Getting poor perfomance in 12.04

**dead5** · September 20th, 2012

I am getting really poor performance while using Ubuntu 12.04 even though i have the latest drivers installed and can run fedora 16 without a hitch. The launcher takes 15 - 30 seconds to respond, switching between workspaces provides poor framerates, basic applications jitter a lot etc.

I am unable to discern the cause for this.

My config is:

Biostar T5XE motherboard
Intel Core i7 860
AMD Radeon HD 5770
4GB ram.

Have you tried using Unity 2D? You can pick that when logging in, by clicking the gear over your username.

Most apps(Eclipse, Rhythmbox, Ninja-IDE, firefox etc) don't perform well in gnome classic either.

If it helps, I am unable to run gnome 3 on Ubuntu although it runs on fedora.

Hi ,
is this a regular installation or wubi ? (from inside windows)

I can imagine two things . First the installation went wrong , or something with graphics driver went wrong.
But you must provide more info.

Code:

lspci -nnk | grep -iA2 vga

Run boot-repair and give here the pastebin link . https://help.ubuntu.com/community/Boot-Repair
second option from a liveCD/Usb.

also

Code:

dpkg -l | grep fglrx

would be helpful .

and

Code:

env|grep DESK

Thanks

I am running a regular installation of Ubuntu.

lspci -nnk | grep -iA2 vga gives

Code:

01:00.0 VGA compatible controller [0300]: Advanced Micro Devices [AMD] nee ATI Juniper [Radeon HD 5700 Series] [1002:68b8]
    Subsystem: PC Partner Limited Device [174b:1482]
    Kernel driver in use: radeon

dpkg -l | grep fglrx does nothing.

env|grep desk gives

Code:

DESKTOP_SESSION=ubuntu
GNOME_DESKTOP_SESSION_ID=this-is-deprecated
XDG_CURRENT_DESKTOP=Unity

Hi ,
If you had the latest drivers installed , the section in bold should be like this

Code:

Kernel driver in use: fglrx_pci

Try to install the AMD's driver . First try from additional drivers (jockey-gtk , from terminal). And try to activate (install) the normal fglrx driver . Not this with updates.

Thanks
