[KScreen] [Bug 406099] Second monitor doesn't display
https://bugs.kde.org/show_bug.cgi?id=406099 --- Comment #11 from Nancy Hand --- The next reboot everything works as it's supposed to. So: apply patches, reboot, login screen is invisible. Login blind, both screens appear in KDE. Reboot again, login screen is visible again. Continues to work properly through several patches, then the login screen goes invisible. Usually this happens after a new kernel is applied. The most recent one was not associated with a kernel update. There were 5 or so library (I think) updates. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=406099 --- Comment #10 from Nate Graham --- Okay, now if you reboot again, do both monitors get enabled *after login* as expected, or does one of them fail to display again? -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=406099 --- Comment #9 from Nancy Hand --- Both are plugged into DVI ports. On boot: The monitor that normally displays the login screen is blank. Almost as if not receiving any data but, if I hit return and enter my password, login continues and both monitors display the startup screens. Then the images for the two monitors change over to their "correct in KDE" locations. When looking at the Display Configuration the VGA monitor shows enabled as the secondary monitor and the DVI monitor shows as the primary. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=406099 --- Comment #8 from Nate Graham --- So they are both plugged into DVI ports on your graphics card? And if you manually enable the disabled monitor on the Display Configuration page, it gets disabled again later? -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=406099 nancy changed: What|Removed |Added CC||nnc@gmail.com --- Comment #7 from nancy --- The non-functioning monitor is plugged into the first port. On boot up the system reads this as the primary monitor. Within Fedora I have this set as the secondary monitor. It's an older VGA monitor. The working monitor is plugged into the second port. On boot the system reads this as an "extra" monitor. Within the OS this is set to the primary monitor. This is a somewhat newer DVI monitor. I'd thought they had different connectors on the video board but in looking at it just now, they both have DVI connections on the board. -- You are receiving this mail because: You are watching all bug changes.

The next time it happens, can you paste the output of `kscreen-doctor-o`? Thanks -- You are receiving this mail because: You are watching all bug changes.
