During system-setup we currently deactivate the screensaver via 'xset s off -dpms' in usr/share/univention-system-setup/startxwithfirefox. Does that not work anymore?

Doing a "chroot /target xset -display :0 -dpms" on the other hand disabled the screen-saver in my test. "xset s off"+"xset s reset" on the other hand was not enough.

At least the screen-saver is still activated for d-i before uss.

I have added 'dpms=false' to the Linux kernel command line: r18169 | Bug #47090: Disable screensaver But it does not disable the blanking. The X-server is running on the Linux frame buffer, which does not support DPMS: # grep FBIO /var/log/Xorg.0.log [ 2.182] (II) FBDEV(0): FBIOBLANK: Invalid argument (Screen blanking not supported by kernel - disabling) Instead the following seems to work: xset -display :0 s reset # to disable any current blaning xset -display :0 s off # to disable any further blanking This is confirmed by "xset q" and verified by setting a short blanking time with "xset s 10 20". According to <https://wiki.archlinux.org/index.php/Display_Power_Management_Signaling#Setting_up_DPMS_in_X> this can be configured permanently by adding a <file:/etc/X11/xorg.conf.d/10-blanking> with Section "ServerFlags" Option "BlankTime" "0" EndSection r18172 | Bug #47090: disable screen blanking Package: rootskel-gtk Version: 1.36A~4.3.0.201806121805 Branch: ucs_4.3-0 Scope: errata4.3-1 QA: virsh -c utby start phahn_installer # use isotests/ucs_4.3-1-latest-amd64.iso sleep 15m # > 10m which was the old default virsh -c utby screenshot --domain phahn_installer --file 47090.png display 47090.png After QA I can backport it to UCS-4.2, too. This needs to be put on the DVD: either we re-release the DVDs with that modified package or we have to wait until the next patch-level release. Therefore no YAML. changelog.xml for next release: <listitem><simpara>The screen-saver has been disabled while the installer is running <u:bug>47090</u:bug>.</simpara></listitem> OK: No screensaver in debian installer with latest ucs4.3-1 dvd OK: yaml Backport currently not necessary Verified |
