Drivers for AMD (ATI) Radeon HD 5670 in Ubuntu 12.04 LTS (Precise Pangolin).
Hello,
I've got problems with my AMD (ATI) Radeon HD 5670 in Ubuntu 12.04 LTS (Precise Pangolin).
I had 2GB of RAM (DDR2, PC6400, 800MHz), I added another 2GB so now I have 4GB (2x2GB) and I'm not able to use fglrx drivers.
I've applied patch for new kernel http://phoronix.com/forums/showthrea...86-32-bit-arch and installed latest Catalyst 12.4 drivers succesfully without any errors according to WIKI pages http://wiki.cchtml.com/index.php/Ubu...TI.27s_site.29 but unfortunately after system restart I get black or violet screen and I'm not even able to switch to other virtual console with Ctrl+Alt+F1...F6. When I remove 2GB (only 2GB left) system starts normally and everything works fine.
It's not RAM issue, because I've got Windows 7 installed as well and it works fine, 4GB of memory are visible in the system. Besides when I installed Backtrack 5 which is based on Ubuntu 10.04 LTS, 12.4 catalyst drivers were working correctly with 4GB RAM inserted.
All installations were made on fresh and updated system. After I install drivers and execute
Code:
sudo amdconfig --initial -f
fglrxinfo output and xorg.conf (before this command there was no /etc/X11/xorg.conf) are as follows (right after installation and before system restart):
Code:
przemek@pc:~/catalyst12.4$ sudo amdconfig --initial -f
Uninitialised file found, configuring.

I moved xorg.conf file to see if it causes problems, but after
Code:
sudo mv /etc/X11/xorg.conf /etc/X11/xorg.conf.disabled
the problem was still present- black or violet screen.
After xorg.conf restoration
Code:
sudo mv /etc/X11/xorg.conf.disabled /etc/X11/xorg.conf
I tried to tune it according to wiki
Code:
sudo amdconfig --tls=0
sudo amdconfig --acpi-services=off
but without success...
Blacklisting radeon modules also did not help...
Code:
echo "blacklist radeon" | sudo tee -a /etc/modprobe.d/blacklist-radeon.conf
sudo depmod -a
Ofcourse when I remove 2GB RAM and leave 2GB- system boots normally and fglrxinfo looks very good:
Code:
przemek@pc:~$ fglrxinfo

Problem is present only when 4GB are inserted... I borrowed 1GB of RAM and tested configuration with 3GB and it was working fine!
Used kernel supports 4GB of RAM (visible after free -m when fglrx drivers are not installed)
Code:
przemek@pc:~$ uname -r
3.2.0-25-generic-pae
przemek@pc:~$
The same situation is with fglrx drivers from repos...
What kind of logs can I check? Can anyone help me with this issue?
Looking forward,
Przemek.
P.S. I tried also 12.6 Beta version of catalyst drivers, mentioned patch was not need to successfully generate packages, but after installation situation is still the same- black or violet screen when 4GB are inserted...:confused:
