Bug#787279: Cannot disable screen blanking with Jessie preseed installation



Package: debian-installer (i386)
Version: 20150422
Severity: normal
Tags: d-i

With preseed installation (bare metal) of Jessie screen goes black in 10 minutes though there is parameter "dpms=false":
APPEND vga=788 auto=true priority=critical interface=eth0 url="" href="http://192.168.0.100/preseed_jessie.cfg">http://192.168.0.100/preseed_jessie.cfg initrd=netboot_debian_jessie_32bit/debian-installer/i386/initrd.gz netcfg/dhcp_timeout=120 hw-detect/load_firmware=false dpms=false desktop=xfce suite=jessie

Same situation with installation (bare metal) without GUI, even the consoleblank=0 does not prevent screen to go blank:
APPEND vga=788 auto=true priority=critical interface=eth0 url="" href="http://192.168.0.100/preseed_jessie.cfg">http://192.168.0.100/preseed_jessie.cfg initrd=netboot_debian_jessie_32bit/debian-installer/i386/initrd.gz netcfg/dhcp_timeout=120 hw-detect/load_firmware=false dpms=false consoleblank=0 tasks=standard suite=jessie

Is that timeout hardcoded to d-i, consoleblank=0 has no effect, and no X on CLI install?
After installation adding consoleblank=0 to /etc/default/grup && update-grub works normally.

Not a critical thing, but its annoying to keep hitting the key to power up display to see how the installation is going.
IMHO whole screensaver feature could be disabled, it was usefull with old CRTs, but dont think it's needed nowadays... more of a nuisance.
