My laptop works perfectly fast with Windows 7 but is very slow in Ubuntu 12.04.When I try to open the dash it takes 1-2 sec.even the normal right click on the desktop for the dropdown options is taking time.I installed preload but it made a very slight change. Everything is up to date.

My laptop is : Lenovo ideapad Z560
500 GB hard drive (dual booting win7 and Ubuntu 12.04)
Intel® Core™ i3 CPU M 370 @ 2.40GHz × 4 processor
Nvidia GeForce 310M/PCIe/SSE2
Ubuntu 32 bit

any help?

    Unity dash is quite slow by default, and that's probably the main factor making your feel that the entire OS is slow. Even though there are some ways to speed up dash, it will still be slow even on high-end hardware. Dec 30, 2012 at 12:44

[   26.993526] NVRM: Your system is not currently configured to drive a VGA console
[   26.993530] NVRM: on the primary VGA device. The NVIDIA Linux graphics driver
[   26.993532] NVRM: requires the use of a text-mode VGA console. Use of other console
[   26.993534] NVRM: drivers including, but not limited to, vesafb, may result in
[   26.993536] NVRM: corruption and stability problems, and is not supported.

Did you see that? System does not have proper nvidia driver. It's running in VGA mode. That's why system is not responsive. Open jockey-gtk (default installed), it will automatically show perfect driver for your graphics card. Install it from there. And also remove your existing driver first.

  • This may not be the case. I have the same message on dmesg and I've got the nvidia drivers installed through jockey. It simply doesn't seem to have disabled vesafb. The nvidia kernel module is loaded however and Unity works okay as far as I can tell. Probably not a bad idea to disable vesafb anyway if that message is to be believed

During installation, how much swap partition did you create? Use ubuntu-tweak janitor to clean and cool your Ubuntu and update Ubuntu using update-manager.

  • Let's not go as far as swap partitions... the dash is slow because of ridiculously lame animations. We have far cooler blur & stuff demos 10 years ago in 1k demos, but nowadays we need hardware acceleration to perform a blur.
