[Bug 1875240] Re: vbetool: mmap /dev/zero: Operation not permitted Failed to initialise LRMI (Linux Real-Mode Interface).
Mistakes were made. (a) sudo mount -o remount,exec /dev Works. The mistake made was rebooting before testing vbetool.

That's a negative: sudo mount -o remount,exec /dev sudo reboot results: [dreaddy@thing ~] :) sudo /usr/sbin/vbetool dpms off mmap /dev/zero: Operation not permitted Failed to initialise LRMI (Linux Real-Mode Interface).

Re: [Bug 1875240] Re: vbetool: mmap /dev/zero: Operation not permitted Failed to initialise LRMI (Linux Real-Mode Interface).
To assist with debugging please try both of these options (individually) from a clean state: (a) sudo mount -o remount,exec /dev (b) sudo setsebool -P mmap_low_allowed (ie. boot, test, reboot, test the other). Do either of those work? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1875240 Title: vbetool: mmap /dev/zero: Operation not permitted Failed to initialise LRMI (Linux Real-Mode Interface).
