Previously (incorrectly) reported against kwin here: https://bugs.kde.org/show_bug.cgi?id=309415 I was told to file a new bug against krandr. Reproducible: Always Steps to Reproduce: 1. Open System settings > Hardware > Display and Monitor > Size & Orientation > LVDS1 (Connected) > Orientation. 2. Change this from "No Rotation" to "Mirror Vertically". 3. Click "Apply". Actual Results: The display flashed, the crash window popped up, and the monitor was the same as before. Expected Results: The display to mirror vertically. Setting the display to mirror using the CLI works using either of the following: $ xrandr -o inverted $ xrand --output LVDS1 --rotate inverted Via the GUI, "mirror horizontally" also crashes, but the three rotate variants work fine.
The backtrace from the bug report you linked to is a KWin crash in the video driver. Please add a backtrace for a crash that is related to krandr.
Sorry, I'm not sure how to do that. Could you please explain? Cheers.
I read the linked bug report more carefully, and now I understand the issue.
Thank you for your bug report or feature request. Unfortunately, we did not have a maintainer for the "krandr" components, which are used to manage displays and monitors in the KDE Workspaces. The "krandr" components has been superseded by "KScreen" in newer releases of the KDE Workspaces. It is compatible with all versions since 4.11, and is also used with Plasma 5. Please check with your distribution how to update to KScreen. If this issue or feature request is still applicable to KScreen version 1.0.5 or newer, please add a comment. We will then reassign this ticket to KScreen developers. If you are already using KScreen to manage displays or monitors, and found a different bug or need a specific feature, please create a new ticket for "KScreen" product in this bugzilla using this link: https://bugs.kde.org/enter_bug.cgi?product=KScreen (This is an automatic message from the KDE Bug Triaging Team)
