I was running into this same issue while trying to copy a CD in K3B (in Pop!_OS 18.04 LTS).

[Bug 1769848] Re: wodim no longer works from non-root accounts
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
[Bug 1769848] Re: wodim no longer works from non-root accounts
Further to my last comment, I'm wondering whether the actual number of bytes that can be successfully mmap()ed is determined by how many other pages are already mmap()ed. Therefore I've set CDR_FIFOSIZE=6m in my /etc/wodim.conf. Hopefully that will work--I'll test it next time I have a CD-R to burn! -- 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
