The number of bytes being mmap()ed (12587008 bytes) may well be set in /etc/wodim.conf, where the following line appears by default:
CDR_FIFOSIZE=12m Commenting out this line seems to solve the immediate problem, as only 8192 bytes are now mmap()ed--but I have not tested it with a read CD-R disc, as it seems to me that an 8kB FIFO buffer is a bit small! After some testing (without any blank CD-Rs), it seems that CDR_FIFOSIZE=7788k works, but 7789k does not. I don't have anything that looks relevant in /etc/sysctl.conf or /etc/sysctl.d/*. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1769848 Title: wodim no longer works from non-root accounts To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cdrkit/+bug/1769848/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
