Just bought a Lenovo G570 with a Radeon 6370m video card. Tried both drivers recommended under "additional drivers".
The first driver failed.
Sorry, installation of this driver failed. Please have a look at the log file for details: /var/log/jockey.log
The second driver installed, but when I restarted and went to log in again, my only options were ubuntu and ubuntu 2d. No unity. There were no panels or anything, just a menu that looks like this:
File Edit View Go Bookmarks Help
So... I opened firefox and went to ATI's page to get their latest supported driver for my card. I uninstalled the old driver, restarted and ran the installation script.
sudo chmod +x ati-some-really-long-driver-name.run ./ati-some-really-long-driver-name.run
It said it was successful, but when I restarted - still, no unity, no application dock on the left hand side of the screen, no panels. Just the menu I described above.
