Title:
Laptop monitor display incorrectly after plug in an external monitor
Status in “xorg” package in Ubuntu:
Expired
Bug description:
----
After I plug in a external monitor to my laptop, and change some
display settings, the screen of the laptop displays abnormal.
A possible reason of this issue is about change resolution to a un-fit
resolution, such as from 1366x768 to 640x480. Or change refresh rate
to some strange number, such 59Hz.
Since all behaviour is normal if without external monitor, thus this may be
due to two monitors can't be sync together. I think such changes should be
allow to sufficient user's
preference.
Steps to repeat:
1. plug in an external monitor
2. Open Display Preference Application on the laptop
3. Change resolution from 1366x768 to 640x480
4. Change refresh rate to 59Hz
What happens:
Laptop screen outputs some garbage data on the right-upper part, some part of
screen didn't display correctly.
What should happen:
Any changes about resolution or refresh rate should display correctly after
plug in a external monitor.
