Ubuntu 12.04 problems with NVIDIA® GeForce® 8400M

So finally I’ve got my old laptop working with the current Ubuntu 12.04 release.

To do this I’ve followed this user advice and completely removed the proprietary NVIDIA driver:


sudo apt-get --purge remove nvidia*
sudo apt-get install xserver-xorg-video-nouveau libdrm-nouveau1a nouveau-firmware

Reference: [8400m] nvidia-graphics-drivers (295.33-0ubuntu1), is causing failed restarts. shutdowns & only a blackscreen on tty’s other than tty7

Ubuntu 8.10 (Intrepid Ibex) in LG E500-SP23P laptop

I’ve done a fresh install of Ubuntu 8.10 (intrepid ibex) in my LG E500-SP23P laptop and I’ll document my troubles and my thoughts about the new Ubuntu version.
I’ve switched to Ubuntu since it’s 5.10 version and in this laptop since its 7.04. My previous version was 7.10 and some of the problems that I had in installing it then, I saw them in this new version too…
This laptop has the following specs:
Processor

  • Code Name: Meron
  • Processor: Intel Core 2 Duo Processor T7500
  • FSB: 800Mhz
  • Speed: 2.2Ghz
  • Cache: 4Mb L2 Cache
Graphic Card
  • NVIDIA® GeForce® 8400M 128Mb VRAM -TurboCache até 384/896Mb
Wireless Card
  • Atheros AR5007EG Wireless (802.11b/g)
Sound Card
  • Audio card Intel Corporation 82801G (ICH7 Family) High Definition
After installing it I’ve noticed that wireless didn’t work. In 7.10 it also didn’t work, so I expected that it should be fixed by now. After some googling I’ve find out how to solve this.
Another problem that I’ve faced was that I couldn’t activate Desktop Effects. I’ve went to System/Apperance and in the “Visual Effects” tab activated “Extra”. Here ubuntu showed me the option to activate the proprietary driver, and I choosed “Enable”.
Activate proprietary driver
Activate proprietary driver
So I choose to “Enable” and another error showed up:
Enable to enable driver
Enable to enable driver
Another problem that I had (I also had in 7.10 version and never could fix it) is that if I plugin headphones, I continue to ear sound from the front speakers.
I haven’t fix this yet, when (if) I do, I’ll let you know ;)
