Public bug reported:
Hi
After upgrading, I am nolonger able to hotplug a 2nd screen to my
laptop. The screen corrupts and I have to change to a terminal to do
anything. This happens when the 2nd screen is on or off and unplugging
the 2nd screen without shutting down. Booting with the 2nd screen
attached does solve the issue. "sudo pkill Xorg" also solves it, but I
loose my session.
I've deleted ~/.config/monitors.xml, reconfigured Xorg an the Xorg intel
driver, xrandr and a nomodeset option in grub ( creates a no 2nd screen
connected).
This morning I'm stuck on mirrored screens and any attempt to change it
corrupts the display until I deleted .config/monitors.xml.
Laptop: Samsung NP300E5C
CPU: i5 - 3210m
GPU: 3rd gen intel
Ram: 12 GB
drivers: libva- intel-vaapi-driver, xserver-xorg-video-intel
Monitors:
1. LG 21" LED on VGA - seen as a Goldstar 20"
2 Sinotec 32" LCD on VGA and HDMI - seen as a 40"
Reproduction: Easy plug/unplug a 2nd screen while in desktop or
terminal(switching back to desktop).
Will upload short videos of the LG when I get them of my phone.
The bug was uploaded in terminal while tty7 was flashing away.
I suspect that it's config cruft still on the laptop from saucy, like
the rest of the clean-up I have been doing.
