Open GL error. Can't start TF2

[1 3]

Hi I recently installed linux ubuntu 12.04 on my imac. I tried staring TF2 but it gave me a open gl error saying something about gl_ext_texture_srgb_decode. How do I fix this? I'm new to linux so detailed solutions would be nice. I also have a radeon 2400 HD gpu.

Have you installed the proprietary drivers or are you using the default open source ones?. System administration --> Additional drivers should do it.

I already installed the additional drivers ati thing.

The radeon 2400 HD needs the newest legacy drivers, which are not in the official repositories yet ( i think ).
There are instructions here for 12.10, http://ubuntuxtreme.com/howto/how-to-fix-your-amd-graphics-in-ubuntu-12-10/
but you're in 12.04.
I think you'll have to install the driver yourself.

Thanks but how do I install the drivers correctly? Do I just un zip them?

Actually, you might be able to use this ppa:

From a terminal, run the following:

sudo add-apt-repository ppa:makson96/fglrx
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install fglrx-legacy

Then reboot.

I did all of the commands but the last one says it was unable to locate package fglrx-legacy

I hoped that would work. The PPA is for 12.10 but I found someone saying it was working on 12.04 too.

Can you try rebooting and trying again? I sincerely doubt it will work, but just in case. Otherwise it's manual driver install time.

Yep it didn't work again. So how do I manually install the driver? Also thanks for the help so far :)

Manual driver install:

//this command downloads the driver
#wget http://www2.ati.com/drivers/legacy/amd-driver-installer-catalyst-13.1-legacy-linux-x86.x86_64.zip

//this command unzips the driver
#unzip amd-driver-installer-catalyst-13.1-legacy-linux-x86.x86_64.zip

//this command removes any other ATI drivers
#sudo apt-get remove fglrx*

//this prepares the system. There's a lot of stuff in here and it would take all day to explain it
#sudo apt-get install debhelper dh-modaliases execstack build-essential cdbs fakeroot dh-make debhelper debconf libstdc++5 dkms linux-headers-$(uname -r)

//this actually does the install
#sudo sh ./amd-driver-installer-**-*-x86.x86_64.run --buildandinstallpkg

//this configures it.
#sudo /usr/bin/aticonfig --initial

After this, reboot.

Okay I quess it worked but now I'm getting a new error. It says to require open GL extension "GL_EXT_texture_compression_s3tc" is not supported please install S3TC texture support.

[Anorak Man]

Which one worked? The PPA or the manual install?

[1 3]

Manual install.

[Anorak Man]

Ok. Can you please run steam from the terminal, and paste the output from steam to here?

[1 3]

How?

Oh crap I thought reinstalling the ati drivers form te additional drivers thing would fix the problem but it just gives me the same problem with the srgb texture thing.
