[Bug 568711] Re: Resume from suspend does not work

[Martin B.]

I have been suffering from this bug for quite a while but I was able to solve it twice. My setup: Dell 1555, Radeon HD4500, Ubuntu 10.4 64-bit. 
What I had to do in short was: Not to use the fglrx driver that the Ubuntu Hardware Driver addlication offered but to completely uninstall the existing fglrx driver and install the latest driver from the AMD/ATI site.

I performed these steps when running the system in recovery mode, but
that might not even be necessary (but doesn't hurt either).

Uninstall fglrx: 
sudo apt-get purge fglrx fglrx-modaliases fglrx-amdcccle
sudo rm -r /etc/ati /etc/X11/xorg.conf
(from here: http://wiki.ubuntuusers.de/Grafikkarten/ATI/fglrx/Manuelle_Treiberinstallation?redirect=no)

Download driver from here:
http://support.amd.com/us/gpudownload/linux/Pages/radeon_linux.aspx

Run driver installer:
sudo sh ./ati-driver-installer-10-10-x86.x86_64.run      # (in my case)

Initialize driver configuration:
sudo aticonfig --initial 

Reboot...

Not sure wether my situation was *really* related to this bug, but the
symptoms were identical.
