforce series 7 are supported
  • nvidia-173 - GPUs ranging from GeForce series 5 to Geforce series 9 are supported
  • nvidia-current (195) - GPUs such as GeForce series 6 or newer are supported

The compatibility notes are directly from the package description (should be 3rd paragraph) and haven't changed much in 12.04. It is worth noting that nvidia-current moved from 180 over to 185 and from there to 195 during the 10.04 life cycle.

Using nvidia-current might have worked very well in 10.04. But you have to understand how Nvidia maintains their proprietary drivers. This is not limited to Linux/Unix drivers and applies to Windows in a similar fashion and AMD/ATI is no different there.

For Linux, Nvidia maintains 3 versions of drivers: One for very old cards (2000-2005, I know that this is not exact, but let's try to keep it as simple as possible) with a very limited set of features, one for rather newer cards (2005-2010) with more features and one with support for the latest cards (2010 onward) and all features they provide. This is done to reduce the maintenance effort as much as possible. If implementing support for a new series or feature breaks support for older cards or makes them unstable, then this is a sacrifice to be made and users of those cards have to switch to an older but still maintained/compatible driver series.

Also you need to know a bit more about the particular chip. Wikipedia says it is a chip from 2007, however Geforce Series 7 was released in 2006 and most low end designs are based on the previous series or even earlier. So actually were talking about a low cost design from 2005 or 2004.

My advice in your case: Remove all old drivers and install the nvida-173 driver, it should be sufficient to run Compiz (I did that back in 2008 with 08.04, version back than was 140 or 160), however the chip may not be fast enough to run Unity, you could try to disable blur in CCSM, if that doesn't help you have to use Unity 2D.

I don't know exactly but I do know that the old 7*** desktop series definetly works.

ADVICE: Uninstall old drivers and install new ones from the nvidia site, the upgrades make a huge difference.

I've used Nvidia through the years and ever since they've had a System Settings function to recommend and provide proprietary drivers, I was successful taking the driver they recommended. My current mobo has a 7025 chip set on it which worked without issue with Ubuntu 11.04. I've upgraded to a 210 board which also works nicely, now with a 1980x1080 monitor and Ubuntu 12.04 with the 295.40 Nvidia driver. I can only speak for what I've myself used.
