The shell script in the workaround failed here. The awk command produced a \x5b that sed choked on. So, I tweaked the awk script to bracket its output as sed character classes; that let the script finish, but I wound up with a corrupt fglrx_drv.so and had to drop into recovery mode, uninstall fglrx, then boot in to low graphics mode and reinstall it.
However, the thread in http://ubuntuforums.org/archive/index.php/t-2074962.html led me to a workaround that did succeed. I grabbed the /etc/ati/control from a 12.10 install that was running on the same system, copied that to the 13.04 system, and the watermark is gone. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1098561 Title: "Unsupported hardware" watermark appears when FGLRX is installed on 13.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/fglrx-installer-updates/+bug/1098561/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
