[opensuse-factory] Tumbleweed disabling screen blanking when using KVM Switch
I have a hardware KVM switch that I use to switch between 6 computers. On my openSUSE Tumbleweed system running KDE when I switch away from the Tumbleweed system to another system and return my screen is blanked. I have to power cycle the computer to get a screen back. I have Screen Locking disabled in desktop management I have Screen Saving disabled in desktop power management. I have power saving disabled in desktop power management. I have the following in /etc/X11/xorg.conf.d/ 50-monitor.conf Section "Monitor" Identifier "Dummy" Option "DPMS" "false" EndSection Section "ServerLayout" Identifier "ServerLayout0" Option "StandbyTime" "0" Option "SuspendTime" "0" Option "OffTime" "0" EndSection With all this I still have this blanking when I switch away from this hardware with my KVM. This is a HP Intel Core 2 Duo E8400 system Desktop with what hardware info tells me is "Intel Q33/Q35/G33 graphics. How can I solve this issue? I have to be able to switch away from this system and return to a normal display. Steven -- ____________ Apply appropriate technology. Use what works without prejudice.

Just ideas, since I have multiple E8400s, but don't use a KVM: https://bugs.kde.org/show_bug.cgi?id=317929 does not look like it's on point, but it could be related. You may need to find out which kde config file manages screen blanking, in the same fashion that kdedrc can be set to disable kscreen from autostarting, thus respecting xorg.conf* settings for DPI and resolution. It might be fruitful to ask on one of the kde mailing lists, as this shouldn't be an openSUSE-specific problem. Asking there might turn up the existence of an upstream bug on the subject. Maybe more likely the problem is using the identifier "Dummy". Are you using "Dummy" also in 50-screen.conf? I've usually found that 50-device.conf, 50-monitor.conf and 50-screen.conf must have their idents sync'd up to get expected results from any of the three, even those that aren't actually specifying any settings. FWIW, rather than Option "DPMS" "false" I use Option "DPMS" "off", but I think both are supposed to produce the same result. -- "The wise are known for their understanding, and pleasant words are persuasive."

I looked at the bug. Doesn't seem to be related. As a further attempt to get this playing I've edited /etc/X11/xorg.conf.d/monitor.conf to match /etc/X11/xorg.conf.d/screen.conf as far as definitions go. Screen.conf is commented out. I left it that way.

I don't think the Screen Saver is coming into play. I'm not certain I should try to set that to no or if no is even the right switch. Steven -- ____________ Apply appropriate technology.

I wouldn't expect it to absent my comment trying to explain the concept of preventing KDE from ignoring xorg.conf* by preventing it from automatically starting up a KDE component that ignores xorg.conf*. For me that component was kscreen. For screen locking I don't know what component might need to be prevented from starting - maybe there could be something to be put in kscreensaverrc or powermanagementprofilesrc to let Xorg handle power management.
As a further attempt to get this playing I've edited /etc/X11/xorg.conf.d/monitor.conf to match /etc/X11/xorg.conf.d/screen.conf as far as definitions go. Screen.conf is commented out. I left it that way.
I wrote what I wrote for a reason. To ensure any of those three 50-*.conf files do as expected for me has always required all three be in sync, not just 2 out of 3. -- "The wise are known for their understanding, and pleasant words are persuasive."
