It starts full screen. I change screen resolution from one resolution to another, I repeat that process many times. At one point, my LCD will show message about out of range input signal. I switch to console and back, and see normal resolution. Sometimes this doesn't work, and I am forced to reboot the system. I attack the output of intel_reg_dumper when screen output goes out of range.

Yakui, can you take a look (assuming this still happens).
Hi, Will you add the boot option of "drm.debug=0x04" and attach the output of dmesg? (It will be better that i915 is compiled as built-in kernel module) It will be great if you can also attach the following outputs: a. xrandr -q --verbose b. vbios.dump. It can be obtained by using the following commands: 1. echo 1 > /sys/devices/pci0000:00/0000:00:02.0/rom 2. cat /sys/devices/pci0000:00/0000:00:02.0/rom >vbios.dump 3. echo 0 > /sys/devices/pci0000:00/0000:00:02.0/rom Thanks.
As there is no response for more than two months, this bug will be rejected. If the issue still exists, please reopen it again.
This bug does still exist. Sorry for no cooperation, it is really my fault. I don't have much time now, but I do all tests eventually.

I can't seem to reproduce that currently. Stars aren't aligned or something like that.... I keep drm.debug=0x04 around untill this shows up again
Hopefully it'll stay fixed, thanks.
Indeed. Despite a lot more tries, this bug just disappeared. The only thing I updated then was libX11.... So indeed, this is right to close that bug
