I have a rather old (~2007ish) iMac, which I've recently installed Xubuntu 13.04 (64 bit) on. For various reasons it's important that I'm able to get reasonable 2D graphics acceleration on this machine, and unfortunately
mesa doesn't quite cut it. I've therefore been battling to install the proprietary AMD drivers, but with no success so far.
According to the output of
lspci | grep VGA, I seem to have an AMD Mobility Radeon HD 2600 XT/2700. Looking in Settings Manager > Software & Updates >Additional drivers I don't see any option to install a proprietary display driver.
Things I've tried:
fglrx-updates from the normal Raring restricted repository
In both cases
lightdm doesn't start at all.
dmesg | tail gives me:
[ 21.939526] AMD IOMMUv2 driver by Joerg Roedel <firstname.lastname@example.org> [ 21.939530] AMD IOMMUv2 functionality not available on this system` [ 22.078527] <6>[fglrx] Maximum main memory to use for locked dma buffers: 1873 MBytes. [ 22.078991] <3>[fglrx:firegl_init_device_list] *ERROR* No supported display adapters were found [ 22.078993] <3>[fglrx:firegl_init_module] *ERROR* firegl_init_devices failed
Based on the AMD website and on various other answers on this site, it seems that the Radeon HD 2000 - 4000 series of adapters is no longer supported by the mainline Catalyst drivers available directly from AMD, or the
fglrx packages available from the standard Ubuntu repositories.
2) Adding this repository, downgrading Xserver to 1.12.4 and installing
This time the
lightdm process seems to start, but the display is totally glitched-out (weird moving colour gradients). I see this in
dmesg | tail:

3) Installing the legacy Catalyst drivers downloaded directly from the AMD website
During the installation I get a message saying
DKMS part of installation failed. Please refer to /usr/share/ati/fglrx-install.log for details. The install log says this:
cd /var/lib/dkms/fglrx/22.214.171.124/build; sh make.sh --nohints --uname_r=3.8.0-27-generic --norootcheck......(bad exit status: 1) [Error] Kernel Module : Failed to build fglrx-126.96.36.199 with DKMS [Error] Kernel Module : Removing fglrx-188.8.131.52 from DKMS
It's presumably failing to build because that driver only supports kernel versions up to 3.4, whereas mine is 3.8.0-27.
Is there any way I can get proprietary AMD drivers working on Ubuntu with a Radeon HD 2600 XT? I'm open to other options, such as downgrading my version of Ubuntu or switching to a different window manager. Could anyone suggest any combination of Ubuntu and Catalyst versions that are likely to be compatible?
