Since today my external monitor freezes every 10 minutes. I have searched and found that it happened to many other people using Ubuntu (see here and here).
It is really strange because it never happened to me before today, and I don’t remember changing significant things in the middle.
Have you tried to boot using an older kernel? If not, can you try? Maybe that will show a different result.
I haven’t, and I don’t really know how to do it. Could you provide a link or explanation?
Also, what kind of computer are you using? What monitors?
The computer is an MSI Vector GP68HX 12VH laptop. The first monitor is that of the laptop computer.
The second monitor is an external one: LG 24MP 400-B (nothing special really)
This is quite strange and may well be due to a recent update (that is why it will be a good idea to revert to a previous kernel and try). It never happened before and now I can only use the 2nd monitor for a few minutes before it freezes. When that happens, I can avoid forced restarting by setting Lubuntu back to one monitor. I have reinstalled Lubuntu because I thought I had touched something and messed up, but now I have the “standard” installation and it happens again.
So, I will research how to revert to a previous kernel.
Any information/help on that will be useful.
Thanks
