Kernel team, This default appears to be set in drivers/tty/vt/vt.c to "10*60". Would you be agreeable in changing the default to 0 for all of Ubuntu in the next release (perhaps Zesty+1)? For example we could patch it, or we could add a parameter to make it configurable (either defaulting to 10*60 or to 0), and we could try to upstream any of this.
For desktop (and "client" generally), it should make no difference as X is always running anyway. For server, I think it makes sense for the default to always be 0. IMHO, CRT burn in concerns should no longer govern the default case, and affected users could always set consoleblank back in bootloader configuration. For IoT, in my limited experience it probably doesn't make sense either. Perhaps even upstream would be willing to consider a change to 0 by default? If we don't agree to have Ubuntu's kernel do this by default, then I guess we'll need to do it at packaging level to get the parameter in by default. But I thought I'd start with the kernel default side first as it makes sense to me to change it. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/869017 Title: Ubuntu server enables screenblanking, concealing crashdumps (DPMS is not used) Status in kbd package in Ubuntu: Triaged Status in linux package in Ubuntu: Confirmed Status in kbd package in Debian: Fix Released Bug description: James Rice of Jump Networks noticed that there is a screen-blanker enabled on Ubuntu Server. James notes that this blanking is not enabling DPMS power saving (thereby negating any power-saving benefit), and is simply turning the screen content blank. This means that the crash output is invisible which is unhelpful on a server (virtual or otherwise). Ideally the screen should (at a minimum) be turned on and unblanked at the point of an OOPs/crash being printed.
