Segmentation Fault when trying to install ATI drivers

[FrederikNeertoft]

Hello guys. I recently installed Ubuntu Lucid 10.04 64-bit on my desktop.
I was trying to install the ATI Drivers for my graphics card (ATI Radeon HD5850) by using the guide:
Search on google for "Ubuntu Lucid Installation Guide", from wiki.cchtlm.com
Unfortunately I cannot post links yet.

I was using the manual install guide. I followed the guide step by step and everything went OK without any errors, until I get to this step: fglrxinfo

And it returns with a "Segmentation Fault"

Any thoughts on this? Help would be greatly appreciated

Did you try installing the drivers provided by Ubuntu? System>Administration>Restricted Drivers or something like that. From the link you mentioned. See the section titled "Restricted Drivers Manager".
It also says

Test your installation

Reboot or fglrxinfo gives an error message. From a terminal window (minimal install must first start x-terminal with 'xinit'), type

I just uninstalled the drivers I tried to get to work, and installed the drivers provided by Ubuntu instead. (System>Administration>Hardware Drivers)
and it tells me that I have the ATI/AMD proprietary FGLRX graphics driver installed, and that the driver is Activated and Currently in use.

I suppose I'm all set up then? Any way to double check that the drivers are actually in use?

I have never used an ATI card so I am not certain this works but it certainly won't hurt to try.

sudo glxinfo |grep -i rendering

Try running glxgears

glxgears

This not much more than a tool to show that opengl is working and the frames per second...it's not exactly a benchmark or anything.

[FrederikNeertoft]

Tried both of them, this is what I got

frederik@frederik-desktop:~$ sudo glxinfo |grep -i rendering
[sudo] password for frederik:
sudo: glxinfo: command not found
frederik@frederik-desktop:~$ glxgears
The program 'glxgears' is currently not installed. You can install it by typing:
sudo apt-get install mesa-utils

[MikeTbob]

sudo apt-get install mesa-utils

And try again.

It seems to be working now. Thanks a lot Mike.
