Display Setup after power failure
The configuration on a Slackware 14.2 64 bit system, is three 1920x1080 displays in portrait mode. Running KDE, I have used the size and orientation tool to setup the monitors so that they are properly oriented and butted adjacent to each other, with the first display starting at 0,0.
I had a power fail last night, and have two problems: 1. The displays will not "butt up" to each other, even though I select the position to be to the "right" of the previous monitor in sequence. 2. The third display can be selected to be to the right of the display to the left, but upon using "apply" will end up to the right of the first display, not the second. Having messed with this a bit, I thought I would ask for help, as perhaps someone has seen this configuring displays. |
Sounds to me like another instance of corrupted KDE caches. I don't know where KDE keeps or what it calls its krandr/kscreen cache, but I'd give a try at deleting the content of ~/.local/share/kscreen/ while logged out of your KDE session. If that didn't work I'd next delete all of ~/.cache/*.kcache , and if that didn't work I'd delete all of ~/.cache/*. Failing that I'd start attacking the mess KDE makes in ~/.config/.

You're not using the proprietary NVidia driver, are you? Of so, there could be something in its xorg.conf interfering.
I never use a DE's utility to configure my own multiple displays. It may be more work, but xorg.conf and/or xrandr in a startup script are pragmatic approaches when using multiple DEs. And, they survive caching, DE and WM bugs. Here's one of the last xrandr "scripts" I used for triple: Code:
xrandr --dpi 120 --output DP-1 --mode 2560x1440 --primary --output HDMI-3 --mode 1920x1080 --above DP-1 --output HDMI-2 --mode 1920x1200 --above HDMI-3 |
