I'm having a critical issue on my production machine. Until yesterday, I've been working with my laptop connected to an external display through HDMI. Now, when I switch the pc on, the display says "no signal". If I book in Windows7, everything works.
What can I do?
Thanks a lot!!
Same thing happened to me today, but I got the display back by booting with an older kernel. Obviously not a good fix, but works as a temporary workaround.
Not sure yet what's causing it. Haven't had any kernel update since yesterday, but I did install a java package that pulled in som X11 libraries. No idea yet if it's related, but I'll try to do some checking. Will update if I find something
