Massive slow down with ATI drivers installed

[TenderBranson]

Hi folks,

I installed Easy Ubuntu 3.021 on top of 6.06 LTS with the ATI drivers chosen as an option. Prior to using Easy Ubuntu, 3d screensavers absolutely flew, and I could use AJAX apps like Google Spreadsheets without a problem. Immediately after installing Easy Ubuntu though, my screensavers slowed to about 1 fps, and using Google Spreadsheets has slowed to a crawl while nearly every website that uses AJAX has seen at least a little bit of a slow down.

I'm more than willing to admit that I might have done something wrong. The first thing I would like to try doing is reverting back to the default driver for ati cards (I have a 9600xt), but I can not find uninstall directions anywhere. Once I figure that out I would like to try installing the drivers again.

Everything else I did with Easy Ubuntu works great! Very nice app, other than this one problem that I am having.

If anyone can help, I'd be most appreciative!

Thanks

Pardon my ignorance, but does this mean that the real ATI drivers have not been installed?

tom@tom-desktop:~$ fglrxinfo
display: :0.0 screen: 0
OpenGL vendor string: Mesa project: www.mesa3d.org
OpenGL renderer string: Mesa GLX Indirect
OpenGL version string: 1.2 (1.5 Mesa 6.4.1)

I'm inclined to doubt that the real ATI drivers use Mesa.

i was getting the same output about my video driver until i ran through the ati driver install. i don't think that the ati driver install is working. check out this link for instructions to get the drivers installed. this will also install glx compiz as well, but you can stop when you get output referencing the ati driver

Have fun!

I also had this problem, Ubuntu should be ashamed of itself, worst driver experience yet.

Anyways.

blacklist old fglrx module from linux-restricted-modules

sudo gedit /etc/default/linux-restricted-modules-common

Edit DISABLED_MODULES to include fglrx
File: /etc/default/linux-restricted-modules-common

DISABLED_MODULES="fglrx"

Now it will say 2.0 mesa not 1.2, and work.

Actually, this is a bug in EasyUbuntu. We are working on fixing it

Thanks for the help guys! Much appreciated!

I tried IronWolves suggestion first, but it didn't help anything. So then I did install the drivers like lorris suggested, and at long last I got this:

tom@tom-desktop:~$ fglrxinfo
display: :0.0 screen: 0
OpenGL vendor string: ATI Technologies Inc.
OpenGL renderer string: RADEON 9600 XT Generic
OpenGL version string: 2.0.5879 (8.26.18)


Well finally Google Spreadsheets are usable (though still much slower than under XP) and Digg doesn't feel sluggish anymore. Unfortunatly though, 3d is still very iffy. Some screensavers run acceptably (but none well), while others are still at the 2-3fps range. I guess I'll just deal with it for now since I'm going to wipe the hard drive anyways. Its kind of a shame though, cause it seems to be that the drivers that came preinstalled were much snappier.

Oh, and if this is a bug in Easy Ubuntu how about at least placing a warning on the download page about it?

Thanks again!
Tom
