Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free, no registration required.

I have installed latest Ubuntu 64 bit on the hp dc7800 with core 2 duo e6550.

It has 2gb ram. Not a stellar machine, but I'm getting very poor performance.

Windows and applications are slow to open and move.

Checked drivers and it says "no propietary drivers" are installed.

I just flattened and re-installed the 32-bit, as read somewhere that 2Gb is bare minimum for a 64-bit install. 32-bit seems the same symptoms.

What can I do to diagnose and rectify the sluggish performance?

I think the answer is in your question "Checked drivers and it says "no propietary drivers" are installed". Thats were I would start.

To install the drivers

Go to System Settings

Select "Additional Drivers"

Install the Recommended Video driver.

If there are no drivers available check what Video card you have. Open terminal (Ctrl+Alt+T) then paste

spci | grep -i pci || lspci

then

sudo lshw

When you know what video driver you have, search other questions at AU for related issues. I tried to google myself but wasnt successful. Im not sure if being an SFF desktop has any bearing.

Thanks Stephen, it doesn't let me click anything within, just an empty panel with no additional drivers offered. –  evilswan Jun 13 '12 at 15:03

Looks like I have Intel Corporation 82Q35 Express Integrated Graphics Controller (rev 02) –  evilswan Jun 13 '12 at 17:25
    
Thanks for your help - a quick Google around shows that there's no closed-source Linux drivers with 3D acceleration (which would presumably make the desktop much snappier). Also others are reporting sluggish performance as well as artifacts and corruption like me. Might sell this box and get another, better-linux-supported one. –  evilswan Jun 13 '12 at 18:16
