Ubuntu 12.04 Slow Graphics

rated 0 times [ 2] [ 0] / answers: 1 / hits: 6771 / 1 Year ago, sat, march 11, 2023, 7:03:34

I've been having slowdowns in Ubuntu since upgrading to 12.04, sometimes even freezing and crashing my PC. I'm using an AMD Athlon II X2 with 3 GB ram, and an ATI Radeon HD 5670.

I've already installed the ATI drivers from their website but I'm not sure if it uses the driver. From system settings > details, it shows up as VESA - REDWOOD.

UPDATE:
Here are the results of running 'glxinfo' and 'fglrxinfo'

$glxinfo

server glx vendor string: ATI

server glx version string: 1.4



$fglrxinfo

OpenGL vendor string: Advanced Micro Devices, Inc.

OpenGL renderer string: ATI Radeon HD 5670

So, I suppose I have the ATI driver? But it still freezes or slows down occasionally, is anyone also experiencing this on Ubuntu 12.04 with ATI graphic cards?

Thanks!

It looks like your graphic card is running VESA wich maybe causin your problems.

You should reinstall the graphic card driver with 3D support.

Users with ATI cards have the following driver options:

vesa - very basic, lacks 2D/3D acceleration, and focuses on compatibility with all VESA-compliant graphics cards.

ati - actually a thin wrapper that will invoke the radeon driver (or another ati open-source driver for pre-Radeon cards).

radeon - open source driver supporting all Radeon cards. This driver has excellent 2D acceleration and compatibility with the Linux graphics stack. 3D acceleration is sufficient for desktop effects and a nice set of native Linux games. Power management is now comparable to the Catalyst driver.

Instalation

sudo add-apt-repository ppa:ubuntu-x-swat/x-updates

sudo apt-get update

sudo apt-get install fglrx

Catalyst (a.k.a fglrx) a proprietary "blob" (closed source binary) driver designed by ATI, with 3D code based off of their Windows driver. Only RadeonHD chips are supported on recent Linux distros.

Instalation

sudo apt-get install build-essential cdbs fakeroot dh-make debhelper debconf libstdc++6 dkms libqtgui4 wget execstack libelfg0 dh-modaliases

If you're running 64bit

sudo apt-get install ia32-libs

cd ~/; mkdir ATI; cd ATI/

wget http://www2.ati.com/drivers/linux/amd-driver-installer-12-2-x86.x86_64.run

sh ./amd-driver-installer-12-2-x86.x86_64.run --buildpkg Ubuntu/precise

sudo dpkg -i fglrx*.deb

sudo aticonfig --initial -f

Reboot and done.

Great info here.
