https://bugs.freedesktop.org/show_bug.cgi?id=100306 --- Comment #30 from MirceaKitsune --- Created attachment 132030 --> https://bugs.freedesktop.org/attachment.cgi?id=132030&action=edit Photo of the corrupt image on the screen I have discovered some very important details today. Everyone following up on the report, please see this comment! Recently I realized that a useful test would be to jump into a different run level once I notice the crash, in order to see how the system behaves there. A few minutes ago another freeze took place, so I instantly hit Control + Alt + F1 to go to a console. What I noticed was pretty remarkable and sheds light on a few aspects: I could keep typing in the console for nearly 10 seconds, but after that the exact same behavior still took place (monitor turned itself on and off two times then the image froze). This time however I was able to toggle the NumLock led a minute after the crash, while also seeing the HDD led still working; That means this is not (always) a total system freeze such as a Kernel panic... instead it appears to be the image output corrupting and staying that way, freezing only specific components with it (I was still unable to issue a blind reboot command for instance). To put everything into an approximate timeline, this is what happened: 00 seconds in: The crash occurs. 02 seconds in: I notice and instantly hit Control + Alt + F1. 05 seconds in: I'm taken to a console where everything works fine: I see the blinking cursor, can write my login and password, etc. 12 seconds in: Suddenly the monitor turns off and back on several times, then the image remains frozen in place. This time however, the screen did not remain turned off or black. Instead it stayed stuck in a state showing corrupt lines and rectangles of random colors. I took a photo of my screen with my smartphone, which I attached to this issue. -- You are receiving this mail because: You are the assignee for the bug.
